Product Description
EVA tunnel waterproof board is a waterproof material used in tunnel construction. Its main function is to prevent water infiltration and ensure the dryness and stability of the tunnel.
EVA tunnel waterproofing board is made of ethylene vinyl acetate copolymer (EVA), which has excellent heat resistance, cold resistance, and aging resistance. In addition, it also has high tensile strength and tear resistance, and can withstand various stresses in tunnel construction.
In China, there are many manufacturers of EVA tunnel waterproof boards, and the quality is also uneven. Therefore, when choosing EVA tunnel waterproof panels, it is important to choose products produced by reputable manufacturers and ensure that they comply with relevant national standards.
Overall, EVA tunnel waterproofing board plays an important role in tunnel construction, with good performance and broad application prospects

Installation Instructions
The installation of tunnel waterproofing panels is a crucial construction process that requires following certain standards and steps. The following are installation instructions for tunnel waterproofing boards:
Preparation: Before installing the waterproof board, ensure that the tunnel is clean, dust-free, and free of oil stains, and keep it moist to ensure that the waterproof board is firmly bonded to the base layer.
Laying waterproof board: Lay the waterproof board flat on the tunnel base layer, ensuring that the board is flat and free of wrinkles. During the laying process, it is necessary to ensure that the waterproof board is firmly bonded to the base layer and avoid hollowing.
Welding construction: After the waterproof board is laid, welding construction should be carried out. Welding should be uniform and firm to ensure the overall sealing performance of the waterproof board.
Joint treatment: The joint treatment of waterproof boards is a crucial step. The joints should be welded with hot air or sewing machine to ensure good sealing. During the welding process, dirt and oil stains at the joints should be cleaned and a base treatment agent should be applied to improve the bonding strength of the joints.
Construction joint treatment: During the construction process, efforts should be made to avoid damage to the waterproof board. If unavoidable, the damaged area should be trimmed neatly and coated with base treatment agent to ensure that the waterproof performance is not affected.
Waterproof layer inspection: After the completion of waterproof board construction, strict inspection should be carried out. The inspection content includes the integrity of the waterproof layer, welding quality, joint treatment, etc. Any issues discovered during the inspection should be promptly rectified.
Construction acceptance: After the completion of tunnel waterproof board construction, acceptance should be carried out. The acceptance criteria include the integrity of the waterproof layer, waterproof performance, construction quality, etc. Only after passing the acceptance inspection can the next construction process proceed.
In summary, during the installation process of tunnel waterproof panels, strict adherence to construction specifications should be followed to ensure the quality of the waterproof layer. Only in this way can the dryness and stability of the tunnel be ensured, and the service life of the tunnel be extended.
