Land Remediation


Remediation And Stabilisation

Land remediation and stabilisation comprise of a series of processes that aim to return the land to a clean and safe condition.  This type of work may be used to return brownfield sites to a more natural state, or it may also be used to convert previously unusable or contaminated land into a space suitable for development.  Here at R Collard, we have over 25 years’ experience in providing high-quality remediation and stabilisation services at a variety of different projects across different sectors.  Site remediation is the process of removing polluted or contaminated soil, sediment, surface water and groundwater to reduce the impact on people or the environment.  To find out more about our remediation and stabilization services, please get in touch with us today on 01252 844688.

We offer a comprehensive range of skills, services and resources to carry out ex-situ and in-situ remediation to decontaminate Brownfield sites and prepare them for the re-development phase.

The land and groundwater on former industrial locations is often polluted with hydrocarbons, heavy metals, fertilizers and asbestos which pose a risk to the health of contractors, residents and the wider public of any future development.

We provide developers with a complete remediation package from consultancy to sampling and testing, excavation, treatment, re-deposit, re-grading and waste disposal. Our vast experience of the discipline enables us to provide expert advice and value-engineering to ensure the most suitable and cost-effective remediation methodology is used.

We can carry out all of the excavation and associated enabling work including liaising with the Environment Agency which strictly regulates this discipline. Our WAMITAB-accredited management team will monitor and document the source, processing techniques and destination of all remediated material to provide full chain-of-custody and traceability required by the Regulations.

The Remediation Process

Initially, our surveyors will visit your site to undertake thorough ground investigation services to best identify signs of significant contamination.  We do this by using industry-leading equipment to achieve efficient and productive results so that we can accordingly.  Generally, groundwater and gas testing is carried out via monitoring wells installed during the site investigation works and we will also test and collect samples of underground water and soil to check for thorough contamination analysis.  Whatever the cause of the land degradation, getting the site back to a usable condition requires specialist knowledge and expert capabilities.  As well as contamination analysis and classification, our remediation and stabilisation services also include;-

  • Haulage.
  • Soil remediation treatments.
  • Asbestos surveys.
  • Asbestos removals.
  • Developing strategies.
  • Sampling and surveying.
  • Safe disposal.

Our expertise includes the following remediation technologies:

  • Pick/Sort – typically used to process land contaminated with asbestos
  • Bio-remediation – controlled treatment of contaminated land with biological agents to degrade and neutralise hydrocarbons, nitrate and sulphate-based fertilizers
  • Soil stabilisation –excavated material treated with chemical additives such as lime, ash or cement to immobilise and encapsulate contaminants and increase the strength and load bearing capacity
  • Screen/Sort –removes non-hazardous material such as hardcore, timber and stone to produce a homogenous sub-base
  • Soil washing – uses detergents to clean and decontaminate material with high granular content
  • Pump & Treat – involves pumping contaminated groundwater to a purification facility where it is treated with chemical reagents and filters

Why is remediation important?

Remediation is important for a number of reasons.  Remediation is ultimately the process of removing pollution from the environment and from your site which can be found and identified in a number of natural materials such as soil.  If it has been discovered that your soil is polluted, it could have a severe negative impact on your health, your family, your neighbors, and the environment.  Therefore, before any development work and construction work proceeds, it’s absolutely imperative to hire a company just like R Collard and invest in remediation and stabilisation services.  Land remediation plays a critical role in many construction jobs.  It's the process of cleaning up contaminated lands, usually, prior to building works to ensure that groundwater doesn't become polluted and the area is safe to build on.

Are remediation and stabilisation services always best undertaken before construction work?

Yes, of course.  Remediation and stabilisation services are always best being undertaken before any project work begins.  This is because our surveyors can effectively identify signs of contamination and pollution on site and remove them before the project begins.  This is much better than the alternative of finding contamination during the building process which can cost companies a lot of money and wasted time.

How is contaminated land treated?

Contaminated land can be treated in a number of ways.  Biological treatment and bioremediation uses bacteria to break down substances in the soil but chemical oxidation is also a common method that helps to convert contaminated soil into non-hazardous soils.

What is classed as contaminated soil?

Land is legally defined as 'contaminated land' where substances are causing or could cause: significant harm to people, property or protected species and significant pollution of surface waters (for example lakes and rivers) or groundwater.

Is this a standalone service?

Remediation and stabilisation is an imperative service that we highly recommend before the start of any construction or development project.  This service that we provide is available as an individual service or part of a bigger project.  We are happy to discuss your requirements and offer our services based on your specifications and budget.
