WIHA has a great diversity of equipment for execution of ground drilling. Besides hand (pulse) drilling to circa 5 metres below surface level, there is a tripod for drilling to a maximum of 10 metres below surface level. Using a caterpillar-tracked vehicle, these drillings can also be executed mechanically. For drilling to deeper levels, WIHA also has a wheel-driven drilling rig. Upon request, both affected and unaffected soil samples can be taken.
