Aggregate Piers Systems

We design and install aggregate piers using vibratory probes (Vibro-probe or Vibro-flot) that densify the existing soils adjacent to the pier while advancing to depth, compacts the stone in lifts and pushes the stone laterally into the existing soil.   This process develops a series of high modulus stone column and while improving the existing soils between and adjacent to the columns, creating a matrix of soil to achieve the design goals of the system.  Our vibro-flots induce over 45,000 lbs of centrifugal force at a high frequency and over 30,000 lbs of downward force.

Stone columns are used to improve or reinforce poor soils to increase bearing capacity, reduce settlements, mitigation liquefaction, and stabilize soils for buildings, walls, bridges, roadways and other structures.

Each element is continually monitored and recorded by a computer during installation, providing instant data for quality control.

The use of aggregate piers often shortens the construction schedule and reduces costs when compared to over-excavation/replace more than 5 ft, or deep foundations. Aggregate piers may also eliminate the need for temporary shoring or underpinning systems, significantly reduce handling/shipping off contaminated soils, while allowing for typical spread footing construction.
