Soil Grouting and Ground Improvement Specialists

 

         

Moore & Taber offers a diverse spectrum of ground treatment options and geotechnical construction services.  We are licensed in Arizona, California, Nevada, Oregon, Utah and Washington.  Please click on a link to the left of this page for a description of each specific service that Moore & Taber provides.  Listed below are some of the general applications to which we typically apply our specific remedial services.

Structure Support

Soft, weak, expansive or moisture-sensitive foundation soils can contribute to poor support of the overlying structure.  Structural support can be enhanced, either by strengthening those supporting soils with compaction grouting methods, or by transferring structural loads to deeper soil strata or bedrock.  The latter approach can be addressed with one or more of several underpinning methods, including pipe piles, pin piles, caissons, deepened footings and grade beams.  An accurate diagnosis of the specific soil/foundation problem is critical in applying the proper approach.

Structure Releveling

Given the wide variety of buildings and soil conditions it is not uncommon for some structures to exhibit a "tilting" or "warping" effect.  In many instances this effect can be rather pronounced, with potentially damaging stresses imparted to the building's framework.  Restoring such a structure to an improved relative elevation reduces that stress, and improves the aesthetics.  Relative elevation differential can be measured with a manometer, or similar device, and plotted on a floor plan to provide the geotechnical design professional with useful diagnostic information.  Proper diagnosis of the problem is paramount to applying the proper repair.  Moore & Taber can apply a number of releveling solutions, including compaction grouting (often referred to as "mudjacking"), mechanical jacking, and subsealing.

Liquefaction Mitigation

With the ever-increasing population density in coastal regions of the Western United States and subsequent demand for new and upgraded infrastructure elements, commercial structures, residential structures, schools and hospitals, the problem of liquefaction potential has become a key consideration in the planning process.  Conventional soil mitigation measures, such as removal and recompaction, are not always practical or cost effective for this application.  Consequently, alternative methods of ground treatment, including compaction grouting and dynamic compaction are often specified.  These techniques allow for augmentation of soils at depth without the costly excavation procedures typical of those applied in densely-developed areas.

Mitigation of Raveling Sands

Clean sands do not stand well when excavated.  They tend to ravel, and seek a relatively shallow angle of repose.  The soil conditions associated with these deposits can be problematic when excavating utility or footing trenches, or when encountered during the tunneling process.  Permeation grouting and chemical grouting techniques have been successful in addressing these types of problems.

Hillside Repair

Heavy rains, saturated ground, loss of lateral support, and unfavorable ground conditions are but a number of factors that may contribute to hillside instability.  Many hillside failures are shallow, occurring in a water-saturated slope face, and can result in local slumps and mudslides.  Some slope failures are termed "landslides", and typically result from deeper-seated problems involving adverse bedding or other unfavorable geologic discontinuities.  Other instability problems can occur in areas of steep bluffs where active erosion can hasten bluff retreat.

Moore & Taber can provide methods and manpower to address a variety of hillside repair projects.  Our personnel and equipment are specialized to the type of limited-access environments that are often required for such repairs.
