Sub-bases Pavingexpert

As described above, sub-bases are exceptionally good at spreading or dissipating a load, and it is this feature which makes it almost impossible to properly compact any thickness of granular material more than 150mm deep. So, for a 250mm sub-base, two layers @ 125mm could be used, or one layer @ 150mm and one @ 100mm.

Subgrades and Subbases for Slabs Concrete

22-11-2017  Place a concrete floor on an unstable subgrade or subbase and you’ll probably pay for it two ways. During construction you’ll either waste concrete or end up with a floor that’s too thin in spots because the subgrade/subbase is uneven. After construction, the floor is likely to settle and crack because of poor subgrade/subbase support.

Sub-bases Pavingexpert

The sub-base layer is often the main load-bearing layer of a pavement. It is designed to evenly spread the load of the paving, and any traffic thereon, to the sub-grade below. A well-constructed sub-base will aid drainage and prevent settlement and channelisation - the phenomenon common on cheap installations of block paving, where two 'ruts' develop in the paving.
