During the atmospheric rivers of early 2023 we had 2 large trees uproot and fall down the hillside behind our home. We also experienced a landslide that left our deck pier and foundation exposed. It was a very scary time for us but Dan Yust and his awesome crew saved the day. They're a very busy group but were able to squeeze us into their schedule. They built a concrete retaining wall, repaired the landslide area and installed drainage pipes to allow water to flow properly. They were responsive and communicated well. They also cleaned up nicely once the project was completed. This was not an inexpensive endeavor but when you're trying to save your house and property, I consider it money well spent. I highly recommend Acustruct. read more

AcuStruct - Concrete retaining wall behind our house - General Contractors Near Me - Concord, California

Our house sits on a steep hill above a creek. For years we were having multiple landslides & mudslides below the house, and every time it rained we lost sleep worrying about the stability of the house. Finally, we can stop worrying. AcuStruct built an incredible retaining wall with piers drilled into bedrock. We talked to several engineers and contractors who were skeptical that such a wall could even be built on such a steep hill with difficult access. Dan and his crew did an amazing job and they were hardworking, reliable, and pleasant to have at our property. Would absolutely recommend them! read more

Many years after my foundation was replaced, under my home, by these amazing technicians, It is still perfect!! No broken windows or doors... The home was 10 full inches out of level and now ( for years) is still perfectly level!! I saved an amazing amount of money dealing with them, and had their job approved by the City (With a final permit) thanks Dan and your family team !!!! read more

Dan and his crew built our retaining wall over a year ago and we still look at it and comment on how happy we are with it. Excellent communication throughout the construction process and great attention to detail! read more

These guys are amazing. In short if you hire anyone else for a complex foundation engineering project, you're probably making a mistake. They put 18 piers around our house, levelled the floors and replaced a lot of the foundation. It was obvious from day 1 that Dan, Rafael and the rest of the team know exactly what they are doing. They were extremely professional, courteous and considerate. Change management was straight forward and simple. As far as I can tell the engineering was executed perfectly. Other companies that quoted the job whined about how complicated it was. To AcuStruct it seemed another day at the office. The only negative thing I can think of is they are hard to get. Unsurprisingly they always seem to be busy. read more

Dan Yust, Rafael Rivera, Luis and their entire crew went above and beyond our expectations in the removal and rebuild of our huge failing retaining walls. Every aspect of the job was immaculate, smooth and on time. Small changes and issues that came up were resolved quickly, seamlessly, and professionally. We really couldn't have asked for a better job. Thank you! read more

I have a crew of three installing a retaining wall on my property after an uphill neighbor damaged my hillside by allowing his roof water to flood downill causing some soil slip. Their work has been meticulous and exact. Acustruct owns their own machinery and trucks. With their equipment they drilled out 10' deep holes for steel beams and fitted 4" thick lumber between the struts. they fitted the beams meticulously. The crew supervisor has worked for Dan yust the owner for almost 15yrs. IN my opinion you could not find a better company. Their work passed instpection with no holdups and I am delighted with the end result. read more

I don't want to write this. After many email msg, I don't trust Dan intends to finish it. He doesn't do what he said. He constantly gave reasons not to repair or blame me unreasonably. E.g. foundation cracks or settlement were found even if engineers recommended. I was very concerned my home's serious landslide and settlement issues. I spent about $20k for engineers for retaining wall, drainage plans and soil / house reports. Sump pump and generator installation cost $31000. After paying Dan about $180K in full, I realized Eloy didn't close large 3ft x 4 ft stone wall opening and concrete floor opened up by Acustruct. Dan sent me an email to contact him after generator work is done. He would look into finishing uncompleted job. He didn't keep his words and blame me for job alteration. The job was started in spring 2017 and wasn't completed until fall 2017. Here are the issues: 1. Dan told me the job has 10 years of warranty; however, he seemed to have difficulty to put 10 years warranty in the contract. After providing an evidence of insurance, the policy wasn't renewed after expiration. 2. Dan intentionally switched plan to City- He supposed to submit revised plan with sump pump detail requested by City. I asked for a copy. He promised he would send me and engineer a copy by email. After numerous requests and months on the job, I still hadn't received one. After multiple requests, he got mad and sent me a copy. I was stunned "the plan contained no sump pumps details". He wasted my $600 plan revision fees. After repeatedly asking Dan for sump pump details upon Building Dept. requests for months, I never saw one until 9/26/18. It showed he didn't submit it until 12/22/17 months after the drainline was installed in planter box. 3. Drain line issue - Because he didn't use original sump pump plan showing pipe installing outside planter box, 4" pipe is installed in the brick planter box. My gardner told me he can't plant due to 4" pipe is blocked in the planter. Dan blames me for asking alteration after the work is done. Not true. I have never seen sump pump detail and never approved the pipe in the planter box. If he used that sump pump plan, the pipe won't be in the planter. My fault? 4. Pipe leak - I have sent him half dozen of photos and emails explaining the leaking pipe. The water from fog on roof flowing into downsprouts has been leaking from the connection / joint from the top of bottom pipe and bottom of downsprouts. Not properly installed. I don't understand why he kept saying 3-4 times he didn't understand this or he never seen this before?? Just get here, see it and get it done... 5. Shocking discovery of cracked concrete foundation! I asked Eloy if there is cracked foundation. He replied no. Days later, I was walking to the rear yard and found out two large cracks on front and middle foundation. I informed Eloy soil engineer was coming to see it. He quickly patched the crack with motar, was ready to cover with gravel and landscaping fabrics. 2nd, Underpin was recommended by engineer. Sign of settlement near garage door was shown where rain water entered into separated siding. Also, 3 gas line and pipe leaks were repair. Dan was backing up Eloy and told me it's a waste of money to fix the cracks and underpin despite engineer advised to install steel plate. This cracked foundation has solved the mystery why numerous cracks around windows, patio door on the first floor and separated molding on the 2nd floor. I was advised by another contractor to make sure the foundation is waterproofed. Again each and every necessary work, it's very difficult and frustrated to get Dan agree to do it. read more

I could not have had a better experience with a contractor than I had with Dan Yust and his AcuStuct team. First of all, the quality of the work was simply excellent. Also, and in my opinion, almost of equal importance, both communication and their consistently staying on the job until completion were outstanding as well. And all of this was after getting a bid from two others with the AcuStruct bid being the most competitive. Regarding the quality, Dan's crew simply knew what they were doing. Ours was a large job (at least for us) in that it involved replacing an interior garage wall that was up against a hillside along with replacing and expanding a large retaining wall and the entire driveway it supported. From the very large issues, such as lifting and holding the house up for the wall replacement, to the attention to small aesthetic details when doing the finishing work after the cement pours, all moved forward very professionally and their commitment to excellence was obvious. When we found a driveway that we thought looked particularly nice and that we wanted to emulate, Dan and his head man Rafael took the drive with me to look at it in order to insure we got exactly what we were looking for. That going that extra mile was appreciated. As far as communication was concerned, I was kept up to speed on what the next moves would be and any questions I had were answered politely with clear explanations of the process even if they were asked only out of curiosity. Although I tried not to interrupt too much, Rafael and Jose, who were managing the job daily, always stopped in order to keep communication very open. At the critical or big decision times, Dan was always there to make sure things were going well and to explain all options if there were any choices to be made. That same communication helped with their dealing with the engineer and all inspectors. The crew was there daily with few interruptions. If another job required a lot of manpower for a cement pour at that job site, I was informed in advance and the next day they were back on the job. And I benefitted from that larger crew being at my site when needed for a cement pour. In other words, absolutely none of the business of simply not showing up one day or no returned phone calls that I've dealt with working with other contractors in the past. Clean-up occurred daily, every attempt was made to accommodate traffic during the cement pour days and our neighbors actually commented on how friendly the workers all were. Dan mentioned at several points that his goal was to be sure that I, as the client, was happy with the work. He accomplished is goal. I simply could not recommend Dan and his AcuStruct team more highly. read more

One of the reasons we chose AcuStruct was Dan Yust's engineering degree, which was reflected in his knowledgeable assessment of our problem. Other aspects of his professionalism were top notch. The bid we received from him was not the lowest, but we decided to go with him due to the above points (we thought the lowest bid was not covering certain issues/not reflected in their bid and therefore they were missing problems that needed to be addressed). Would give a 4.9 out of 5 stars, the one negative was that AcuStruct does not itemize billing to our insurance company's liking. This caused us some headache on our end, hopefully other prospective customers will make AcuStruct consider adopting a more detailed/itemized billing that insurance companies will take. Overall, the best contractor we've had to work with in the past few years. read more

I was talking with a coworker who was asking about foundation work today and went to look up AcuStruct to see if they were still around. Glad to see that they are! We had our foundation work done in 2004 by Acustruct. They came and inspected the house and did a complete measurement. They were more thorough than other companies we had contacted for bids. I cannot remember if they came in less expensive, but I remember being impressed with Dan and how much he described the process and made sure we had a good understanding of it. They installed 18 helical anchors around out house, leveled the house using the pressure jacks and installed hand jacks on the piers on the interior of the house. It has been 12 years and no movement at all. Our house was damp underneath when the work was first done, and with clay soil, it took approximately 3 years until small adjustments in the hand jacks on some of the piers in the interior stopped needing to be done. We repaired interior cracks and they have not come back. We have had several average earthquakes (3.5-5.0) since the work was done and the anchors absorb the shock pretty well. The house swayed more than shook during those earthquakes, and there was no damage or new cracks on the inside or outside. Back in 2004 the company was in its infancy when they did the work on our house. Dan was very informative and described the entire process before and as it went along. The crew made sure that site was as tidy as a construction site could get when they were done for the day or weekends. We have recommended this company to friends over the years. read more

We live in the Oakland Hills and learned that lateral tiebacks and a sister wall were the solution to degrading soil on a descending slope behind our home. The AcuStruct team did an amazing job with this project. They were professional, timely, courteous and respectful to wear masks (For COVID-19 safety) at all times. They also took care to meet or exceed the soil engineers specifications where it made sense to. As homeowners who sought to protect our foundation and our home investment, they treated the project as if it was their own home, minding the details, and making the job look "easy" when it clearly wasn't. Can't thank Angel (foreman), Rafael (superintendent), Jose, Iran (sp'), Eloy (sp), Dan (the owner), and the other crew members enough for the great work. We have much greater peace of mind now that the work has been completed. They also stayed within their quoted bid. We cannot recommend them enough! read more

If anyone needs a great foundation/slab contractor Acustruct Structural Construction from Concord is the one. We've had serious cracked slab and unleveled foundation due to the drainage issue. I went through nightmares and fear of unknown for 4 years. I did research, looked for recommendation, received estimates and various procedures that blew my mind. I was drowning in an unknown territory and didn't know who to believe and trust. I found Dave Olnes, Civil and Soil Engineer in my neighborhood email. Dave is excellent in his field and very reasonable. He referred me to Dan Yust, owner of the Acustruct. I felt very comfortable with Dan from the start. He was very knowledgeable, patiently answered all our questions, any time of the day and never pressured us with sales pitches. Really down to earth. He was truly there for us all the way. He went above and beyond trying to find ways to keep the work within our budget. Dan kept us informed and if there were any changes in the plan he would include us in the decisions. We made the right choice of choosing Acutruct Co. for our project. Can't say enough about Rafael, their superintendent. Rafael made sure that the work was pretty much on schedule. He had excellent customer service and took pride in his work. He took the time to answer any questions we had and educated us. If Dan was not available Rafael would be the person to go to. Rafael kept close contact with Dan throughout the project. Enjoyed working with him. I have to give recognition to both foremen, Lido and Rene (sp?). They were outstanding workers who put forth the effort to complete the projects. Everyone knows that the crews are what makes the business. I cannot express enough on how amazing the crews were. They worked diligently with very few interruptions. There were crews of 3 to 5 men who worked efficiently and exceeded our expectation. We stayed in my house during the project. They covered the area with plastic so the dust would not be an issue for us. They made pathway with boards for safe access for us to go in and out. The crew left the sight immaculately everyday and made sure that there were no hazardous area exposed for the safety of the owners. I was totally amazed! Overall, they are a five star company!!! I've never seen this type of professionalism. I trusted them whole hardily. read more

This summer Dan Yust of Acustruct and his team did some major foundation work on our home. Scope of the project: 1) underpin 50% of the foundation to stop some very gradual settling 2) partial lift of the house to correct some noticeable sloping and 3) replace a 3 ft failing retaining wall with a much taller (8') retaining wall reinforced with rebar 4) replace rear perimeter foundation. I spoke to 4 other contractors and Dan was by far the most knowledgeable and had the best bedside manner. His bid was in the middle but he clearly was the best fit for the job - he and his team specialize in foundation replacement and underpinning. I found out about Acustruct through several other homeowners here in Trestle Glen who had similar work done and raved about their experience, and mine was no exception. Every case is unique, but according to the soils expert I consulted the homes in Trestle Glen are affected by a clay topsoil that in prone to not so gradual movement. Acustruct has perfected a method to stop the settling of a foundation by installing "pipe piles". The team digs out multiple trenches in the perimeter foundation, drives 20-25 ft steel pipes into the bottom of each trench, and then fills each trench with concrete. The combination of a dozen concrete cubes and the pipes make ensures the house will stop sinking. In terms of correcting the sloping, we were really pleased the team was able to lift our living room 6 inches (we were expecting only 4) and our dining room 2-3 in by using a series of hydraulic jacks. The lift was done very gradually but took only about a day and a half. Amazingly, the team accomplished this without disturbing our 40 ft high brick chimney. Dan and his foreman, Rafael, were professional, communicative and proactive (without being salesly) throughout. All 3 projects were done on time, on time, and we're super pleased with how everything turned out. The team also poured a new concrete driveway, a new patio in our garden, and built a wooden walkway up from the new patio to our 1st level existing garden deck. Couldn't have been happier and highly recommend. FYI - Dan usually works with Dave Olnes, a structural engineer who specializes in foundations. If you need to have similar work done, call Dave first to get the process rolling. read more

I hired AcuStruct to drill 3 holes 21' deep. It was in a tight spot with overhead wires so the job required a portable drilling rig. They were really busy but they were able to send a team out within a few days. Kevin and Emiliano came out, showed up on time, and were quick and efficient with their work. They are clearly experienced with the equipment. The holes were drilled perfectly and the project came in under budget. I highly recommend AcuStrut for your drilling needs. read more

Work performed was: repairing and replacing parts of my house foundation as needed; drilling and pouring external and internal concrete columns/piers; lifting/jacking and leveling the foundation; and then tying the foundation into the new piers. My experience with AcuStruct and owner Dan Yust was absolutely excellent in all respects. Dan is a consummate professional who cares most of all about giving his clients exactly what they need and doing the job exactly right from day 1 until completion. Before going to contract with AcuStruct, I had engaged a civil/soils/structural engineer for problem diagnosis and solution planning. At the planning/bidding stage, using the engineer's specifications for scoping and planning, Dan was very clear, both verbally and in writing, about exactly what he was proposing to do, how he was going to do it, the estimated time for getting it done, and the cost for doing it. Dan worked very closely and cooperatively with the engineer at all times during the project. Once I had accepted Dan's bid, he was more than reasonable during contract review and "negotiations". I put that word in quotes, because Dan basically accepted all of my suggested/requested contract modifications and new provisions. Dan was also totally honest about project scheduling, making it very clear to me that finishing his current clients' in-process projects had to have priority over beginning my job. Which, of course, is exactly as it should be; Dan then gave my project the same protection and priority once he had begun. AcuStruct owns all of their own heavy equipment - vehicles (a LOT of vehicles!!), compressors, soil drills, concrete pumping equipment, leveling and pressure regulating equipment, etc. etc. The AcuStruct crew conducted the project under the able supervision and management of Project Manager Rafael and day-to-day onsite supervisor David. Both of these individuals were highly professional, knowledgeable, and customer-service-oriented. Dan's workers are ALL employees of AcuStruct - he engages no casual day-to-day labor. During my project, two ancillary add-on projects were undertaken for which I believe Dan engaged the appropriate sub-contractors - one having to do with repairing a pre-existing (and previously unknown to me) problem in my HVAC system which came to light as Dan's crew were completing their excavation and demo phase, and one plumbing task which I had asked Dan to undertake as part of his job. Dan took full responsibility for engaging and managing these subs and for the quality of their labor and the materials they supplied. During the project, the need for 2 or 3 expanded scope change order items became apparent. These were things which could not have been observed nor foreseen before the job began. Dan's approach/pricing/timing for these change orders were MORE THAN FAIR!!! Quite a different approach than many contractors. Every day of the project, the AcuStruct crew took great pains to minimize inconvenience to me and to my neighbors. In fact, a number of my neighbors went out of their way to tell me how much they appreciated this and how impressed they were by it. The crew showed up every day on time, and often worked overtime and on weekends in order to keep the job progressing. The crew left the job site orderly and clean at the end of every day, with appropriate warning signs/tape and temporary barriers left in place to prevent any accidents. The results of the project were absolutely first-rate in all respects. The "symptoms" of the problem for which I had first engaged the engineer and Dan... buckling of hardwood floors and badly out-of-level living quarters - were all completely alleviated. All of my crumbling and failing foundation components were replaced/re-poured. Surrounding external soil and concrete pathways were properly replaced, tamped, and/or graded. All unavoidable damages to my home caused by the project (removed siding, external paint blemishes, doors and windows going out-of-plumb, etc.) were meticulously repaired by Dan's crew, and the crew left the property cleaner and more orderly than it was before they had arrived. In summary, AcuStruct performed very much above-and-beyond expectations in all respects on this very difficult and complex project, and I would unreservedly recommend them to anyone who has a need for these types of critical foundation improvements. I will be posting a version of this review on other appropriate websites. read more

AcuStruct is beyond excellent. Exceptional is more appropriate. They lifted, leveled and underpinned a cracked concrete slab under our cabana guest house with steel rebar and concrete piers. This righted a 7" downward slope in one of the bedrooms. They were professional in every detail of the job, from timeliness in being on the site daily until finish within the time frame estimated to cleaning up the site every day. They had to remove much of the flagstone patio and then replace the same when finished. You cannot tell that the flagstone had ever been removed. Great job with excellent communication from start to finish. read more

The 10 foot by 40 foot retaining wall between our house and our neighbor's house had to be repaired. It was about 80 years old and had some large cracks and deformations. Rather than starting from scratch, 25 foot long helical bolts drilled diagonally into the earth, along with a new curtain wall were used to re-enforce the existing retaining wall. The total cost was about 35K with permit fees and engineer drawings. We and our neighbor agreed to split the cost of the job and found a great geotechnical engineer to draw up plans for the wall. Our original contractor flaked out, so we asked our engineer for some new recommendations. AcuStruct was one of these contractors. Dan (the owner) and Dennis (the foreman) came over several times and provided detailed estimates for the several options proposed by the engineer. There estimates were significantly lower and more detailed than those of the other contractors. Dan and Dennis did a great job managing all the technical aspects of the job, and just as importantly, all the neighborhood issues, as well. Part of the work required access through a private road with cantankerous residents. Dan and Dennis were able to schedule the job to lessen the impact on everyone. Wear and tear on the private road was minimized and the work site was kept clean and organized. As the project proceeded, a third neighbor decided to do some additional, related retaining wall work, and Dan seamlessly worked this into the project. Dennis was on site almost much every day. He patiently answered all our questions, and explained the various decisions they were making. Their crew was extremely professional and helpful, and they were even able to hook up a conveyor belt to lift the excavated fill from below the wall into our back yard, so that we could level our previously sloping yard - a truly unexpected bonus. The finished wall looks great, and I'm certain it will stand longer than I will. AcuStruct did a fantastic job, and I whole enthusiastically recommend them ! read more

Work that needed to be done to our foundation: * Construct 16 piles in and around the house 15-18 ft. deep * Ten ft. foundation crack bolted and encased in cement * Level entire house 1-4 inches using pressure jacks * Aesthetic leveling inside the house using small hand jacks * Add a French drain to the front of the house Total cost of job was approximately $50,000 When we bought our house in August 2012, we knew we would need major foundation work done. My husband, a civil engineer, interviewed and got quotes from three local companies. AcuStruct came in lowest by a significant amount, and it was clear they were the most professional, doing the most detailed evaluation before giving us a quote. As a stay-at-home mom, I saw firsthand what work was done every day. The men showed up on time, worked extremely hard (were not on cellphones), never left before five, had a quick lunch, worked a couple of Saturdays to stay on schedule, and left the area as clean as they could. As they bored holes into the ground with a massive drill, they tried to keep damage to the exterior walls and hardwood floors to a minimum. The crew was conscious of my young children and kept the area as safe as possible. The whole team worked smart. Every day they would explain to me what the day's work would be. They were never condescending and explained their work in thorough and specific detail. They protected the house and tools from animals and rain. They were careful with our home and had the foresight to plan ahead so there was no extra effort to the work. Daniel, who worked on the job from start to finish was excellent at explaining the "what" and "why" of the job. He was courteous, easy to talk to and took my concerns seriously. He worked with me if there was a problem and took my concerns to his supervisor if needed. Dennis, the foreman of our job, was fantastic. He ran the job like a well-oiled machine. He was in complete control of his crew, there were never any delays, he took me around the house every day to explain what was happening, he tried to keep noise and dust to a minimum, he worked with me to keep us comfortable in the house when it was cold, he tried to keep damage to the house to a minimum by discussing options, and after the house was leveled, he personally went around and readjusted doors. He even offered to help me put up smoke detectors before the county inspector arrived. Dennis had a good balance between being personable and professional. The job finished on schedule and we paid the price that was quoted even though an extra reinforcement was added under the house for a particularly low spot. They even did little things as the job finished up like replant plants, saved some of the best dirt I requested for the kids, power sprayed the house, and basically left the exterior looking better than when they'd started the job. AcuStruct has spoiled us for other contractors. After having wonderful work done by them, I've had three other contractors work on the house. The other companies have treated me like I can't understand the work, have been uncommunicative, I've had to call them back to redo work, and I've seen the crews sitting around. I had one contractor not want to redo crooked work, one company left me in the dark as to what they were doing and I had to rely on the county inspector for information on the job. If I had to do it again, I'd hire AcuStruct in a second! read more

These guys are exceptional. I had a failing retaining wall that is holding up my driveway that had to be replaced, and Dan and his crew did an excellent job. They were recommended to me by the engineer who designed the wall, and they took care of everything - picked up the plans, dropped them at the County for review, kept on the County to approve the permit, picked up the permit, and then of course built the wall. They ran into a bit of an issue when drilling the holes for the soldier piles, as the soil was harder than anticipated, and quickly resolved the issue when they brought in heavier equipment, didn't miss a beat. The finished product is great - the piles are perfectly straight, and according to the engineer sunk to sufficient depth, the horizontal wood is placed perfectly, proper drainage rock was put in place, etc. I would highly recommend. read more

I live in Alameda, an island with historical houses built on unconsolidated soil over bay mud--kind of like the mission district in San Francisco--very susceptible to seismic movement. In other words, helical core anchors are needed where traditional footings don't work. By the time I reached out to AcuStruct to stabilize my chimney, the winter rains had started. Dan got me on his schedule for the next available window, which turned out to be longer than I hoped for, but waiting was the right thing to do. Who wants a job where there's a lot of starting then stopping for dewatering because you're too antsy to get it over with? Dan and I touched based frequently during the wet weather, with him managing my expectations and assuring me the work would get done as soon as possible. When the first window of good weather came along, the guys started the job and worked on it continuously until it was done, keeping the site clean and buttoned up at the end of each day. In the end, it passed the building inspection with flying colors. Owning a home in the bay area is too expensive to risk the wrong kind of foundation. Working with Dan and his crew gave me the confidence and product I needed. I highly recommend AcuStruct. read more

AcuStruct is excellent. They installed piers , grade beams, and braced walls as well as installed a window and some new siding . All of their work was done professionally.The crew was great they communicated unforeseen issues that came up and they were able to solve problems quickly and efficiently. They left the job site clean when they were done and they were courteous and professional at all times. read more
