Great development sites sometimes 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 general conditions. We offer various survey options which will tell you more and provide the options available. Soil can often be re-engineered and be made available for re-use on site.
Our Brownfield Remediation methods include:
- Physical Containment
- In-situ and ex-situ bioremediation
- Thermal desorption
- Soil stabilisation
- Chemical oxidation
- Vacuum extraction
Our process of Brownfield Remediation:
It all starts with a thorough site walkover combined with a historical search to look for former uses along with geological and hydro geological interpretation. An intrusive site survey 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 contamination is confirmed on the site, remediation will be required. We will provide all the options available depending on your needs and budget. Once completed, tests will be completed to confirm completion and the site will be handed back over.
Earthworks may also be required on brownfield sites that require no remediation, which involves manipulating the soil levels to achieve the desired base to build or develop upon. We can help with this while enabling retention of the excess soil for another use. Any hazardous or non-hazardous classified soil that has been excavated can be treated to prevent landfill disposal.
