NSPSA polymer adhesive pre-paved waterproof roll material (non-asphalt) is a kind of multi-layer composite waterproof material with superior performance constructed by pre-laying reverse adhesion method, which is mainly composed of high density polyethylene (HDPE) sheet, polymer pressure-sensitive adhesive and self-developed polymer adhesive sand protective layer.

A permanent,continuous organic combination with concrete,even if broken,prevents water form flowing through the water and structureUnaffected by deformation at the base.Without the protection,layer,the steel bar can be reinforced afer the laying,andthe structural concrete ca. / be conveniently constructed without the need for the bottom oil,the chamfering and the strengthening layer. Provide complete permanent sealing at the overlap and trim areas.ln a long immersion environment,the peel strength remains high.

Underground waterproofing,such as basement,subway,nuclear power,urban comprehensive corridor,open-cut tunnel,underground tunnel,etc.
