Menard offers economical solutions for ground improvement that can be attractive alternatives to deep (pile) foundations. Our versatile range of technologies include Controlled Modulus Columns™, Dynamic Compaction™, Dynamic Replacement™, Menard Vacuum™ Consolidation, Rapid Impact Compaction, Vibrocompaction, Vibro Concrete Columns, Vibro Stone Columns and Wick Drains.
Menard evaluates the site and improvement criteria to select the most appropriate ground improvement method.
Ground Improvement without additional material:
For granular soils (sand, gravel), densification is primarily achieved by means of vibration. For cohesive soils (clay, silt), consolidation by pre-loading (constructing an embankment surcharge or applying a vacuum) can be significantly accelerated through the use of a drainage system.
Ground Improvement with additional materials:
These techniques consist of making flexible, rigid or semi-rigid vertical inclusions (columns) in compressible soil layers. These inclusions are laid out following a regular surface grid. The inclusion material is either dry and cohesionless (stone columns and dynamic replacement pillars) or grout based (controlled modulus columns and vibro concrete columns). The resulting soil layer behaves like a composite material with improved characteristics.
