Pocster Posted November 24 Share Posted November 24 Ok - stop laughing that’s the 1st thing . The ongoing saga continues- due to the storm etc has got a bit worse understandably. So the glazing does not leak . I believe water is getting in outside the plot running down the wall and getting in over the concrete slab . If you look closely at the glazing you can see water comes in only above the concrete I.e dry as a bone above this . I need to ( one day ! ) dig up the lane side outside that wall and try and fine any gaps -fill with cement . But of course - that’s not a guaranteed fix . So in reality I think I need a 2nd ceiling ( above tiles - below cables ) with the sole purpose of directing water towards the edge ( dimpled membrane on wall leading to perimeter drain ) Take any suggestions how to do this ! . My 1st issue is how to make a ‘tray’ that sits around the base of the Lightwells and directs water into a ‘ceiling ‘ membrane . Obviously once I think I have a solution I’ll empty the room , take down the tiled ceiling . So I’m thinking of a simple ‘wedge’ structure . The membrane sits in this ; and as it has a fall directs water to the outer wall . Its what I do around the sky lights that’s got me a bit stuck .

Pocster Posted November 24 Author Share Posted November 24 The 2nd photo is a sky light just outside the electrics cabinet . New line of water tracking in its direction !!! . So I wedged some membrane up with a fall to at least direct any drops outside the electrics room …. 1 Link to comment Share on other sites More sharing options...
Pocster Posted November 24 Author Share Posted November 24 @Thorfun - this is in the utility room so not the main underground living area . So no need to be to sad 😊🤣 Link to comment Share on other sites More sharing options...

joe90 Posted November 24 Share Posted November 24 (edited) Really difficult to suggest a solution but might a little dam of silicone bead to stop the water tracking where you don’t want it then it should drip into a container or somewhere it won’t cause trouble. emoji was not meant to be sad but “what the feck do you do?” Edited November 24 by joe90 1 Link to comment Share on other sites More sharing options...

Seems to work sometimes. It’s the Lightwells I’m unsure what to do with . Need to have water drip into some kind of channel around them that direct the water into a membrane . Not an easy thing … Link to comment Share on other sites More sharing options...

joe90 Posted November 24 Share Posted November 24 I made some small guttering for a little outhouse here made from 32mm drainage pipe cut in half and glue gunned together, or a funnel glued there with a pipe attached 🤷♂️ 1 Link to comment Share on other sites More sharing options...

Leak is somewhere below the base of it I.e concrete slab below there . But even when I dig that up - fill what I can - it’s no guarantee of a fix . 1st glazing unit is approx 1m to the left inside wall . Link to comment Share on other sites More sharing options...

But it’s how I ‘fix’ it to the membrane for a waterproof connection. Think I need to make something under the larger glazing ( easier access ) and simply use the professional approach of trial and error ! Link to comment Share on other sites More sharing options...

joe90 Posted November 24 Share Posted November 24 Ground will always be damp, DPC needs to be continuous outside of any concrete. Can you dig up around the skylight and waterproof the outside of any concrete ? Link to comment Share on other sites More sharing options...

Can you dig up around the skylight and waterproof the outside of any concrete ? Thats a big “ not possible “ . There was zero dpc in the design . So that wall sits on the edge of the concrete slab . As water runs down it and goes below the ground ; I believe it’s finding gaps ( between slab and wall ) and simply running there . So I do need to dig up that edge in the lane ; presumably just go along and smear cement on the edge I.e down from wall base to over the edge of concrete slab .

Pocster Posted November 24 Author Share Posted November 24 So just to clarify . Wall sits on edge of slab . I’m certain ‘here’ is the point the waters getting in and then running across the slab until of course it finds an exit - the Lightwell . Link to comment Share on other sites More sharing options...
Pocster Posted November 24 Author Share Posted November 24 I know I need to dig up along that lane . But on a blustery wet Sunday decided to look at the drips and procrastinate . Link to comment Share on other sites More sharing options...
Kelvin Posted November 24 Share Posted November 24 I know you’re sure where it’s coming from but have you proved it to yourself by using a hose on the window side to see if water comes in or not? Link to comment Share on other sites More sharing options...

Yes . Zero leaks if I do that . Look at photos you can see water line is on concrete slab - none coming through above I.e upstand etc .

Russell griffiths Posted November 24 Share Posted November 24 @Pocsteryou can get various products for sealing porous ground, one is called bentonite, it is used for sealing up voids in clay when used to build the sides of a lake if it’s leaking. I wonder if you can find something that you can dril a few holes in the ground and pump it in under pressure to find its way to the gaps and cracks. just a thought. 1 Link to comment Share on other sites More sharing options...
