Chongqing EVA Waterproof board ,选用优质乙烯 - Vinyl acetate copolymer, a thermoplastic with rubber-like elasticity, gives finished products exceptional flexibility. Handling intricate details—such as edges, corners, and pipes—is remarkably simple and quick. Additionally, the material is specially infused with an antibacterial agent to prevent microbial attack, significantly extending the product's lifespan. It also boasts excellent resistance to aging, allowing it to maintain its performance—and even last longer—when buried underground. 50 More than [number of] years; most importantly, the product is made from completely non-toxic, eco-friendly materials and qualifies as a green engineering material promoted for nationwide use by the government.
Chongqing EVA Waterproof board Thanks to its stable chemical properties, it boasts high tear resistance, excellent puncture resistance, superior waterproofing and anti-seepage performance, as well as outstanding hydrolysis resistance. Additionally, an antibacterial agent has been specially incorporated into the material to prevent microbial degradation, significantly extending the product's service life. The product also exhibits broad compatibility with a wide range of adhesives, ensuring strong and reliable bonding—thereby boosting construction efficiency. Moreover, it’s easy to apply and doesn’t require specific moisture levels in the substrate; as long as there’s no visible water present, construction can proceed smoothly without compromising quality. Finally, its exceptional aging resistance allows for a remarkably long service life, even when buried underground. 50 For many years, ensuring the construction's service life while reducing long-term maintenance costs.
Chongqing EVA Waterproof board The specific steps are as follows:
1、 Chongqing EVA Waterproof board Preparation work before laying: Substrate requirements: Sweep the laying surface thoroughly, ensuring the base is smooth and the soil is firm. Avoid any unevenness or irregularities, and make sure there are no sharp objects present.
2、 Chongqing EVA Waterproof board Welding: Seam treatment is applied Key procedures typically use hot-welding methods—Chongqing EVA The surfaces of the waterproof panels are heated to melt them, after which pressure is applied to fuse the materials into a single, seamless unit.
3 , For the laid-out Chongqing EVA Waterproof board , the edges and seams must be free of oil, moisture, dust, and other contaminants;
4 Before welding, ensure the two edge films at the joint are properly aligned and overlapped by a specific width—typically, this overlap width is 70mm And smooth, without wrinkles;
5 1. Use a dedicated welding machine for welding.
