What is a borehole clearance and why are they needed?

A borehole clearance is a survey or clearance performed before undertaking any intrusive digging or borehole drilling. This is to ensure that no obstacles or services are present in the dig area.


Borehole clearance surveys are performed by expert surveyors to ensure safety when drilling or digging borehole areas. This is because like many other surveys they are accompanied by risks.


The borehole area will be clearly marked out by the site surveyor. If a planned a borehole location appears to be in the area of a buried utility, an alternative location will be suggested and cleared by the surveyor.


Utility records should always be available prior to any clearance works taking place. Conducting a borehole clearance survey dramatically reduces the risk of a cable strike during the digging process.


DIFFERENT SURVEYS PERFORMED TO CLEAR ALL TYPES OF BOREHOLES

- Commercial borehole clearance

- Water well borehole clearance

- Domestic borehole clearances

- Piling clearances

- Agricultural clearances

- Ground structure clearance

- Environmental window sampling


WHY IS A BOREHOLE CLEARANCE NEEDED?


- To detect the presence of absence of services in preparation for the drilling of boreholes

- To locate below ground services or utilities within the clearance specified locations

- To provide a detailed investigation using non-invasive methods to locate below ground services or utilities which are within the clearance specified locations
