Polyurethane Injection Technology

Polyurethane Slabjacking for Concrete Raising

Polyurethane Slabjcking for a warehouse floor. Floor measurements are taken as part of the process.

Polyurethene Slabjacking is the latest technology for concrete repair.  Polyurethane injections provide all the same advantages of traditional slabjacking, but with new and greatly improved featuresIncluding it's high strength, rapid set time, and light-weight properties, polyurethane grout is revolutionizing the industry.  The material is vastly superior to traditional cement grouts and provides better results for clients.   

High density polyurethane foam provides all the benefits of traditional slabjacking materials, but with new and improved physical characteristics. These benefits include:

  • Less Construction Time: Polyurethane slabjacking work generally takes a fraction of the time required for most concrete replacement work. It is also faster than traditional slabjacking, especially for projects where large quantities of material is required.
  • Fast Set-Up Time: Polyurethane generally reaches ninety percent strength within 15 minutes from initial injection. This benefits is greatly realized for sites that experience heavy traffic load, especially for warehouse floors and concrete roads. Once a highway slab is lifted with polyurethane, it can be driven on almost immediately.
  • Lightweight Properties: Polyurethane foam is extremely lightweight. When lifting concrete over soft soils, polyurethane foam will minimally overburden the existing subsoil, greatly limiting future settlement.
  • Less Impact: High density polyurethane foam requires significantly less clean-up when compared to traditional slabacking. This is greatly beneficial for sites containing operations sensitive to dust and construction debris.
  • High-Strength: Polyurethane grout can achieve compressive strengths in excess of 100 psi within minutes. This high-tech material is much stronger than traditional slabjacking grouts.

Polyurethane slabjacking is a highly versatile process and is eco-friendly.  Polyurethane foam also provides economical alternatives for repairing our aging infrastructure. It has a wide variety of applications, including:
