We recently landscaped our driveway in late 2018 with a local Boulder contractor (Prana Construction). The contractor uses Robles Bro's. As their concrete subcontractor. Robles added a whole new section to the driveway, alongside the existing concrete that has been there 15+ years.
Within less than a year, the Robles concrete began to erode, crack and crumble badly. However the existing concrete driveway remained in great condition. The contractor and a Robles tried to explain it away by saying we were using chemicals on the driveway for snow melt that eroded the concrete , however the original concrete was quality and unharmed after 15 years and remained so. And even in areas of the driveway where we never use any snow melt, the concrete was degrading fast. Upon sending videos to both our contractor and Robles, the answer we got was that the concrete is only guaranteed for a year and we have no Options for fixing it. Not what we wanted to hear after spending $12,000+. So I'm sharing this review to warn anyone else clear away from using Robles Bros and making the same mistake we did. Check carefully who your contractor is using if you are not engaging the concrete sub yourselves. I am including photos of the awful quality concrete here and if it works I'll also post a video. As of writing this review, both Robles and Prana have elected to ignore the issue and not attempt to fix or remedy the situation. Pretty devastating given the amount of money invested. read more
