According to the main waterproofing constituent materials used for waterproofing, waterproofing membranes can be divided into three major categories: bituminous waterproofing membranes,
modified polymer waterproofing membranes, and synthetic polymer waterproofing membranes.
There are various types of waterproofing membranes included, such as PVC waterproofing membranes,EVA waterproofing membranes, PE waterproofing membranes, ECB waterproofing membranes, etc.
Bituminous Waterproofing Membranes
Bituminous waterproofing membranes are made by impregnating and coating bitumen on a base (such as base paper or fiber fabric),
and then spreading powdery or flaky separating materials on the surface to form rollable sheet-shaped waterproofing materials.
Bituminous waterproofing membranes are mainly classified into the following types:
1. Felt (production and use have now been prohibited).
2. Petroleum bitumen glass cloth felt.
3. Petroleum bitumen glass fiber mat felt.
4. Aluminum foil faced felt.
