Tunnel Seam Splicing Foam is a material designed to solve the problem of seams encountered in tunnel construction. It is primarily used to fill and seal gaps created by structural changes inside or outside of tunnels to prevent moisture infiltration, air circulation, and other factors that may affect the stability and safety of the tunnel. This type of foam usually has good elasticity and compression properties, can adapt to different shapes and sizes of seams, and maintains its sealing effect after prolonged use.
Features
- High elasticity and recovery: Tunnel seam splicing foam has excellent elasticity, even if extruded by external forces, it can be quickly restored to its original state, to ensure the sealing performance under long-term use.
- Strong weather resistance: made of special materials, it can resist the effects of UV radiation, extreme temperature changes and chemical corrosion and other environmental factors.
- waterproof and breathable: effectively prevent the passage of water while allowing water vapor to be discharged, reducing the occurrence of condensation.
- Easy and fast installation: no complicated tools are needed to complete the installation work, suitable for all kinds of construction conditions.
- Environmentally friendly and non-polluting: Strictly control the emission of harmful substances during the production process, in line with green environmental standards.
Application
- New tunnel construction
- When building new tunnels, the foam is placed between the formwork before the concrete is poured to form a seamless connection after the concrete has hardened.
- Used to treat the joints between different sections to ensure the continuity of the overall structure.
- Old Tunnel Rehabilitation
- Repair and reinforce the aged tunnels that have been built but with potential leakage problems, and fill the cracks to achieve waterproofing.
- Replacement of old and failed sealing materials to improve the service life of the whole tunnel system.
- Underground Space Development
- In addition to traditional highway and railroad tunnels, it is also widely used in underground space construction projects such as urban underground parking lots and commercial streets.
- It is suitable for any occasions that need good waterproof performance and have certain requirements for aesthetics.
