Build A Step

Brendan makes round steps using concrete stormwater pipes.

Project Materials

  • 600mm diametre Concrete Stormwater Pipe (available form Rocla or James Hardie)

  • 600mm diametre Precast Concrete Paver (available from garden Life)

  • Bricks

  • Mortar mix (sand, cement, water)

  • Fill (eg rubble, bluemetal, soil)

  • Spirit level

  • Trowel

  • Wheel barrow

  • Shovel


  1. Cut stormwater pipe to appropriate length, as per the suppliers instructions. Ensure the cuts are neat and not jagged.
  2. Create a level solid base for the pipe to sit on, we have used bricks and mortar.
  3. Lay a ring of mortar on top of the brick base for the cut stormwater pipe to sit on, and leave to set overnight.
  4. Empty your fill into the stormwater pipe compacting as you go to ensure a solid finish. Your fill should be flush with the top of the pipe.
  5. Lay a mortar ring around the edge of the stormwater pipe and sit precast concrete paver on top. Wipe away excess mortar.


  • We used a steel reinforced stormwater pipe which requires a demolition saw to cut. Fibre reinforced stormwater pipes are available and can be cut with a much smaller tool.
  • Contact your local council to verify step height regulations. Generally the rise of a step (vertical height between two steps) should be between 130mm - 190mm
