Trial pits and hand auger boreholes
This style of investigation is extremely useful for subsidence work, small developments and new extensions to existing housing where limited access problems may occur. Although the depths of boreholes are strictly dependent on the existing ground conditions, in ideal situations a depth of six metres can be achieved. This equipment is light and portable and can be carried to the rear of houses, used for internal investigations and front garden areas where the more conventional machines cannot fit, keeping the investigation costs to a minimum.
