asbestos

Asbestos in Soils & Demolition Materials

The presence of asbestos is becoming more prevalent in former industrial sites, which contains materials (ACM’s) deposited or dispersed within made ground, resulting in asbestos contaminated soils (ACS) present in the ground.

This concern 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 accelerating costs for developers and landowners.

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

All asbestos removal works are either carried out by Soilfix employees with the necessary training 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;
  • Screening and manual picking of ACM fragments, in an enclosed picking station for higher quantities of material;
  • Stabilisation and / or encapsulation of ACS to minimise the likelihood 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.

All Soilfix staff working with asbestos are Non-licensed/Notifiable non-licensed work trained and have regular medicals and respirator face-fitting to ensure compliance with CAR2012.

bioremediation Soilfix

Bioremediation

Our specialist bioremediation service in London and the surrounding areas is carried out by our expert team. Various organic contaminants provide an energy source for naturally occurring micro-organisms existing in 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 excelled by manipulating the conditions within the soils that enable the relevant micro-organisms to both interact and thrive with the contaminants. The soil’s availability of carbon and nutrient content 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 temperature, moisture, pH and oxygen conditions can expand 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 London

Stabilisation / Solidification of soils is increasingly a cost effective technology for the rapid treatment and / or immobilization of hazardous wastes and contaminated soils or sludge’s. The terms “solidification” and “stabilization” describe two specific mechanisms.

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

Prior to commencing,  samples of the corrupt material are taken and laboratory pilot trials conducted to determine 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. This may involve testing for hydraulic conductivity, unconfined compressive strength, and leachate properties, depending on the requirements.

In-Situ / Ex-Situ Groundwater Treatment London

Soilfix has extensive experience in adopting a wide variety of both conventional and more innovative in-situ / ex-situ groundwater treatment technologies in London 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,
  • In-situ chemical oxidation / reduction technologies.

Additionally, Soilfix has expertise performing thermally enhanced treatment with both steam and electric conductive heating with the help of qualified partners.
