Ground Improvement

GDL have invested in the latest technology and specialist plant to allow us to offer a range of ground improvement techniques.  This gives us the opportunity to apply our technical expertise and to increase the range of challenging soil conditions that we can overcome.

Our ground improvement systems offer the following benefits

• Simplified foundation design for subsequent structures and features;
• Little or no excess spoil is generated during the construction process;
• By re-engineering site-won soils we can reduce or remove the need for imported aggregate and concrete, and this increases the sustainability of construction projects.

Soil stabilisation can be used in conjunction with our earthworks services to modify site-won soils to allow these to be recompacted in accordance with specified requirements. Soil stabilised piling mattresses offer an alternative to imported aggregate and reduce the disposal of surplus excavated spoil off-site.

Deep soil mixing is typically used to improve the strength and stiffness characteristics of soft to very soft formation soils including peat, and this technique can also be designed as a composite ground improvement system to control settlement.

Low permeability cut-off walls can be constructed using a number of techniques including soil mixing, slurry walls and jet grouting.

Vibro Stone Columns are one of the most commonly specified ground improvement methods in the UK since, given the correct soil conditions, they can provide a relatively inexpensive and quick method of ground improvement.
