I cannot find anyone who is qualified to do surface prep of a concrete floor to prepare for engineered floating cork floor.
I've gone thru 3 guys so far - the first one did a disastrous job with the self leveling, came back, chopped it up, tried to patch it, left a mess. The next guy came in with the 10" diamond grinder, got it somewhat flat but with lots of 1/4-3/8" dips. He came back to fix things up with patch leveler, made it worse, told me he would install flooring over the floor the way it is, stopped returning my calls. 3rd guy came in with the self leveler over the whole floor and did an OK job. But there are a few spots that need to be knocked down and a few spots that need to be filled in.
I need someone qualified to grind down the few remaining high spots and patch the low spots and get it flat within tolerances (1/8" over 10', but I would settle for close enough at this point). It's an older house with a low basement ceiling so I can't pour self-leveling concrete any more. Not a really big space either, about 350 sq. feet. I feel like I am getting the wrong guys by getting concrete/masonry people but none of the flooring guys I have called do this kind of work. Tried calling Lumber Liquidators and they gave me their installation contractors and they didn't do it either.
If anyone has a recommendation it would be greatly appreciated. In Long Island, south shore eastern Nassau.
It was not cheap but came out amazing...I think the company he used was nation wide...I sent a text to him for the name...when he texts back I will pass it on...
You could absolutely set and engineered floor on their finished product...and I think he had a 20 year guarantee on all cracks/floor etc
