Previous projects

Soakage holes

Hamilton Public Library.  The severe flooding of Hamilton Public Library’s parking facilities during winter months calls for the installation of soakage holes. Designed and installed by the team at Hamilton Asphalts, this sustainable drainage solution included excavation and placement of four 30,000Ltr retention tanks, backfilled by a suitably designed SUDS system. This included permeable paving to the car park surface.


The Base, Te Rapa. Foundations for a new development at The Base, Te Rapa, required the design services of the team at Hamilton Asphalt. With surface area flooding a common issue, designs were required to mitigate against rising winter water tables.


Wastewater services. We can replace damaged wastewater pipes. If you need a remedy to your situation, big or small, give us a call.  Our Hamilton Asphalts team are experienced in all things wastewater.
