Features

Specifications

Thickness: 0.5mm – 1.5mm	◎ Width: 1200mm, 1500mm
◎ Length: 100m/roll, 50m/roll	◎ Color: any color available upon customer request

Applications

Suitable for waterproofing of various buildings such as roofs, basements, tunnels, etc.; roofing and below-grade waterproofing for civil and industrial buildings; water storage tanks; municipal engineering; bridges; subways; tunnels; dams; and especially for key projects requiring high durability, high corrosion resistance, and resistance to deformation.

Application Method

I. Construction procedure:

Acceptance of screed → Clean substrate → Prepare cement adhesive → Apply reinforcement layer → Install membrane → Apply protection layer → Cure

II. Before bonding:

First, pre-roll the membrane to locate and align it. Then fold both ends toward the center and roll up. Pour the prepared cement adhesive onto the substrate and spread evenly with a trowel. Then unroll the membrane forward, and promptly use a trowel to remove any air trapped inside and scrape off excess adhesive. The bonding rate between the membrane and the screed shall be ≥85%.

III. Joint treatment:

IV. Protection layer:

After the membrane is fully laid, apply a 2 cm thick protection layer of 1:2.5 cement mortar over the waterproofing layer. Apply in two separate coats, with the joint between the two coats staggered by at least 20 cm. The protection layer must be smooth and water- cured. When bonding the Polyethylene polymer polypropylene (polyester) fiber polymer waterproof membrane to the main structure, use cement material mixed with the dedicated “Zhengshun” proprietary powder as the adhesive.

Building application – Part 1:

Building application – Part 2:Anti-seepage for canals and reservoirs; anti-seepage for earth-rock dams.

Other applications:Can be used in metallurgy, chemical anti-pollution, anti-seepage, pipeline waterproofing, mine waterproofing, road and bridge waterproofing, tunnel waterproofing, etc.

Performance

Polyethylene polymer polypropylene (polyester) fiber polymer waterproof membrane complies with GB18173.1-2012 standard.
