Spray-applied dampproofing (tar) is the traditional method of protecting a foundation wall for both poured concrete and block masonry constructions that are approximately 10 ml thick.
Traditional dampproofing helps to stop water vapour from passing through a foundation wall into the basement area.
It is highly recommended when using this traditional method of dampproofing to install a drainage layer. Delta MS air gap drainage layer helps eliminate leaks and deters hydrostatic pressure.
Delta MS is a high density polyethylene air gap membrane, in new construction it is typically used on the exterior of the foundation wall going down to the footing to protect your basement from hydrostatic pressure and deter water entry.
Delta FL is a high density polyethylene sheet membrane with a dimpled surface, installing it with the dimples down to create an air space above or below the slab. Once the Delta FL is on the entire floor the plywood is then installed, fastened and secure to ensure soundness before installing your finish flooring: carpet, tile, hardwood, etc.
Delta FL is recommended for both new construction as well as retrofits. The Delta FL eliminate the cold damp feeling in your basement area, in exchange allows you to utilize you basement as additional, comfortable living space.
