Liquid membranes

Liquid membranes

Liquid membranes are most commonly used in applications under tiles or on podium decks where the detailing of a sheet membrane would make the process uneconomic.

Duraseal generally uses polyurethanes because they have a good elongation rate and cure well, allowing for over-coating the next day. We always use a moisture barrier before installing these membranes to stop any water vapour coming through the top layers, which leads to blistering and can cause the membrane to fail.
