So with the hardcore and sand down and consolidated, in goes the 1000 gauge DPM sheet which is incredibly thick and the 100mm of insulation board with any gaps filled with sticky expanding foam to complete our floor insulation.

I’ve laid some 3×2 timber onto the insulation for two reasons, one to give me a rough depth for pouring the slab, the other to provide a channel for the services into the new build.
I arranged for the concrete to be delivered with a pump so it wouldn’t break my back with the wheelbarrow and save a hell of a lot of time.

Here is the freshly poured and floated concrete slab that Tim (Carley’s Dad) very kindly helped me rake and move around into position. The concrete guys were out the front having a smoke whilst the concrete was just blasting out everywhere so we had to work pretty fast to stop the place being overwhelmed.
I used a big blue float to get it smoothed off, it was the first time I had ever used one. Took some getting used to. Not sure how level it’s going to be as I have never poured and smoothed a slab before.

Couple of days later and the slab has hardened off and I have started to build the inner leaf up a bit.
