The complete soil improvement system
The ALLU PF Pressure Feeder is a specialized machine designed to work in conjunction with the ALLU Processor mixer in soil improvement applications. It is used to feed controlled amounts of dry binders, such as lime, cement, and other dry binders, during the mixing process. The pressure feeding system ensures complete control over the binder feed and uniform distribution, enhancing the soil’s bearing capacity, stability, and properties.
The ALLU PF 7+7 double-tank system enables continuous feeding of the binder, ensuring an uninterrupted mixing process without unnecessary stops. The pressure feeder allows precise dosing of the binder, providing the opportunity to control and adjust the amount of fed binder for optimal results.
The ALLU PF Pressure Feeder and ALLU Processor Mixer are designed to work together as a soil improvement system. This system ensures efficient mixing of the binder with the soil or material to be improved. This guarantees a homogeneous and high-quality end result, reducing costs and saving time.

Products
We have the perfect solutions for Soil improvement
Processor
The ALLU Processor is a power mixer attachment for a conventional excavator. 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.
Pressure Feeder
High capacity, tracked, intelligent feeding units for dry binders. The computer-controlled binder feed prevents any unnecessary amount of binder to be feed.
Complete system
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.
Case Studies
Allu solving problems for Soil Improvement
How does dry soil mixing work?
Dry soil mixing improves soft ground by introducing powdered binders directly into the soil and mixing them homogeneously with the existing material. The method uses the existing water in the ground which reduces the amount of reagent needed and shortens the solidification time.
What materials can be stabilized using ALLU?
The ALLU Soil Improvement System can treat a wide range of soft, wet and difficult materials, including clay, silt, peat, sludge, dredged sediments and contaminated soils. It is also suitable for applications involving mine tailings, ash ponds and liquid waste lagoons. Depending on the material and binder selection, ALLU solutions can improve bearing capacity, solidify wet materials and support contaminated-material remediation. The appropriate treatment method is determined by site conditions and project requirements.
What is mass stabilization?
Mass stabilization is a ground improvement method that strengthens weak or waterlogged soil by mixing binders, such as cement or lime, throughout the soil mass. It improves bearing capacity, stability and other engineering properties, making the ground more suitable for construction. The ALLU Soil Improvement System enables in-situ mass stabilization, treating soil directly where it is without the need for extensive excavation or material replacement.
How is dry binder dosage controlled?
The ALLU PF 7+7 Pressure Feeder uses a computer-controlled pneumatic feeding system to deliver precise amounts of dry binder into the soil. The ALLU DAC.2.1 control system manages binder delivery according to the specified project parameters while recording process data for monitoring and quality reporting. With adjustable feeding rates, operators can control binder consumption, minimize unnecessary overdosing and maintain consistent treatment quality.
What is the difference between soil stabilization and solidification?
Soil stabilization primarily aims to improve ground properties, such as strength, bearing capacity and stability, making weak soil suitable for construction. Solidification focuses on transforming soft, wet or liquid-like material into a more solid and manageable form. In environmental remediation, stabilization can also refer to reducing contaminant mobility. The ALLU Soil Improvement System supports both processes through controlled binder feeding and homogeneous mixing, depending on the required treatment outcome.
