Georesin Column Injection - an overview of geopolymer column injection technology

Column Injection is a geopolymer column injection technology developed by Georesin for strengthening weak soils and stabilizing subsiding structures. This method is used where traditional soil stabilization methods are no longer effective or are ineffective.

The technology enables the formation of durable geopolymer columns in the ground, which act as load-transfer elements, friction piles, or compact structures—depending on the soil type and the intended application.

Column Injection Applications

The injection technology for geopolymer column formation is quite versatile in its application, and can therefore be widely used on various types of facilities, regardless of scale.

• Sea and river ports, dams;

Is this how such versatility is achieved?

On the one hand, Column Injection has all the advantages of Georesin geopolymer materials, such as high penetrating ability and curing speed, hydrophobicity and chemical inertness, compact equipment and cleanliness of work.

On the other hand, Column Injection gains the advantages of classic pile technologies:

• The ability to transfer loads to stable underlying soils without the need for additional injection material to strengthen the entire volume of weakened soils. This allows the technology to be used in applications where injection techniques previously required high material consumption.
• The ability to operate on the “quasi-friction pile” principle (friction pile). The soil-polymer mass does not need to reach the underlying soils. This is because the mass provides bearing capacity by compacting soft soils due to the increased pile volume and the polymer’s adhesion to them.

At the same time, they do not have the typical disadvantages of bored piles, such as bulky equipment, high material consumption, and limitations in working with the reinforcement of existing structures.

Column Injection Functions and Operation

Therefore, the technology is based on

1. Compaction of soft soils.ExpandingGeopolymer fills pores and compresses loose soil layers, eliminating the cause of subsidence.
2. Using friction forces.The hardened column acts as a friction pile – particularly effective in clays, organic soils and water-saturated layers.
3. Using cohesion.The geopolymer structure forms a monolith that interacts with the surrounding soil due to its uneven geometric shape and adhesion to the surrounding soil over its entire area.

Technological process of installing a geopolymer column

1. Drilling a hole Ø ~50 mmthrough the foundation into the ground.
2. Installation of a special flexible packerinto the well.
3. Injection of fast-hardening geopolymer.
4. The required diameter of the soil-polymer massif in the groundcan be selected to suit specific technical conditions of the project and has no strict limitations.
5. Instant formation of bearing capacitywithout hydraulic pressure – expansion is provided by the chemical reaction of the geopolymer material Georesin.

In this case, all work is carried out using the systemReal-time injection control, allowing work to be carried out with high precision, in accordance with the design.

Advantages of Georesin geopolymer columns

• 5 times faster than traditional methods.Installation takes a few days, not weeks or months.
• Minimally invasive.Compact and quiet equipment allows work to be carried out in confined spaces without disrupting business processes at the customer’s site.
• No excavation work.The possibility of strengthening the foundation soils without the use of construction equipment and digging foundations.
• Durability of geopolymer.Georesin is a chemically inert material., it does not deteriorate in water-saturated soils and is ideal for the climate zone of Ukraine.
• Environmentally friendly.The lowest environmental impact among foundation strengthening methods.

Timelystandard for strengthening soft soils

Georesin Column Injection technology enables rapid, non-destructive, and minimally invasive stabilization of foundations, reinforcement of weak soils, and restoration of structural load-bearing capacity in the most challenging conditions. It can be combined with Deep Lifting, Floor Lifting, and Benefil to achieve results even in the most challenging applications requiring soil stabilization, lifting of subsiding structures, and filling of large cavities.
