Soil Improvements

Here you will find technical details of our Soil Improvements capability.

Earth Embankment

  • Slopes between 60° – 65°. Typically can be created with horizontal reinforcement design and installed typically of length 70% vertical height Granular stone or growing medium facing.

Soil Nails

  • We offer a variety soil nailing solutions for slope stabilisation/temporary retention works.
  • Non anchored.
  • Grouted Bar.
  • Ductile Pipe system.
  • Anchored.
  • Rock Drilled grouted bar.
  • Mechanical

Electro-Kinetic Osmosis

  • One process that could greatly enhance the transportation of chemicals through the soil is electro-osmosis.
  • Electro osmosis is a under-utilised technique that has the potential to improve the foundations of existing structures in the UK.
  • The largest potential benefit is the avoidance of far more disruptive underpinning operations.
  • Clay is 5000 times more porous under an electrical gradient than normal.
  • When an electrical potential is created a charge is forced between the electrodes.
  • The anode releases cations that migrate towards the cathode along with water
  • The cations chemically change the physico-chemical properties of the soil

Electrical Resistivity Imaging (ERI)

  • A 2D tool to recognise tree related subsurface dessication
  • Non-Invasive Tool to assess tree-induced subsidence
  • By characterising seasonal subsurface moisture content distribution.
  • Helps to define the architecture of the tree root system
