Looking for some advice...
We've done self leveler before. We've done in floor heating before. We've done LVP before. Never all together in a basement though.
We're currently renovating a basement apartment and decided to go with in floor heating as a primary heat source. Big regrets.
We bought Amdry Thermoquiet to decouple from the concrete floor and fastened it down with carpet tape. We then attached the in floor heating coil with the tracks and hot glue. All good. We sealed all the edges and boundaries we needed to and went on to pour self leveler. It went down smooth and the house smelled like concrete. All good. We went down the next day to find hollow spots where the concrete separated from the underlayment and as soon as these sections were stepped on, they cracked and crumbled.
We now have high and low spots with cable buried in the majority of the self leveler. We're debating pulling up the entire thing and scrapping it or trying to patch the areas that were bad. Any advice? We've sunk over $1500 in it already.
