Utility and Underground Surveys
ASES Ltd offers a full range of utility detection services using electromagnetic detection and ground-penetrating radar (GPR) methods, as well as also being able to offer specialist radar surveys.
With over 10 years’ experience in the industry, our surveyors are highly experienced in the provision of these services and are committed to delivering a product of the highest quality.
Situated in Greater London, we are able to offer nationwide coverage of our services.
Utility Mapping Surveys are carried out prior to ground investigation, boreholes, trial pits and other construction works, confirms the presence or absence of underground utilities before breaking ground or sub surface investigation.
Using a combination of non-invasive methods, including: ground penetrating radar, (GPR), electromagnetic and visual techniques, detect and map underground utilities before you dig, minimising risk of injury and costly damage to fibre optics.
The use of Radar helps us provide the most comprehensive survey, incorporating everything underground. With the increased presence of plastic and fibre optic underground services, and with many gas and water authorities replacing existing metal pipework with newer plastic infrastructure, there is an ever-growing need for radar.
We accurately identify and plot electricity, telecoms, cable TV, ductile iron water pipes and drainage pipes & gas services. Once the surface has been scanned and the services detected, we accurately survey these using traditional surveying methods or GPS.
Because the surface is immediately marked/sprayed with colours corresponding to the service, contractors have real time information on the buried services before finished plans are submitted.
If a Topographic plan in DWG already exists, we use these as the base of our survey, if not we can provide a package that includes the utility scan and Topographic Plan.

Desktop Utility Record Pack, Statutory Records.
If no existing utility records are available, it is suggested that these are obtained prior to the mapping survey. We can undertake a search of local utility company records in order to obtain details of the following underground services:
- Electric Cables
- Gas Pipelines
- Fibre Optics
- Water Mains
The data is presented in PDF (CD Rom) or hard copy format.
