Recent Review: Their first job was to pour the basement slab in my new home. First, I live in an area that is known to have high levels of radon gas, so I put down a 6 mil plastic vapor barrier on top of the base course of gravel. Chamberlain Concrete then added rebar, tied it together and supported it with rebar chairs (supports). The rebar chairs were inappropriate for the application and had narrow feet, that when the crew stepped on them, punctured holes in the vapor barrier, everywhere. (There are rebar chairs available locally that clamp on the rebar and have about a 2" round disc that supports it on the ground. ) I then came in behind them, myself, and repaired all of the MANY holes in the vapor barrier with Duct tape. On the day of the pour, I asked the crew to not step on the rebar, as it caused the rebar chairs to puncture holes in the vapor barrier. They acknowledged my request and proceeded to step on every single piece of rebar they came across. Not only pushing the rebar to the bottom of the slab, but also puncturing holes in the vapor barrier. Awesome. On the first test, my radon level was 200 times the EPA recommended level. Now that's professionalism. About 6 weeks later, it was time to pour the floor of my garage. They were scheduled to pour on a Wednesday, and I traveled into town on Tuesday night to be present for the pour. When I landed and turned on my phone, I got a voice mail saying they had to cancel and reschedule for Friday. I was unable to stay for Friday as I had to be at work, 300 miles away. The description I then got of the day of the pour came from my framing contractor. He relayed that all of the concrete was delivered at once, for what is a 2,000 sq ft garage floor. (4 car garage + a mud room). Some of the concrete sat for a couple hours in a heap while they worked concrete in other areas of the garage. When it was all done, I had large cracks and heaving fault lines in one stall and the mud room. Absolutely horrible. I was sucker enough to allow them back to complete my driveway and sidewalks a couple months later. Fortunately for me they stood me up twice more and I never called them back. I had another concrete contractor finish the job, who did excellent work. That gave me even more remorse for not using them in the first place. Avoid Chamberlain Concrete and Jensen Concrete and Construction if at all possible.
