BridgeDECK CorrosionBLOK™
Designed to Work with ETT-Based Systems
With a single application, ETT remains within the concrete matrix — delivering protection from within for the life of the concrete.
ETT penetrates into cured concrete and, when activated with water, develops an insoluble gel within the concrete itself—forming a subsurface membrane that helps protect against water and chemical intrusion for the long term.
Works Within The Concrete
Unlike surface-applied coatings, ETT becomes part of the concrete, helping protect from within.
