Dam Building Services
Overview
Engineered Earthworks for Rural, Agricultural, and Industrial Dams.
At Oldknow Earthmoving & Haulage, we bring decades of experience to the design and construction of earth dams across rural, agricultural, and industrial properties throughout NSW. Whether you’re building a new stock dam, upgrading for water storage, or restoring an existing structure, we offer a practical, engineering-backed service that ensures long-term strength and functionality.
From small farm dams to large catchment basins, we’ve got the gear, the crew, and the local knowledge to do the job correctly—and safely.
Our Dam Construction Services
- New dam builds – Complete dam construction, including site clearing, excavation, shaping, and compaction.
- Dam enlargements and upgrades – Widening, deepening, or raising existing dams to increase capacity or meet new water requirements.
- Desilting and cleaning out – Removal of built-up silt and debris to restore volume and improve water quality.
- Embankment construction and reinforcement – Engineered embankments are built with appropriate materials, moisture control, and compaction.
- Spillway and overflow design – Installation of properly sized spillways and diversion channels to manage overflow and protect the surrounding land.
- Inlet and outlet pipe installation – Fitting of control structures for water flow, including penstocks and poly pipe setups.
- Seepage control and clay lining – Lining dams with clay or suitable materials reduces water loss and improves retention.
The Right Equipment and Operators
We use purpose-built earthmoving equipment, including dozers, scrapers, excavators, and water carts, to ensure the right moisture content and compaction during construction. Our machines are GPS-capable for precise shaping, and our operators have extensive experience in working with varied soil types, slope stability, and water movement. All dams are built to suit your land’s natural contours, rainfall patterns, and water use requirements.
Engineering-Driven and Council-Compliant
For larger or regulated works, we work in partnership with licensed civil engineers to ensure designs meet council and Water NSW guidelines. If you have existing plans or require a site assessment, we’re happy to collaborate with your consultant or help you connect with trusted professionals.
