Introduction

Radon cavity barriers are built into all exterior walls around the building at floor/wall level. Their function is to arrest gas rising within the cavity/wall from permeating the structure. Barriers link with the protective oversite membrane.

Rising gas arrested by the barrier is discharged out of the structure via appropriately located Cavibricks. The barrier is outward-stepping and shaped so any water penetrating the external masonry skin at higher level can be evacuated from the wall via Caviweeps located within perp joints.

Barriers are based on the Cavicloak design and manufactured in profiles to suit the specific construction detail. On site long runs can be swiftly formed by lap linking and sealing adjacent lengths. Preformed corners, change of level links and threshold barriers are manufactured to suit. In some instances the Radon Barrier can also function as the wall horizontal DPC, eliminating the need for this to be addressed separately.

 

Use

Preformed cavity barriers designed to minimise the entry of radon gas into the building.
