Application

  • For use in horizontal, vertical or stepped damp-proof courses.
  • Suitable for unsupported cavity trays for sealing cavities to deflect downward movement of water in external cavity walls with masonry inner or outer leaves and timber frame construction.
  • Engineered for durability and flexibility to allow site forming for built in or face fix applications to residential and commercial construction types.
  • Designed to prevent moisture and radon gas ingress, providing a robust barrier allowing continuity with membranes offering whole footprint coverage.

Description

Flexiload high performance damp proof course is an innovative, BBA Approved, bitumen-free damp-proof course (DPC) that combines the latest polymer technology to surpass traditional British Standard DPCs as a horizontal, vertical or stepped damp proof course.

Suitable for unsupported cavity trays for sealing cavities to deflect downward movement of water in external cavity walls with masonry inner or outer leaves and timber frame construction.

Engineered for durability and flexibility to allow site forming for built in or face fix applications to residential and commercial construction types.

Designed to prevent moisture and radon gas ingress, providing a robust barrier allowing continuity with membranes offering whole footprint coverage.

Feature and benefits:

  • BBA Certified for all applications including unsupported cavity trays.
  • Elastomeric polymer composition: contains no hazardous pitch or bitumen, providing a safe, modern solution.
  • Cavity tray system: robust not to require support along its length.
  • Load resistance: withstands high compressive forces, ensuring no extrusion under load.
  • Puncture and tear resistance: high durability even in demanding environments.
  • Flexible jointing options: joints can be securely taped or welded for watertight installation.
  • Embossed for adhesion: surface texture increases adhesion, reducing slippage.
  • Cold weather flexibility: remains flexible at low temperatures.
  • Range of widths: available in various standard widths for versatile installation.
  • CE Marked: certified to BS EN 14909 standards for reliable performance.
  • Radon resistant: acts as a radon-resistant barrier.
