In 2016 Old Dubbo Gaol undertook sensitive heritage works to the unique wood block entrance floor.
The original wood blocks suffered from white ant attack and, over time, degraded and rotted greatly. Many of the original wood-blocks that remained had rotted to the extent that their structural integrity has been compromised, creating dangerous trip hazards as they crumbled and failed.
This project involved assessing the condition of each of the original blocks, those found in a good condition were saved and re-laid. Blocks in a rotted state were saved and will be used for display and exhibition.
New blocks were be cut, to replace rotted blocks, using the same wood as the original blocks: mature Narrow-Leaved Ironbark. The type of wood was discovered after an original block was sent to Sydney for laboratory analysis.
Originally wood blocks were dipped in tar which is now recognised as a highly toxic substance, instead we used a tar coloured wood-preservative oil which will look and act in the same way.
All blocks were laid following the original 1887 Dubbo Gaol plan.
This project was made possible through the NSW Government’s Restart NSW Cobbora Transition Fund, which was established to create infrastructure that drives economic growth and productivity in the region.
