In many underground waterproof projects, it requires a special waterproof method—empty-applied. In this situation, develops a new series of waterproof membrane—double-side self-adhesive waterproof membrane. It is a combination of self-adhesive rubber/bitumen compound, reinforced material and double release paper. This series of membrane is designed for the waterproofing of underground construction such as tunnel, subway, basement ,roofs and pools etc.
Wet - application installation procedure:
1.Base processing:the base surface must be clean,solid,level,dry;no grit,rift and loosing dust. For a large recess,fill it with cement mortar and then level it. Remove the protrusion and clean dust.If working on base slab or lateral face,water lowering should be done.
2.Plaster cement grout within the scope where membrane is paved.(Plastering cement grout in a large area at one time is not recommended, it’s better to plaster cement grout along the membrane is paved ).
the thickness of cement grout shall be determined according to the smoothness of substrate, which is 3-5mm in general.
3. Pull off relaese paper, pave membrane onto the fresh cement grout.
4.Join side laps(overlap) by adhering membranes with each other (minimum width of 60mm)
When membranes installation are completed, do not move or walk on them, the strongest and overall adhesion can be realized after about 48 hours (cement become cured,the exact time depend on climate)
5.Press membranes tightly to make sure the trapped air is excluded
Details treatment incuding inner/outer corners,pipes,chimneys and others
In the procedure of wet application, no primer is needed. So the time for waiting the primer to dry is omitted, the whole construction period can be shortened drastically. Secondly, the cost for primer is deducted. Above all, the integral adhesion between membrane and cement grout offers the best waterproof solution.
