Product Classification, Features, and Construction Techniques for Guizhou EVA Waterproof Membranes Used in Tunnels
Release date:
2020-10-23
Tunnel waterproofing is a key component of tunnel engineering's drainage and water-protection plan. If the surface-level waterproofing of the tunnel is inadequate, groundwater can seep in, compromising operations and shortening the tunnel's service life. Among these factors Guizhou Tongren EVA Waterproof Membrane It is a waterproofing material made primarily from polymer-based polymers, capable of preventing both liquid leakage and gas evaporation. As a result, it has been widely used in railway tunnel construction projects.
1. Guizhou Tongren EVA Waterproof Membrane Product Categories:
① Classified by color: Tunnel-specific Guizhou Tongren EVA Waterproof Membrane , including: Gray-black waterproof board , off-white (porcelain white) waterproof board, white translucent waterproof board.
② Based on the manufacturing process and type of construction work, EVA waterproof boards for tunnels can be categorized into: fully composite waterproof boards, strip-type composite waterproof boards, dot-pattern composite waterproof boards, and strap-type waterproof boards.
(PS: Composite waterproof membrane—typically made with short-fiber needle-punched geotextile, weighing between 200 and 400 g/㎡)
2. Guizhou Tongren EVA Waterproof Membrane Features
1. Facilitates the diffusion of water vapor
2, Guizhou Tongren EVA Waterproof Membrane Inherent weldability
3. High strength with significant ductility
4. Reflects solar radiation without requiring a protective layer
5. Waterproof boards are self-extinguishing.
6. Able to resist external chemical contamination
7. Suitable for various installation methods and roof shapes
8. A reasonable service life of 25 years or more
9. Strength – At the same basis weight, the tensile strength in all directions is higher than that of other needle-punched nonwovens.
10. UV-Resistant—Features high resistance to ultraviolet light.
11. High-Temperature Performance – Withstands temperatures up to 230°C, maintaining structural integrity and original physical properties even under extreme heat.
12. Permeability and Planar Drainage—The waterproof membrane, being thicker and needle-punched, exhibits excellent planar drainage and vertical water permeability, maintaining these properties even after many years.
13. Creep Resistance – The waterproof membrane exhibits superior creep resistance compared to other geotextiles, ensuring excellent long-term performance. It is also highly resistant to erosion by common chemicals found in soil, as well as to corrosion from fuels like gasoline and diesel.
14. Flexibility – The waterproof membrane exhibits excellent elongation under constant stress, allowing it to conform to uneven and irregular substrate surfaces.
3. Guizhou Tongren EVA Waterproof Membrane Construction Technology:
① Guizhou Tongren EVA Waterproof Membrane Choose a simple, self-made vehicle platform with a 6-meter-long chassis. Before installation, the waterproof panels—designed according to the overall width—are pre-cut and bonded together outdoors into modular waterproof sections. Ensure the adhesion is strong, and each joint must be compacted at least six times for maximum durability.
② Guizhou Tongren EVA Waterproof Membrane Before installing the secondary lining, construction work is carried out using a nail-free suspension system to ensure precise placement of the waterproofing panels. During installation, markings are made on the preliminary anchor rod support system, aligning with the suspension straps located behind the waterproofing panels. Next, holes are drilled using a hand-held electric drill, followed by the insertion of expansion wood screws. Finally, hooks are attached to these wood screws. Importantly, the positioning of the wood screws must account for the required overhang of the waterproofing panels.
EVA material is a superior choice—both domestically and internationally—for producing waterproof membranes. Its molecular weight ranges from 20,000 to 50,000. By adjusting the proportion of vinyl acetate content, its properties can be fine-tuned to suit specific product structures, making it versatile enough to meet a wide variety of application needs. EVA boasts excellent flexibility, cold resistance, elasticity, stress-crack resistance, and a lightweight profile—qualities that make it particularly well-suited for waterproofing the inner surfaces of arched roofs.
