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 programme. The ELIMINATOR® waterproofing system is a pioneering cold, spray-applied solution that can outlast the life of the structure - reducing future maintenance and associated costs and traffic disruptions.

- Description
- Key Benefits
- Applications Type
ELIMINATOR Waterproofing Membrane is a GCP Applied Technologies (“GCP”) high performance system for the protection of concrete and steel decks. ELIMINATOR Membrane is based on GCP’s (formerly Stirling Lloyd’s), unique ESSELAC advanced resin technology and extensive experience in the development of coatings for specialist waterproofing. ELIMINATOR Membrane cures rapidly to provide a tough, flexible seamless coating and has an unparalleled track record with thousands of structures waterproofed successfully throughout the world.
- Single source system. High performance GCP (formerly Stirling Lloyd) proprietary primers and tack coats promote secure adhesion between substrate and surfacings on highway bridges, piers and other critical highway components
- ELIMINATOR Membrane can be applied at temperatures between -10ºC and + 50ºC without any loss in performance.
- Unparalleled track record of success
- Concrete Bridge Decks
- Steel Bridge Decks
- Bridge Piers
PA1 PRIMER is a single-component, air drying primer for concrete and cement screeds, enabling application in temperatures as high as 50°C. PA1 PRIMER is based on GCP Applied Technologies’ advanced resin technology and extensive experience in the development of high performance primers.
PA1 PRIMER is used to seal the surface of concrete screeds and to improve the adhesion of GCP’s wide range of membranes, screeds and coatings.
Approved for use with the Eliminator bridge deck waterproofing membrane by:
- EOTA – ETA No.15/0362, Liquid Applied Bridge Deck Waterproofing, ETAG 033
- British Board of Agreement (UK) - HAPAS Certificates No.11/H169, 11/H170, for Highways England road bridges.
PA1 PRIMER is used to seal the surface of concrete screeds and to improve the adhesion of GCP’s wide range of membranes, screeds and coatings.
ZED S94 is a single-component, anti-corrosive air-drying metal primer. A hand application grade is supplied as standard.
Application should take place within three hours of grit blasting the substrate. The substrate must be clean and dry.
Apply evenly to the substrate by brush or roller.
Do not allow the primer to ‘pond’ or ‘pool’. One application of ZED S94 is usually sufficient. Overcoating with Eliminator or other products is recommended to take place as soon as possible in order to minimise the risk of contamination.
What is 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 which 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.
Application
The world’s first cold, spray applied bridge deck waterproofing system, ELIMINATOR® revolutionised the waterproofing industry. Airless spray equipment has been specifically developed to meter, 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 on site. The ELIMINATOR® waterproofing system’s fast cure means that other trades can access 1 hour after application, assisting contract progression. Applied in two separate colour-coded coats aids on-site quality assurance, ensuring a seamless and protective waterproof barrier is achieved. Application can be commenced in a range of climates, ELIMINATOR® cures rapidly in high humidity or low temperatures, allowing global application all year round.
Product Advantages
- Fast application with industry standard equipment, no need for hot trades
- Requires minimal surface preparation
- Provides effective sealing of complex, critical details and penetrations
- Onsite quality control, ensuring the integrity of the membrane prior to surfacing
- No critical overcoating time allows phasing of work, enabling greater scheduling flexibility
- Unaffected by application of surfacing up to 250°C
- Long lasting and highly durable, protecting the structure for the long term
