ABSTRACT:
A method for creating a barrier to protect wood materials for house construction or wooden structures such as houses from humidity, moisture and/or biological attacks, such as wood decaying fungi and termites, is disclosed. The method is to treat wood itself or, preferably, the ground surface under the floor with a liquid containing a synthetic resin emulsion and an anti-fungal and wood-preservative agent and/or a pesticide such as termite-controlling agent, and further, a foaming agent. The barrier contains a selected copolymer of vinyl acetate and a polyurethane polymer.
