Soil Stabilisation and Containment Systems

Stabilisation / solidification generally involves the use of chemical additives to chemically bind and immobilize contaminants or to encapsulate them in a matrix.

Stabilisation / solidification generally involves the use of chemical additives (e.g. cement, lime and GGSB) to chemically bind and immobilize contaminants or to encapsulate them in a matrix that physically prevents mobility. Solidification is a physical process where a semi solid material or sludge is treated to render it more solid. Stabilisation refers to the chemical process that actually binds the matrix of the contaminant such that its constituents are immobilized.

These techniques can be used alone or in combination with other treatment and disposal methods and with sound engineering design; these systems can provide an effective long-term remediation and engineering solution.

Soil stabilisation techniques have many benefits in today’s construction and remediation market. CRL have the experience and proven skills to provide design and application solutions including:

  • Geotechnical Improvement - reduce the moisture content of cohesive soil thereby improving its bearing capacity
  • Contaminant Encapsulation - reduce the soil's permeability and prevent the leaching of contaminants.
  • Product Production - processing unsuitable material into engineering fills e.g. Highway Specification 600 series

CRL has an in-house capability in stabilisation/solidification technology, with our own laboratory harnessed to undertake pilot trials and bench testing, we can provide bespoke design parameters tailor-made for a specific project.
