In this one photo you can get a close up view at some of the products used. The grey plastic thing is the sub-flooring drainage system, WaterGuard, and the tape is actually WaterGaurd Sheeting. WaterGuard Sheeting is used over loose stones and the WaterGaurd drainage system before fresh concrete is poured. This is also a close view of the CleanSpace Wall Liner. This is the product that does the actual waterproofing.
