The works comprised the following:

  • Site investigation, including sampling, and laboratory test- ing for determination of optimum binder use, including probing of existing sub-grade to determine subterranean soils stiffness modulus and earthworks strategy develop- ment
  • Removal of existing top-soils, certified acceptable for re- use and transferred to appropriate transfer facility for recy- cling / re-use to satisfy Article 6 of the waste framework directive 2008 (as amended by directive (EU) 2018/851).
  • Removal of existing hardstands and paved areas and segre- gation on-site for re-processing.
  • Excavation of existing made grounds to competent strata beneath proposed building and treatment to improve soils bearing capacity of fills for shallow pad foundations and ground bearing floor slab solution.
  • Large scale earthworks exercise with all unsuitable material treated to improve engineering properties as acceptable earthworks material to meet the site specific engineering performance specifcation.
  • Surface stabilisation of formation to achieve Hydraulically Stabilised Soils in accordance with MCHW Vol.1 series 800 cl.840 (Subbase Replacement)
  • Extensive geotechnical testing of material re-use to verify the performance specification in line with the client con- sultant requirements.
  • Management and control of surface water, perched ground- water.
  • Installation of a granular surface formation abrasion layer.

TR Stabilisation, adopted an holistic approach, to ensure fixed costs where within budget, and delivery of the project within the allocated timeframe accommodating partial handover for release to follow on construction phase activities.
Environmental & Sustainability savings:

Reduced depletion of natural resources (aggregates) associated with Granular 6F, DoT Type 1 subbase.

Reduction in disposals off site to landfill.
