SERVICES
We specialise in the following building services.
COLUMN AND SLEEPER RETAINING WALLS


Building a retaining wall helps to create structure through terracing and support around a property. They provide stability to minimise soil erosion and offer an appealing aesthetic to balance a backyard, support a range of buildings or define driveways to provide better access.
The materials we use for all our column and sleeper retaining walls are a combination of concrete footings, with either timber or steel posts to house the sleepers and to retain the ground. The sleepers are either wood (pine or red gum) or concrete.
Combinations:
- Timber posts for timber walls
- Steel posts for timber or concrete sleeper walls
(Please note: steel posts can be powder coated to your desired colour for an extra cost)
Well designed and built retaining walls are the backbone of a landscape design for many properties.
Timber sleepers (pine or red gum)
Traditional, wood sleeper retaining walls look authentic, add natural beauty to a property, whilst providing the structure an area requires. They are functional and suit many needs, however their lifespan will vary according to the local conditions of the property.
Concrete sleepers
We recommend and work predominantly with concrete sleepers. There are many advantages to using this long lasting and durable material. Concrete sleepers are comparable on price with traditional sleepers and as they are made from concrete, they are a perfect long-term solution, as there is no need for ongoing maintenance. We can source concrete sleepers in a range of colours and patterns that give them the appearance of wood. So, you can have a traditional looking wood retaining wall without having to worry about any maintenance.
Natural stone retaining walls
The equipment we have at our disposal enables us to create a natural style retaining wall built by moving existing earth into form and then adding a range of rocks, this type of retaining wall suits rural properties as it offers low to no ongoing maintenance, whilst aesthetically it adds a natural looking flow to the area whilst serving a purpose.
EXCAVATION


We offer a comprehensive excavation service for residential and rural properties. Our knowledge and experience will ensure you feel confident in our ability and skills to work on your property accurately and efficiently.
Site cuts
We create the foundations for a building. Whether it is a new home or an outbuilding, the site is cut accurately and according to plan. We create detailed footings and get the site completely prepared for the next phase of building.
Backyards
Are you planning on creating the backyard of your dreams? To begin the process of landscaping you need a solid foundation. Our specifically designed equipment and depth of knowledge will help you to create exactly what you had envisioned. We can create specific spaces for pools, level out areas or create outdoor rooms, through terracing your sloping block. To complete the design, we can also update or create a new driveway for you, so you can utilise your whole property.
Medium density developments
Our team has the capacity to complete site cuts that form the foundation of your domestic development. We will excavate all detailed footings, drains, trenches and driveways, for medium density multi dwelling developments.
Rural properties
If you operate and live on a rural property, we understand how important it is to clear your space. We have the experience to clear and maintain drains, stockyards, sheds, or backyards, we also maintain existing dams on your property. Our experienced team understand how essential it is for rural properties to be supported and must have correct foundations created for the structure to survive long term.
With any excavation project that we undertake we clear and remove all unwanted soil so the site is completely prepared for the building phase.
Rock drilling
Do you live in an area that has high incidents of rock? Our team can assess your property to understand the type of rock that you require excavating as we custom design and make our own core barrels to suit a specific project.
We can penetrate a range of rocks including:
- Bluestone
- Basalt
- Mudstone
- Mudstone
- Granite
Just to name a few of the types of local rock / earth that we can overcome when leveling ground, building works, or creating terraces in sloping blocks.

We can cater for any building development requiring an auger or boring work with our range of drill attachments.
