Prior to any sub surface site investigation taking place it is appropriate to search for buried services.
Failure to establish accurate positions of any buried utility or other potential hazard is not only detrimental to the costing of a project but has a far more serious implications when considering health and safety issues.
A buried services search reduces the risk our clients may be exposed to when investigating brown and green field sites.
A chat with one of our experts will only take a few minutes but could prove an enormous cost saving in the long run.
What sort of equipment is used for underground search surveys?
We use EM + GPR technology:
EM (Electro Magnetic) technology traces live services or known services that a low voltage electric pulse can be passed along and traced from the surface.
GPR (Ground Penetration Radar) once all known services have been traced using EM, GPR is then used to scan the site for any services which are unable to be located by EM e.g. plastic pipes or unknown services.
Do buried services searches detect everything?
No underground utilities will trace most services on site using a combination of service records, EM + GPR. The majority of services will be traced. There are limitations however. Services which are too deep or too small for GPR to get a clear reading and are not shown on statutory record plans may not be detected.
Can you tell how deep the services are?Yes the GPR + EM equipment lets us know the depth of the service being traced.
