Concrete Restoration Conventional concrete restoration of settled concrete flatwork requires saw cutting, removal and disposal of the concrete, leveling the subgrade with a granular base, reforming and replacing the concrete flatwork. In addition, the adjacent landscaping and/or pavement requires rehab. This procedure normally takes several days to complete and is dependant on weather conditions.Alternatively a typical settled concrete section can be slab jacked in 20 to 40 minutes. In most cases the section can be returned to service upon completion. This significantly reduces any inconveniences to the site residence. Also there is little or no disturbance to adjacent structures or landscaping resulting in less environmental impact. Because of the reduced down time and little or no rehab to adjacent structures, slab jacking of settled concrete flatwork has proven to be an economical, viable alternative to removal and replacement. |

Void Filling Abandoned Underground PipesWith an increase in infrastructure upgrades, the presence of abandoned underground pipes has become more prevalent. This can pose problems such as:
Concrete Slab Construction Joints As a result of edge curl at construction joints in concrete floor slabs, minor void spaces will occur along the joint interface. With continued wheel loading, the slab will begin to pump at these joints. This pumping action will create a larger void space and eventual slab distress. Geo Grout has addressed this problem by pressure grouting the void beneath the joint. This process restores the bearing surface of the subgrade and locks the construction joint together. By addressing this problem at an early stage, the potential for slab failure is significantly reduced. Structural Steel Pipe Columns and Heavy Equipment Base Frames High strength structural grouts used for fill of structural steel pipe columns and base frames for heavy equipment installations are typically supplied as a bagged product and hand mixed on site. Geo Grout can produce mix and place larger batch quantities in the field ensuring uniformity in the grout mix. This can prove to be economical on projects which require larger volumes of these structural grouts. |

Soil Stabilization Compaction GroutingIn areas of deep trench settlement, a roadway is typically maintained with periodic asphalt patch overlay until no further settlements are evident. This may extend over a number of years resulting in ongoing hazardous conditions, as well as traffic interruption during the maintenance period. By utilizing compaction grouting techniques, the trench fill zone is stabilized, reducing the potential for continued settlement and hazardous conditions. This form of soil stabilization can prove to be a cost effective method of roadway maintenance. Consolidation/Curtain Grouting Excavation within granular materials generally requires cutbacks of the excavation walls at a 1 to 1 slope. In confined areas, this can lead to undermining of concrete sidewalks, asphalt pavements and adjacent structures. This will result in unsafe conditions and/or extensive rehab costs. Consolidation grouting, prior to excavation, can substantially reduce excavation cutbacks by stabilizing these insitu granular materials, resulting in a safer excavation and reduced overall rehab costs. |

Fluid Cut-off Sewer SystemsGroundwater migration into sanitary manholes and sewer lines increases the overall effluent levels, resulting in increased sewage treatment costs. In cases where this flow cannot be restricted due to head pressures and/or access availability, pressure grouting from the outside of these structures may be the most viable alternative for stopping the flow. Geo Grout has successfully used this technique to curb the flow of groundwater into sewer systems and other underground utilities. Earth Bores With an increase in horizontal boring operations, augering beneath earth dams and canals to accommodate pipelines has become quite common. This augering process can cause disturbances in the earth dam or canal berm, which may lead to piping of water from the structure. Geo Grout has addressed this problem by pressure grouting the annular space between the pipeline and the earth bore, utilizing micro fine mixes that seal off ground fissures, preventing water intrusion and subsequent water erosion. |
