Newly laid tarmac is at greater risk to damage in its early life before the surface hardens over time. This risk is greater particularly in the Summer months when temperatures are at their highest. Damage can be caused by the use of ladders, standing vehicles such as caravans, motorbike stands etc.
Although any damage can be repaired, often the repaired areas can be obvious and spoil the overall appearance of the surface. This damage can be avoided by the use of boards under ladder feet or caravan / bike stands.
