January 18, 20215 yr Hi I have a leak that is coming into my basement , only happens during heavy rain. Had drains checked by water company and these told are fine . They put dye into drains and nothing showed up.When drains cannot cope water over flows so I am thinking it's getting in via concrete or fissure. Any advise best way to seal from happening . Basement ceiling and walls get damp and discoulrs paint . Area is a small courtyard out back and standing water eventually drains away Any products to seal or specialist companies around to get this sorted, Thanks
January 18, 20215 yr I once had a house with a cellar that would flood when it rained. I just use it to store non-vulnerable items. We were on clay and the water would force its way between the wall and floor. If you would be best with type C waterproofing involving drainage membranes, a perimeter channel, sumps and pumps. Expensive and disruptive but effective. You will lose a bit of floor space. I am not sure what the drainage issues are but you could fit a non-return valve. More investigation needed.
January 18, 20215 yr Could you put in an extra drain/drains to help get the water away quicker so it doesn't back up and overflow. You could put in another downspout or 2 and use this to reduce the water going to each drain.
January 18, 20215 yr So it only happens when it rains heavily? what about a french drain outside to try and remove some of the water away from the building? are down pipes ok, is it an old house, sometimes cast iron splits at the back and then soaks the wall. is the guttering complete and able to take the surface area of the roof water ? I would check existing rainwater goods first then look at external ground levels, drainage etc.
January 18, 20215 yr Tell us a bit more about the basement construction, when it was built, what the current waterproofing strategy is etc. Newton have plenty of products to seal basements but you need to understand what the root cause is - agree that effective external drainage is probably the starting point.
January 18, 20215 yr Author Hi built around 80 years . Shared drains . Seems has been tanked. Drains not up to job so can not get rid of excess water. So any overflow gets in basement
January 18, 20215 yr Can you do a plan showing a rough outline of your plot showing the house position,downspouts, manholes and anything else you think that is relevant. A pencil and paper job and take a pic with your phone and post it will be more than enough.

I wanted to see if this a job for a builder or plumber or specialist. Or see if can redirect rainwater from roof to another drain.
January 18, 20215 yr Author Told that can overflow drains in courtyard up to 6 inches before it slowly drains away.bso thin Nking it finds it's way between walls .

January 18, 20215 yr The 4th picture of the opening post appears to indicate something boxed in. Could that be "pipes" where a joint has failed? Edited January 18, 20215 yr by Onoff

January 18, 20215 yr OK so forget the type C waterproofing, it is just the drain surcharging. Does this just serve your property or others? Do any neighbours have the same issue? Can you take a bit of the boxing off and see if there is a leaking joint? Can you get a firm to CCTV and report on the condition and direction of the drain?
