BARRIERS TO PEST INVASION

摘要

Barrier devices against pest invasion are provided that allow sealing around a utility penetration(8),for example a pipe or conduit.In one embodiment,the barrier device is a barrier boot(2)that is sealed to a foundation slab(50),in order to prevent pest invasion through the spaces(52)formed between the foundation slab(50)and the utility penetration(8).In another embodiment,the device forms a continuous barrier with a surface receiving the utility penetration,for example a sheet−type barrier,a building foundation,footer or wall.In yet another embodiment,the device is a stand alone product which provides protection when embedded in concrete.
