Wave Shaped Building Expansion Joint Rubber Sealing Strip

Product Introduction

This series of wave shaped building expansion joint rubber sealing strips is a specialized waterproof sealing accessory for deformation joints developed specifically for building exterior walls, roofs, curtain walls, bridges, and other engineering projects. Using ethylene propylene diene monomer (EPDM) rubber or chloroprene rubber as raw materials, a continuous wave (accordion style) structure is made through an integrated extrusion molding process. It can freely deform with the expansion, settlement, and displacement of the building structure, and has multiple functions such as waterproofing, anti-seepage, dust protection, and buffering and shock absorption. It is the core accessory for waterproofing and structural protection of building deformation joints.

Core Features

Wave structure, adapted to the unique continuous wave design of structural deformation requirements, can be freely adjusted with the temperature expansion, settlement displacement, and vibration deformation of the building structure, effectively absorbing structural stress, avoiding the failure of rubber strips due to tension and compression cracking, while maintaining continuous sealing at the joints, fundamentally solving the problem of deformation joint leakage.

High quality rubber material, long weather resistance and durable life Selected ethylene propylene diene monomer (EPDM) rubber or neoprene raw materials, excellent high and low temperature resistance, UV resistance, aging resistance, ozone resistance, long-term exposure to outdoor environment is not easy to harden, shrink, crack, can work stably in a wide temperature environment of -40 ℃~120 ℃, long service life, reduce later maintenance costs.

Excellent waterproof and anti-seepage performance, high protection level. The rubber material itself has good water resistance, weather resistance, and anti-seepage performance. Combined with the continuous sealing design of the wave structure, it can effectively prevent rainwater and sewage from infiltrating into the deformation joints, while preventing dust and debris from entering the joints and causing blockage, protecting the structure from erosion, and improving the overall durability of the building.

Easy installation and strong construction adaptability. The product has flat fixed wings at both ends, which can be directly installed on the structures on both sides of the deformation joint through pre embedding, pressure bar fixation, or bonding methods, making construction convenient and efficient; It is also possible to customize specifications for different wave heights, flange widths, and lengths according to engineering needs, to adapt to expansion joint scenarios with different widths and deformations, and has strong universality.

Buffer and shock absorption, protecting the elasticity of rubber materials in building structures, can absorb the impact force generated by building structure vibration and deformation, play a buffering and shock absorption role, reduce structural stress concentration, protect concrete and metal components around deformation joints from damage, and enhance the stability and safety of building structures.
