ELIMINATOR® bridge deck waterproofing solution

Extending the life of road and railway bridges

Superior protection for bridge decks

Bridges are vulnerable, subject to attack by water, chloride and frost, leading to deterioration and issues with structural integrity. The installation of an effective waterproofing membrane is therefore an essential part of any bridge building or refurbishment program. The ELIMINATOR® waterproofing system is a cold, spray-applied solution that can outlast the life of the structure — reducing future maintenance and associated costs and traffic disruptions.

What is the ELIMINATOR® waterproofing system?

The ELIMINATOR® system is a high performance waterproofing membrane based on unique ESSELAC® advanced resin technology. Developed for the protection of concrete and steel bridge decks, the ELIMINATOR® system has an unparalleled track record with thousands of structures waterproofed successfully throughout the world. The system features a range of innovative primers and bond coats that help to create composite action between the deck, waterproof membrane and substrate, ensuring that the membrane is fully bonded both downwards to the deck and upwards to the surfacing.

This durable, rapid-cure system forms a flexible, chemical resistant, and seamless waterproof membrane with no vulnerable joints to deliver a watertight solution.


The world’s first cold, spray applied bridge deck waterproofing system, the ELIMINATOR® product revolutionized the waterproofing industry. Airless spray equipment has been specifically developed to dispense, mix and apply the product to offer fast, simple and effective sealing, even on complex detailing. Outputs can reach in excess of 2,000m2 per day, meaning less time spent onsite. The ELIMINATOR® waterproofing system’s fast cure means that other trades can access the site one hour after application, assisting contract progression. Applied in two separate color-coded coats aids onsite quality assurance, ensuring a seamless and protective waterproof barrier is achieved. Application can be commenced in a range of climates. The ELIMINATOR® system cures rapidly in high humidity or low temperatures, allowing global application all year round.
