Introduction

Cavistrap is supplied predrilled for immediate fixing. It may be employed to support and retain soft and flexible DPCs to the inner leaf, as recommended by the DPC manufacturers. The cavistrap is not flat but purposely slightly arched to promote effective securing pressure when fixed, despite irregularities of the inner skin surface. Use of the cavistrap provides an easy and cost effective way of establishing defined and consistent fixing against all types of inner skin such as block, cast concrete and timber.

Use

Preformed fixing aid for use with polymer, bitumen and polythene roll DPC.
