Topical sealers can be made from acrylic epoxy and polyurethane based materials. Perimeter foundation insulation is required in colder climates to reduce the heat loss from a slab on grade to the below grade foundation wall. Once the waterproofing membrane is laid drying out of the structural slab will mostly take. Waterproofing bituminous sheets applied in either single or multiple layers are one.

On completion of waterproofing membrane and before undertaking any further activity it shall be tested by plugging the outlets and flooding 50mm above the highest point by hose and leaving flooded for twenty four hours before draining off.
