Before installing the planks a sub-floor had to be laid to create a level platform onto which we could nail our flooring. Each joist was levelled off with an axe, or padded up with wooden chocks before the weatherproof boarding was laid. Each plank was laid in position, marked, cut with a chop-saw, and nailed down.
