thanks for this ill ask the builder as its all very confusing.
as any solution that gets put forward has alternative put forward because the other one is wrong .i think the builder is saying the kitchen floor has been dug down below ground level so the DPC has been compromised.
but thanks for this diagram its helpful
Rich_G-
if the kitchen has been dug below ground level then the best solution I would think would be to dig the ground level lower outside so that it is lower than the dpc and sloped so that water drains away from the house.
If you cant do that then I would have thought that so long as the french drain is dug below the dpc it should work, unless it's filling and collecting water from everywhere thats above it. Does the french drain have an actual pipe draining suitably far away from the house or is it just a ditch filled with gravel?

We are removing the bottom 6 inches of render on our house as it currently goes to ground level for the reasons illustrated in the diagram, so yeah, your basically just adding the 6 inches that our surveyor recommended removing..
apc
Wouldn't a plinth bridge the DPC ? Seems like a bad idea
