The crew of two polite and well spoken young men showed up on time and explained the process well. Although I was skeptical about how much could actually be accomplished with a section of the pool decking which was cracked and was at least one inch higher than the adjacent section along the expansion joint, the result was excellent. Both pads are now the same level all along the expansion joint. The crew cleaned up after themselves, and other than the newly leveled concrete, they left no signs that they had been there. Thanks Kris.
