We provide Geotechnical, Waterwell, Monitoring Bore & Environmental drilling services, including Over Water / marine operations for everything from jetties and marina development to pipeline approaches and tailings dams, with a wide range of equipment to meet all our clients’ needs.
Our Geotechnical Drilling services assess subsurface qualities for buildings and bridge sites, dam walls and all other types of infrastructure. We can provide Truck, Trailer, Track Mounted Drill Rigs, Barges, Jackups, Mangrove Buggys, All Terrain Vehicles (ATV) & Morookas.
Water well includes specialised services in Mine Dewatering Bores, Water Abstraction, Monitoring Bores and Production Bore installations and redevelopments. Our Drillers are Licensed Water Bore Drillers at Class 1, 2 and 3 level in WA, NT & QLD.
Environmental Drilling services can investigate contaminated sites for chemicals, leachates and gas intersections, and install all types of water wells and bores offering small footprint drilling provisions based on type of Drill Rig and restricted access requirements
