What are the types of polymer waterproof membranes

Waterproof membrane is mainly used for building walls, roofs, tunnels, highways, etc. It is a flexible building material product that can be rolled into a membrane, which can resist the leakage of external rainwater and groundwater. It is an important waterproof material in construction engineering. One of the varieties.

Today, the editor will share with you the types of waterproof membranes, and I hope you can learn a thing or two from them.

1. Modified bitumen waterproof membrane: soft, can be made into 4-5mm thickness, can be used as a single layer, divided into:

①SBS modified bitumen waterproof membrane: It can be used in the temperature range of -25-100℃, has more elasticity and strong puncture resistance.

②APP modified asphalt waterproofing membrane: use APP or APAO, APO modified asphalt as the dip coating material, use high-quality polyester felt, glass fiber felt, composite tire cloth as the tire base, and use fine sand and mineral PE film as the film material. Plastic modified bitumen waterproof membrane refined by advanced technology.

2. Self-adhesive waterproof membrane: no adhesive, no need to heat and bake to melt, just tear off the isolation layer, and it can be firmly bonded to the base layer.

3. Polymer waterproof membrane, such as:

①PVC waterproof membrane: It is a widely used thermoplastic polymer waterproof membrane, which is manufactured by a special extrusion coating process.

②TPO waterproof membrane: a new type of waterproof membrane made of ethylene-propylene rubber and polypropylene, using advanced polymerization technology, adding antioxidants, anti-aging agents, softeners and other thermoplastic polyolefin (TPO) synthetic resins, It is a synthetic polymer waterproof membrane.
