Our Handheld equipment is a great way of being able to extract soil samples during an investigation when access cannot be gained with our Dart Rigs, due to tight access, or steep inclines. A great addition for us as this allows us to cover a range of site works that include restricted access.
The Mast Off is a similar method to Handheld, however, this also allows us to undertake SPT's should they be needed. A reasons for using this method is due to tight access for the rig, whether it be a confined area or tight access approaching the hole. This method of drilling could also be used to reduce fumes in a certain area of site works as this allows us to have the engine and tracked barrow away from the area whilst using the mast, should fume extraction not suffice the needs for a project.
