ESE 304 EVA waterproof membrane

STAR ESE 304 EVA waterproof membrane consists of different material, the aging proof layer set especially for this series could provide good characteristics of anti-aging, Antioxidant, anti-corrosion.

It has good flexibility, easy to bend, easily operate. Used in kitchen and toilet, swimming pool, pond, yin & yang angles and the tube root. Enable rectangular construction could avoid the next procedure – tile fixing breaks the membranes, and ensure no water leakage in a secondary shut.

Maximum tension (KN/m), ≥20

Tensile Strength/MPa, ≥60

Elongation at break/%, ≥400

Foldability at Low Temperature: -20 °C

Unit Weight per square meter: 400~1200 g, Width, 1.0 meter

Application

Widely used for waterproofing and anti-seepage in industrial & civil building roof, basement, kitchen, toilet & bathroom.

And antifouling, waterproofing and anti-seepage for pools, channels, tunnels, culverts and chemical metallurgical etc.

Construction points:

Substrate cleaning  → preparation of adhesive (prepare on the site) → treatment of complex parts (or additional layers) → laying of composite membrane → water test → construction of protective layer  → completion acceptance

1.      The substrate (screed) shall be cleaned and sprayed with water to ensure moist.

2.      Prepare the cement paste with the PVA glue solution containing 10%~15% of cement and mix it uniformly until there is no precipitation, clot and segregation.

3.      The sealing material is polyether polyurethane. If any other sealing material is used, it shall not contain the mineral oil, petrolatum and other products affecting the chemical properties of polyethylene.

4.      Add an additional layer at the corner, the internal and external corners shall be round until R = 20 mm.

5.      The waterproof membrane shall be laid by means of full adhibiting immediately after the adhesive is coated to ensure bonding quality.

6.      Lay the waterproof membrane while removing the air and excess adhesive to ensure close bonding between the membrane and the substrate or structure layer.

7.      The overlapping width shall not be less than 100mm. the upper and lower layers shall be staggered for one third amplitude with the joints of two adjacent membranes.
