Polyurethane Injection

Introduction

Polyurethane injection, often called “slabjacking” or “mudjacking,” is a non-invasive concrete leveling method that restores sunken concrete slabs to their original level. It is typically used to repair sidewalks, driveways, patios, and other concrete surfaces. The procedure involves injecting a lightweight polyurethane foam beneath the concrete, which expands to fill voids and lift the slab.

Advantages of Polyurethane Injection

Polyurethane injection offers several advantages over traditional concrete leveling methods:

  • Non-Invasive:
  • Polyurethane injection requires no excavation or concrete removal, minimizing disruption to your property.

  • Fast and Efficient:
  • Injections can be completed quickly, with minimal downtime for your concrete surfaces.

  • Cost-Effective:
  • Polyurethane injection is often more cost-effective than traditional repair methods, as it reduces labor and material costs.

  • Durable Solution:
  • Polyurethane foam cures into a strong, lightweight material that provides long-lasting support and stability.

  • Environmentally Friendly:
  • Polyurethane foam is non-toxic and does not release harmful chemicals into the environment.

Steps Involved in Polyurethane Injection

The polyurethane injection process typically includes the following steps:

  • Drilling Injection Holes:
  • Small holes are drilled into the concrete at strategic locations to allow for foam injection.

  • Foam Injection:
  • Polyurethane foam is injected through the holes using specialized equipment.

  • Foam Expansion:
  • The foam expands and fills the voids beneath the concrete, lifting it to its level position.

  • Finish Leveling:
  • Once the foam has cured, the holes are sealed, and any excess foam is trimmed.

Conclusion

Polyurethane injection is a reliable and effective method for concrete leveling and repair. Its non-invasive nature, speed, cost-effectiveness, and durability make it an ideal solution for restoring sunken concrete surfaces without major disruptions. If you are experiencing issues with uneven or sunken concrete, consider the advantages of polyurethane injection to regain the functionality and aesthetics of your concrete surfaces.
