N.J. – The ALLU Stabilization System consists of three components that increase
the strength and dynamic stiffness of soft soil, which improves its engineering
characteristics and remediates contaminated soil.

The first component is the
ALLU PMX Power Mixer, a hydraulic accessory for excavators that mixes up to 23
feet deep. The second is the ALLU PF Pressure Feeder, which injects the binder
agent via hoses into the ground. The third component is the ALLU DAC Data
Acquisition Control System, which measures, controls and provides data during
the stabilization project.

The mass stabilization
method used by the ALLU Stabilization System is a quick, cost-effective and
environmentally friendly solution that improves soft soils by mixing binder
into clay, peat, mud or dredged sediments in comparison to traditional methods
of piling or soil replacement. It can also be used in treatment of contaminated
soils by encapsulating contaminants within the ground and preventing migration
to the surrounding areas.

The ALLU PMX Power Mixer handles
various difficult materials like clay in different forms, peat, sludge, mud and
contaminated soil. It penetrates through hard crust layers and mixes the soils
effectively based on the intelligent positioning of the drums. The drums rotate
and mix material in a controlled way in all three different directions simultaneously,
while the conical binder nozzle efficiently spreads binder. The hammers on the
mixing drum are changeable and the straight one-piece binder tube is
maintenance-friendly. The power mixer is equipped with automatic torque
adjustment on the hydraulic motor, gearbox temperature indicator and drum
rotating speed indicator to ensure effective job site control. The PMX 500
model mixes up to 16.5 feet deep and the PMX 700 model mixes up to 23 feet

Using compressed air, the
ALLU PF Pressure Feeder injects the binding agent beneath the ground through a
feeding pipe, directly to the middle of the mixing drums on the ALLU PMX Power
Mixer. The unit is mounted on a tracked chassis and is remotely controlled
allowing the unit to follow behind the lead excavator onto the site. The ALLU
PFM Pressure Feeder Mobile, which is used for feeding dry binders, is mounted
on a trailer that enables easy transportation from one place to another. This
means lower mobilization costs and enables cost-effective stabilization
projects on smaller job sites.

Acquisition Control System measures, controls and reports the feeding operation
and enables control of the whole Stabilization System, making it user-friendly,
and allows the facility to transfer data onto other computers.


  • wet site conditions can be
  • disposal of unsuitable soil
    is not required
  • imports of new material is
    greatly reduced
  • ireated material can be
    placed under structures
  • site traffic and impact on
    the environment is reduced
  • low operating costs
  • homogenous mixture
  • a wide variety of strengths
    are possible
  • by-products from industry
    can be used as raw materials
