Impingement Style Polymer Foam Application Gun

Equalizer polyurethane foam gun


  • Concrete leveling – slab jacking
  • Void filling
  • Soil stabilization


  • No O-rings
  • Versatile – Three injector sizes for various viscosity materials and ratios
  • Quick and easy maintenance
  • Button head port connection system for soil grouting applications
  • Screw-on port for concrete leveling, slab lifting applications

Conventional impingement guns do not like back pressure. Too much back pressure and the gun crosses over, resulting in labor intensive gun rebuilds, down time, replacement parts and, in some cases, lost hoses. Back pressure at the spray tip is inherent to leveling slabs, void filling and soil stabilization.

The Equalizer gun is the only impingement gun engineered to handle back pressure induced when conveying two-component polyurethane foam to lift slabs, fill voids and stabilize soils. Aside from the actuation valves, this gun has no internal moving parts and NO O-rings, which makes maintenance quick and inexpensive.

Do you spend hundreds of dollars a year on replacement parts for other guns? Do you lose hours of work time rebuilding, repairing or replacing your existing gun? Do you spend hundreds of dollars on injection ports? If so, the Equalizer is the answer.

The Equalizer gun is compatible with all hydraulic, pneumatic and electric proportioners.

A small electric airless sprayer like the Titan Advantage 100, Titan Impact series or similar sprayer is required to pump flush water to the gun head.
