The PVC membrane is made by using polyvinyl chloride resin as main material, blended in defoamer, aging resisting agent and ultraviolet light absorber.While Adding fiberglass mesh, fiberglass non-woven fabrics as inner reinforcement, the product has been greatly enhanced in its tensile strength and durability,which makes it applicable for high-requirement and complicated waterproofing engineering.
1)Tunnels waterproofing of subway, road or rail way, bridges, civil air defense engineering, etc.
2)Industrial/ civil building basement and roof waterproofing, roofing engineering includes plant roof, flat roof, sloping roof, concrete roof, light steel structure roof as well as the interior & exterior roof.
3)Large grain depot, beam field, landfill, artificial lake, pipe trenches & municipal engineering of waterproof, etc.
1)After added with fiber glass,the product has longer service life, high tensile strength & elongation, It can effectively resist the destruction of the waterproof layer due to structure deformation.
2)Superior aging-resistance,low deformation rate to heat,good resistance to wind-uplift, specially applicable for exposed roof system.
3)Good resistance to perforation and mechanical damage.
4)Resistance to chemical corrosion & mildew, especially applicable to tunnel waterproofing and planting roof waterproof engineering.
5)Good low temperature flexibility, flame retardant, self-extinguishing once deviated from fire,
high construction safety and reliability.
Bond well with substrate after hot gas welding, reliable seam welding, Eco-friendly.

1)Different types and specifications of the products should be stacked respectively. Pay attention to ventilation. Storage temperature should not be higher than 45℃, flat storage stack height no more than five layer, put single pile vertical, keep product away from acid, alkali, oil, organic solvent, etc.
2)Transportation to prevent tilt or lateral pressure, cover with cloth if necessary.
3)Under the condition of normal storage & transportation, storage period is one year.
