ELIMINATOR® is a high performance waterproofing membrane for the protection of concrete and steel bridge decks based on Stirling Lloyd, now GCP’s unique ESSELAC® advanced resin technology and extensive experience in the development of coatings for specialist waterproofing. It cures rapidly to provide a tough, flexible seamless membrane impervious to water and waterborne contaminants. ELIMINATOR® has an unparalleled track record with thousands of structures waterproofed successfully throughout the world.
ELIMINATOR® protects concrete and steel structures from the corrosive effects of water and chloride ions. Typical applications include:
- Concrete Bridge Decks
- Steel Bridge Decks
- Bridge Piers
- Bridge Service Ducts
ELIMINATOR® is installed in conjunction with Stirling Lloyd, now GCP Applied Technologies, proprietary primers, ensuring a high bond between substrate and membrane. For highway bridges a range of compatible tack coats promote adhesion between membrane and surfacing. The membrane can be trafficked for limited durations when required. Please discuss with GCP Technical Services if considering this application.
The system can be adapted to accommodate both high and low ambient temperatures without any detriment to the performance of the system (See table below).
- Long and effective life
- Able to withstand high humidity and cures rapidly even at low temperatures enabling all year round application
- Rapid application and re-access
- Crack-bridging across wide temperature range
- Excellent abrasion and chemical resistance
- High bond to substrate, preventing tracking of water under membrane.
- High thixotropy for application to vertical and horizontal surfaces
- Seamless, and chemically bonds to itself
- Two color-coded coats assure highest quality system minimizing defects
- Withstands 480°F pavement placement on the cured membrane
- Tough – tolerant to direct ballast loading without protection board. Conforms to AREMA Specifications Chapter 29-2-6, 2.3.10
- Quality Assured – ISO9001 certified manufacturing location
- Applied only by authorized and trained contractors
The substrate must be primed with an appropriate GCP primer prior to application of the ELIMINATOR® membrane. A choice of primers are available depending on the type of substrate and weather conditions.
ELIMINATOR® is typically spray applied. The membrane is applied when the primer has cured, typically within 20 minutes. Two distinct color coats are used to aid quality assurance. ELIMINATOR® is typically applied in multiple configurations that includes, but is not limited to:
- One coat at minimum film thickness of 90 mils
- Two equal coats each at a minimum film thickness of 60 mils for a total of 120 mils
- Two coats comprising a first coat at a minimum film thickness of 80 mils followed by 40 mils with an aggregate broadcast
- Other configurations exist on a on project-by-project basis
Tack Coat/Bond Coat
A tack coat or bond coat must be applied to ELIMINATOR® when it is being used as a waterproofing membrane on road bridges underneath asphalt paving. A range of tack coats and bond coats are available depending upon the pavement specification1.
All tools and equipment should be cleaned with acetone before the material is allowed to cure.
ELIMINATOR® liquid resin components are classified as flammable liquid (flashpoint 52.7°F, 11.5°C) and must be handled accordingly. Workers should wear appropriate protective clothing. Adequate ventilation must be provided. Please refer to the most recent Safety Data Sheet (SDS) for recommendations.
Safety and Handling
Read and understand the product label and Safety Data Sheet (SDS) for each system component. All users should acquaint themselves with this information prior to working with the products and follow the precautionary statements.
SDSs can be obtained by contacting your local GCP representative or office, by calling GCP toll free at 1-866-333-3SBM (3726) and in some cases from our web site atgcpat.com.
Packaging & Storage
