What Causes A Pothole?

There is no agreed definition of a pothole. The cause is either ‘top down’ or ‘bottom up’.  A ‘top down’ is a localised fault that develops into fretting and becomes progressive. A ‘bottom up’ failure results from a fault at depth usually involving the presence of water which causes cracking and usually leads to a block of material breaking away as the  surface of the road  weakens and expands aggravated by the weight and impact of traffic. However, the definition of a pothole is not agreed between all local Highway Authorities which can cause some issues. However, the team at Cycle SOS can advise you at every step of your cyclist pothole claim.
