An expansion joint is commonly located on structures such as bridges, highways and sidewalks. An expansion joint is a mid-structure separation designed to absorb vibration, join objects, or allow movement. In structures, expansion joints can help absorb the expansion and contraction of concrete slabs as a result of temperature changes. Without expa...
Strip seals are flexible neoprene membranes adhered to the joint walls. They adhere well and prevent water ingress, but the seals can tear and disjoin under traffic if incompressible debris settles on top. Compression seals are neoprene or cellular seals in the form of a series of webs that provide outward pressure against joint walls to hold the s...
Seals commonly fail due to adhesion loss and cohesion loss. Adhesion loss is evident when detachment of the seal from joint walls occurs. Adhesion loss is the loss of bond between the sealant and joint walls. Cohesion loss is evident when a tear on or in the seal occurs. Cohesion loss is the loss of internal bond in the sealant.
Conventional expansion joint seals have their own individual disadvantages and common failures. Belzona provides polyurethane sealants that protect expansion joints from incompressible debris while offering advantageous mechanical properties including high movement capability, high elastic recovery, and high abrasion resistance. In addition, Belzon...
For this repair, we used: 1. Belzona 4111 (Magma-Quartz) and a wooden batten to reform the nosings of the joint 2. Belzona 2221 (MP Fluid Elastomer) and a backer road to create a new joint sealant 3. Belzona 5231 (SG Laminate)to provide protection of the expansion joint and an aesthetic look Additionally, we utilized Belzona 9111 (Cleaner/Degreaser...
