Level a basement floor

jimbo22sOctober 26, 2009

I need to level a small depression in the basement floor in order to install laminate. I would rather not work with self-leveling concrete for the little bit I need. Sand would level the small area except that it will absorb moisture, but what about a few cups of lanscape paver base under the poly sheeting? The leveling base is fine granules of rock commonly used under a stone or paver brick installation.

A bit of sand will be the least of your problems if you're just planning to put vapour barrier on the floor, followed by laminate.

Building Science Corp. recommends at least 1 inch of XPS followed by two layers of 1/2" plywood and then the laminate.

I guess I misunderstood this sentence from "Understanding Basements":

"A sheet polyethylene vapor barrier should be located over the rigid insulation and in direct contact with the concrete slab."

I saw "over", "direct contact" and "concrete slab" and understood that to mean that the barrier should go on top of the concrete, as many would recommend. I read it more closely and see that it recommends to avoid an interior vapor barrier.

What is the best way to install the laminate if I am not in a position to install 1" of XPS and two 1/2" layers of plywood? It sounds like there is no ideal way but I would like to know which method is least likely to cause an issue.

Thank you.
