Concrete Repair Secrets That Professionals Won’t Tell You

Unlock the full potential of your concrete repairs by discovering the professional secrets that can transform your approach and results—read on to learn how!

Innovative Repair Techniques

1. Polyurethane Foam Injection
   • How it works: This technique involves injecting a polyurethane resin into the crack. Upon contact with water, the resin expands, filling the crack completely and sealing it against further moisture ingress.
   • Advantages: Effective for waterproofing, quick to apply, and the foam can expand to fill large voids.
2. Microbial Induced Calcite Precipitation (MICP)
   • How it works: MICP is a bio-remediation process that uses bacteria to precipitate calcite, which cements the concrete particles near the cracks.
   • Advantages: Environmentally friendly and enhances the overall strength of the concrete.
3. Flexible Concrete
   • How it works: This method involves using a flexible concrete formulation that includes polymers which enhance the flexibility of the material, allowing it to move without cracking.
   • Advantages: Ideal for areas subject to thermal expansion and contraction.
