French drain is divert land water

MillyD123

Hi all, I’d appreciate your advice. Land water is coming off this bank (see photos) and pooling at base of house. It would probably usually drain away but the water table is high from all the recent rain. I’m worried about it pooling so close to the foundations. Can’t be good right ?

I was thinking of digging out the end of the bank and installing a French drain which I can join to an shore at the back of the house

Any thoughts ? Would this work ?


Edit. Can’t seem to add photos on phone. For information there is a cut hole in the footpath adjacent to the house and water is visible in the hole. Probably 8 inches at the moment

i cant see why it wouldnt work.

Never allow water to pond/pool within a couple of metres of your founds. I seen the result of this a few years ago where a lazy builder didnt connect the rainwater gully to the storm drain which was only a couple of metres away and the foundations supporting the gable wall failed. Think it cost around 65k to have the the entire gable wall under-pinned.

€5 for the pipe and half an hours work at the time of building would have made some difference

Thanks Muffler. The house Is built 25 years now
And the water seems to be pooling under the entire foot path that surrounds the house. THe land bank slopes directly into this footpath. I’m guessing in dryer weather it drains away much quicker whereas all the rain has slowed down the drainage. Wouldn’t have noticed it only we cut a hole in the footpath to pull a cable in.

Is there still a solid amount of earth under the footpath?

Yes there does seems to be.
What depth would there normally be ? Should say the depth of the footpath equal the depth of the foundation ?

Depth? As in depth of concrete or depth to invert/bottom of concrete?

Your foundations should be 500 - 600mm below the level of the concrete path
