<p>Installation of the DriveGrid system is easy and straightforward. This involves rolling out the grid on top of the subsoil prior to the laying of a gravel base. One roll of DriveGrid is enough to cover the standard 20? x 60? driveway base. When using multiple rolls or sections of DriveGrid, the grid can be easily cut and laid with a 12? overlap. With a weight of only 57 lbs (26 kg), moving and transporting the roll is easy too. DriveGrid requires a minimum of only 4? layer of aggregate, further simplifying the installation process.</p>
