I came home to find that my carpet in my dinning room was wet and on lifting up the carpet I noted that the concrete floor underneath was soaked. Following some further investigation I discovered that water was coming in from outside the house penetrating down through the ground and somehow coming up through the concrete floor. I have found the source of the problem, which was a leak in the gutter joint directly above the wet area, which caused a serious ponding of the ground just adjacent to the dinning room. I am in the process of fixing the gutter, which will hopefully prevent the problem exasperating. However I am concerned that water has been able to penetrate the house at all. The house is approx 13 years old and it is a timber frame brick house.
I have never had any problem with water ingress before. However it seems to me that the DPC is either inadequate or just not there. Can anyone advise on possible solutions to prevent the ingress of water again in future.

is your oversite block and beam or a concrete raft? do you think you may have a plumbing leak IE radiator? maybe the rain water has worked its way down inside the insulation from the broken gutter. are the walls damp?

seems weird on such a new house
my guess would be a rad or pipe leak
very unlikely water is getting in from outside

The first thing I checked was the radiator next to the floor and also the dish washer and washing machine which are in the room door. My first thoughts were a leak of some sort within the house. However this did not materialise. Following further investigation I noted the really wet area directly outside the building next to the floor slab. There is about a half metre of filter material around the back of the house abutting the main wall. In an area directly below the gutter it was soaked I even excavated a small bit of the material and it was also very very wet underneath. As mentioned I have never had a problem like this before and the leak in the gutter appears to be the source.
Assuming it is the problem what my options to prevent any further water ingress are. I do not know the type of wall construction i.e block and beam or a concrete raft?

i was referring to the floor constructio not the wall. Is your path etc below the DPC?

The outside of the property is a patio with slab on top of a sand base and as far as i am aware this is above the DPC

LLL - haven't you always said that 90% of the damp problems you see, are down to dodgy guttering & downpipes?
This sounds classic - fix it and then let house dry out.
Is it ever gonna stop raining?

yes suggers either that or outside levels higher than the dpc,this sounds like a classic combo of the 2
fix gutter,reduce levels hey presto sorted!

well then it must be "bridging" where the water lays ???
