Our process effectively stabilizes soils, fills voids and lifts concrete using high-density polyurethane foam.

Polyjacking | Foundation Lifting Services in Alaska

Polyseal Insulation offers an innovative, cost effective solution for homes that have experienced sinking or settling due to the 11/30 earthquake. Using a structural Geo-foam with a compressive strength rating of 10,800 lbs per square foot, we are able to lift and bed the foundation footer to restore your home to pre-quake conditions.

Foundation LiftingPolyseal Insulation offers an innovative, cost effective solution for homes that have experienced sinking or settling due to the 11/30 earthquake. Using a structural Geo-foam with a compressive strength rating of 10,800 lbs per square foot, we are able to lift and bed the foundation footer to restore your home to pre-quake conditions.

The process is simple - for homes with daylight basements and buried footers, we use our rubber tracked mini excavator to dig down and expose the foundation line.

From that point, hydraulic jacks are installed around the perimeter so the structure can be raised in a smooth, steady sequence.

Once the structure has been lifted back to level, port holes are drilled down at an angle to the center of the footer and the structural foundation foam is injected through these.

The Geo-foam spreads and reacts, filling underneath the foundation to support the weight of the home. The foam is designed to inject and fill down into any cracks, loose areas or fissures far below the soil line of the foundation, resulting in a massively strengthened and bedded section of ground beneath the home that significantly reduces chances of any future settling.

Cure time is only a matter of 15 minutes, so as soon as the home is structurally bedded, the jacks can be removed and backfill can commence.

For homes on a traditional crawlspace, we can generally lift entirely from inside which can significantly reduce cost and invasiveness since no exterior excavation is required!

In certain circumstances, the injection of two-part expanding polyurethane foam (or similar chemical foam material), also known as foam stabilization, can be used to mitigate soil liquefaction by creating a foam matrix within a liquefiable soil; which reduces the soil’s ability to liquefy during future seismic events by displacing pore water and locking individual soil grains into a non-mobile foam medium. Foam injection can also be used to fill subsurface voids and/or level floor slabs, pavement surfaces, etc.

Foam injection/stabilization is generally the least disruptive foundation repair approach, as no excavation is typically required to expose the foundation and foam injection equipment is portable and easy to maneuver into tight spaces; which makes it an ideal application for projects where foundation access is limited; such as interior footings or areas with congested underground utilities, etc. The capability of foam injection to raise (i.e., re-level) foundations is limited, however, by the relatively low pressures at which foam is injected. As such, foam injection is typically only used to re-level foundations which are subjected to relatively light bearing loads and which require relatively small amounts of vertical adjustment.
