SEALBOSS SLABLIFTING ICONSealBoss Slab Lifting Foams, Pumps, Systems

Slab Lifting with polyurethane concrete jacking foam for the purpose concrete slab leveling is also known as Polyjacking and Foam Jacking. Concrete slab lifting is achieved by injecting SealBoss structural polyurethane concrete lifting foam into voids beneath settling or uneven concrete slabs with the purpose of support and lift. Polyjacking is a proven concrete leveling method to stabilize, void fill and provide foam concrete lift without excavation and without adding much additional weight to the substrate.

Existing concrete slabs indoors and outdoors can be lifted or foam jacked to their original position utilizing the SealBoss Slab Lifter System and expanding concrete jacking foam products.

The process of slab jacking, foam jacking, polyurethane concrete raising, poly jacking or poly leveling uses chemical grouting techniques and chemical polyurethane grouts and offers many advantages over conventional mud jacking.

Foam jacking is used in industrial and residential markets.

Foam jacking is the cleanest and fastest concrete lifting and stabilization process. Only very small port holes are required. Drilling is clean and fast due to the small diameter hole size.

Foam jacking is the quietest and fastest process for stabilizing and raising settled concrete slabs.

Lightweight high strength, high density polyurethane foam reduces the overburden on underlying soils, reducing the chances for re-settlement. High density polyurethane is waterproof, so treated slabs are thoroughly undersealed and protected from washout.

Advantages of chemical grouting for slab lifting and stabilization:

  • Quick and easy process with minimum mess and inconvenience
  • Minimal invasive, very small port holes to inject product through slab
  • Minimal disruptive
  • Low unit weight, easy to transport to jobsite
  • Stabilizes base and strengthens slab Combine with subgrade soil stabilization for permanent results
  • Erosion control
  • Less costly than replacement
  • Based on scope work can be done in hours/days
  • Quick set time

SealBoss ® Deep Soil

Soil Compaction, Void Fill, Slab Lift Injection System

DeepSoil Lift™ Aplications:

Soil densification and encapsulation

  • Settled buildings, warehouses
  • Pipe and tunnel segments
  • Bridge abutments
  • Highway approach slabs
  • Concrete, rigid and flexible pavements
  • Ports, airports, bus stations
  • Lift stations
  • Equipment pads

When Slab Lifting is not enough:

DeepSoil Lift™ (DeepSoilLift.com) is a polyjacking / foam jacking polyurethane foam injection system process utilizing a SealBoss injection pump and injection lance setup to reach deep into the soil to below grade pockets of unstable soil up to a depth of 30 feet (10 meters) with the purpose of densification and compaction.

The DeepSoil Lift™ process is useful for certain structures and flexible pavements where it can be applied in conjunction with conventional slab lifting.

A thorough site evaluation prior to injection is recommended. This may include soil borings, Dynamic Cone Penetration (DCP) testing, Ground Penetrating Radar or Structural Radar (GPR) as necessary. Based upon data, grid spacing and injection depths are determined. Install SealBoss Injection Lances to the correct locations and depths. Inject with SealBoss 1600 series structural foam polymer monitoring for lift, pressure and consumption.
