SBS waterproofing membrane

SBS waterproofing membrane is used in building walls, roofs, tunnels, highways, landfills, and other places. It is a flexible building material product that can be rolled up to resist external rainwater and groundwater leakage. As a leak free connection between the engineering foundation and the building, it is the first barrier for waterproofing the entire project and plays a crucial role in the entire project.

The inner and outer films are made of blown HDPE raw materials. Print patterns on the surface again. Finally, apply silicone oil. Roll it into a barrel shaped coil material. Used as a substrate for mud cleaning and rolling lines. It should be resistant to high temperatures. No leakage. And also ensure the use. Burning with an open flame leaves no residue.
Waterproof coiled materials are required to have good water resistance, stability to temperature changes (no flowing, bubbling, stirring under high temperature; no embrittlement under low temperature), certain mechanical strength, extensibility, fracture resistance, flexibility and aging resistance.

1、 The types of S waterproofing membranes vary according to the body of the waterproofing material, mainly including polyester felt, fiberglass felt, fiberglass reinforced polyester felt, and so on. If classified according to different covering materials, it is mainly divided into several types such as sand mining, shale flakes, fine sand, PE film, etc. According to different specifications, the width and thickness also vary. For example, polyester tire waterproofing membranes include three millimeters, four millimeters, and five millimeters.

2、 If the types of SBS waterproofing membranes are classified according to their physical and mechanical properties, they are mainly divided into two types: Type I and Type II. Because they can adapt to different temperatures during use, they can be divided into two types: -20 degrees Celsius and -25 degrees Celsius.

SBS waterproofing membrane has good temperature resistance when used, which can withstand temperatures from minus 25 degrees Celsius to over 100 degrees Celsius. It has good elasticity, fatigue resistance, and can achieve a body length of up to 1.5%. It is resistant to severe cold and deformation, so it is very popular in buildings.

Waterproof rolls are divided into 5 types

Polyester felt based elastomer modified asphalt waterproofing membrane, fiberglass reinforced polyester felt based membrane, fiberglass felt based membrane, mineral aggregate waterproofing membrane, and waterproofing membrane with fine sand isolation material.
1. Polyester felt based elastomer modified asphalt waterproofing membrane is suitable for roof and underground waterproofing projects in industrial and civil buildings.
2. Fiberglass reinforced polyester felt base roll is suitable for mechanical fixation of single-layer waterproofing, but it needs to pass wind load resistance tests.
3. Fiberglass felt based rolls are suitable for structurally stable general roofing and underground waterproofing projects;
4. The exposed use adopts a waterproof roll material with an opaque mineral aggregate as the upper surface isolation material.
5. Waterproofing for underground engineering should use waterproofing rolls with surface isolation materials made of fine sand.
