Guizhou Bijie Tunnel Waterproof Board It is a sheet-like waterproof material of a certain thickness, manufactured through processes such as melting, plasticizing, extrusion, three-roll calendering, shaping, and winding—using ethylene-vinyl acetate copolymer (EVA) as the primary raw material, combined with specialized additives and an anti-aging agent. In GB 50108-2008 "Technical Specification for Waterproofing of Underground Engineering," this material is referred to as a plastic waterproof membrane.
Compared to PE, EVA incorporates vinyl acetate (VA) monomers into its molecular chains, which reduces crystallinity while enhancing flexibility, impact resistance, compatibility with fillers, and heat-sealing properties. Additionally, EVA offers superior resistance to environmental stress cracking, along with excellent optical performance and strong chemical corrosion resistance. It is also non-toxic, non-absorbent, and easy to work with, featuring simple construction processes, outstanding handleability, and exceptional repairability. Moreover, EVA has minimal requirements for the construction environment, making it particularly well-suited for applications in confined spaces such as tunnels and pipelines, as well as environments with poor ventilation or significant water permeability.
Guizhou Bijie Tunnel Waterproof Board Due to its excellent chemical stability, it can be safely used even in chemically aggressive wastewater without reacting and compromising the waterproof membrane's integrity or diminishing its superior performance. Additionally, thanks to its wide operating temperature range, it provides reliable protection at any temperature—preventing damage or degradation caused by thermal fluctuations, thus ensuring consistent functionality. Importantly, however, Guizhou Bijie Tunnel Waterproof Board Due to their excellent corrosion resistance, waterproof membranes—given the often harsh, hazardous environments in which they are used—can provide superior protection, ensuring a more sustainable and environmentally friendly safeguard. As a result, employing them as impermeable and anti-pollution materials plays a crucial role in protecting both the integrity of engineering projects and the broader environment, contributing significantly to environmental safety.
Guizhou Bijie Tunnel Waterproof Board Features:
1. Excellent flexibility, impermeability, elongation, and abrasion resistance;
2. Exhibits good isolation and puncture resistance;
3. No chemical pollution;
4. Resistant to acids, alkalis, and various chemicals, with excellent dimensional stability and strong adhesion, making it easy to install.
