Mudjacking or Cement Grouting

Servicing Pennsylvania, New Jersey, Delaware, & Maryland

The mudjacking / cement grouting process involves the use of a water, soil, fly ash, and cement mixture injected by hydraulic pressure into the underlying soils to void fill and support the damaged or settled areas of the asset. Unfortunately, the cementitious material is slow to cure, and, shrinks as it hardens creating new voids. Once this material cures, it lacks sufficient tensile strength for long term effectiveness.

Problems with Mudjacking / Cement Grouting

When cement grouting, or mudjacking, is used to fill subsurface voids in an effort to stabilize the asset, significant amounts of the material must be pumped into the soil to ensure the underground space is completely filled. Once this material hardens its inherent weight of 140 lbs/ft3 adds an excessive burden to an already distressed base soil condition. In addition, this added weight can also complicate adjacent utility conduits and piping located beneath the surface of the building structure. If enough force is applied, the pressurized grout can move existing utilities out of alignment or force its way into cracks that exist within the underground pipes or lines.

Mudjacking Alternatives
