Use

Pre-shaped DPC barriers to arrest water-wash within cavity wall to specific areas or features.

Introduction

The function of Type Q barriers is to invisibly arrest and reduce water-wash from an area of cavity wall above a given feature or construction detail. Masonry below the barrier level however still remains damp and receptive to rain penetration. The purpose of the barriers is to influence control of water volumes within a wall and minimise damp transmission risk. Arresting barriers differ from conventional cavitrays and DPCs.

The base dimension does not usually travel the full width of the external skin. Arresting barriers can be supplied in almost any special size with dimensions to suit client’s particular needs. Adjoining lengths glove-lap and Siliconbond to make up runs. Please state cavity width being used.
