        EPDM Rubber Waterproof    Membrane


EPDM waterproofing membrane is a polymer waterproof material world recognized the most outstanding performance, a high elastic waterproof material, is most commonly used as a waterproofing material, is focused on the promotion of the Ministry of Construction of new chemical materials. a. "Dongsheng" brand EPDM waterproofing membrane production equipment and technology for the production of polymer elastomer rubber waterproofing membrane on the most advanced in the world today the continuous extrusion sulfide as one, computer-controlled process is stable. Strict selection of advanced formulations, according to the ISO9001 quality system of production, all of the production process in a controlled state, to ensure the high-performance, high-quality, better density and the "Golden" brand waterproof membrane, no bubbles, no aspect difference to the performance. Product performance to meet or exceed the GB18173.1-2000 standard, and has reached the advanced level of similar foreign products.

EPDM waterproofing membrane with a single layer construction, cold work, light weight, anti-aging, long life, high tensile strength, elongation, adaptability grassroots shrinkage and cracking deformation, the use of a wide range of (- 40 ℃ to 100 ℃) characteristics, excellent waterproof performance, service life of up to 50 years, has been hailed as the king of waterproof.Scope:
A variety of industrial and civil buildings, bridges and culverts, tunnels, dams, reservoirs and other construction projects, and a variety of underground engineering waterproof, moisture barrier.

Product storage, transportation, storage:

Waterproofing membrane and supporting adhesive should be stored in a cool, dry and ventilated warehouse, away from heat. Adhesives containing organic solvents are flammable, use, storage, transport should pay attention to fire safety. Supporting adhesive storage period of one year, to the latter passed the test can be used.

1. Grassroots should be smooth, dry, clean and not crisp, sand, peeling phenomenon.

Before construction should be grassroots cleaned and to eradicate foreign body.

2.The waterproofing membrane completely stalls at the grassroots level, to relaxation of the stress of the sheet. Amount applied in the grassroots grassroots adhesive and the surface of the sheet, pending adhesive sticky hands, smooth paving, compaction.

3.Stones Volume Coil should be highlighted in the first volume overlap edge 100mm, not coated grassroots adhesive, sheet 

4. Requirements Stones at the grassroots level, in order to complete the laying work. Laying must not be violently taut waterproofing membrane.

5. After grassroots Putie completed with special solvent scrub lap portion, sufficiently dried clinch rubber sheet applied to the seams both sides, until the glue sufficiently dried, and then cover the second pass until the gum was dried to a tack-free after, flatten it with a roller compaction.

6..Attention to fire safety in construction, the basement sealed construction site shall be equipped with a good ventilation facilities before construction.
