CHEMPLAN PVC waterproof membrane is a high performance waterproofing sheet manufactured using PVC resin as its primary
material, compounded with appropriate proportions of plasticizer, anti-UV agent, and stabilizer, then produced through an extrusion
moulding process. Due to its unique product formulation, the service life of this membrane is significantly longer than conventional
waterproofing materials, thereby extending the overall service life of the entire waterproofing system.
