Civil Services


From our daily business operations to our project delivery, Commons Plumbing (NT) strives to reduce, re-use and re-cycle wherever possible. We have the plant and equipment required to not only excavate but condition, back-fill and compact all works to specified density levels, including excavators up to 35 tonne, loaders, backhoes, trucks, water cart, rollers, crushing and screening attachments, which are also available for wet hire with skilled operators. This provides additional benefits for the client, as it reduces stockpiling and transportation of waste or otherwise unusable materials.
