I wanted the 600 sq ft crawl space concrete pad sealed over with a poly liner but the pad is divided in half by a 6" concrete base for a 2x4 supporting wall. I was assured that sealing the poly liner against the little concrete wall was not an issue. The liners were laid down. One half was ok, loose but ok. The other side was laid well for part of it but then about 1/2 way down it twists and starts to bunch up. Adhesive used to seal the poly liner to the concrete base for the supporting wall failed after 2 weeks thus defeating the whole purpose of having a sealed off floor. For 2 1/2 months now, I have tried to address this issue with the owner by emailing and calling. He has not bothered to respond. I am not impressed by the workmanship nor the integrity of this Kelowna company. read more
