Rubber membrane is manufactured from synthetic EPDM rubber. The EPDM rubber membranes is a single-ply membrane that can be used for various applications such as waterproofing of basements, roofs/terraces, expansion joints, wet areas (toilet blocks), facades, etc. It is a single product that can be used for waterproofing most parts of a building. The EPDM rubber waterproofing membranes are techno-commercially much better than substitutes such as bitumen membranes, crystalline products, admixtures, various coatings, etc. The use of these products may be avoided in projects where EPDM rubber membranes are used. The EPDM waterproofing membranes are an excellent substitute to the torch-on membranes.
Advantage:
Architects, roof consultants and contractors have come to depend on EPDM's time tested, long-term performance.

Application:
1) Roofs, basement, toilet, bridge, underground, tunnel and dam.
2) Industrial and civil building waterproof.
3) Geo-synthetic liner for swimming pool, channels, irrigation system
4) Especially for projects with high requirements in durability, anti-corrosion and deformation.
Construction Method:
1). Ensure all surface are clean,dry and dust-free. Remove any loose particles and any rust with a wire brush & soft broom.
2).Roll out the membrane.
3).Remove the backing paper and place the adhesive side to the previously prepared surface.
4).To ensure a tight contact-smooth the tape down with a dry cloth, remocing all the air bubbles;
5).Press the tape to the surface firmly once in position.
6).Smooth flat all edages with a wallpaper roller or trowel.
7).After use reseal pack and store upright in cool,dry condition.
Storage and Transportation:
1) Waterproof materials should be stored under dry and ventilated conditions.
2) Different types of membranes must be piled separately.
3) Under usual condition, storage period is one year since production date.
4) Waterproof materials should be put vertically during transportation.
5) It should be kept away from sunshine and rainwater.
6) Transport and storage process should be away from the fire source, storage temperature does not exceed 35 ºC, the storage period is 1 year.
