Development space is at a premium within the South and South East of the UK and considerable pressure is being placed to ensure that existing brownfield sites are re-used and maximised wherever possible. This trend within the market led to the formation of Erith’s Remediation Division which has recently been supplemented with the development of a specific Earthworks, Infrastructure and Civil Engineering capability within the Group.

Building on the skills in the Group, Erith continue to develop a plan to ensure that we have the necessary skills and experience within our Earthworks, Remediation and Infrastructure Division to cater for the construction industry. This foresight has ensured that the business has a considerable presence within the fi­eld, developing close working relationships with a number of major clients. Erith’s clientele within this sector includes national house builders, large property developers, blue chip contractors and UK utility providers.


Erith frequently undertake the construction of infrastructure and early works as principal contractor and follow on with traditional earthworks and civil engineering for the development providing programme advantage and a single point responsibility for the client.

Activities include:

  • Bulk Earthworks and Disposal
  • Basement Excavation
  • Secant, Contiguous and anchor pile walls
  • Sheet Piling & Mini Piling
  • Pile Caps and Ground Beams
  • RC Substructure Works
  • Foundation Construction
  • Suspended and Ground Bearing Floor Slabs
  • Storm and Foul Water Drainage Installation
  • Adoptable Highways
  • Hard and Soft Landscaping

Land Remediation

Contaminants dealt with have included: toxic materials, heavy metals, asbestos, hydrocarbons and a broad range of chemicals including both pharmaceutical and pesticides. The remediation of such hazardous materials has led to the evolution of specialist remedial techniques consisting of some of the following methods

  • Bio Remediation
  • Ground Water Treatment
  • In-situ and Ex-situ Ground Validation
  • Stabilisation
  • Enhanced Complex Sorting
  • Ex-situ Bio-augmentation

In recent years, Erith have retained status as framework contractors for both National Grid Property Holdings and Wales and West Utilities.

These frameworks have consisted of the Land Remediation of contaminated land coal carbonisation assets across the UK.
