Brief overview of top-feed Vibro Pier™ installation. Vibro Piers™ also known as aggregate piers, are typically installed to intermediate depths of 5 to 20 feet for the support of new loads. Suited for light to heavy loads, on large or small projects, Vibro Piers are quick to install and very effective at reinforcing the surrounding soil. Vibro Piers reinforce the ground to increase bearing capacity, reduce settlement, increase global stability and decrease seismic deformations. Vibro Pier technology utilizes a powerful down hole vibrator to compact select aggregate in lifts. The vibratory energy and ramming action of the vibrator causes the dense aggregate to interlock and form a stiff pier that engages the surrounding soil, providing reinforcement and increased shear resistance.
