A sinking or uneven foundation is a very serious problem that can have a huge negative impact on the value of your home. The problem usually features early warning signs such as minor cracks in the foundation walls. These can be vertical, horizontal, or stair-step cracks. Minor cracks should not be ignored. More serious indicators would be cracks open more than ¼”, as well as sticking windows, doors, and cabinets. These symptoms indicate that the house is definitely on the move.

How We Repair

The service to fix a sinking or uneven foundation would involve URETEK Deep Injection® (UDI) of our polymer resin under the affected areas. We typically inject directly under the foundation at two depths to densify the soils. Where levelling is required, we inject enough polymer resin to lift the structure back to grade. Then, based on the original condition of the home and the process we used to address the problem, will typically provide the homeowner with a guarantee.

Have Any Questions?

Our proven UDI application is also the preferred method for stabilizing weak soils and lifting settled parking lots and paved public spaces.

The UDI Advantage


UDI requires no excavation, and projects can often be completed in hours or days. Traditional repair methods often involve excavation, and the time required for project completion can be weeks.


The repair process is priced consistently below alternative repair methods, and implementing repairs now significantly reduces further repair costs down the road.


URETEK’s 486 Star polymer is specially formulated for stability and strength, even in the harshest environments. Our polymer is hydro-insensitive, and UDI is warranted against loss of dimensional stability or deterioration.


URETEK’s 486 Star polymer material has been used to successfully complete over 100,000 projects nationwide. The lightweight, expansive geo-polymer material not only realigns concrete pavement but also addresses the problem at the source – weak soil composition – giving customers a long-lasting solution.

Minimally Disruptive

Unlike other repair methods, UDI is minimally disruptive and requires no excavation.


Liability risk is greatly reduced with UDI due to an inherently safer working environment without deep excavation or heavy equipment. The process and material are eco-friendly and meet today’s high environmental standards.
