Raise-Rite Concrete Lifting is one of the few companies to offer both slabjacking and polyurethane foam lifting options. Both methods accomplish the same results, our experienced estimators can inform you of the best application for your concrete lifting needs.
Mudjacking utilizes a sand-cement grout comprised of Portland cement and baseball sand. The grout is pumped beneath the slabs, under pressure, to raise the sunken slab. Mudjacking material weighs about 100# per cubic foot.
Polyurethane Concrete Lifting uses a 2-part, high-density foam which is injected beneath the slab. The foam expands beneath the surface filling voids and raising the concrete. The material does not lose its density. Polyurethane material is lightweight at approximately 2# per cubic foot.
Drill Holes – Injection Holes
After the slabs are raised the holes need to be patched. Holes are noticeable due to putting fresh concrete patch on aged concrete. Mudjacking holes are about 1 5/8″ in diameter, while foam jacking holes are only about 5/8″. The comparison would be a golf ball size hole to that of a dime.
Raising concrete is significantly more economical than replacing concrete. Concrete raising is typically 1/2 of replacement costs. Traditional mudjacking costs less than polyurethane raising. Polyurethane material itself is more expensive. However, due to the smaller hole size, lighter material weight and hydrophobic nature, polyurethane concrete raising is an attractive option for specific projects.
