#DIYDay But not for me.

Builders are back to do the concrete slab for the base.

They'd backfilled it on Friday, so today was laying sand and getting the whacker plate on it to compact it all down properly.

Then they laid a damp proof membrane, 100mm of PIR insulation, then another layer of damp proof membrane.

Just waiting for the concrete truck to arrive to do the 100mm slab on top.

They were just laying the sand and getting the whacker plate going when I went out, came back and it's ready for the concrete.
