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 roll shape to resist external rainwater and groundwater leakage. It is one of the important varieties of waterproof materials in building engineering.

Today, the editor is here to share with you the types of waterproofing membranes, hoping that you can learn a little from them.

Asphalt waterproofing membrane: a rollable sheet-like waterproofing material made by immersing asphalt on the tire base and then sprinkling isolation material on the surface.

1、 Modified asphalt waterproofing membrane: soft, can be made into 4-5mm thickness, can be used as a single layer, divided into: ① SBS modified asphalt waterproofing membrane: can be used in the temperature range of -25-100 ℃, with high elasticity and strong puncture resistance.

② APP modified asphalt waterproofing membrane: A plastic modified asphalt waterproofing membrane made by using APP or APAO, APO modified asphalt as the coating material, polyester felt, fiberglass felt, composite tire cloth as the base material, fine sand, mineral PE film as the negative material, and refined by advanced technology.

2、 Self adhesive waterproofing membrane: No need for adhesive or heating to melt, just peel off the isolation layer and it can be firmly bonded to the base layer.

3、 Polymer waterproofing membrane, such as:

① PVC waterproofing membrane: It is a commonly used thermoplastic polymer waterproofing membrane manufactured through a special extrusion coating process.

② TPO waterproofing membrane: A new type of waterproofing membrane made by using advanced polymerization technology to combine ethylene propylene rubber and polypropylene with thermoplastic polyolefin (TPO) synthetic resin as the base material, and adding antioxidants, anti-aging agents, and softeners. It belongs to the synthetic polymer waterproofing membrane category.

4、 Root puncture resistant waterproofing membrane, such as:

① SBS modified asphalt root puncture resistant waterproofing membrane: including copper based SBS root puncture resistant waterproofing membrane and chemical resistant SBS root puncture resistant waterproofing membrane.

② PVC root puncture resistant waterproofing membrane
