WATERBORE DRILLING
Originally waterbores were the cornerstone of our drilling operations. Over the years this work has given us an extensive knowledge of the water table and aquifers throughout the entire Tasman region.
- Extensive Local Knowledge - Includes Water Table & Aquifers
- Production, irrigation & Sub-Division Waterbores
- Domestic Waterbores
- From 10 metre to over 500 metre Waterbores
ROCK ANCHORS & CONSTRUCTION
Construction drilling primarily involves the installation of rock anchors and soil nailing. These are then used to retain or stabilise the surrounding landscape prior to building.
- Drilling and Installing Rock Anchors / Soil Nailing
- Seismograph Installation
- Specialist Construction Drilling Equipment
- Portable Hydro 200 Soil Nailing Drill Rig
- Versatile Yanmar VI08 Multi-Drill Rig
CIVIL CONSTRUCTION
With over 27 years experience we have established ourselves as professional and competent workers on many civil construction projects. If an element of your upcoming project requires some construction expertise do not hesitate to contact me.
- Retaining Wall Construction
- Pile Design & Installations
- Shotcrete Retaining Walls
- Foundations & Structural Designs & Installations
- Retrofit Earthquake Proofing on Homes
- Road Repairs & Maintenance
GEOTECHNICAL DRILLING
Geotechnical Drilling (geotech) projects require specific and detailed information on sub-surface ground conditions prior to any development or building.
- Standard Penetration Tests (SPT)
- Push Tube Samples
- Coring and Logging of Bores (using logging tools and survey camera)
- Piezometer Installation
- Inclinometer Installation
