We had a leveling company come in to level a couple of PCs of concrete around our pool. This was supposed to be a simple job. They made a mistake on one section and raised the concrete over an 1” above the copping side which goes up to Flag Stone. In stead of stopping, after one section seeing the damage, they went all the way down the side, leaving a dangerous sharp edge. (About 20+ ft) We now have to remove all of the stone and mortar and have it reset HOW do we keep all of the debris out of the pool. They will have to work from the top.
