Laminate over uneven basement floor


Hi All,

I'm renovating my basement, and this is the first time that I've ever done any flooring.

I have a laminate that I am planning to lay down over a subfloor of the dimpled foundation wrap used for waterproofing.

The pad in my basement is not as level as it could be. I have already used leveling compound, quite a bit of it, actually, but it's a fairly large and open area and even in doing that I was unable to get a perfect level throughout.

What can I do to bridge the remaining low points? I've read about using asphalt shingles for shimming, and wonder if that could be an option? If so, what is my best method? I was planning on laying the floor right over the wrap, but is it feasible to use shingles over the membrane, to level a layer of osb and then the floor over that? Headroom is an issue, so definitely looking at as thin of a solution as possible.

Any help is greatly appreciated.

You need to make the floor flat before installing the membrane. A #50 of self leveling does about 50 sq. ft. @ ⅛" thick. You need lots of bags for a large area.

If you have only a few high spots, grind them down first. Fill all the low spots till all is flat. Self leveling needs help to flow and lots of planning to get it right. No shims or OSB. OSB isn't gonna make the floor flat, just higher.

At the worst, laminate will separate on an uneven floor and the best you could hope would be that it would be very noisy when you walk on it.

I agree, not a good idea, but we don't seem to have much luck talking people out of it.

Agree that laminate in a basement is a bad idea. Basements are subject to moisture for a number of reasons and laminate is subject to damage from moisture. The joints rippling, or just plain humps.

What is a better option. I have a lot of laminate available to me.

I'm not that big on tiling.

Allure is a much better choice than laminate in a basement, though. As a landlord, Allure is a great product. Reasonably priced, easy installation by the DIY-re, looks good, is easily replaced and/or repaired if it is damaged and is more pet proof than most other floorings of choice. I've laid in in several apartments in kitchens and baths with no problems. Have also replaced several sections that were damaged with no problems.

In a basement the Ultra is a better choice than the grip strip because excessive, persistent moisture through the floor can cause failure in the grip strip.

The subfloor (in this case the concrete) doesn't have to be "level", it does however have to be "plane". There's a difference. OSB over concrete isn't the answer, don't even go there. The shingles is also a bad idea, what will hold them in place? Laminate floors are floating floors and any up and down movement (from an out-of-plane subfloor) will cause the floor to self-destruct at the seams, if the moisture doesn't get to it first.
