Description
RIW Cavity Drain Brick Plugs
RIW Cavity Drain Brick Plugs are specially designed fixings for mechanically securing RIW Cavity Drain R20 and RIW Cavity Drain R7 studded membranes to masonry and concrete walls in below-ground waterproofing systems. Manufactured from durable polyacetal, each 75mm long plug features a uniquely shaped 30mm conical head that matches the profile of the cavity drain membrane studs, ensuring effective load transfer and a secure fixing without compromising the waterproofing system. When used in conjunction with RIW Sealing Rope, Brick Plugs create a sealed fixing point that maintains the integrity of the cavity drainage membrane.
Designed for use in pre-drilled soft brick or stone substrates, RIW Brick Plugs provide a reliable fixing solution for dry lining systems, timber battens and masonry lining walls. A 5mm hole through the shank allows additional fixings such as screws or screw-in brick ties to be installed, making them an essential component of professional basement waterproofing and cavity drain membrane installations.
