No such thing as a "typical" width and depth as it's entirely dependent on the wall construction / thickness and ground conditions.

That said, it would not be unreasonable to expect to find a 600mm wide strip @ 1000mm (or more) deep.

If you can elaborate on your circumstances, I'm sure you will get some more focused replies.

I would say 1m depth by 600mm wide is a fairly typical excavation, though not absolute.

The thickness of concrete within the trench can vary also, but usually needs to be a minimum of 225mm thick for a single story extension. More often than not we would mass fill a trench as it is financially better to do so.

I think a raft is typical for sand soils and piles typical for made up ground.

Don't plan on any typical foundation until you know what the typical ground conditions are

For a minute there, I thought you were being a bad man; then I came to the realisation that you actually meant it!

Thanks for the replies, but my question didn't ask for what depth the footing is located at, but merely the typical width and depth of the footing itself.

Isn't "depth of the footing" and "depth at which the footing is located at" one and the same? icon_confused.gif

Totally untrue!

I represent that remark.

I think he meant the actual foundation dimensions, rather than the depth at which it's formed. Could have been unequivocal about it though icon_lol.gif
