  • Seal or grout plastic or steel casing
  • Isolate screen intervals, subsurface instrumentation, and sampling zones
  • Provide a protective interface between gravel pack and cement grout
  • Plug abandoned earthen boreholes and cavities
  • Create a stable, permanent, low permeability below-grade seal in:
       - monitor/observation wells
       - dewatering holes
       - caisson holes
       - soil sampling holes
       - mineral exploration holes
       - water wells
