SHughesNI Posted September 16, 2020 Share Posted September 16, 2020 (edited) hi The builder has turned up on site and isn't able to complete the foundations as in the drawing mainly due to the concrete being delivered tomorrow and feels too late to figure it out now. As I have had numerous let downs this is the first builder who has turned up when they said they would so my happy face is staying on no matter what happens. Question - Instead of doing the 40mm drop as in the pics he's going for a straight 9m x 9m foundation. How is this going to affect the overhang? Does anyone know of any clever way to enable the 40mm reduction before the pour tomorrow (Thursday) morning? If no one does is there any way after the pour I can reduce by 40mm both in the porch and the roller door? Any help would be appreciated. 445 Base.pdf 445 Elevations.pdf Edited September 16, 2020 by SHughesNI add docs of setup Link to comment Share on other sites More sharing options...
Mr Punter Posted September 16, 2020 Share Posted September 16, 2020 It would be normal to use shuttering to stop the concrete flowing into the area where you don't want it. 40mm is not very much. If you post the drawing and a picture of the excavation someone may suggest the simplest way. 1 Link to comment Share on other sites More sharing options...
PeterW Posted September 16, 2020 Share Posted September 16, 2020 Do the pour and let it start to go green. Then you need to dig out the excess down by 40mm, and put a piece of wood either side and level between. Get a sheet of polystyrene insulation and weight it down between two bits of wood that mark the gaps you need. 1 Link to comment Share on other sites More sharing options...
Temp Posted September 16, 2020 Share Posted September 16, 2020 Just cut some 40mm thick timber and screw to the shuttering. Would take me 30mins. 1 Link to comment Share on other sites More sharing options...
markc Posted September 16, 2020 Share Posted September 16, 2020 The builder should be able to sort that while waiting for the concrete to turn up, or while leveling and finishing is in progress Link to comment Share on other sites More sharing options...

He said the concrete would flow back . I am going to try it anyways. Whats the worse that can happen? (noy going to tempt fate here but check back in 2 days and you might just find out ?)

Not sure how you can nail the 40mm timber to the shuttering. See image Link to comment Share on other sites More sharing options...

Mr Punter Posted September 16, 2020 Share Posted September 16, 2020 You can shutter the verandah bit off completely with 6 x 2. Concrete either side, with one side 40mm lower then remove the 6x2 before the concrete completely goes off and infill the gap. Threshold would be easier to just scape off when it has set a bit. This is not that hard to do. 2 Link to comment Share on other sites More sharing options...

SHughesNI Posted September 16, 2020 Author Share Posted September 16, 2020 (edited) To be fair after having been let down by at least 3 builders in the last 3 months (post covid) I am grateful he is here at all but know what you are saying.

Rmawdsley Posted September 16, 2020 Share Posted September 16, 2020 Looks like he needs a bit more stone in to bring up the levels, can see a lot of day light under them shutters! Link to comment Share on other sites More sharing options...
