Depth of reinforcing mesh

[Arnold9801]

I'm pouring up the foundations for our new build tomorrow with a c25 mix.

 

I've had to put some reinforcing mesh in certain parts and have lifted them about 50mm above the floor.

 

Is that ok?

Probably.  About in the middle of the concrete is good so if the slab is 100-150mm thick it is fine.  Why did you put mesh in the foundations?  Not normally needed (but it won't hurt).  Good luck with the pour.  Much concrete?

Reason for the mesh was due to me having and old soak away trench going right across the new build. 

 

Building ctrl wanted me to dig all the way down to the bottom of these trenches where the foundations cross them. This caused the sides to cave in resulting on large holes 10 feet deep. I had to fill these up to just below the floor level of the trenches. The mesh had to go over the top of this concrete in fill and overlap by a foot the trench floor.

 

Thanks for your reply.
