Is the plastic waffle sheeting used in Basement System's ThermalDry installations available independently as a retail product? Or, are there alternative products to float a floor over a concrete slab with several slight damp spots (short of putting down a wood framed sleeper system) that allows air circulation?

What is it you are trying to do? Your post is a bit confusing. Please elaborate.

sure. i have recently had to reinforce the foundation of our 20's house to support new construction. in doing so, we cut through the slab to add additional footings. now the joints between the old and new concrete pours are damp. there is never standing water, just surface dampness from normal soil moisture. basementsystems distributes (to its dealers as far as i can tell) a product line, thermaldry, for floating a plywood subfloor over a slab in these situations. the product i'm after is the plastic sheeting that serves as the barrier and standoff for the floated floor. the sheeting is a heavy plastic with a waffle profile that gives it a 3/8" thickness, but most of that height is airspace for circulation. a plywood subfloor is anchored to the slab capturing the plastic sheeting and raising the floor ~7/8". a 1/4" gap is left along the walls to allow air exchange. i would like to do the installation myself, but need to find the plastic sheeting, or an equivalent product.
