we knew that the previous owner had lifted the slabs and relaid them, but we did not know if they had been relaid on concrete, with a damp-proof membrane, or just on the original materials. Damp rising between eth slabs suggested that there was not a good damp-proof system in place, and that if there had been one it probably needed some attention.

The investigation has shown that the stone slabs were not replaced on a concrete base, and that there was no damp-proof membrane. The cleanliness of the fill suggested that it might be the original material from when the chapel was first constructed. Structural engineers from the Morton Partnership were also happy with the foundations that they could see below the gable wall.
Indications were also showed that the material was deep enough to allow for the insertion of an underfloor heating system.
