PROJECTS

Former Depot - Girvan

1000m3 of gas oil and diesel impacted soils
Intrusive investigaton to deliniate contamination
DQRA prepared
Remediation options appraisal, treatment method selection and agreement with Regulartory Authorities
Stockpiling, screening and aeration of impacted soils
Validation testing and preparation of certification report

1250m3 of 'heavy' hydrocarbon and PAH impacted soils
Intrusive investigaton to deliniate contamination
DQRA prepared
Remediation options appraisal, treatment method selection and agreement with Regulartory Authorities
Soil stabilisation using cement and stabilisation agents
Validation testing and preparation of certification report

Site partially underlain by a landfill site
Peer review undertaken
Intrusive investigation to provide geotechnical and environmental information, including cable percussion and rotary cored boreholes, trial pitting and dynamic probing together with gas and groundwater monitoring
Piled foundation solution recommended

DTS have completed several hundred petrol forecourt investigations
Typically including a PRA followed by a ground investigation on an operational forecourt, including numerous methods of borehole drilling following vacuum extraction to minimise the risk of damaging underground services
All of our engineers hold SPA cards for working on petrol forecourts
DTS also maintain a watching brieg during removal of fuel lines, tanks and interceptors
Where contamination is encountered, a DQRA is undertaken to determine the requirement for remediation

PRA and CMRA identified four mineshafts beneath a car park.
Rotary probe holes drilled in order to locate the shaft which was subsequently filled with grout
All works were undertaken under appropraite permits from the Coal Authority

Rotary boreholes drilled in a city centre building with narrow access and low-headroom - boreholes drilled from ground level through a basement into underlying strata
Window sampling boreholes drilled behind a high street store in London. Modular window sampling rig was transported up a flight of steps in order to obtain the required contamination and geotechnical information
Concrete coring and windonw sampling drilling within numerous operational food processing facilities, using electrically powered drilling equipment.
