EPDM waterproof membrane (referred to as EPDM membrane) is a mixture of EPDM rubber with appropriate amount of butyl rubber, vulcanizing agent, accelerator, softener and reinforcing agent, etc., which is filtered by mixing and pulling , Extrusion molding and other processes. Since the main chain in the molecular structure of EPDM rubber has no double bonds, it is not easy to break the main bond when it is subjected to the effects of oxygen, ultraviolet rays, and damp heat, so it has excellent weather resistance and aging resistance. In addition, it has high tensile strength, large elongation, strong adaptability to the expansion or cracking of the base, value, light weight, wide temperature range (long-term use in the range of -40 ~ +80 ℃), is a highly efficient waterproof material . It can also be used for cold construction, easy to operate, reduce environmental pollution, and improve the working conditions of workers. There are sparse type and non-vulcanized type on the market.

1. Excellent anti-aging performance and service life up to 50 years;
2. Extremely high elongation, relatively high tensile strength, and small change in heat treatment size;
3. The plant-resistant root system has good penetration and can be used as a waterproof roof for planting roofs;
4. The special modified molecular structure effectively solves the problem of the existing overlap of EPDM adhesives at home and abroad;
5. Good flexibility at low temperature, good performance to adapt to changes in ambient temperature;
6. Convenient construction, firm and reliable connection, no environmental pollution;
7. Chemical resistance, can be used in special occasions;
8. Convenient maintenance and low cost; convenient handling of details;
9. Good resistance to perforation;

The EPDM waterproof system is composed of EPDM waterproof membrane, system accessories, system design and construction. The waterproof system is advanced and mature, and has been tested by nearly 30 large-scale engineering projects at home and abroad: it is complete and reliable; it includes a full set of application technologies such as full-stick method, empty paving method, mechanical fixing method waterproof system and system supporting materials, node design, construction technology, etc. . The user can choose the most suitable construction method according to the architectural design needs.
Full adhesion method: the base layer is leveled, calendered, dried, coated with the base layer adhesive, the roll is unfolded and positioned, the cleaning lap area is applied, the lap glue is applied, the rolled lap part is treated in detail, and the full adhesion method is adopted: the full adhesion method is adopted The base layer adhesive directly bonds the EPDM roll material to the base layer, and the adjacent rolls are not less than 10cm, and then the EPDM special adhesive is used for the seam overlap to make the roll form a continuous, After sealing the waterproof layer, the surrounding and perforated areas will be flooded according to the specifications.
Construction characteristics:
1. Suitable for any roof.
2. The material is light in weight.
3. Strong resistance to wind load.
Empty paving method: Loosely spread the EPDM waterproof membrane on the base layer on the large surface, the overlap between the two sheets is not less than 10cm, and then use a special adhesive to bond the lap joint. At 10cm, then use special adhesive to bond the lap seam. Afterwards, according to the requirements of the specification, the surrounding area and the perforated area shall be flooded.
Empty paving method: unwinding and positioning of coiled material, cleaning and overlapping area, application of overlapping glue, rolling and overlapping area, detailed treatment and completion of inversion method: it is a construction method of placing thermal insulation layer on the waterproof layer.
The empty paving method and the upside down method can be applied to any underground and roof that can carry heavy objects. The general roof slope should not exceed 1:6. Construction features: It is suitable for underground waterproofing, manned roofs, driving roofs, and planted roofs.
Low construction cost. The construction speed is fast.
Mechanical fixing method: unwinding and positioning of the coil, mechanical fixing, cleaning and lap area, coating of lap glue, rolling and overlapping parts, detailed treatment and completion of the mechanical fixing method: it is to fix the EPDM waterproof coil with metal bead A construction method on the grassroots.

Construction characteristics:
1. It is generally used for wood, concrete, metal and other base roofs.
2. Construction is not affected by climate.
3. The construction speed is fast.
