Asbestos in Soils & Demolition Materials

An increasingly common legacy of former industrial sites is the presence of asbestos containing materials (ACM’s) deposited or dispersed within made ground, leading to asbestos contaminated soils (ACS) present in the ground.

This issue is typically exacerbated by poorly controlled demolition practices, resulting in ACM fragments becoming spread across the site surface and/or throughout crushed materials. The presence of ACM’s and ACS can result in significant potential liabilities, programme delays and escalating costs for developers and landowners.

Soilfix have significant experience in adopting pragmatic, robust yet cost-effective solutions for asbestos contaminated sites, fully in compliance with control of Asbestos Regulations (CAR) 2012 and relevant waste management legislation. Through accurate planning of pre-treatment and materials management requirements, the volumes of hazardous and non-hazardous wastes removed off-site can be minimised.

Works are either carried out by Soilfix appropriately trained staff under a Notifiable Non-Licensable Works (NNLW) Notification, or, where higher risk ACM’s are encountered, carried out using a licensed Asbestos Contractor. The following sustainable and cost-effective remedial measures are routinely carried out by Soilfix:

  • Selective excavation, sorting and in-situ manual picking of ACM fragments;
  • Manual picking and screening of ACM fragments, in an enclosed picking station for higher quantities of material;
  • Stabilisation and / or encapsulation of ACS to minimise the potential for residual fibre release;
  • Stringent environmental monitoring and controls, including fine-mist (virtual enclosure) suppression systems, reassurance air testing and scanning electron microscopy analysis to confirm airborne fibre concentrations are below HSE control limits as well as environmental background levels.

To guarantee compliance with CAR2012, all Soilfix employees who operate with asbestos are trained in Non-licensed/Notifiable non-licenced work are fully qualified, have routine medical exams, and have their respirator face-fitted.

bioremediation Soilfix

Bioremediation

Our specialist bioremediation service in Cardiff and the surrounding areas is carried out by our expert team. Various organic pollutants provide an energy source for naturally occurring micro-organisms present within the soil (e.g. bacteria). Under the right conditions, these organisms will degrade organic contaminants to form less toxic and/or more stable materials.

These processes can be enhanced by manipulating the conditions within the soils that enable the relevant micro-organisms to both interact and thrive with the contaminants. The presence of nutrients and available carbon within the soil will provide the foundations for the organisms and can be artificially increased with the application of various fertilisers or bio-nutrient products. Optimising pH, temperature, moisture and oxygen conditions can boost populations and enable maximum interaction with the contaminant.

Biorememediation can be accelerated within ex-situ soils using vented biopiles or windrow technology. Bio-venting, sparging or permeable reactive barriers (PRBs) can be used to accelerate the process in-situ.

Soilfix can design and build the systems that will enable you to achieve maximum rates of bioremediation at your site. Where more complex contaminant situations, gross start concentrations or biomass limited situations occur, Soilfix has experience in bio-augmentation using both specially cultured and indigenous biomass to increase the treatment process.

Stabilisation - Solidification Soilfix
Stabilisation Soilfix

Soil Stabilisation / Solidification Cardiff

A increasingly affordable technology for the quick treatment and/or immobilisation of hazardous wastes and polluted soils or sludge is soil stabilisation or solidification. The terms “solidification” and “stabilization” describe two distinct mechanisms.

  • Solidification can encapsulate dangerous components, boost compressive strength, and reduce permeability by altering the physical characteristics of contaminated material.
  • Stabilisation adjusts the chemistry of specific hazardous constituents, making them less soluble, less mobile, and/or less toxic.

Prior to beginning the work,  samples of the corrupt material are taken and laboratory pilot trials conducted to calculate the most cost effective reagent or combination of reagents to achieve the site remedial targets. Binding agents are then applied and the soils rotivated either in-situ (e.g. auger, injection, rotivator) or ex-situ (e.g. batching plant, blending equipment). Performance testing of the treated materials is usually completed throughout the works. According to the specifications, testing on hydraulic conductivity, unconfined compressive strength, and leachate characteristics may be included.

In-Situ / Ex-Situ Groundwater Treatment Cardiff

Soilfix has extensive experience in adopting a wide variety of both conventional and more innovative in-situ / ex-situ groundwater treatment technologies in Cardiff to meet site specific remedial goals and / or enable excavation and extraction of in-ground obstructions.

  • Using air stripping, filtration, and solids/NAPL separation for total fluid recovery and ex-situ treatment;
  • Surfactant-enhanced total fluids recovery through groundwater recirculation or injection;
  • Free-product recovery (with and without vacuum-enhancement) using pneumatic skimming, dual-phase and multi-phase vacuum extraction systems;
  • Air sparge / SVE systems (including use of ozone);
  • Enhanced natural attenuation techniques for both aerobic and reductive treatment to stimulate accelerated biodegradation (for solvents, trace organic compounds and hydrocarbons) or precipitation (e.g. hexavalent chromium); and,
  • Reduction technologies / in-situ chemical oxidation.

With the help of qualified partners, Soilfix has also performed thermally enhanced treatment utilising both steam and electric conductive heating.
