What precautions should be taken when constructing with Guizhou EVA waterproof boards at non-standard temperatures?
Release date:
2020-10-29
Waterproof sheets, also known as geomembranes, are commonly categorized based on thickness: geomembranes thicker than or equal to 0.8mm are referred to as waterproof sheets, while those thinner than 0.8mm are simply called geomembranes. These materials are made from high-molecular polymers and serve as effective impermeable barriers. They come in two main types: homogeneous waterproof sheets and composite waterproof sheets.
Guizhou Tongren EVA Waterproof Membrane It features excellent impermeability, high barrier properties, superior puncture resistance, no chemical contamination, and outstanding resistance to acids, alkalis, and a wide range of chemicals. Additionally, it boasts exceptional elongation, wear resistance, dimensional stability, and strong adhesion, making it easy to install. These characteristics make it ideal for meeting the demands of civil engineering applications such as seepage control, isolation, reinforcement, and crack prevention in projects spanning water conservancy, municipal infrastructure, construction, transportation, as well as subway systems, tunnels, and large-scale engineering works. Thanks to its use of advanced polymer materials and the inclusion of anti-aging agents during production, this product can also be effectively utilized in environments with non-standard temperature conditions. It is commonly employed for seepage control in embankments and drainage channels, as well as for preventing contamination in waste disposal sites.
Guizhou Tongren EVA Waterproof Membrane Performance features:
Performance features:
1. Excellent impermeability; high barrier properties; superior puncture resistance; free from chemical contamination; resistant to acids, alkalis, and a wide range of chemicals; boasts outstanding elongation and abrasion resistance; exhibits excellent dimensional stability; offers strong adhesion; and is easy to install.
2. Strength – At the same basis weight, the tensile strength in all directions is higher than that of other needle-punched nonwovens.
3. Kang UV light exposure—possesses highly effective UV resistance.
High-temperature resistance—capable of withstanding temperatures up to 230°C while maintaining structural integrity and its original physical properties even at elevated temperatures.
4. Permeability and Planar Drainage — Guizhou Tongren EVA Waterproof Membrane Thicker and needle-punched, it offers excellent planar drainage and vertical water permeability, maintaining these properties even after many years.
5. Creep Resistance — Guizhou Tongren EVA Waterproof Membrane It exhibits superior creep resistance compared to other geotextiles, resulting in excellent long-term performance. Additionally, it is highly resistant to erosion by common chemicals found in soil, as well as to corrosion from fuels like gasoline and diesel.
6. Ductility — Guizhou Tongren EVA Waterproof Membrane It exhibits excellent elongation under a given stress, allowing it to conform to uneven and irregular substrate surfaces.
So, Guizhou Tongren EVA Waterproof Membrane What precautions should be taken when constructing at non-standard temperatures?
1. Installation must be done using an embedded method; the covering thickness should not be less than 30 cm.
2. The renovated seepage control system should consist of: a cushion layer, an impermeable layer, a transition layer, and a protective layer.
3. The soil must be firm to prevent uneven settlement and cracking. Any grass or tree roots within the seepage-proof area should be removed. At the contact surface with the Guizhou Tongren EVA waterproof membrane, apply a protective layer of fine-grained sand or clay.
4. During laying Guizhou Tongren EVA Waterproof Membrane Don't pull it too tightly—embedding the ends into the soil in a wavy pattern works best, especially when anchoring to rigid materials, where some expansion and contraction should be allowed.
5, Guizhou Tongren EVA Waterproof Membrane During construction, avoid letting stones or heavy objects directly impact the Guizhou Tongren EVA waterproof membrane. Ideally, install and lay the Guizhou Tongren EVA waterproof membrane simultaneously while applying the protective layer.
