Hey Is there just a thing ? Tried to make one - wasn’t too good ? I’m looking for something that allows a perfectly straight cut - not easy when cutting a paver with a full sized angle grinder . Thought there might be a ‘guide’ like you get with a circular saw - but it appears not ...

It’s not clear too me at all if these pedestals can ‘slope’ the pavers I.e allow for a sloped paver .

Architect recommended rubber roof guy coming to look next week . Watch him laugh ☹️

Yeah i think the architect wants the ‘parking area’ to have a raised kerb at the edges . You could still drive over it ; break the tile and stilt then embed your wheel in my rubber roof ?

I think I have a solution . Agree that the edpm protected is best - but nice to be able to find a leak and get to it if an issue . One thing I never liked was the water running level with the glazing . The stilts offer perfect drainage solution for that . This stilt on edpm is used ( forgetting vehicle’s ) plenty of examples for terraces / roof gardens etc . I guess the edpm could be ‘protected’ via some other means ; or perhaps a thin layer of concrete . That way edpm protected . Stilt sits on thin concrete layer . Glazing has zero drainage issues - water can never get that high . When I break back to the 35mm concrete - obviously this will be damaged and cratered . It could then be screeded with a fall to the front and a ‘channel’ made in the form work . Rubber over the lot means even the channel gets water proofed and is built in . This sounds like all requirements are met ; yeah ?? ?

I take your point . Most likely failure point though must be edges / flashing . Also the stilted solution means no water at skylight level - skylight never gets swamped in water . Trying to solve multiple problems with this scenario ?

If exposed edpm gets damaged I thought it could be fixed / patched ?? After all that was the original plan on the upstands

This is my main worry now and water at skylight level . The solution I have solves those issues . Some thought on falls and drainage make it do able . No way am I concereting over rubber . Even if it was leak free I don’t want to be posting back here 20 years later I have a leak . I want my rubber to be like any other roof I.e I can get to it

The architect originally wanted the pavers bed in concrete for extra waterproofing ☹️. This still puts water level potentially flush with sky lights although you say a drain . Surely the stilted pavers mean the skylight glass never gets water anywhere near the top .

If I have a new rubber membrane over the concrete that’s great . But I still have to make the fall and bed the pavers in concrete - therefore covering the rubber in concrete again effectively. Draining under the stilted slabs is the issue ; due to no fall . That needs to be solved somehow .

Pedestrian; but that’s ok ; only need it to the sides of my parking bay

Just found that the company that do those feet also do a protection mat deliberately to stop it damaging the rubber . Good news .

I agree again 100% But I’d have to break out 35mm of reinforced concrete ( and there is a risk I could damage the rubber ) . Equally as you say I could damage any new edpm with a new concrete pour - I’m then back at square 1 . I’d rather have a rubber roof that can be serviced . You are probably right I know that . But I’d sleep better with a new rubber roof that can be accessed if any issues . I don’t want to hear that drip drip in the night .... ?

Agreed But I’m still unhappy with a potential leak in the future . I’m want my rubber roof accessible. good workmanship seems to be in limited supply

I think I’m well beyond finding the leak ! The particular glass I dug around seems ok visually . Can’t trust ANY of this rubber is best !

But @JSHarris what do you think of my hybrid solution?? ?

The parking area is the real fly in the ointment!!

https://www.wallbarn.com/adjustable-plastic-paving-support-pads/ I *guess* it would be best to make the fall on the existing concrete under the new rubber layer . Not sure how to do this . Next issue would be what it drains to . I guess if a fall can constructed so can a gulley .... just thinking out loud ! ?

Probably not. But I'm hardly going to risk it. You saw the quality of their work - better not to rely on it even if there are no leaks. If I follow @PeterW suggestion I'll effectively have 2 rubber layers (1 I don't trust; 1 I do trust) - also saves me removing 35mm concrete. Also solves the load spreading issue with the vehicle ?

Will the up stands not sit next too each other with a rectangular long paver like mine is that the issue? It's not a real problem if thats correct - I can re use these pavers elsewhere (not above the dwelling) Ok; it's a thought. There's no way I can get the pavers off the concrete without damaging it. What's the best way to patch/fill the damage 35mm that sits above the old membrane? Pavers are bed in concrete - wasn't allowed sand!

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 !
