Highway LiftRoads and Highways, Infrastructure Repair, Bridge Approaches

Polyurethane foam injection is widely used with municipalities and DOT’s to lift and level concrete roadways, highways, and bridge approaches, as well as repair transverse cracking in asphalt streets, and stabilize poorly compacted soils. The foam used for such applications, is very dense foam, which may have lifting capacities of approximately 6000 lbs per sq. ft, and capable of leveling loads as high as 120 tons in a surface area of less than 900 sq ft. The slabjacking performed on such projects not only may lift and level the structures, but will also underseal and stabilize the soil.

Once the foam is injected, and the repairing process is completed, vehicles can immediately drive over the area where the work has been completed.

Benefits of Using Foam Injection:

  • Cures in 15 minutes – which highly reduces traffic control
  • Yields 100 psi in 15 minutes
  • Requires small 5/8" holes
  • Foam underseals and stabilizes soil
  • Very lightweight
  • Will not break, crack or deteriorate
  • Will not be effected by moisture
  • Creates a water tight seal to solid surfaces
  • Will lift heavy slabs of concrete

Residential Repair

residentialTrip Hazard, Sidewalk Repair, Walkway Repair, Concrete Raising

Settled concrete generally create a vertical displacement, which is a huge liability, not only for municipalities, but for residential, commercial, and property managers alike. Slabjacking concrete sidewalks with a polyurethane foam injection will lift and level the concrete, while also preventing the sidewalk from further settlement. The foam will prevent from further settlement, making a more permanent repair, which is a much better option than the traditional mudjacking or grinding.

Cost to complete this service is very comparable to grinding, but with better results.

Benefits of Using Foam Injection:

  • Cures in 15 minutes
  • Yields 100 psi in 15 minutes
  • Requires small 5/8" holes
  • Foam will travel, filling in all voided area, which requires less holes to be drilled
  • Interacts with the soil, stabilizing it
  • Very lightweight
  • Will not break, crack or deteriorate
  • Will not be effected by moisture
  • 10 year warranty
  • Creates a water tight seal to solid surfaces
  • Will lift heavy slabs of concrete
  • Used in a broad range for repair

Commercial Repair

BeforeAfter1aWarehouse Floor Repair, Joint Stabilization, Void Filling, Sub Surface Void Filling

When soil is not properly compacted, experiences erosion, or heavy machinery weaken the sub grade, voids appear underneath the concrete surfaces. Unfortunately, many times, these voids are often unforeseen, and cause further damage to the surfaces. If indications provide that such problems exist, foam injection is a great alternative in filling in the voids, creating a strong support to the existing surfaces.

Polyurethane foams to make such repairs are a lightweight, high dense foam, which reacts slower than the foams used for lifting and leveling concrete.

Soil Stabilization

mudjacking materialConcrete Lift & Stabilization also provides the service of stabilizing soils. We use a product which we recognize as a Soil Binder. The stabilizer is low viscosity single component polyurethane, designed to bind and stabilize loose soils. When the binder is pumped into soils, it reacts gathers the loose soils, and hardens in a manner that strengthens the injected areas. Soil Binder has been used to stabilize concrete floors, foundations, and helical anchors.

Results:

The results of pumping it into soils are a function of saturation, soil type, compaction, and moisture. Test results vary from 700 psi up to 3,000 psi. Unique Advantages:
  • Single Component
  • Contains no TDI
  • Cure time 2 hours (pending on the moisture within ground)
  • Very low Viscosity
