Concrete Raising - Walgreens Store in Boston, MA

August 5, 2012

Slab Settlement:  The concrete surface pitched in various directions and was pulling away from the finish work.   It was believed that a broken utility line eroded the soil out from underneath the floor, allowing the concrete above to settle.   As the area was within a busy convenience store, a typical replacement approach would have been greatly inconvenient to the facility.  

EFT Solution:  Polyurethane foam injections were performed to raise the settled concrete.   A lightweight foam was injected through penny-sized holes in the floor.  The liquid polyurethane expanded to over 1000% of original volume, effectively lifting floor from below.  The concrete raising work took three days to complete.
