Brownfield sites can often make great development sites, but sometimes they need some pre-work to ensure maximum viability. There is a wide range of different issues possible, including the requirement of earthworks or the removal/treatment of contamination.
Remediation methods on brownfield sites depend on both the type and level of contamination, how long it’s been there and the general condition of the site. We offer various survey options which will give you a better understanding of any issues on the site and will allow us to provide all the remediation methods that are available to you.
Our Brownfield Remediation methods include:
- Physical containment
- In-situ and ex-situ bioremediation
- Thermal desorption
- Soil stabilisation
- Chemical oxidation
- Vacuum extraction
It all starts with a thorough site walkover combined with a historical search to look for former uses along with geological and hydrogeological interpretation. An intrusive site survey and soil testing will then follow, which will include at least one of the following:
- Trial pits – digging a pit with an excavator
- Hand pits – a trial pit dug by hand
- Boreholes – drilling a hole into the ground
If the site contains contamination, remediation will be required. We will provide you with all the options that are available for your site, depending on your needs and budget. When the remedial works are complete, we will carry out testing through an independent laboratory to confirm that the treated material is clean and ready to be developed on.
If the site does not contain contamination, it may still require earthworks. This involves manipulating the soil levels to achieve the desired base to build or develop on. Earthworks is another service that we provide. If we discover any hazardous or non-hazardous materials during excavations, we can treat them to prevent landfill disposal, saving you money.
