Background: Currently extending out the back of the house, opening up the kitchen and dining room into the new extension. SE specified three padstones in total, 2 of 300 x 300 x 150 and the centre one as 450 x 300 x 150.
It was quite difficult to find padstones of this size, as they span both inner and outer skins of the wall. Contacted SE and he said it's fine to cast my own, should be done using 1:2:4 cement/sand/gravel.
When making concrete before I've just ordered ballast and just mixed the two, however on this occasion I did buy the individual elements to make the padstones but picked up building sand rather than sharp sand
Fast forward a few weeks and the beams are in, padstones were put in first then beams on top, relaying all bricks on top of steels since most were fairly easy to remove, rather than dry packing.
I've only just thought about it whilst reading another thread, now I'm slightly concerned that they won't be up to the job so after some advice!
I have no problem with doing any job properly, so I'm happy to prop the steels back up and cast in situ another padstone mix and try again. Thoughts?
