Tests generally fall into 4 categories, test pits, trenching, boring and in situ testing. Test Pits Test pits are much like you would expect, a pit is dug either manually or with an excavator in order to reveal the subsurface conditions to the depth desired. Generally, this is for siting shallow foundations. Trenching

The LS100 and LS200 drill rigs are mud rotary rigs at the small end of the range of drill rig sizes. Advantages: Because the borehole is kept open by the pressure of the drilling mud, it is not necessary to use a drive casing as with cable tool drilling. Mud rotary drilling is also much faster than cable tool.

Rotary drilling rigs utilise high levels of torque and rotation, with a drill bit at the end of the drill pipe rapidly rotating (between 50 and 120rpm) and boring through the rock formation. The drill bit tends to come in two primary forms: firstly, roller-cone bits, and secondly, fixed cutter bits. Both drill bits see similarly high levels of ...
