August 11, 2011 MOUNT AIRY, NC—Gary Molstre, owner of Mudpumpers Mudjacking, Moorehead, MN, says there is no chance they are changing the company name, but they are definitely changing the material they use to repair highways and bridges to an engineered polyurethane foam system and they’ve coined a term for it: “foamjacking”.
Mudjacking, also called slab jacking, concrete lifting, concrete raising, and slab leveling, is the traditional method of fixing damaged concrete highways and bridge approach panels. The process was developed in the 1930s and involves pumping “mud” (everything from clay, sand, and loam, to Portland cement, fly ash, lime, casting plaster, and hot asphalt have been used) beneath concrete slabs that have become uneven, sunken, and/or pulled away from bridge approaches due to soil erosion and/or the soil being compacted or compressed from the sheer weight of the slab. Mudjacking involves drilling holes in the concrete and pumping “mud” and pressure beneath to lift the slab to its original place and keep it there.
