Soil Nail Drill Rig

Equipment for soil nail drilling and wall anchoring

TMG's new Soil Nail Attachment is specifically designed to install Self Drilling Anchors (SDA) from R32-R51. The soil nail attachment can be ordered with multiple configuration options, including several drifter sizes and power pack options. The attachment can be mounted on a human lift basket or directly onto the arm of an excavator.

The drifter drilling head comes with an injection or flushing system, which can be used to inject grout, water or air.

The Soil Nail Attachment can be ordered as a complete set, including the basket, soil nail attachment and power pack, or can be ordered separately.
