Penetrating damp can occur when the outside ground level is higher then the inside ground level, it can also come as a result of direct rain penetration.
Where penetrating damp is below the high external ground level we would carry out a process called tanking, this is applied internally at the bottom of the wall as part of the rising damp treatment.
Where penetrating damp occurs above the external ground level we would apply a water repellent called SecoTherm, to the outside brickwork, this prevents rain penetration into the brickwork and the chemical structure allows any moisture present in the wall to evaporate into the atmosphere. (A breathable membrane.)
