Complete retaining wall drainage kits — ag pipe, geotextile fabric, and weep holes — essential for every concrete sleeper retaining wall. Drainage failure is the leading cause of retaining wall failure in Australia. Don't skip it. Delivered Australia-wide.
Before ordering, read our retaining wall drainage guide — it covers correct ag pipe placement, geotextile installation, weep hole spacing, and the most common drainage mistakes that cause walls to fail prematurely.
What's in a Drainage Kit?
-
Ag pipe (agricultural drainage pipe) — slotted flexible pipe laid at the base of the wall to collect and channel groundwater away
-
Geotextile filter fabric / sock — prevents fine soil particles from migrating into the drainage aggregate and blocking the system over time
-
Weep holes — installed through the lowest sleeper course to provide a secondary drainage path at the wall face
Why Drainage Is Non-Negotiable
-
Prevents hydrostatic pressure — the number one cause of retaining wall failure in Australia
-
Required by most councils — drainage is mandated for walls over 600mm in most Australian states. Check your retaining wall permit requirements before you build.
-
Protects your entire wall system — reduces moisture exposure on sleepers, posts, and footings
