Trial Holes

For new-build house developers a trial hole investigation can provide specific information detailing existing underground utility apparatus including LP and HP gas, HV and LV electric, water and telecommunications. This can be particularly useful at a proposed new site entrance as well as on-site before building work commences to safely locate utility connection points or to avoid costly utility diversions.

Our trial hole service includes exploration and surveying of existing utility apparatus both on and off site. A full report detailing our findings with both written and photographic evidence can be provided. Where trial holes are required on the public highway, we can liaise with the local authority to obtain the necessary permits, arrange traffic management and ensure full reinstatement to meet the local authority’s requirements. All of our operatives are qualified to NRSWA standard and we are fully insured.

Health and safety guidance is ever-changing and the requirement for non-mechanical excavation, especially in the vicinity of live utility cables is becoming more and more common. J Wilson Contractors Ltd recognises this need and has recently invested in new equipment to carry out safe excavations. Our compact vac-ex allows us to safely excavate around live services with minimal risk of damage to the existing apparatus or to the operative.
