Expansion Joints
Expert Solutions to Strengthen Structures and Improve SafetyConcrete will expand and contract on site during thermal cycles and between static and dynamic movements so each concrete element does not crack.
A design engineer normally specifies where to place expansion joints to enable sections to move independently and to reduce cracking in structures (i.e. paving, tilt-wall panel construction, warehouse slabs, concrete basins, retaining walls, water retaining structures, parking garages, docks, piers, etc.)
Epoxy Design is committed to excellence, safety, and high standards.

Slab Joint Installation
All concrete expansion joints—whether in new or existing structures—must be properly sealed to prevent moisture intrusion, corrosion of reinforcing steel, and joint failure. Common materials include polyurethane, silicone, and pre-molded neoprene rubber, selected based on joint movement, size, exposure, and environmental conditions.
Proper joint preparation is critical: surfaces must be clean, dry, and free of damage. Primers are applied for bonding, and backer rods are used to control sealant depth and prevent three-sided adhesion. Non-sag sealants are tooled into place to ensure long-lasting flexibility and protection.
Additional considerations for every application:
- Concrete surface temperature, saturated moisture in the joint, dew points and varied joint widths.
- Calculation of expansion contraction movement rate
- Joint design spacing, material cure time, and compatibility with any aggressive chemicals / elements
- Depth to width ratio of sealant
- When resealing an existing joint, determine what material was originally used.
- What kind of traffic will travel over the joint
- Is a UV inhibitor coating needed?
