product introduction:

pre-applied material is a waterproof material which is bonded with major structure in the curing process occurred hydration reaction. in the construction, the material is pre laid at the base level, before the concrete is poured into the structure, the isolation film is exposed on the surface. the waterproof layer and the post pouring concrete are bonded together. flat coil used border adhibiting method , the facade of the use of mechanical fixation. wet paving waterproof coiled material is a in construction of cement slurry paste of self adhered membrane and solve the coil in the wet surface of the base construction problems. wet paving method through the flow of cement mortar to achieve the full adhesion between the membrane and the grass-roots level, and the basic level to achieve a close bond and a high degree of adhesion, eliminate the channeling water, establish a solid waterproof system.

  • advantages
  • performance

1,it  has a very high resistance to penetration, impact resistance and tear strength, effectively resist the crack and deformation of the base;
2, the integrity is good, the joints between the joints is tight, it has a high strength and a certain ductility;
3, good stability, high and low temperature resistance, corrosion resistance, aging resistance, long service life;
4, very strong grass-roots adhesion, effectively prevent the phenomenon of channeling;
5, the construction is simple, operability, high degree of freedom, not affected by climate.
