Sill Plate On Outer Walls?


I guys wonder if somebody can help me out abit?

Im going to be building a timber garage for a friend and i have got a lad to concrete the pad for me, i have always been taught whilst working in NZ anyway that the sill should hang about 10mm over the pad on the external walls im not saying this is correct it is just how i was taught.
The concreter has disagreed saying that all the company's he works for ask for the pad to be 100mm bigger than the building which seems strange to me. Just wondering what the normal practice for you guys is? Maybe we are both wrong.
I would look in my books but as im currently moving i have only just packed them up.
Thanks
Chris

I was taught to make the plate flush with the foundation wall. Once sheathing and siding are applied, you actually wind up with an overhang.

But building practices vary around the world, and what's considered proper here could (and obviously does) conflict with the way things are typically done in other areas.

Yes usually wall should end up being flush. You definetly don't want the wall to be in from the edge of the slab, you will eventually have rot problems. Of course don't just go off the concrete either, chalk some lines and read the plans and adjust accordingly.

Re: Sill Plate On Outer Walls?


Cheers guys. As i said i was taught to aim for around 10mm overhang and so have just stuck to this. Like you say though i never just go off the slab so it isnt always 10mm it depends how good the slab is.
Good job i checked his measurements before he poured it as 100mm too big would have been disastrous i have never known anybody do this, though he does slabs for a company who install log cabins and he says that is what they ask for.
This is my first timber frame in the UK and so want it to be spot on as im hoping to pick up more timber frame work from it as there isnt anybody in my area doing it.
Once again cheers guys

Agreed. Flush to slab. My only difference
Is here, we use a sill flashing/termite shield. It gets sealed to the concrete and has a 45 degree downward break. Then the framing goes flush to the edge of the slab / flashing break. This helps prevent the sub terranean termites.

We don't do it in Utah and I didn't do that in las Vegas or Texas. All I've ever done is either use sill seal or a bead of glue under the plate. (sill seal sucks)

We do it here also sometimes.... But not so much anymore, we just keep the slap up from the dirt and a rock border all the way around the house.

Sill seal is awesome to install on windy days, all kinds of fun, whatever do you mean?

I'm with you on ending up with a overhang, no way would I have the pad 100MM bigger, just makes no sense to me but call up your building official and just ask he will be able to tell you your codes there for something like that in 2 sec.

I thought millimeters was only used in Canada anymore? Dang Canadians pushing their measurements, its becoming an epidemic.

Most countries use the metric system.
