METHOD AND APPARATUS FOR INTERCEPTING WATER IN A CAVITY WALL

摘要

A flexible, elongate barrier comprising relatively rigid barrier portions connected by elastomeric joints is introduced slidingly into the cavity of a cavity wall and sealed to the outer leaf of the wall by introducing a portion of the barrier into a slot cut in the inner surface of the wall and/or by providing a water resistant composition which may be injected into the slot. The barrier may form an X or V shaped configuration defining a channel from which water is discharged via drains from the cavity. The barrier portions may be arranged in a flat configuration when the barrier is stored on a reel and moved through a deployed configuration to an installation configuration against the resilient bias of the joint so that they spring out to the deployed configuration to conform to the width of the cavity after installation.
