What footings or base do we need?
A tarmac or concrete drive
We can lay the resin-bound surface treatment straight on to an existing tarmac or concrete base. But this base needs to be single 'slabs' of pavement, with few, if any joints.
The depth of a concrete base for a strong sound footing, for instance, to park a 5 ton motorhome or caravan on, would be 6 inches or 150 cm laid on consolidated MOT.
Not flag stones or block paving stones
We can't lay straight onto paving stones or setts or
any other surface that has discrete units with joints
between each. That's because this extremely tough
resin needs a firm monolithic base or it may crack.
