Grate

1 min read Updated 6 Jul 2026 DrainSpy Brisbane
In short The slotted metal or plastic cover over a drainage inlet that lets water in while keeping people, animals and larger debris out.

Grates are the visible face of drainage: on floor wastes, gullies, stormwater pits and street inlets. Their open area is a design parameter — too little and water ponds in storms even though the pipe below is empty.

Heel-safe and bicycle-safe patterns matter in trafficked areas, and lockable grates prevent lids going missing.

What Is It For?

Admits water to drains while excluding debris and providing safety.

Where You'll Find It

On every surface drainage inlet, from bathroom floors to street kerbs.

Common Problems

  • Leaves matting over the surface in storms
  • Broken or missing grates creating hazards
  • Painted or paved-over grates reducing intake

How DrainSpy Brisbane Deals With It

A CCTV drain inspection is the standard way to confirm whether this is what's happening in your pipes: the camera shows the condition on screen, a locator pinpoints the exact position and depth, and you get a recorded report before any repair decisions are made.
