Overlay Vs Dig Out – What’s the difference?

Depending on the existing surface and structure of your project, we will either lay resin directly on top of it (after intensive preparation work) or we will need to dig out the existing surface and replace with hardcore material (Type 1 MOT) then lay permeable tarmac before finally, laying the resin bound surface. Note, full dig out is required on grass and sometimes existing concrete or tarmac to ensure the current base will be fully stable before laying the resin bound surface.
