TESI S.p.A. presents its new splash zone coating ENVIRAWRAP

The marine environment is known as a harsh and extremely corrosive environment due to continuous contact with highly aerated sea water and the erosive effects of spray, waves and tidal actions, which destroy any protective film that might be formed on the piles’ surface.

In order to perform the best possible protection of marine infrastructures, TESI acquired the original ENVIRAWRAP brand from Strange Corrosion, LLC in 2023 and developed a new induced-tension polymer wrap, specifically designed to provide an easily installed retrofit encapsulation system for the cladding of vertical risers and piles in the splash zone.

ENVIRAWRAP’s unique features include easy and fast one-piece installation: no multi-layer or multi-phase procedure is required, and few tools are needed. Long term integrity: the wrap’s elastic memory properties create an inward force when mechanically tensioned around the pile. This hoop tension force causes the organic corrosion inhibitor – factory blended into the thixotropic gel – to exude into the surface irregularities, providing both active and passive protection of the substrate. No ‘bare-metal’ preparation is required, only the removal of loose material and marine growth is needed. Easy substrate inspection: customers simply loosen bolts and partially open the one-piece wrap. After substrate inspection, users apply additional gel (if required) and reposition the wrap and tighten the bolts. The expected lifespan of the coating is over 20 years.
