Our Services
Dakota Drilling offers a comprehensive range of drilling and foundation services to suit varied structural, environmental, and access requirements.
Our services include:
Steel Liners & Casings
Steel liners are essential for stabilising soil during auger drilling. We offer supply and installation of both temporary and sacrificial casings in various sizes and depths. These are vibrated into place to provide support during pile construction, particularly in loose or unstable soil.
Concrete Liners
Ideal for tight or awkward sites, our concrete liner service includes excavation, liner placement, backfilling, and compaction to Australian Standards. We ensure stable and durable support for foundations where steel casings may not be practical.
Pole Erection
With hundreds of installations completed, we provide pole erection and removal for lighting, communication, and transmission infrastructure. Our fleet includes cranes and rigging gear capable of servicing any region, ensuring efficient deployment and safety compliance.
Ragbolt Cage Assembly
We fabricate and install ragbolt cage assemblies for both piles and slabs. Assemblies can be built in our workshop or on-site for oversized configurations. We also install slab and plinth footings for various concrete foundation types.
Strengthening & Modification
We provide solutions to modify or reinforce existing foundations to support new infrastructure. This includes attaching new hardware to existing slabs or piles, repairing buried footings, and treating steel with protective urethane coatings.
Solid Rock Drilling
As a specialist drilling contractor, we offer Solid Rock Drilling services designed specifically for penetrating the toughest geological formations. Our advanced drill rigs are equipped to handle the extreme demands of hard rock drilling, delivering precision, efficiency, and reliability in even the most challenging environments. Whether for mining, geotechnical, or construction applications, our experienced team ensures accurate results and minimal downtime, making us the trusted choice for projects requiring robust and dependable rock drilling capabilities.
Dewatering
Our fleet includes pumps and tanks for dewatering services, essential for excavation in waterlogged or high groundwater areas. These systems support safe and efficient foundation works in challenging site conditions.
Earth Rod & Geotechnical Drilling
We offer small and continuous flight auger drilling for soil analysis and the installation of earth rod systems. Ideal for geotechnical studies or grounding systems, our equipment reaches depths safely and accurately.
Water Corporation Sewer Encasement
Dakota Drilling is experienced in auger drilling and concrete installation adjacent to Water Corporation infrastructure. Using compact machinery, we can operate in confined spaces and meet strict requirements for sewer encasement.
Tremie Concrete Pours
Our tremie systems allow concrete to be placed underwater or in wet conditions without segregation. The method ensures uniformity and strength by pouring from the bottom up, critical in deep or water-filled excavations.
Civil Works & Rock Sawing
Our civil capabilities include trenching and rock sawing using excavator-mounted saws. We can cut through fractured rock up to 1500mm deep and deliver trenching solutions as part of broader site development works.
Each service is tailored to site-specific needs, with flexible equipment and methods that ensure efficient and effective outcomes.
