Expansion, Control, and Crack Rehab
Crack, Expansion, and Control joints for concrete walls, foundations, slabs, and footings
Expansion and control joints are used in concrete walls, foundations, slabs, and footings to allow for movement and expansion of the concrete due to temperature changes and other factors. These joints can become damaged over time, requiring repair to maintain the integrity of the structure.
When concrete structures age it is highly likely to see small hairline cracks begin to form due to a number of environmental reasons - most are due to temperature change and moisture.
The process of repairing cracks, expansion and control joints on concrete using polyurethane resin involves the injection of the resin material into the joint to fill in any gaps or damage. The resin is injected through small holes that are drilled into the joint, and it then expands and hardens, filling in any voids and restoring the integrity of the joint.
One advantage of using polyurethane resin for this purpose is that it can be injected through small holes, making the repair process non-invasive. It is also very strong and durable and can withstand the forces that are placed on the joint or crack.
The Magic Poly Solutions process of repairing cracks, expansion and control joints with polyurethane resin begins by drilling small holes into the joint at the location where the resin is to be injected. The holes are spaced about a foot apart and are typically about the diameter of a pencil.
Next, the resin material is mixed and injected into the holes using a specialized injection system. The resin material is usually a one-part system that consists of a foaming agent. When the urethane contacts water, it expands and harden, filling in any voids and restoring the integrity of the joint or crack.
Structural concrete cracks are repaired by using our epoxy resin injections or resin gel materials based on situational needs.
Overall, using urethane or epoxy resin to repair cracks, expansion and control joints is a quick, effective, and durable way to restore the integrity of these important structures.
