Hi, looking for advice please.
We bought our new home and moved in last October. A couple of weeks ago our kitchen was flooded after I accidentally left the hose on outside. It turned out to be a good thing, because we have now discovered that our DPC is actually about 1-2cm below our external ground level, virtually the whole way round the house.
Unfortunately, we have just spent a fortune having a new porcelain patio put in at the back (sticking with the original ground level from the developers). We're waiting for a response, but from what I've read online, the who external ground level will need to be reduced? Am I right?
Also, does anyone know where we stand with them replacing our patio if it has to be lowered? Will they have to replace it like for like? Thanks.
I've attached a couple of pics. There appears to be two levels of DPC but the builders said the bottom one is the proper one.
