Heavy traffic, delivery lorries and what they do to tarmac
A surface that carries cars all day wears differently from one that carries lorries. Turning wheels scuff the top layer, and the heavy axles of delivery vehicles press into soft areas, creating ruts, cracked edges and patches that sink. Retail and trade sites around the borough often see all of these in a single yard.
Water makes it worse. Rain finds a crack, softens the base underneath, and the next wave of traffic breaks the surface open. Catching damage early usually means a patch or a seal, while ignoring it can mean lifting and relaying a whole bay. We look at the base as well as the top layer.
