HDPE wet-laid waterproofing membrane

Product Introduction

Polymer self-adhesive film (non-asphalt-based) waterproofing membrane is specially developed for underground and tunnel engineering, which can form a strong anti-bonding waterproofing membrane with post-pouring concrete structure. The coiled material is a polymer self-adhesive waterproof coiled material with resin polymer (EVA, LDPE, HDPE, ECB, etc.) sheet as the main waterproof material and self-adhesive film on the polymer waterproof substrate. The coil self-adhesive layer and the protective layer against environmental changes have self-healing function. After reacting and consolidating with the liquid concrete slurry, the waterproof layer is formed with the concrete structure without gaps, which prevents the hidden danger of water channeling and can effectively provide the reliability of the waterproof system.

Product Features

1. Unique formula, non-asphalt-based reactive pre-laid polymer self-adhesive membrane waterproofing membrane is made of non-asphalt-based self-adhesive compound and polymer sheet.

2. Polymer self-adhesive film (non-asphalt-based) waterproofing membrane has unique bonding properties, and the peel strength is 2-3 times that of ordinary self-adhesive membrane.

3. High tear resistance, waterproof impermeability, strong hydrolysis resistance.

4. Low temperature flexibility is good, and it can maintain good flexibility when thrown at low temperature of -30 ℃.

5. It is suitable for the pre-paved anti-stick waterproof project of underground and tunnel engineering, and has the impact resistance of the concrete pouring concrete without the need for the protective layer to be directly bound after the construction of the waterproof layer is completed.

6. Waterproof performance is reliable, and the membrane has the advantages of polymer waterproofing membrane and self-adhesive membrane.

7. The base surface requirements are low, saving the construction period, no need to level the base cement mortar, and the wet base surface can be constructed. No bottom and base treatment is required, and it is not affected by the weather, which can save the construction period and reduce the project cost.

8. The construction is simple and fast, and the construction methods are flexible and diverse. According to the actual needs, wide-width coiled materials can be produced to achieve less overlapping, fast construction, low consumption and low cost. During construction, construction methods such as empty paving and mechanical fixing can be selected according to the site conditions of the project, so the construction is more flexible and the waterproof effect is better.

9. Green, environmental protection and safety, no solvent and fuel are needed in the construction process, which avoids the hidden danger of environmental pollution and saves energy.

10. Waterproof membrane and grass-roots empty shop, not affected by the settlement deformation of the base.

Scope of use

1. Traffic engineering: subway, tunnel, tunnel, bridge and other waterproof and anti-seepage engineering

2. Construction works: roof, basement and other waterproof works

3. Water conservancy projects: waterproofing and anti-seepage projects such as reservoir dams, cofferdams, canals and artificial lakes

4. Environmental protection project: landfill, sewage treatment plant, metallurgy, chemical plant and other waterproof, anti-seepage project.

Implementation Standard for Non-asphalt-based Reactive Pre-paved Polymer Self-adhesive Film Waterproofing Membrane: Pre-paved Class P in GB T23457-2009 -8 "Pre-paved/Wet-paved Waterproofing Membrane.

Precautions

It is strictly prohibited to construct in rain, ice and snow days and windy weather above grade 5 (outside the construction of tunnels and caverns), and the ambient temperature for the construction and bonding of self-adhesive film coils should not be lower than 5 ℃.

During transportation and storage, products of different types and specifications shall be stacked separately and shall not be mixed.

The temperature to be avoided shall not be higher than 45 ℃, and the stacking height shall not exceed five layers during square storage of coiled materials.

Prevent tilting or pressure measurement during transportation, and cover with felt cloth if necessary.

Under normal transportation and storage conditions, the product storage period shall be at least one year from the date of production.
