ALLU Group, Inc. has introduced the Allu 3D Positioning System, the newest addition to the Allu lineup of mass stabilization products for the geotechnical market and solidification/stabilization (S/S) in the remediation market. The new system uses GPS signals to precisely locate the Allu PMX excavator-mounted power mixing head, guiding the excavator operator to feed the correct amount of binder and to thoroughly mix each block of the job matrix.

Allu said mass stabilization or solidification is a fast and cost-effective method for strengthening soft soils by adding a binding agent into the soil to support pavement or other structures. It can also be used to mix binders or additives into contaminated soil or sediment to immobilize hazardous constituents within the treated material and thus preventing the contaminant from spreading into the surrounding areas.

The new system has four modules, including computer unit with software, touch screen, base station and GPS Sensor. The Pressure Feeder Data Acquisition System (DAC), tracks the amount of binder applied and the 3D Positioning System tracks exactly where it was applied.

The 3D Positioning System tells the operator when to change locations and begin stabilization from another point, optimizing mixing production rates, while ensuring thorough mixing, accurate binder addition rates, and efficient use of the binder.
