Wooden floors again!

Hi Jimmy, I am a shareholder in a company title building in the eastern suburbs and wonder if you can give me advice re a severe noise problem with my upstairs neighbour.  We have parquetry flooring and between the wooden floor and the cement slab there is only a sheet of bitumen so no insulation at all.  

During the day the noise is almost bearable but I am sometimes woken after midnight with noisy footsteps going back and forth and it is destroying my sleep and peace of mind.  We have a by-law requesting that residents use rugs, most people abide by this but not my upstairs neighbour!

I believe that floors are the Board's responsibility and have asked them how we should approach this problem.  They spoke with her once and things improved but not for long and now the board no longer wish to know about my problem.  Hoping there is something I can do before seeking legal advice.  Help!
