Why do you require expansion joints for your concrete structures?

Concrete experiences expansion and contraction due to thermal cycles and various movements, both static and dynamic, to prevent cracking in concrete elements. At Remedial Fixx, we are experts in expansion joint repair. We offer a range of solutions for structural and expansion joint repair, especially for joints and cracks that have deteriorated or sustained damage.

Our repair systems are designed to withstand chemicals, preventing the ingress and egress of water while accommodating expansion and movement.

Our engineers determine the placement of expansion joints to enable sections to move independently, reducing the risk of cracking in structures.

It is essential to seal all expansion joints in concrete structures, whether they are part of an existing or new construction project. This is crucial to control moisture infiltration, prevent corrosion of exposed reinforcing steel, and safeguard the integrity of the concrete joint.

To ensure a secure bond for all joint materials, the inside concrete surface of a joint (nosing) must be clean, dry, and free from voids, cracks, or spalls. Any such issues must be addressed before installing sealant material. Compatible primers are applied to the concrete joint interface before installing polyurethane sealant and pre-molded extruded neoprene rubber materials. Cellular backer rods are used to control the proper depth of polyurethane and silicone sealant and to prevent a three-sided bond. Non-sag sealants are tooled to achieve proper bonding to joint edges and control the sealant's depth at the center of the joint.

Expansion joint systems can be used on many structures such as:

  • Service reservoirs
  • Tunnels
  • Power stations
  • Water and wastewater treatment plants
  • Culverts
  • Silos
  • Water towers
  • Roof connections
