I have laid an Indian sandstone patio which is the required level below the damp course of the house but I now wish to build steps up to the French windows. Can anyone advise how I should do this without bridging the damp course. I could just leave a gap between the house and the steps but I am concerned that this will fill up with leaves etc.

Breaching the Damp Proof Course
A common query, since we set up this site, has been the potential risk of creating problems with rising damp if the step rises above the damp proof course (dpc) to tie-in with internal floor level. In 99% of situations, a 'hollow' step of this type represents no real threat, as the amount of brickwork in direct contact with the wall of a property is minimal. A solid step, ie one cast in concrete, or where the 'hollow' is filled with a concrete or other fill material, can be isolated by incorporating a damp barrier between the step and the wall. Filler board or a plastic/vinyl barrier is suitable, and can be sealed on the external face with a silicone or polysulphide mastic sealant.
For more information on DPCs and paving/drainage, see the Dealing with DPCs page. refer to this on main index
