Groundwater is found in a variety of formations (such as porous sand lenses, limestone and fractured rock). To access this precious resource, a waterwell is required. Waterwells can be constructed using a variety of methods, from simple hand auger to more complex mud rotary systems, ranging in depths from metres to several kilometres. Most wells are constructed using a drill rig, most commonly tophead drive, table drive and dual rotary, employing a variety of methods including mud rotary, rotary air and percussion hammer. AMC supplies a range of innovative products, services and technical support to assist in the successful completion of waterwells from single aquifer systems to complex multi-aquifer artesian wells.
