Progress on CBD grouting plan for old mines - ABC Online


Posted January 10, 2013 06:26:44


Progress is being made in terms of developing a Newcastle CBD grouting plan stemming from mine subsidence from old workings.


Last year, maps were released showing the extensive work required to ensure buildings across Newcastle do not collapse.


Grouting has been used at several Newcastle building sites, with concrete slurry pumped into old workings, like those under the site earmarked for a new $94 million court complex.


The Property Council's Hunter Chapter Chairman Ed Crawford says grouting work is a top priority.


"We have made substantial progress in that Endeavour, and we are now moving towards the likelihood of a broadscale grouting strategy for large parts of the CBD," he said.


"That is one of the main physical constraints to development and renewal in the city, and so we're quite excited about the progress that has been made."


Other sites have also been assessed by engineers, and Mr Crawford says the data will be used for the grouting strategy.


"A citywide grouting strategy is much more cost efficient and provides the community with certainty in respect of that physical constraint being removed from large parts of the city," he said.


"So all of these proposals and development applications that we hear about and talk about that don't seem to go anywhere - one of the reasons for that is that the grouting is a problem."
