EVA Polymer Self-adhesive Waterproofing Membrane
It is a self-adhesive waterproofing membrane with polymer sheet as the surface (or base), butyl and styrene-butadiene polymer modified asphalt as the self-adhesive material, and is compounded by a special process. It solves many difficulties in the construction of polymer waterproofing sheets, and at the same time combines some characteristics of polymer sheets and self-adhesive membranes, thus realizing the superimposed waterproofing function.
Transportation And Storage
1. Products of different specifications should be stacked separately and should not be mixed;
2. The height of the coiled material should not exceed five layers when laid flat, and single layer when stacked cubically
3. Avoid sun and rain, and pay attention to ventilation.
4. Prevent tilting and lateral pressure during transportation, and cover with tarpaulin if necessary.
5. The storage temperature should not be higher than 45℃. Under normal storage and transportation conditions, the storage period is one year from the date of production.
Application Areas
Waterproof projects such as basement floor, side wall, top plate, bottom surface, underground integrated pipe gallery, subway, tunnel, etc.
