Advantages of Bridge and Roadbed Pre-Compression Water Bags:
Made from high-quality materials, these water bladders offer exceptional durability and aging resistance. This material is not only environmentally friendly and odorless, but also highly impact- and puncture-resistant, ensuring peace of mind and avoiding potential safety hazards during use. Furthermore, its unique design makes installation and removal quick and easy, significantly improving work efficiency.
1) Water Resistance: After being immersed in water, these bags maintain virtually unchanged performance, demonstrating excellent impermeability and stability even under water pressure.
2) Stability:
A. Temperature Stability: This material exhibits excellent temperature stability, preventing flow, blistering, or slipping at high temperatures and cracking at low temperatures. This means it maintains its performance over a range of temperatures.
B. Atmospheric Stability: This material exhibits excellent resistance to aging and corrosion under the combined effects of sunlight, heat, oxygen, and other chemical and microbial agents. 3) Crack Resistance: This material exhibits excellent crack resistance when subjected to load stress and deformation within the allowable range of the building structure, meaning it is not easily broken.
4) Flexibility: For waterproof materials, special emphasis is placed on low-temperature flexibility to ensure ease of construction and prevent brittle cracking.
DER Group ready products advantage:
1. Solid Welding and Sealing Technology
During the weld process, we utilize a solid welding process, using hot air pressure to create a tighter bond between the fabrics. This significantly increases the contact surface width of the lap joint, significantly reducing the possibility of leakage. Air pressure testing has shown this technology to have a near-zero permeability, ensuring superior waterproofing.
2. Weld Densification Technology
To further enhance the waterproofing effect, we utilize a weld densification process. At the weld seams, we use high-quality, specially designed sealing strips, which are welded tightly to the fabric using high-temperature welding. This not only enhances the seal but also provides a double guarantee for waterproofing.
3. Innovative Weld Bridge Heat Sealing Technology
Given the complexities of field construction environments, where uneven surfaces often make construction challenging, we have introduced our unique weld bridge flat heat sealing technology. This technology ensures stable welding machine operation and evenly distributes temperature across the weld seam. It effectively avoids quality problems such as uneven welds, wrinkles, and insufficient heat-sealing strength that may be caused by other construction methods, thereby ensuring the durability of the anti-seepage effect.
