Concrete Repair & Construction Chemicals

Cracks in concrete are not always a sign of failure — concrete is a material that is designed to crack, and the cracks are controlled by the reinforcement and the joints. But when the cracks are wide, when they are growing, when they are letting water in, or when the concrete is spalling and the reinforcement is exposed, the structure needs attention. The longer the problem is left, the more the water and the chlorides will attack the reinforcement, and the more expensive the repair becomes.

The first step is to understand why the concrete is cracking. A crack can be caused by shrinkage, by thermal movement, by overloading, by a failure of the substrate, or by corrosion of the reinforcement. Each of these causes requires a different repair, and repairing the crack without addressing the cause is a waste of money. We inspect the concrete, we measure the crack widths, and we determine the cause before we recommend a repair.

For structural cracks, we use epoxy injection. The epoxy is injected into the crack under pressure, and it bonds the two faces of the crack together, restoring the structural integrity of the concrete. For cracks that are moving, we use a flexible polyurethane that can accommodate the movement without cracking again. For spalled concrete, we remove the loose material, clean and treat the reinforcement, and rebuild the section with a repair mortar that is matched to the strength of the original concrete.

We also supply and specify the construction chemicals that are used in new concrete — the admixtures that make the concrete more workable, the bonding agents that make repairs stick, and the curing compounds that make the concrete stronger. These are the products that are used in the repair and in the new construction, and they are specified by our technical team to match the exact requirements of the project.

The result is a concrete structure that is repaired, protected, and documented.

We give you a written specification of the repair, the products that were used, and the reason for the repair. The concrete is not just patched — it is fixed, and it is fixed in a way that will last.
