Waterproof membrane is mainly used in building walls, roofs, tunnels, highways, landfills, etc. It is a building material product that can be rolled into a roll shape to resist external rainwater and groundwater seepage. As the first waterproof barrier between the engineering foundation and the building without leakage, it plays a crucial role in the entire project. The main products include asphalt waterproof membrane and polymer waterproof membrane.

Performance of waterproofing membrane:.

1. Water resistance refers to its performance that remains basically unchanged under the action and penetration of water, and has impermeability. Under the action of water pressure, commonly used indicators such as impermeability and water absorption.

2. Temperature stability refers to the performance of SBS waterproofing membrane that does not flow, bubble, or slide at high temperatures, and does not have brittle cracks at low temperatures, that is, the ability to maintain its original performance under certain temperature changes, commonly used indicators such as heat resistance and heat resistance.

3. Mechanical strength, ductility, and fracture resistance refer to the performance of waterproofing membranes in withstanding certain loads, stresses, or without cracking under certain deformation conditions. Commonly used indicators include tensile strength and elongation at break.

4. Flexibility is the ability to maintain flexibility at low temperatures, which is very important to ensure that it is easy to build and not brittle. Commonly used indicators include flexibility, low-temperature bending, etc.

5. Atmospheric stability refers to the ability of PVC waterproofing membrane to resist long-term comprehensive use of chemical erosion media such as sunlight, heat, ozone, etc., commonly used indicators such as aging resistance and thermal aging retention rate.

Advantages of waterproofing membrane:.

Convenient construction, short construction period, no maintenance, not affected by temperature, low environmental pollution, easy to control, calculated accurately with a thick layer of material according to design requirements, convenient for construction site management, not easy to cut corners, layer thickness, empty shops can effectively overcome basic stress (large base cracks can maintain membrane integrity).

Disadvantages of waterproofing membrane:.

According to the shape of the waterproof base layer, it is necessary to measure the cut base layer. For bases with complex shapes, TPO waterproof rolls need to be spliced together with multiple parts. The seams at the overlapping of the waterproof rolls are difficult to bond, and complete and absolute sealing will become the main problem. There is a great potential for leakage, and waterproof materials are also a difficult problem after building protection and leakage repair. Subsequent penetrating damage, debonding of any part, leakage of glue (even only one), and the entire waterproof function of the relevant layer will temporarily faint. If you cannot find broken and defective parts, local repair is impossible, so only redo waterproofing is necessary.

SBS waterproof material specifications: According to material performance, it is divided into National Standard Type I, National Standard Type II, 3mm thick, 4mm thick, and 5mm thick. According to tire base, it is divided into polymer self-adhesive film waterproof roll ester felt, fiberglass felt, and fiberglass reinforced polyester felt. According to isolation materials, it is divided into polyethylene film, fine sand, and mineral pellets, which are generally classified into these models.

According to theoretical statistics, there are 36 types and 3 thickness specifications of SBS waterproofing rolls that meet the requirements of China's "Elastic Modified Asphalt Waterproofing Rolls", totaling 72 specification types. This does not include different widths, special models, etc., but the commonly used ones do not exceed 10. 1. Types are divided into Type I and Type II. 2. Body: Polyester Felt (PY), Fiberglass Felt (G), Fiberglass Reinforced Polyester Felt (PYG). 3. Upper Surface Isolation Material: Polyethylene Film (PE), Fine Sand (S) Liquid Roll, Mineral Granules (M). 4. Lower Surface Isolation Material: Fine Sand (S), Polyethylene Film (PE). 5. Thickness: Polyester Felt. Roll material (3, 4, 5mm) fiberglass felt roll material (3, 4mm) fiberglass reinforced polyester felt roll material (5mm).

The size of sbs waterproof coiled material is different, and the specifications and models of different product types are also different. In terms of thickness, it is generally 3mm, 4mm, 5mm, and most of the width is 1000m. You can choose according to your actual needs. sbs waterproof coiled material has good aging resistance, corrosion resistance, excellent waterproof performance, safe and environmentally friendly materials, and is one of the popular waterproof coiled materials.
