Geotechnical Construction Overview

We have done everything from putting out mine fires to filling up sinkholes and helping the Pennsylvania Turnpike give everyone a smoother ride. Along the way, Howard Concrete Pumping has built a reputation for results, cost-savings, and customer service that is secondto- none.

In recent years, we have completed more than 100 geotechnical construction projects. These projects have involved drilling more than 16,000 boreholes, with more than 1,250,000 lineal feet of drilling, in diverse geological conditions. We have batched and placed more than 750,000 cubic yards of grout to solve a variety of geotechnical problems. Some of our successful projects include: mine stabilization, permeation grouting for drainage control, compaction grouting, and micro pile installation.

Our projects range in size from $10,000 to over $10,000,000, and includes these services:

  • Mine Stabilization
  • Mine Fire Mitigation
  • Compaction Grouting
  • Micropiles
  • Shotcrete
  • Temporary and Permanent Tieback Anchors
  • Soil Nails
  • Soil Mixing

Our professional staff includes geologists and engineers that collectively have more than 150 years of experience in the geotechnical construction industry. See for yourself why putting our Company to work for you means one less thing to worry about.

Soil and Rocks Anchors

Soil and rock anchors have been used successfully for decades in both temporary and permanent applications. Typical uses are for retaining walls, dam stabilization, excavation support, marine bulkheads, and landslide stabilization.

Anchors are installed by drilling to the appropriate depth in the soil or rock, setting steel strand or bar material in the borehole, placing cement grout, then stressing the anchor to the required load using a hydraulic jack. Anchor loads in excess of 1,000 tons have been reached with rock anchors.

Micropiles

Micropiles are small diameter (less than 12 inches) drilled-in support elements. Micropiles often are constructed using high strength steel pipe (80 ksi) and can provide compression load capacities in excess of 400 kips using 9-5/8-inch diameter pipe. Micropiles can be installed in restricted workspaces - low headroom, tight areas and tough access locations. They can be used for new foundations or to supplement existing foundations.

Retaining Walls

Structural walls are constructed to support vertical changes in grade for either permanent or temporary conditions. These walls can be soldier pile/lagging construction, or soil nail/shotcrete construction.

Flowable Fills

Our combination of drilling and grouting expertise has made us the leading choice of contractors, mining companies, government agencies, and communities faced with solving mine subsidence problems. We have also made flowable fills for other purposes, such as trench and excavation backfill, foundation support, and pond liners.

Soil Mixing

Soil mixing operations are used to stabilize coal refuse ponds and hazardous waste impoundments by the introduction of cementitious material. Deep mixing is conducted by utilizing a specially designed three auger mix panel supported by a large capacity crane. Shallow mixing is accomplished by using a custom designed large backhoe equipped with a long reach dipper stick and hydraulically driven mixing device.

Drill & Grouting

Many applications of drilling and grouting exist. Two specialty applications performed by us include Permeation Grouting and Compaction Grouting. Permeation grouting is the placement of a grout material, cementitious or chemical, into voids in the soil or rock strata. This can be accomplished by either tremie or pressure grouting methods. Compaction grouting is the placement of a low slump, low strength material under pressure into loose soil strata for ground improvement purposes.
