Soil improvement & building stabilization

Soil improvement & stabilization of structures by injection of expanding resin

By means of expanding resin injection into the ground under the foundations of a structure, the URETEK® process provides a treatment that improves the resistance of the ground and thereby stabilizes the structure in a sustainable manner.

 curative use

In the event of deformation of the ground, this very often causes damage such as subsidence of foundations or paving and generating cracks on the building.

In all situations requiring the improvement of the bearing capacity of the soil, the underpinning by injection of expanding resin is used as a curative. The application of the solution can if necessary be used to raise the collapsed structure.

 In preventive action

The process can also be used preventively to consolidate the ground under the foundations of a structure before its rehabilitation. This may concern modifications to load descents, the bringing into conformity of an ERP requiring an elevator, the replacement of one or more floors of wooden floors by concrete floors as part of an elevation.

 Many use cases

This solution can be applied to all types of foundations: strip footings, isolated footings, blocks, masonry, etc.

It can be used on all types of works: industrial buildings, buildings, structures or historical monuments...

 A unique URETEK® resin

The solution has a resin specially designed for deep injections, the latter was developed in the laboratory and tested on numerous construction sites. It has unique characteristics with a strong power of expansion, a stable and controlled reaction, a very good resistance to compression and a density that does not weigh down the floors.

Real-time radar surveillance

On sensitive structures such as large buildings or old buildings, radar surveillance can be set up and offers 3D structural control guaranteeing the safety of soil improvement injections and better monitoring of the treated structure.

During the injection phase, several hundred predefined points on the structure are continuously monitored, allowing the slightest movements to be detected and monitored regardless of their direction.

Thanks to readings taken in real time, this monitoring makes it possible to react at any time during the intervention and adjust the injections to meet the final needs. This guarantees control in accordance with standard NF EN 12715.

The advantages of this solution

• Maintenance of site activity

• Immediate efficiency

• Economical alternative to traditional underpinning techniques including micropiles

• Direct intervention under the foundations without damaging the structure

• Possibility of partial and localized intervention

• Rapid intervention and immediate result

• Minimally invasive technique

• Clean and nuisance-free site
