Protecto-drain plugs help installers fix Protecto-drain dimpled membrane to a vertical surface. They are designed to allow a fixing nail to be passed through them and the HDPE membrane and seal the hole so that water cannot pass through the fixing. This keeps the integrity of the waterproof seal.
Installers simply set the HDPE sheet onto the surface area they wish to cover, align the plugs into the dimpled cup (part of the design of the Protecto-drain membrane) and drive a clout nail through the hole manufactured within the plug. The hole will seal as the nail is driven through and the seal will remain intact.
It is not necessary to install a large number of nails and plugs as the membrane is very lightweight and it only needs to be fixed in place for a short time period, until the backfill process takes place. It is best to fix the nails and plugs towards the top of the surface area.
These plugs are available in bags of 100 pieces and can be purchased directly from Wallbarn.
