Cavity Filling, Nose have a look

[staningrimsby]

we often buy bulk loads of ballast (sand 'n' gravel mixed) and mix our own concrete, as any we have left over will do the slab and fill the cavities
.

Nose i saw this remark you had put on another message, am i right in thinking here Nose that you fill the cavity up to just short of DPC level with concrete ???

 

[hotrod]

Yes, that's what he is saying (I think):-

I'm sure he will be along later to confirm

we now fill cavities to within 225mm of the dpc. this usually translates to 3 metric courses of bricks below dpc.

when i first started it was only 150mm or two courses.

incidentally, cavities are filled prior to back-filling and compacting in order to prevent the walls pushing in.

a lean mix is all that is required, usually about 7 or 8 ballast to 1 cement.

I sit right Nose that you have to be 225mm away from the DPC or can i go closer to it ???

 

[noseall]

225mm is compliant with current reg's.

why?

don't tell me you have filled right up to dpc?

 

[staningrimsby]

No m8 i havnt filled it at all at the moment, but its only 250mm from my footings to the DPC so i guess i cant fill it any more.
