Abstract: A method is disclosed to treat a termite infestation on building, where that building comprises a structure and a foundation, where the foundation comprises an exposed portion in contact with soil and extending upwardly to the structure, and wherein one or more termite tunnels are disposed on that exposed portion. The method removes any existing termite tunnels from the exposed portion of the foundation. The method further disposes a polymeric material horizontally on the exposed portion of the foundation, and over any former termite tunnel locations, where that polymeric material does not comprise a cloth tape or a cloth tape comprising a polyurethane coating.
