No, standard consumer-grade aerosol spray foam (such as Great Stuff) completely lacks the compressive strength, structural density, and load-bearing capacity required to lift heavy concrete slabs. Attempting to use household insulating foam beneath concrete will result in the foam crushing instantly under minimal weight, trapping moisture, and decaying rapidly. Professional concrete lifting requires high-density engineered geotechnical polyurethane foam.
