Underground Stormwater Tanks – Which is best, concrete or plastic?

Previous Next

This article covers a common question that Architects, Engineers, Builders and Home owners face when it comes to their construction project; Underground Stormwater Tanks – What is best, Concrete or Plastic Tanks?

More homeowners are choosing to install their Stormwater tanks Underground to save space and improve the aesthetics of their properties.

Residential Underground Stormwater Tanks are typically made from concrete or plastic.

Traditional thinking says concrete is strong and durable and therefore an ideal choice for Underground Tanks.  However, it is clear from instances like the Christchurch and Kaikoura earthquakes that rigid structures don’t perform well in earthquakes. Promax replaced many Water Storage tanks after the earthquake while we had no recorded Plastic tank failures.

Plastic Tanks are remarkably tough while maintaining flexibility to withstand ground movement without failure.

The Advantages of Plastic

  1. Light weight – Save money on handling and installation costs.
  2. Fast Delivery – Stock held on all standard sizes improves delivery times.
  3. Maintenance – 600mm Dia Manhole & Lid for easy inspection.
  4. Durability – One piece rotational moulding for durability for most sizes.
  5. Cost – Very cost comparative to Concrete

Promax Tanks are standardised in simple incremental capacities from 1000L – 300000L for simplicity which suits virtually all applications.

Promax Tanks are also available in standard diameters of 750mm, 900mm, 1200mm & 1900mm depending on Invert levels and site space availability.
