Premises 7
All windows and doorways now cut and removed. Larger pieces were cut around to perimeter and then knocked out using a pecker attachment on a digger.
As the concrete was cast in layers we were able to break this down into moveable chunks.


View from southwest window, looking in. The internal walls were lined with 100mm sand and 100mm Marland brick.

This didn’t perform any particular function for our use and took up 150 sq ft of space so they’ve been removed. (half the gained space will be lost again when the walls are insulated).

The remaining brick shows the level for the suspended beam and block floor.
View from the loading doorway situated between to two tanks.


The concrete roof was cast in sections around a framework of steel girders.

Where the sections join some moisture has trickled in forming stalactites.

The outside of the roof will be covered by a one-piece rubber membrane.
12mm thick bitumen lines the whole of the inside.

Despite the fact that until recently the whole structure was underground, the walls are bone dry.
Due to the roof construction it’s not possible to join the sections of the old tank internally, and the dividing arches are too low.

We’ve put a doorway into each section to give separate units each measuring approx 250 sq ft.

This tank appears to have been built at two different times, in “pairs” (dates unknown)

The oldest being at the eastern end of the site with the next pair being added later but in the same style.
There was approximately 30 cubic metres of water in the “Gothic” tanks. This has been pumped out providing an excellent test for the soakaway drain system.
Waste not, want not!

Hardcore created from the doorways, and the brick lining of the “new” tank is used to raise the floor level to create a useable storage area.
