We have categorized our techniques into four main segments.
Our Consolidation and Elements segments provide solutions for the construction of embankments or fills on compressible soils like clay or peat. Our solutions in the consolidation segments relate to a full loading of the soil while in the elements segment the load is (partly) transferred by the elements to bearing strata.
The techniques in our Compaction segment provide a solution for the densification of granular material
The Barrier segment hold all our techniques that create a barrier for either soil or water.
If consulted at an early stage we can help you ensuring the project is delivered using the most appropriate techniques to the prevailing conditions and budget expectation. Feel free to get in contact with one of our specialists.
Please find below links to pages showing more detail on each segment and each solution within this specific segment.
