Foundation Radon Barrier Systems

Explore barrier continuity as one part of a professionally designed radon strategy for foundations and below-grade construction.

UNDERSTAND THE SYSTEM

What goes into it.

A radon barrier is a specialized part of a building design. Continuity at foundations, service penetrations and wall junctions matters, alongside testing and the wider mitigation strategy.

  1. 01

    Verified gas-barrier system

    Use a product and assembly with evidence for the project’s radon-barrier requirements; a general waterproofing coating is not automatically suitable.

  2. 02

    Compatible penetration seals

    Service entries, junctions and joints need continuity within the specified barrier.

  3. 03

    Protective layers

    The design should protect the installed barrier during subsequent construction.

FROM SURFACE TO FINISH

How the work is approached.

A planning overview. The specified system and current technical data define the installation.

01

Test and design

A qualified local radon professional establishes the testing and mitigation strategy.

02

Coordinate barrier details

Review the slab, walls, service entries and other measures in the complete design.

03

Inspect and verify

Check barrier continuity and complete the professional’s testing and verification plan.

PLAN YOUR PROJECT

Let’s start with your surface.

A coating alone is not a substitute for radon testing or professional mitigation. Ask a qualified local professional to define the approach; we can review product documentation for the specified system.

  • Radon testing and a qualified mitigation designer
  • Barrier continuity at joints and service entries
  • Project requirements and system-specific evidence
