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.
Repair scope
Spall & Crack Repair
Patching & Grouting
Structural Concrete Repair
Structural Strengthening
Crack Sealing & Filling
Routing and sealing is the most common method of crack repair: the crack is enlarged to permit sufficient penetration of the repair compound.
Semi-Rigid Epoxy, Polyurea & Polyurethane Joint Filling
Epoxy pressure injection
Epoxy injection is a permanent structural and preservation procedure. The epoxy is forced through cracks under pressure, filling them and welding them together structurally with a bond that’s stronger than the concrete itself.
Quality of workmanship 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.
- Vertical, horizontal and overhead applications
- Class A to class D cracks
- Resins or gels
- Low or high-pressure injection
Concrete resurfacing
All floors designated to receive self-leveling cement are mechanically prepared to establish an adhesion profile. The material is mixed in a twin hopper batch mixer and pumped to the floor, pulled smooth and allowed to dry. Pre-fill may be required. The finished product may be coated, tiled, carpeted or enhanced in its existing state with staining, polishing or sealing.
- Self-leveling Underlayments
- Self-leveling Topping
- Decorative Toppings
- Stampable Overlays
