Filling gap around base of external wall causing damp

Postby Don41 » Fri Dec 23, 2016 3:24 pm

We have some damp on the inside of an external wall near the front door. On the other side (exterior side) of the wall, there is a 3 inch gap in the ground around the base of the wall which appears to be filled with sand. I think this is where some of the damp is getting in to the house. I am thinking of filling this with concrete, but have read that this will stop the area of wall from 'breathing' and letting moisture out. In which case what do I fill this gap with?
