Cheap pvc waterproofing membrane for roof construction materials

PVC waterproofing membrane is an excellent high quality polymer waterproof sheet, made of PVC 
resin by adding plasticizer, anti-UV agent, anti aging agent, and stabilizer and other processing 
aids through extrusion and molding. As the highly-recommended product by the Ministry 
of Construction, it is featured by high tensile strength, great elongation, good stability,
small shrinkage, low-temperature performances, good resistance to weathering and root 
penetration, and long service life.
H ( homogeneous polyvinyl chloride plastic waterproofing sheets ) is the principal material used on exposed roof applications, in vacuum or mechanically attached systems. These roofing systems are suitable for new build and refurbishment applications, flat and pitched roofs. It is reliable, and convenient for construction.
L (polyvinyl chloride plastic waterproofing sheets backed with fabric ) is manufactured from pliable PVC with a reinforcement of nonwoven polyester. The PVC contains stabilizers, which make the product resistant 
to high and low temperatures, UV-resistant and makes it flame retardant.
P (polyvinyl chloride plastic waterproofing sheets internally reinforced with fabric ) 
is a with a laminated polyester fleece (or glass fiber fleece) on its interlayer and can be installed 
directly on old roofing underlay. We recommend that all roofs have an inclination of minimum 
1:40 to provide positive drainage.
