Bentonite vacuum excavator

Horizontal directional drilling

When executing a horizontal directional drilling, you need some equipment, such as a drilling rig, a bentonite mix- & pump system, and a bentonite vacuum excavator. The latter is needed to suck the used bentonite, or the excess drilling fluid (or sludge) out of the borehole. After this, the borehole can be closed again and the horizontal drilling can be completed.

Customized bentonite vacuum excavator

Bofram Techniek is a specialist in creating bentonite installations. With this, we mean the mix and pump units to create the drilling fluid and the bentonite vacuum excavators (also called mud suction systems) to suck the drilling residue out of the borehole. This residue can be, among others, bentonite, mud, or sand. This drilling residue can then be recycled if the customer desires. This can mean that it will be spread over the farmland. It can also mean that sand is filtered out of the drilling fluid so it can be reused for the next horizontal directional drilling.
