First CMC project carried out by Menard in Denmark
The first Controlled Modulus Column (CMC) project in Denmark is located nearby Solrød Strand, west of main highway to Copenhagen, the E20. Menard improved the uncontrolled fills and glacial deposits of clay, silt and sand layers over a depth of 7 to 15 metres for one Unit of the new warehouse area.
About 3,000 Controlled Modulus Columns with a diameter of 280 mm were installed below the slab, the foundation structure and the loading area of the future building, with anchoring in the dense sand layer. The 20,000 sq. metre area was treated just within 10 weeks only with one CMC rig.
Advantage of CMC rigid inclusions
The main advantage of the CMC ground improvement technique compared to a regular piling solution was a thinner ground bearing slab with lighter reinforcement. Because of the CMC grid in combination with the granular distribution mat an optimized shallow foundation system could be designed
Load tests with 40 tonnes were carried out on the isolated CMC to ensure compliance with the settlement criterion.
This project was handled by our teams in Germany in 2021.
