What is EPDM waterproofing membrane?
EPDM waterproofing membrane, using the production of polymer elastomer rubber waterproofing membrane the most advanced continuous extrusion vulcanization as one of the production equipment and technology, computer control, process stability, strict material selection, advanced formula, according to the ISO9001 quality system organization of production, the whole production process is always in a controlled state, to ensure the high elasticity and high quality of the product; It has the characteristics of strong adaptability to shrinkage and deformation of the base layer, wide operating temperature range (-40°C to 100°C), superior waterproof performance and long service life;
What are the basic features of EPDM waterproofing membrane?
1. The special modified molecular structure effectively solves the problem of overlapping of EPDM adhesives at home and abroad.
2. Excellent anti-aging performance, service life up to 50 years.
3. Extremely high elongation, small change in heat treatment size.
4. EPDM waterproofing is resistant to plant root penetration, and can be made into a waterproof layer for planting roof.
5. Good flexibility at low temperature, good performance to adapt to environmental temperature changes, convenient construction, firm and reliable lap joint, no environmental pollution.
6. Chemical resistance, can be applied to special occasions.
7. Easy maintenance and low cost.
8. Easy to repair in detail.
9. Good perforation resistance.
What is EPDM waterproofing membrane used for?
1. EPDM Waterproofing Membrane is suitable for all kinds of building roofs, basements, tunnels and other building waterproof projects;
2. It is suitable for waterproofing of roofing and underground engineering, reservoirs, municipal, bridges, subways, tunnels, dams and other projects of civil and industrial buildings;
3. It is especially suitable for key waterproof projects with high durability and corrosion resistance requirements and easy deformation.
