The tiles have been sealed from above with a concentrated cement wash and a steel chassis has been put in place to prepare the section to be concreted.

Two 16mm steel bars run the length of each beam and on top of that a mesh of steel of lighter gauge will distribute the load across and down to the ring beam sections for this whole of this roof section.
2 types of concrete are used to fabricate the slab. One type is firstly placed on top of the beams essentially covering the wood and uses ·arlita·, sintered stone light weight pellets to reduce the weight and load on the beams.
The roof is then covered with conventional gravel based concrete which is used to cover the roof and prepare the base to receive the roof tiles.
