ALL UNDERGROUND EARTHMOVING

Heavy Equipment for Every Project

At All Underground, we are able to meet your mechanical excavation needs with our various excavators and plant combination options. If you are looking to move large amounts of earth quickly, our fleet of excavators is ready to assist — saving you the time and energy that comes with manual digging. Our technicians have over a decade of experience using various forms of excavation equipment on job sites of all types and sizes.

These versatile excavation machines can be used for almost any digging project, ranging from landscaping and fence footings to earthwork excavation projects such as establishing foundations, building demolitions, and basements.

Our Excavator Fleet

All Underground has the excavator to suit your needs and budget, with a wide range of excavator sizes and plant combination options available for hire. When you hire an excavator from us, we can also supply a skilled operator to run the machine.

Micro & Mini

1.7T - 3T • Perfect for confined spaces, landscaping, fence footings

Medium Compact

5T - 6T • Trenching, small earthworks, residential foundations

🚜 Mini Excavator Hire + Hydro Vac Combo

For smaller excavator units, we can team a micro or mini excavator with hydro vacuum excavation systems. This combination provides an excavating solution perfect for small jobs in difficult-to-access areas where buried utilities are a concern.

🛡️ Locating Underground Assets First

Should your site contain buried utilities, All Underground can first perform non-destructive digging (NDD), vacuum excavation, and utility mapping to locate assets before mechanical excavation begins — preventing costly strikes and delays.

Frequently Asked Questions

Choosing the right size depends on your project scope, terrain, and accessibility. Micro & Mini (1.7T-3T) are ideal for confined spaces like landscaping or fence footings. Medium (5T-6T) suits trenching and small earthworks. Large (8T-15T) handles bulk earthmoving, demolition, and site preparation. Our team can assess and recommend the best fit.
Common methods include trenching (linear excavations for utilities), bulk earthmoving (large-scale material removal), benching and battering (sloped excavations for stability), and foundation digging. Each method uses specialised attachments and techniques.
Excavators (crawler and wheeled), backhoes, bulldozers, and front-end loaders are common. At All Underground, our excavator fleet ranges from 1.7T mini units to 15T production machines, with quick-coupler attachments for versatility.
We provide bulk earthmoving, site preparation, trenching, foundation digging, demolition support, landscaping preparation, and hard dig removal. We also combine mechanical excavation with hydro vac potholing for utility protection.
Tracked excavators perform well on soft or uneven ground (mud, clay, loose soil). Wheeled excavators suit hard, stable surfaces. Our team evaluates your site conditions and selects the right undercarriage and machine size for optimal traction and stability.
Manual excavation uses hand tools (shovels, picks) and is slow, labour-intensive, and suitable only for small, shallow digs. Mechanical excavation uses powered machinery to move large volumes quickly, safely, and efficiently — essential for construction-scale projects.
