The Granitgard system of graded stone, strip shielding and Blockaid is a unique combination of environmentally friendly products that provides simple and effective termite protection in almost all building situations.

Granitgard stone barriers were first used in 1990. Since that time, in excess of 150,000 new buildings have been safely treated by the hundreds of Granitgard installers who service most cities and regional centres of Australia. Granitgard barriers are also widely used for protection of extensions to existing buildings.
