I just don't like concrete on the edpm; and I have to have that to spread the car load and protect the insulation. If I get a leak in the future I'm right back at square one ripping the whole lot up. If the edpm is exposed (apart from parking area) then it's accessible for repairs; thats got to be better surely?

Anyway!; I've thought about this more. Potential plan. Rip all out back to rubber Remove rubber (I suspect that isn't possible) without damaging vac insulation under cement board. New Rubber roof ; easy enough to test Shutter 'parking area' Pour concrete in parking area (reinforced presumably) Pavers on parking area to fall for slope. (I know architect was concerned if this 'wedge' of concrete would spread the car load enough (after-all I'm trying to avoid concrete on rubber)) Stilts either side for pavers and walk on glass. 2 issues I can think of Would the stilts damage the rubber if they are sat on them with pavers above being walked on? No 'fall' is made in the side 'stilted' bits so water could pool. (Stilts have to be set on flat ground)

No chance. Was an important party of planning consent.

Hmmmmm How do I make a ‘fall’ in poured concrete ......?

The roof make up was (top down ) pavers 35mm reinforced concrete rubber particle board vac insulation 100mm reinforced concrete But I think that’s all going to change !

Spoke to the architect- my idea has merit ! And yes @PeterW I could duck about around each window and never find the leak(s). Assuming I rip the lot up back to the rubber . Will the rubber come off the cement particle board ? . If not would a proper rubber roofer be happy to rubber over the top of existing rubber ?? Worry the ‘stilts’ will dig into rubber . My architect is adamant water proof concrete doesn’t exist ?

Brainwave attack ! Centre of plot I.e where you park waterproof concrete whatever To the sides stilts ! Then walk on glass is effectively not going to be ever submerged ! - same on other side !! As long as you park straight ( not that we are ever going to park on it anyway ) Does THIS have some merit ? ( feeling very smug )

What about the ‘pavers’ on stilts idea ?. Assuming you can get a system you can drive on ! . Could even have a pump below the stilts for drainage . Whats this system actually called ???

Just for completeness. Here’s the front effort they left me - i’ve Not touch this . When I flooded the site no water went over these bits as it’s fair too say they’ll leak . Enjoy quality !!

Yeah it’s probably not possible. 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 )

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 ?

Just quickly googled it ; says a single ply system - no ply for me ?

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???

Right whilst not the issue a concern ! Looks like the metal frame can tear the rubber ( or I did it when removing it )

Yeah Any joints a potential issue ! Still ; I shall continue abound !!

Lol Wish the paving was shit and it didn’t leak ? Think it’s marshalls metro line

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 !!!

Oh I do ! I remember his “receipt “ said “ all work guaranteed “ - what ? To be shit and leak ffs ! I’ve only had 2 ‘professional ‘ trades on this project - both shit ; ?

My backs telling me to stop ?

Yep I’m certainly not doing it ! ?

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 .

Yeah I did think of a dam around each one and soak will keep breaking out

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

Can’t see a ‘vote’ option a) attempt patch b) rip up and start again ( at mercy of ‘roofer’ )

I seem to recall the issue was it’s lack of flexibility especially when concrete is poured ontop . Architect ‘s call
