Cu-Lam Barriers

Barrier wraps are impermeable membranes that are placed over the butt end of wood poles just prior to installation. Barrier wraps offer additional protection to treated wood from decay, insect attack, and preservative strength loss over time. They also protect the surrounding soil from preservative migration.

Independent tests have proven that the use of one-piece barrier wraps can significantly reduce the occurrence of decay and insect attack on treated wood structures when the ground contact portion of the wooden member is protected from soil contact by the barrier. For example, preservative treated stakes wrapped with a barrier in a Hilo, Hawaii have out-performed un-wrapped stakes 2 to 1. Basidiomycota vector-function is suppressed by impermeable membrane barriers; preventing these decay fungi from efficiently translocating soil-source inorganic nutrients

They extend preservative service life and keep the original pressure treatment in the wood where it belongs.
