Most wetroom drains / guleys have dual purpose bodies (not grills ) which are used for tiles and vinyl. Within the body there is a retaining ring which ensures the seal into the drain and under which the vinyl or in this case tanking membrane sits.
Both Dura-ci and Dura-wp can be used for tanking wet room floors over wood.
Providing the floor to be tanked is under 8 m2 in size, has been boarded with 22/25mm ply wood and screwed at 300 centres then Dura-wp can be used.
The use of Dura-wp in these cases makes the fixing into the drain body a much easier job as its only 0.6mm thick so more pliable.
Dura-wp in the above circumstances can be used with Tuff2, Impey Aquadec, Maxxus minimax, LinearFlo-dec, Purus line, Ti-line, Pro4mer and most other recognised makes of wetroom shower tray former.
