  • Product Name
  • Description
  • Key Benefits
  • Applications Type

INTEGRITANK® is a high performance, structural waterproofing membrane for the protection of steel and concrete structures based on GCP’s (previously Stirling Lloyd) unique ESSELAC® advanced resin technology and extensive experience in the development of coatings for specialist waterproofing.

Key Benefits
  • Unaffected by high humidity 
  • Rapid cure even at low temperatures 
  • Able to carry load or traffic after one hour
Application Type

Gain continuous waterproofing protection

Structures such as decks and balconies are continually exposed to the elements, making them susceptible to corrosion and water ingress. Therefore, it is crucial that a protective coating is applied in order to maintain their integrity. Developed by Stirling Lloyd (now GCP Applied Technologies), the INTEGRITANK® waterproofing system offers high bond strength in addition to crack bridging that helps these structures stands the test of time. 

Accelerate return-to-service

Unlike sheet-applied waterproofing, which can be time-consuming to apply, the INTEGRITANK® liquid membrane can follow any contour or irregular surface, making simple work of complex detailing. The system’s fast application, one-hour cure time and on-the-spot quality assurance mean less time is needed for waterproofing application.

Additional Product Advantages:

  • Flexibility to apply by hand or spray
  • Can be applied virtually year-round in a wide range of temperatures
  • Eliminates the need for complex equipment and hot works permits
  • UV and chemical resistant 
  • No protection boards or root barrier required


  • Green roofs
  • Basement roofs
  • Terraces and balconies
  • Podium decks
  • Immersed tube tunnels
  • Cut and cover tunnels 
  • Bored tunnels and shafts
