Sierra Delta Power Earthing is a reliable business offering deep drill earthing and light excavation services. We also perform earthing upgrades for both new and existing electrical installations that are located underground or overhead. We service rocky areas and provide excavation and trenching works. We also do pilot drilling for vertical or angled pole holes. At Sierra Delta Power Earthing, we make use of specialised equipment when installing earthing systems for safety and efficiency. We have a 4WD support vehicle and a 4.2-tonne mini-excavator that is used for trenching wires. Our support vehicle is used for transporting supplies and crew to local sites where the earthing systems will be placed. Our deep drill earthing service is inclusive of picking up plans and supplies from your depot. After our deep drill earthing work, we do resistance readings and documentation which will be sent to you for reference. Visit or call Sierra Delta Power Earthing today for a quote!
