Bonding of sand layers beneath foundations to ensure the stability of structures.
URETEK SOILBONDING®
URETEK is recognised worldwide as a leading technical specialist in the field of rehabilitating subsided concrete floors and steel foundations.

URETEK SoilBonding® is an advanced foundation technique specifically developed to ensure the stability of buildings by bonding sand layers beneath the foundations. This method allows excavation work to be carried out on adjacent plots without causing ground subsidence.
How it works
The URETEK SoilBonding® method involves injecting expanding resins into the sand layers beneath the foundations. These resins form a solid ‘wall’ that significantly increases the bearing capacity of the ground. The expanding resin expands and binds the grains of sand together, creating a solid and stable base.
Areas of application
The URETEK SoilBonding® technique can be used extensively in new-build and renovation projects. Here are some examples of areas of application:
- Extensions to existing buildings;
- New-build projects in densely populated urban areas;
- Projects requiring excavation on adjacent plots.
Conclusion
URETEK SoilBonding® offers an innovative and effective solution for stabilising foundations in various construction projects. The use of expanding resins creates a durable and reliable ground that prevents settlement and ensures the stability of the structure.

Preparation
Before the injections, a thorough soil investigation is carried out to determine the suitability of the soil for the URETEK SoilBonding® process.
Injection
The expanding resins are injected into the sand layers beneath the foundations using injection lances. The resins expand and bind the sand grains together, creating a firm and stable surface.
Completion
Once the injections have been carried out, the injection lances are removed and the work is complete. The foundation is now stabilised and can immediately bear its full load.
Advantages of URETEK Soilbonding®
- Minimal disruption: The work can often be carried out from the outside, thereby minimising disruption to residents and businesses.
- Rapid execution: The injections can be carried out quickly, significantly reducing the duration of the works.
- Long-lasting results: The bonded sand layers provide a permanent and reliable solution to foundation problems.
- Cost-effective: Thanks to the rapid and efficient execution of the work, costs remain low.
