No matter whether you’re completing a home renovation job, a commercial landscape gardening project or working in an industrial environment, Coragulac Quarries has the products, expertise and machinery to satisfy any requirements.

Home projects and renovations

Many of our quarry products have multiple uses – our high-grade crushed basalt rock is ideal for driveways, footpaths and other heavy-traffic areas.

Red gravel is a popular alternative for those wanting to add a splash of colour to their outdoor entertaining area.

Commercial landscaping and gardening

If you want to create a stunning feature for any property, ensure optimum soil health with agricultural lime from our Colac quarry.

Crushed concrete and bricks are used to backfill retaining walls, and larger stones can be used to create landscape sculptures and other features. For added colour, choose purple-red scoria rock to create a centrepiece.

Industrial applications

Ag lime can be used in power stations to reduce emissions, while quarry aggregates create excellent pipe bedding and protect entrances to worksites from erosion and weathering.

Our crushed rock and concrete is also a common product used in road construction and repair.

If you’re looking for expertise in farm management, we also offer laneway construction and soil screening services.
