Water under floorboards

[Thewedge55]

Approx 4 inches - starting to smell - pumped all out, dried out and then it rained!!

Its all back again, checked everything to do with drains, airbricks, water on patio - no joy......have founf a leak in the roof right above the cavity wall on the side of the house - above the area where the flooding is happening.

Could the water travel all down the cavity into the cavity under the floorboards?

First thing first is to fix the roof!

You can check the drains with drain dye, it comes in different colours. Make sure you only use one colour per drain.

Example: use one colour for the Foul (Toilet water ) sewage........& a different colour for the Storm water (rain water)

I had the same problem, water under the floor.

I got in touch with the Geological Survey. They informed me that I lived on a clay hill with glacial gravel veins running through it and one of these veins most likely ran under me house. So when it rained the veins would transmit water under my house.
Options I had were,
1, A french drain across the back of my house to intercept the water.
2, Fill my floors in with concrete.
3, Fit drainage under my house.

I went for option 3. Builder came in and fitted a trap at the lowest point which ran to my main drain. Problem solved.

Can you tell me how much this cost? I have a tarmac drive. Would this have to be dug up?

Hi Christein,

It cost me £500 about 6 years ago. I guess it all depends on where your drain runs as to whether you will need to dig up your drive.
