Installation & Care

Before installing Volcanic Rocks, assess the site and prepare a stable base suitable for the size and weight of the stones. Plan the layout in advance, particularly where the rocks will sit near pathways, garden edges or other areas used by people.

Position larger rocks securely to minimise movement and avoid creating unstable stacks. Mechanical lifting equipment or assistance may be required depending on the weight and quantity of individual pieces. Keep rocks clear of drainage paths and access areas unless they are specifically incorporated into a suitable design.

For dry creek beds, prepare the underlying area to suit the intended drainage function rather than relying on decorative rocks alone. Periodically check the installation for movement, accumulated debris or exposed edges that may need attention.

Their 150–250 mm size range makes them an excellent option for designers and property owners looking to move beyond fine decorative stone and introduce larger, sculptural elements.
