How to use this section

Observe the pattern before choosing a fix

A photograph of the whole area, details of when the issue occurs and information about previous work are more useful than a close-up alone.

Look beyond the damaged spot

Check nearby edges, drains, walls, covers and wheel paths. A dip or crack may be the first visible sign of movement that follows a trench, weak boundary or water route across a larger area.

Record weather and loading

Note whether the symptom changes after prolonged rain, frost, parking or heavy delivery vehicles. These patterns help distinguish drainage, support, material ageing and isolated impact damage.

Avoid masking the evidence

Do not seal an unexplained crack, fill a moving joint or pressure-wash unstable paving immediately before assessment. A quick cosmetic treatment can make the original cause harder to trace and may need removing again.

Choose the guide that most closely matches the first symptom, then follow its links to the relevant repair and prevention options. More than one issue can occur together—for example, settlement can create standing water, while water can accelerate joint loss and movement. The site assessment should therefore consider the connected defects as one system.
