26th May 2008 

The new concrete floors are completed in the original house. 4 inches of concrete re-enforced with steel mesh was laid onto insulation bats over a damp proof membrain.

The bathroom has been formed in one of the origianal rooms using Ytong blocks (expanded concrete with high thermal efficiency)

Here you can see how I laid the PEX pipe in a continuous run to each room and used clips to fix it to the concrete base prior to screeding.

Note: I am not using insulation under the pipes as I want the entire floor slab to act as a thermal mass. The insulation is under the subfloor.
