I'm installing Dricore subfloor in my 800 sq.f. basement. So far everything is good. 60% done. My floor is relatively leveled except 1 single place where floor drain is located.
The area around floor drain (about 2 feet radius) is slopping down about 1.5 inch. So I have to use a lot of Dricore shims. At some point almost whole package to keep floor leveled.
I stopped the installation as it seems wrong to put that amount of leveling shims. They are still bouncing. + Cost of shims kills the whole deal on floor.
So I'm looking for some alternative to these expensive shims. Some king of plastic board which I can cut and put like support under Dricore boards.
Is there anyone who had similar problem ans solved it?
Thanks everybody, and looking forward for answers.
I have used strips of asphalt shingles to level basements subfloors. They are waterproof and are easy to stack and layer.
Good idea. I did not coume out to this one and instead used concrete to rise drain slope. It still correct as I tried bucket of water to test the result. I had to use 3 bags of concrete.
Any ways I have finished everything long ago. But your advise with shingles is very helpfull as I see now that I would go with it.
Hopefully this helps someone in future.
