Grouted Micropiles

Grouted Micropiles

Grouted micropiles are a drilled, 2-part deep foundation system (up to 200 feet) with 5-12 inch shafts. Grouted micropiles are made up of steel casing, rebar, and grout. They are suitable for areas where ground conditions are less than ideal, including limited access, obstructions (natural or man-made), and problematic soil. Micropiles can be used on a variety of projects, including the fortification or creation of foundations for bridges, towers, and new buildings. Their versatility has led to their increased popularity and use in complicated construction conditions.

Grouted micropiles have high axial and lateral load capacity and transfer the structure’s load to soil that can support it. Applications include – but aren’t limited to – structures with failing foundations, seismic retrofitting, and support for structures experiencing problems due to adjacent construction. Since loads are typically achieved through skin friction between the cement grout and surrounding soil or rock, micropiles can be built to handle high-capacity loads.

Advantages

  • Greater Load Support

Pressure grouted piles can have significantly greater maximum load capacities than non-grouted piles.

  • More Locations

By utilizing grout, this allows more consistent load capabilities in a variety of soil conditions.

  • Lower Noise Levels

Installations are quiet and produce minimal vibrations, making them ideal for projects in urban and sensitive areas.

  • Environmentally Friendly

These piles have minimal effect on the terrain, environment, and wildlife, making them a green foundation option.

  • Minimal Site Disturbance

Typical pile installation produces no soil cuttings. The jobsite is often more cleaner and more optimized.
