In preparation for the next stage of our building project we've been religiously rereading the Timbercrete building manual. As a result, it occurred to me that there are a few things that the casual observer may not realise are hidden inside a well built "TC" wall. Here's just three:

The Timbercrete manual recommends the use of galvanised flashing over a termite deterring coating. This structure, called a damp proof course (DPC), forms the base on which the bricks are laid.

Threaded rod
Each wall incorporates vertical threaded rods that help hold down the roof. (Note to self: holding a roof up is not usually as big a challenge as holding it down.) Each rod is a couple of metres long with a hook at the bottom so it won't pull out of the brickwork. We will have about 20 of these rods.

The bricks on every second course (or row) have a steel strap joining them together. For our 1,100 brick project we will need 300 metres of strap and about 1,400 screws to attach it.
