Raised Patio - DPC needed?

[chewymix]

Hi

We recently had a new kitchen extension completed and was signed off by BC and everything is present DPC wise for the new walls. Part of the build a patio was created, thats tiled, at the same height as the kitchen floor which is around 10 inches about ground level and so above the DPC of the building. The kitchen has bi-folds onto the patio and in front of the bi-folds is a drain sunk into the patio but on either side of the bi-folds there are the brick walls, reclaimed old stock if it makes a difference, and this in total is the full width of the patio.

Everything seems(ed) fine but with all this recent rain i have noticed that the lowest 2 or 3 courses of the bricks either side of the bi-folds looks like water could be wicking up the brick ad it looks a darker colour that the rest of the wall. Is this an issue and should another DPC have been put in place at the height of where the patio is for this wall that faces onto the patio as in my mind the DPC on this wall is too low for the new 'ground' level.

Thanks for any advice

cheers

With the fashion currently for the level thresholds there are lots going in that are wrongly detailed and could lead to problems.

Was this work completed before BC signed off? They should never have approved it if so.

To do it properly there are various ways and if you know what your doing its quite easy to do in a new extension. Trouble is most builders simply build the house as normal and then think about the patio after and trying to detail it correctly after the building is up is a lot more difficult and complicated.

A surveyor would pick this up should you ever come to sell.

Any chance of a photo?
