Dpc height around pvc door

[markus2025]

Hi guys using this image as a example if my dpc is set at the purple mark would this be a issue with the door ?

should the door and dpc be on the same line on the yellow ?

Dpc is set at internal floor height otherwise you will have a damp floor and wall.

If its a cavity wall the internal and external dpc dont have to be the same

DPC can, and if necessary should, run down and under the cill of any frame.

However I suspect you are asking the wrong question, as the is no reason why a DPC would be that high relative to the ground or floor.

I will get a picture of what i have tomorrow but basically my external dpc is say 5 bricks high and my door sill is set on the 4 the brick

Internal damp proof course on the inner skin at 1 brick from ground level not finished floor level ground level and external dpc set at 5 bricks high

This is all on a retro fit so not by new build standard this is the issue when i try to understand on here and folk talk about floor insulation there is no floor insulation as like i say its a part retro fit so im fitting a dpc but not going the whole hog and redoing all the internal floors

Text is hard to understand. Post a sketch, preferably a sectional view.

The whole point of a DPC is to stop water coming up the wall and entering the internal leaf of a cavity wall and the floor.

To that end it can go anywhere as long as it acheives it's purposes. Cavity trays are used where the internal DPC is at a higher level than the outer, and double DPCs used where the internal is lower.
