Hard graft, but can see the finish

Block and beam?  No!  Ground bearing slabs.  A decision that has given me sleepless nights and resulted in some serious hard graft.  We had 60 ton (that’s what we were told 🤔) of Type 1 MOT delivered and had to then proceed to get into the bays and levelled up, before compacting it.  The brickie was an arse as he should have stopped building and said “get your hardcore in and laid”.  His work was rather shit, so I knocked some of it down to enable me to get a dumper in distribute the piles to make levelling it quicker.  Building control were fine with me using grano dust as the top layer.  This compacts nicely and gives a much harder surface than sand.

 

Below are a few pictures.  Hoping to get everything finished by tomorrow.  I’ll breath a sigh of relief that it’s done and dusted.

It looks nice and tidy.  Did you concrete over a pipe there?

So they should be. Sand is often used far too thick to overcome poor levelling of the sub-base. Then it picks up footprints and other shapes which the concrete has to drag along if it shrinks while curing.

This is textbook stuff apart from a couple of things which reduce your mark to 99%. Well done. 🏆

Yes. LABC manual stated that it needed to be encased with concrete.

Thanks.  Hopefully, the 1% won't cause me to fail building inspector visit on Friday.   Keen to understand the 1% for next time 😂.   Block & Beam next time.
