BridgeDECK Protectant Plus

Alchemco BridgeDECK PROtectant PLUS is an enzymemodified subsurface membrane waterproofing system. Spray apply PROtectant PLUS to form a barrier, protecting your infrastructure from water and contaminants like chloride ions. PROtectant PLUS penetrates the concrete and reacts to create a flexible, subsurface membrane that fi ls cracks and pores. Designed to handle thermal stress, it seals existing cracks up to 1.5 mm and protects against future cracks up to 0.3 mm.

HOW ETT WORKS

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.

    • Unlike surface-applied coatings, ETT becomes part of the concrete, helping protect from within.

    • Fast, practical application with protection designed to remain inside the concrete.

    • A responsible solution for projects that demand durability and safer chemistry.

  • Extending the service life of concrete helps reduce repairs, replacement cycles, and material waste.
