What is ExpandoThane?

Our ExpandoThane product is an expanding polyurea waterproofing compound. Our material contains micro blowing agents that create a tough and flexible waterproofing membrane capable of expanding 5 to 7 times its volume. This amazing formula allows for a barrier between the outside and the interior of a foundation wall or applied as a roof coating that completely eliminates the water from finding a way in. Standard polyurea will not fill the gaps in between crevices, or bug holes, because it was designed to mimic the contours of the object being sprayed. However the ExpandoThane material will expand in those holes and crevices 5-7 times the volume. Its' high elongation and tear strength give it incredible performance, bridging seams and expansion joints. ExpandoThane comes in either the cartridge material canisters or by the gallon, in different quantities.
