Lab's crews did a great job on a concrete patio and walkways in my backyard. The project area @ 1080 sq ft and only took 2 days to complete. The project consist of drilling and inserting iron rods into the house's foundation, laying down iron rods inside the wood frames, laying down sands inside the wood frames, and wheel barreled in the concrete. After the job, the crews cleanup the work area neatly and remove the wood frames (after the concrete died up) as promised. There was a long hairline crack in the concrete just days after. JR promised to come back to look at the crack and he kept his word and came back to fix it. I will definitely recommend JR and his crews due to their professionalism and competitive pricing. Thank you JR and crews.
