Its level is around 700mm lower than the neighbour. There is a timber retaining wall running alongside path retaining the soil, and then about a 300mm distance from that to the fence-line. The problem I was having was that due to the 700mm drop, water would seep onto the path from the neighbour's land. This would happen even a week after it had rained. The ground was predominately clay so it wouldn't absorb quickly, and therefore the path was full of deep puddles. I dug out most of the clay, replacing it with sand and blue metal and placed a socked ag line down the middle. Then put a small layer of blue metal on top, followed by a thick layer of river sand. The next step will be pebbles. Thankfully there is no more water building up there, even in heavy rain it all drains away immediately. However, as water is still coming through, some areas of the sand are visibly wet, whilst other areas have dried. There is no water pooling, and it's not sloshy to walk on. But some areas of the sand are still damp, and remain like that for days. The question is, is it ok that the sand is damp, as this is all up against the side of the house. Will this cause any issues? Thank you in advance Dampness around home is never OK because of risk of mould, rising dampness and increased termite risk.
