Damp Proofing Cellar

chris1012

We tend to get ground water leaking through the brick wall in the attached dug out which is located in the cellar.
We suspect the previous owners dug down to create head clearance without realising there was a water table underneath.
I would prefer the head clearance, so would not want to fill the hole up.

Is there any inexpensive ways of stopping the water coming through the side walls in the cellar?
Was thinking of blackjacking it but not sure if this would be sufficient and if so, which specific one should I purchase?

Thanks

If you find one patent it, you would get rich. There are methods, but they don't come cheap. Look on a cellar or basement as a reverse swimming pool. Trying to stop the moisture from the inside is a difficult job. Starting from the exterior is always the best place to start, but it's not always so easy.

It would have been dug as a drain not for head clearance, you seem to be using it just as intended, with pumps.


The normal way to tank is to lay plastic that channels the water down to a hidden drain and to a sump to be pumped away.

You'd be better off dealing with the problem from outside. Stop the water getting in - in the first place.

I live in a high table area and i had a problem with my suspended floor which is sandwiched between two extension concrete floors filling up with water in the heavy rain. It baffled me - but a small gap between my property and the neighbors was allowing the heavy rain to find its way around my concrete foundations and through this small gap

I put a land drainage system into the front and back (perforated pipe 60cm down into the ground, back filled 10mm pea gravel and connected to a down pipe gully) and that has sorted my problem.

Forget tanking and deal with the problem from where its starting.

It is ground water , so not sure that is an option?

I assumed the water in my basement was groundwater when I bought my house. It’s was actually a combination of a leaking water main and poorly designed guttering that overflows with very heavy rain sending loads of water pouring down the walls. A neighbour was quoted a five figure sum to sort out his “groundwater” problem (explained to him as a consequence of shifting watercourses). Turned out it was a cracked drain that the water board repaired for free.

Water will find its way to the lowest point but that doesn’t mean that’s where it’s coming from.
