ELIMINATOR® bridge deck waterproofing membrane

Extending the life of road and railway bridges

Overview

Superior protection for bridge decks

Steel and concrete bridges are vulnerable to attack by water, chloride and frost, leading to deterioration and even structural failures. Installing a high-performance waterproofing membrane is therefore an essential part of any bridge construction or refurbishment program. The ELIMINATOR® bridge deck waterproofing membrane is a cold, spray-applied solution that can outlast the life of the structure — reducing maintenance costs and traffic disruptions.

Achieve long-term performance 

ELIMINATOR® has an unmatched global track record, protecting thousands of concrete and steel bridges from water ingress and corrosion. Powered by advanced ESSELAC® resin technology, the system forms a fully bonded composite between the deck, membrane, and asphalt surfacing. This high-strength bond resists extreme climates and heavy traffic loads—ensuring long-lasting structural integrity and performance.

Accelerating waterproofing application

ELIMINATOR® is engineered for application speed and reliability in all climates. Unlike moisture-sensitive alternatives, it can be applied year-round—even in high humidity or freezing temperatures—without compromising performance. The membrane cures in under an hour and features a two-color application system for instant visual quality control, helping crews verify coverage and minimize delays on site.

Product advantages

  • Seamless, flexible membrane with excellent crack-bridging and chemical resistance
  • High bond strength to concrete and steel—prevents water ingress and delamination
  • Rapid cure and re-access, even in low temperatures, for all-season application
  • Two-color application system for built-in quality assurance

SA1030 Bond Coat Data Sheet

Waterproofing accessories

Description

SA1030 Bond Coat is a polymer-modified bond coat designed to create a strong, durable bond between the ELIMINATOR® waterproofing membrane and hot bituminous surfacing. It is especially effective where the bitumen content is low or the surfacing layer is thin, ensuring reliable adhesion and long-term performance.

Key Benefits
  • Provides a high-strength bond between waterproofing membrane and asphalt surfacing
  • Rapid solidification allows for quick progression to surfacing
  • Effective even with thin or low bitumen surfacing layers
Application Type
  • Applied directly to cured ELIMINATOR® membrane using standard methods
