Bricklaying & Repointing

Damp course has been completly covered when repointing.

Anonymous user 03/03/2024 - 3.22 PM

I was told by workmen working on my housse that my damp proof course needed re pointing. It was well weathered and exposed. The pointing completely covers the damp course now. I have since been told by a family member that they should not have completely covered the damp course, that the pointing should be above and below leaving the membrane exposed. He said that the mortor needs removing as it bridges the bricks so woud percolate to the bricks above the damp course. Would someone advice that this is the case and that it needs rectifying. Update I've been told that the repointing of the mortar over my damp course is ok and that the DPC (slate) does not need to be visible. He told me that it has been water proofed. He pointed out that my neighbours house has motor all over the damp course. Do I stick to my guns and ask that he does it again?

Are you a tradesperson and able to answer this question?

The Dpc simply stops moisture travelling up the brickwork. The Dpc should be bedded on mortar, then a course build off the Dpc, you should have a clear edge of Dpc sticking out of the course unbridged by mortar.

As with D and A Complete Services By pointing the dpc layer it then creates a bridge for damp/cold to cross to the courses above; it should protrude slightly on the facing, that said i doubt it would be enough over time to really cause any issues on the external face.
