ALLU Soil Improvement is versatile, efficient, and cost-efficient material mixing and soil stabilization technology. It is equipment you will wish you would have found sooner.

Mainly used across Civil engineering projects, Costal facilities, solidification, and contaminated site remediation we have your aspect covered.


The ALLU Processor is a power mixer attachment for conventional excavators.

This attachment converts the excavator into a powerful and versatile mixing tool capable of penetrating and effectively mixing a variety of difficult materials – everything from clay, silt, peat, sludge and sediment, to dredged material and contaminated soil.

ALLU pressure feeders 7+7


The ALLU PF Pressure Feeder is a self-contained, two-tank, pneumatic-based dry binder delivery system.

It uses an on-board air compressor to pressurize a tank of binder and deliver it in dry form. Delivering and mixing binder in dry form conserves the “drying” capacity of a binder. It’s a highly cost-effective solution when wet soil or sediment needs to be stabilized.

The computer-controlled feed enables the binder to be added precisely, which reduces costs and increases quality on the jobsite.


ALLU’s Soil Stabilisation System consists of a pressure feeder, a power mixing unit and a control system.

The whole process is monitored via ALLU DAC that measures, controls and reports actions made. With this machinery, you’ll be able to harden soft soil by adding binder to the ground. In addition to this the equipment works perfectly for processing and encapsulating contaminated materials.

ALLU pressure feeder 7+7 mobile feeder



The ALLU PF 7+7 is a self contained mobile feeder for deep dry mixing, the track driven feeder is completely road legal and easy to transport on a low bed trailer making it extremely mobile. Fast setup on jobsite results in less down-time and the large air capacity gives improved productivity.
