Weepholes – Stormwater Kerb Outlets

Benefits

Weep holes deliver value mainly through what they prevent: long-term water saturation behind kerbs and retaining walls, and the costly repairs, waterlogged gardens and maintenance complaints that follow — see how tough galvanised mild steel holds up under that kind of sustained exposure. Giving water a clear exit point keeps surrounding infrastructure drier and reduces the ongoing burden on councils and builders managing residential drainage.

• Reduces the likelihood of costly retaining wall or kerb repairs caused by long-term water saturation
• Helps keep nearby gardens and pathways usable after heavy rain instead of left waterlogged
• Lowers ongoing maintenance call-outs for councils and builders managing residential drainage complaints

Applications

Weep holes are typically specified wherever a kerb or retaining wall holds water that needs a controlled way out: residential kerb outlets, garden beds backed by retaining walls, and footpaths or driveways prone to water tracking underneath. They’re frequently paired with roll kerb grates as part of a combined surface and sub-surface drainage approach along residential streets.

• Residential kerb outlets
• Retaining walls and garden beds
• Footpaths and driveways
• Paired with roll kerb grates
