POLYJET is an advanced polymer injection technology used to stabilize and strengthen soils and foundations on problematic sites where conventional geotechnical methods are ineffective or economically unfeasible.
It is designed for high-responsibility projects requiring precision, speed, and minimal disruption to ongoing operations.

Applications
POLYJET is used in a wide range of geotechnical and structural scenarios, including:
Differential settlement of buildings and structures
Cracking of structural elements
Loss of soil bearing capacity
Water filtration and soil erosion
Deformations under dynamic and vibrational loads
All work can be performed without dismantling structures and without interrupting facility operations.
How POLYJET Works
Polymer formulations are injected into the soil through small технологические отверстия or low-diameter injection tubes.
During the reaction, the material expands and forms rigid polymer structures that:
During the reaction, the material expands and forms rigid polymer structures that:
- Densify the soil
- Create three-dimensional reinforcement
- Displace water from soil pores
Mechanism of Soil Improvement
POLYJET injections modify the soil’s physical and mechanical properties in a controlled manner. The process:
Increases soil density and bearing capacity
Redistributes loads within the soil mass
Forms a stable reinforced structure
Reduces permeability
As a result, it halts deformation, stabilizes foundations, and extends the service life of structures.
Performance in Saturated Soils
POLYJET is effective in high groundwater conditions.
During expansion:
During expansion:
- Pore space is reduced
- Water is displaced
- Soil becomes denser and more stable
- Has lower filtration capacity
- Is resistant to erosion
- Retains bearing capacity even after re-saturation
Advantages Over Conventional Methods
Compared to piles, soil replacement, cement grouting, or concrete structures, POLYJET:
- Does not require shutdown of operations
- Eliminates the need for heavy machinery
- Allows precise application without structural damage
- Works in confined or hard-to-access areas
- Reduces project timelines
- Minimizes risks on critical sites
Application Under Existing Foundations
POLYJET enables precise, localized reinforcement beneath existing structures, including loaded or deformed foundations.
The short reaction time prevents uncontrolled material migration, ensuring predictable results.

Engineering Workflow
POLYJET projects follow a full engineering cycle:
Analysis of initial data and task definition
Site inspection and identification of root causes
Engineering calculations and solution design
Selection of technology and injection parameters
Engagement of certified contractors
Supply of materials and equipment
Supervision and quality control
Final verification of results
The focus is on delivering measurable engineering outcomes, not just materials.
Quality Control
Quality is ensured through multiple control stages:
- Incoming material inspection
- Monitoring of injection parameters
- Structural and instrumental verification
- Preparation of as-built documentation
Typical Project Types
POLYJET is applied in B2B and B2G projects, including:
Optimal Conditions for Use
POLYJET is particularly effective:
- In high groundwater conditions
- On weak, heaving, or anthropogenic soils
- In multilayered soil profiles
- In remote or restricted-access locations
- When rapid results are required without stopping operations
Preparatory Requirements
POLYJET typically requires minimal preparation and does not involve:
- Structural dismantling
- Large-scale earthworks
- Heavy equipment deployment
