Drainage & Ground Prep FAQs

Here are some common questions about our Drainage & Ground Prep.

What is ag pipe (agi pipe)?

Ag pipe (agricultural pipe, also spelled agi pipe) is a slotted, flexible pipe that collects ground water through its slots and carries it away — used behind retaining walls, in garden beds and across wet or boggy ground.

Do I need a sock on my ag pipe?

In fine or silty soils, yes — a filter sock stops soil clogging the slots and keeps the drain flowing. Surround the pipe with free-draining drainage gravel and wrap the trench in geofabric for the best result.

How do I drain behind a retaining wall?

Lay ag pipe along the base behind the wall, surround it with drainage gravel, wrap it in geofabric, and run it to a suitable outlet. See our retaining walls & sleepers range.

What's drainage cell used for?

Drainage cell provides drainage in a slim profile — planter boxes, green roofs, podium decks and behind walls where there isn't room for a gravel drain.

Do you deliver drainage gravel in bulk?

Yes — by the cubic metre across Melbourne, Geelong, the Mornington Peninsula and the Surf Coast.
