Delta Flexidri Plus Plugs are used to mechanically fix Delta Cavity Drainage waterproof membranes to basement walls.
They feature a unique expanding shaft detail that means they work really well with loose or friable substrates, to securely fix membranes in place.
Delta Flexidri Plus Plugs feature a unique rubber grommet, that allows for easy sealing to the waterproof membrane.
They also feature a pre-formed 5mm sealed hole to accept 5mm or size screws. This allows for the fixing of dry lining or timber battens.
