Hardstand surfaces can be a cost effective solution for many situations.
Unlike asphalt (which is a sealed surface) hardstand surfaces are not sealed and hence are affected by weather and traffic. However with a little care they can last many years, especially in residential situations. As they are not a sealed surface, you will see loose stones on the surface.
A hardstand surface must be installed prior to laying asphalt, although it is referred to as a basecourse in this situation. We use either roadbase or gravel for as a basecourse, as the colour difference between the light grey and orange is irrelvant when they are being sealed over with asphalt.
Light grey in colour, when left as a hardstand surface this material is usually chosen in commercial situations.
Orange in colour, the more attractive option in residential settings. The gravel used is also called ferricrete (it is similar to "cracked pea gravel" but this is a different product).
Cream/white in colour. Not as preferred as roadbase or gravel if you wish to seal with asphalt later.
Thickness of hardstand
All three materials are very strong when installed correctly, the choice of which one to use is mainly aesthetic. We also choose the material to match what is already on site, so for example we usually use gravel on driveways in the Perth Hills area because there is often already a thin gravel driveway.
Residential and light commercial: 100mm thick
Heavy duty commercial: 150-250mm thick
