Concrete Repair

Weathering, freeze/thaw, mechanical loading, seismic events, chemical exposure and corrosion of embedded reinforcing steel are common causes of concrete deterioration.

CRI provides a variety of long-term concrete repair utilizing the most effective procedures available.

• Spall & Crack Repair
• Patching & Grouting
• Structural Concrete Repair
• Structural Strengthening

Epoxy Pressure Injection (Crack Repair)

Epoxy injection is a permanent structural and preservation procedure. The epoxy injection process not only fills cracks, but welds them together structurally with an epoxy material that’s forced through cracks under pressure forming a bond that’s stronger than the concrete itself.

Quality of workmanship in epoxy injection is critical because no one can see if a crack is completely injected. Critical job site considerations include proper surface preparation, method of capping and porting, injection material, applied method and confirmed results.

CRI has the training, equipment, and experience to perform your unique injection application. Vertical, horizontal, overhead applications, class A to class D cracks, resins or gels, and low or high-pressure injection work are just a few of the pressure injection options available.

Crack Sealing & Filling

Semi-Rigid Epoxy, Polyurea & Polyurethane Joint Filling

Cracks in concrete can be caused by deficiency in design, construction and neglect. Over time and exposure to the elements, these cracks can worsen. Prolonging the repair of these cracks will only make repairs more costly and more extensive.

Cracks in concrete exposed to moisture should be repaired as quickly as possible to avoid extensive damage, which leads to more costly repairs.

Routing and sealing is the most common method of crack repair. In this procedure the crack is enlarged to permit sufficient penetration of the repair compound. This method is most effective when the material is installed into the crack to prevent further damage of the concrete substrate.

Concrete Resurfacing

CRI offers concrete resurfacing for a variety of flooring solutions.

All floors designated to receive self-leveling cement are mechanically prepared to establish an adhesion profile. The material will be mixed in a twin hopper batch mixer, and pumped to the floor. Once applied, the self-leveling cement is pulled smooth and allowed to dry.

Pre-fill may be required prior to the placement of self-leveling cement. The finished product may be coated, tiled, carpeted or enhanced in its existing state with staining, polishing or sealing.

Some resurfacing options include:

• Self-leveling Underlayments
• Self-leveling Topping
• Decorative Toppings
• Stampable Overlays
