Ground Penetrating Radar (GPR) Surveys
Ground Penetrating Radar (GPR) Surveys can provide vital insight during pre-planning to ensure a safer excavation and avoid service strikes. Using the ground penetrating radar to survey underground, the GPR survey team will scan your site to provide detailed information on cables and ductwork that may affect excavation works.
Our knowledge of land surveying and setting out, both from an engineering background, allows us to provide project management support prior to design and construction.
What can Ground Penetrating Radar (GPR) Surveys locate?
Underground tanks, manholes, pits, voids, steel reinforcement in concrete, plastic pipework and more!
If you need to locate underground services before commencing ground excavation, then a GPR survey can help. Our Survey technician will work with you to locate all underground utilities, tanks, pits and voids, to ensure you have a full picture of what is buried underneath your site. Often maps of local services can be outdated, or may need to be sourced from various utilities providers, making it difficult to ensure you have located all services.
We can also supply the GPR survey equipment and or the RD 8000 cable locating toll on a non-operated hire with durations to suit your requirements. GPR survey training can also be provided.
Why undertake a Ground Penetrating Radar (GPR) Survey?
The Health and Safety Executive’s guidance for avoiding danger from underground services recommends 3 steps for safe excavation. Firstly companies should carefully plan works, will extensive consideration given to how excavation works can be undertaken as safely as possible. Secondly all underground services should be identified, detected and clearly marked so all site workers can see where potential danger lies underneath the ground. Finally areas where underground utilities are located should be safely excavated using safe digging practices.
