Concrete Raising with Polyurethane Slabjacking in Ansonia, CT
The Challenge
The concrete floor of a ten-year-old residential home had settled more than three inches, creating uneven surfaces and structural concerns. Further investigation revealed a significant void beneath the slab, with exploratory drilling confirming void depths of 3 to 4 inches in multiple areas. Left unaddressed, the settlement risked continued movement and further deterioration of the concrete floor.
Project Considerations
A full slab removal and replacement would have been disruptive, time-consuming, and costly for the homeowner. The repair needed to be completed quickly, with minimal disturbance to the residence, while effectively addressing both the slab settlement and the underlying void.
Our Solution
Engineered Foundation Technologies utilized polyurethane slabjacking to raise and stabilize the sunken concrete floor. A series of small, strategically placed holes were drilled into the slab, allowing high-density polyurethane foam to be injected beneath the concrete.
The expanding foam first filled the existing void space, then continued to lift the slab back toward its original elevation through controlled, precise grouting.
Results & Benefits
The project was completed in a single day with minimal disruption to the home. In addition to restoring the slab elevation, the homeowner experienced added thermal benefits. Due to its high R-value, the polyurethane foam provided insulation beneath the slab, helping reduce heat loss and improve indoor comfort during the winter months.
