Compacted grass surface should be smooth, pvc waterproofing membrane manufacturer, drainage slope should meet the design requirements. Cement mortar layer should be cured sufficiently, without crisp, sand, peeling phenomenon. PVC waterproofing membrane with excellent tensile strength and other characteristics of high elongation good. The test product and the use of long construction shown, a good weldability after the hot-air welding joints and the base metal are integrated. Choose waterproof materials are waterproof layer and durable life quality and great influence, pvc waterproofing membrane production, the correct choice, the rational use of waterproof roofing material is one of the key design success or failure, pvc waterproofing membrane sales, although flexible waterproof many types of materials, performance varied, pvc waterproofing membrane with anti-aging, weather resistance, elongation, long service life. At the same time the construction is simple, low cost, ease of maintenance, Heilongjiang pvc waterproofing membrane, good results. Pvc waterproofing membrane performance requirements: Tensile strength: longitudinal ≥7.0mpa, lateral ≥7.0mpa, longitudinal elongation at break ≥150%, lateral ≥150%, pulling longitudinal ≥70kn, lateral ≥60kn, heat resistance 90 ℃, low bending resistance: -20 ℃ no crack, anti-permeability: 0.2mpa24 hour impermeable, puncture resistance impermeable.
