Deco or decomposed granite is finey crushed and a compactible type yellow/golden granite. Quite commonly used in areas where a firm surface is required but left exposed like driveways or pathways where a more visually appealing finished is required..
Commonly deco can be stabilised by mixing in cement at a ratio of around 8:1. (8 Deco : 1 Cement). Stabilising creates a stronger and more durable finish while still leaving a permeable surface and gritty rustic texture. Cement can alter the colour, so choose wisely. Often an Off White Cement is used to minimise colour change.
