Surface Drainage Swale

Surface Drainage

  • Under drains / French drains
  • Bubble basins
  • Vegetative leaching swales
  • Perforated leaching fields
  • Rainwater detention structures and “green” cisterns
  • Large and small leaching systems

Drainage is crucial to any landscape design.

Plan your drainage carefully and install prior to your landscape elements for a long lasting and effective landscape design.

We always encourage the use of indigenous and water filtering plant species which will require less maintenance overall.


Why not turn rainwater into an asset and help preserve the environment at the same time?

Ask us about roof leader cistern systems and other water conserving means to reduce dependence on groundwater reserves for irrigation.
