Hi folks, looking for some advice please
I'm currently refurbishing a 1970's dormer bungalow and have been working top down - the house is watertight etc. But i do still need to put up guttering at the rear.
After clearing out the rubble from underfloor and drying everything out I'm finding damp in the concrete slab under the floor. De[pending on how heavy the rain is there can be a trace of surface water. It seems to come from the vent built into the brickwork on the inner wall.
Hard to tell where it comes from but there is no sign of damp/water above the dpc on the wall and only appears after rain.
My thought is rainwater is seeping in through the brickwork below the dpc.
Should I worry? and if i should what do i need to do?
The house is built on a concrete slab which is solid and in good condition.
