If that pebbledash is fixed with cement-based render and/or painted in non-breathable paint then it's a sure fire way to ensure the damp walls will never dry out properly.
This is good advice. Pebbledash can also be problematic when it cracks too. Can pay a specialist (I think they are called Mahon in Leytonstone) to remove it and re-point at a later date.
cheers mate.
Main thing seemed to be paving being too high and they recommended a bell drip finish.
