Pocster Posted October 18, 2018 Author Posted October 18, 2018 My other thought is the water could be getting under the nearest window and running down to the other !!! So I would need to both to be certain water proof
Declan52 Posted October 18, 2018 Posted October 18, 2018 Honestly I think take it all back to the top of the concrete and break around each window and continue to remove the upstands as you have been doing. Get your architect to do proper drawings and then do as it's on these for test window 1. Create a dam with sand and fill the hole with water around the test window and observe. Let it sit for a day and if it's good then proceed with the rest. If it leaks and it's done as is on the drawing then it's up to your architect to come up with plan B. Repeat as above. 2

Yeah I did think of a dam around each one and soak will keep breaking out
Pocster Posted October 18, 2018 Author Posted October 18, 2018 Architect thinks he knows someone who does rubber . My concern is he might say he wants it stripped right back and ripped out . Then he’s starting afresh and not with a bodge .

Jeremy Harris Posted October 18, 2018 Posted October 18, 2018 Found a video showing exactly how to apply EPDM to an upstand like yours, might be worth watching, even if it's just so you know how the job should be done: 1
Declan52 Posted October 18, 2018 Posted October 18, 2018 So lots and lots of primer and nice neat cuts of tape. Easy!! Not having a dig but yours doesn't look like what's on the video. 2

Pocster Posted October 19, 2018 Author Posted October 19, 2018 3 sides exposed . Nothing at this point suggests the water getting under the rubber . What worries me now is water runs over this upstand and it doesn’t leak . But runs to the front of the site - has no where to go so pools and *perhaps* goes under my rubber extension to their piss poor attempt at the edges . This upstand once done properly and entombed in water would prove it doesn’t leak ; but somewhere else is . Still ! Try and get 4 sides exposed today and that frame off ( as @PeterW said - stuck down with structural silicone it doesn’t want to move !!!
Mr Punter Posted October 19, 2018 Posted October 19, 2018 Off topic but a nice job on the paving. What make is it?

Onoff Posted October 19, 2018 Posted October 19, 2018 (edited) A car port over the top would sort this... A big worry also has to be any long, lapped joints in the edpm covering the main sections of the roof. Almost screams "hot tar job" to me. That being said there are different grades of asphalt according to use; roof, loading bay subject to vehicular traffic, car parks obviously. Edited October 19, 2018 by Onoff

Still ; I shall continue abound !!
Pocster Posted October 19, 2018 Author Posted October 19, 2018 Right whilst not the issue a concern ! Looks like the metal frame can tear the rubber ( or I did it when removing it )
Pocster Posted October 19, 2018 Author Posted October 19, 2018 Let’s assume I was doing this from scratch ( might happen ! ) - I’m not completely sold on the rubber . What other options might be worth exploring???

Pocster Posted October 19, 2018 Author Posted October 19, 2018 Perhaps a dumb suggestion But why can’t I just pour waterproof concrete over the entire lot ( upstands in situ and protected ‘somehow’ then perhaps have coloured tarmac or resin driveway . I was always confused on where any water goes as it’s lower ( the slab ) than the entrance . So I want no water going through . Just thinking ?
Onoff Posted October 19, 2018 Posted October 19, 2018 I've never seen a roof done like this. Traditionally it was concrete, asphalt on top. Then chippings. Sometimes 2 layers of building paper and pebbles or slabs. I've seen hollow pot, straw insulation, lightagg etc. The "upside down" roof came next as I remember. Concrete, asphalt, insulation, pebbles/slabs. Fairly easy to rip up should the waterproof layer fail. Then came the exotics like Sarnafil.

But ignoring astetics why can’t I just pour water proof concrete ? ( no idea how you get a fall on it - but let’s pretend that’s not an issue )
Mr Punter Posted October 19, 2018 Posted October 19, 2018 I suggest a liquid product so that you can easily detail around and onto the upstands.
