EPDM waterproof membrane
EPDM Waterproofing Membrane introduction：
EPDM Waterproofing Membrane using a cold feed extrusion continuous vulcanization process equipment with internationally advanced level, selecting high-quality raw materials of EPDM rubber, adding reinforcing agents such as carbon black, nano-modifiers, plasticizers, vulcanization accelerators, and other processing aids, through processes such as compounding, refining, filtering, extrusion molding, continuous vulcanization, adhesive treatment, inspection, etc., to produce high-elasticity synthetic polymer waterproofing membranes.
EPDM Waterproofing Membrane applications：
It is suitable for the waterproofing of roofing and underground waterproofing projects of industrial and civil buildings, reservoirs, municipal works, subways, tunnels, etc. It is especially suitable for key waterproofing projects with high requirements on durability, corrosion resistance and easy deformation.
EPDM Waterproofing Membrane advantages：
1. The special modified molecular structure effectively solves the problem of insufficient overlap of EPDM adhesives at home and abroad;
2. Long service life, anti-aging, roofing materials can be used for more than 20 years, and underground can be used for 50 years;
3. High elongation, high tensile strength, and small dimensional change after heat treatment;
4. It has good resistance to plant root penetration and can be used as a waterproof layer for planting roofs;
5. Good low temperature flexibility, good performance to adapt to changes in ambient temperature;
6. The construction is convenient and the lap joint is firm and reliable;
7. Resistant to chemical corrosion, can be used in special occasions;
8. Easy maintenance and low cost;
9. Easy to handle details;
10. Good perforation resistance.
Installing EPDM Waterproofing Membrane steps:
1. Horizontal Surface Installation: First, a baseline should be drawn on the substrate, then install from low to high. When unrolling the tape, remove the release liner simultaneously. The tape should overlap the baseline, with a width of ≥50mm (full adhesion) or ≥50mm (partial adhesion). After installation, use a rubber roller to firmly press the tape.
2. Vertical Surface Installation: Install from low to high vertically, while unrolling the tape and removing the release liner. The overlap width should be the same as above. After installation, use a rubber roller to firmly press the tape.
3. Tape Finishing: Seal the tape ends with sealant and then fix them with metal strips. Seal the fixing screws and top seams.
4. Construction Inspection: Check all self-adhesive tapes for tears, damage, bubbles, curled edges, or openings. If defects are found, cut open at the defect, remove the bubbles, and restore. Paste another piece over the area, press firmly.
6. The waterproofing layer and special details such as expansion joints and embedded pipe roots must undergo engineering acceptance to meet design requirements and construction standards.
7. The substrate of the waterproofing layer should be solid, flat, with rounded or obtuse angles at internal and external corners, and clean. The adhesive should be evenly applied without leaks or penetration.
8. Do not use non-exposed tapes in exposed environments.
9. Do not install self-adhesive tapes on frozen substrates.
10. Construction should not be carried out on contaminated or excessively moist substrates.
11. Remove the release liner from the tape packaging only before and during installation.
12. Do not use materials from other manufacturers without verification.
