With ever increasing man-made structures such as roadways, bridges, industrial facilities and more being built over and in our highly varying ground conditions, we are more often beginning to see sinkholes and cavity's forming and destabilizing infrastructure.
Whilst we are not overly prone to natural sinkholes, cavity's and voids from in adequately prepped grounds, failing subsoil and storm water systems and water flow are becoming more common. Briton Detection & Inspection takes a unique approach to the locating and inspection of voids below our infrastructure using our Aerial and Ground based Infrared Systems, our unique IR-HPA & IR-VPA system and Ground Penetrating Radar (GPR). We also use a range of steerable micro CCTV systems for visual inspection of cavity’s to allow consideration of pilot hole filling and stabilization, rather than excavation in certain situations.
Briton Detection & Inspection's combination of methods and unique approach provides reliable underground cavity detection and assessment whilst maintaining efficiency over large areas.
With an array of pipework such as storm water drainage, subsoil drainage, sewer systems and fresh water supplies situated below our pavements we are beginning to see more collapsing of our pavement structures due to pipework faults as well as natural occurrences such as sinkholes or under wash where pavement has been constructed over unsuitable grounds. Briton Infrared provides a highly specialized service for the locating of voids before collapse using out Ground and Aerial Infrared systems & IR-VPA coupled with Ground Penetrating Radar (GPR).
With many of NZ industrial & commercial sites built over low lying grounds close to sea level and over or near storm water drainage systems we are more often beginning to see slab flooring failures do to the form of either natural sinkholes or voids created by failing drainage systems. Briton locates voids below concrete using our unique IR-VPA system and Ground penetrating radar. We also offer pilot drilling and CCTV inspection of voids for volume estimations and assessment for pilot hole stabilization/grout filling.
With many of our larger culverts being in place for many years now we are beginning to see the collapse of culvert structures or above grounds/pavement due to under wash eroding supporting material or surrounding grounds movement. Briton locates cavity’s behind culvert walls and also provides pilot hole CCTV for volume estimation to allow accurate grout filling of voids. The development of this highly specialized system allows for reliable stabilization of culverts rather than replacement, thus offering substantial savings for asset owners.
Briton Detection & Inspection services have been trusted to some of New Zealand's leading mining, construction and government origination's to deliver void locating solutions to many challenging situations.
