Is Your Current Barrier Effective?

Conditions of substrate

  • Appropriate compacted granular
  • Soil gas permeable
  • Density of soil
  • Is it resistant to microbial attack

Adhesion may not be permanent

  • Effective adhesion to concrete requires penetration. This is achieved with surface preparation.
  • Must be able to bond to wide selection of materials

Not durable for construction

  • Weak and easily punctured

CGSB STANDARD​

  • CAN/CGSB-51.34-M86. Do not use polyethylene in contact with grade.

  • PRECIDIUM™ ECS™ SOLVES YOUR SOIL GAS PROBLEM

    Lifetime

    • Barrier remains effective for the lifecycle of building.
    • ECS bonds to itself for easy renovation or expansion
    • Can be seamlessly repurposed or renovated

    Durable

    • Not damaged by construction traffic.
    • 20 yr track record in heavy industry with no substantial deterioration whether buried or exposed.

    Permanently Bonded

    • Permanent spray on seal & bond to footings, grade beams and to penetrations.
    • Spray on bond penetrates concrete
    • Wraps to itself around penetrations
    • Elastic performance characteristics creates a gasket

    Seamless

  • Forms seamless monolithic membrane from grade to grade
