URETEK SOILBONDING®
URETEK is recognised worldwide as a technically advanced specialist in the restoration of subsided concrete floors and steel foundations.
URETEK SoilBonding® is an advanced foundation technique specially developed to ensure the stability of building structures by bonding layers of sand beneath the foundations. This method makes it possible to carry out excavation work on adjacent plots without causing subsidence.
Principle of operation
In the URETEK SoilBonding® method, resins are injected into the sand layers beneath the foundation. These resins form a solid ‘wall’ that significantly increases the bearing capacity of the soil. The resin bonds the sand grains together, creating a solid and stable subsoil.
Areas of application
The URETEK SoilBonding® technique is widely applicable in both new-build and refurbishment projects.
Some examples of areas of application include:
- Extensions to existing buildings;
- New-build projects in densely built-up urban areas;
- Projects requiring excavation work on adjacent plots.
Conclusion
URETEK SoilBonding® offers an innovative and effective solution for stabilising foundations in a variety of construction projects. The use of expanding resins creates a durable and reliable subgrade, thereby preventing settlement and ensuring the stability of the structure.
Preparation
Prior to the injections, a thorough soil investigation is carried out to determine the suitability of the soil for the URETEK SoilBonding® method.
Injection
The resins are injected into the sand layers beneath the foundations via injection lances. The resins bind the sand grains together, creating a firm and stable subsoil.
Completion
Once the injections are complete, the injection lances are removed and the work is finalised. The foundation is now stabilised and can immediately bear its full load.
Benefits of URETEK Soilbonding®
- Minimal disruption: The work can often be carried out from outside, minimising disruption to residents and businesses.
- Rapid implementation: The injections can be carried out in a short space of time, significantly reducing construction time.
- Long-lasting results: The bonded sand layers provide a durable and reliable solution to foundation problems.
- Cost-effective: Costs are kept low thanks to the rapid and efficient execution of the work.
