The sub base is a critical element of any paving design intended to carry vehicular traffic as it is the main load-bearing layer distributing weight evenly to the earth below. In South Africa, installers of segmented paving blocks often overlook this element of design as it is argued by some that our sub grade (natural earth) could in certain instances be good enough to act as a sub base. Bosun however does not support this point of view. When it comes to driveways, a compacted sub base of good quality material is more important than the paving blocks themselves.
