You know the sound. That rattle every time a tyre hits a stormwater grid. It is not just noise. It is a warning sign, and LiBER GRIDS silences it for good.
KLAK-KLAK. It is what you hear when you drive over most stormwater inlet grids at shopping centres, garage forecourts, airports and pretty much anywhere a traditional stormwater grid has been installed.
But a rattling, klakking grid is more than a nuisance. It is:
A safety hazard for vehicles and pedestrians
A theft risk, because loose grids get lifted and stolen
A flooding risk, because worn grids fail when you need them
A sign the grid is grinding itself to failure
LiBER GRIDS is on a mission to stop the KLAK-KLAK.
Why Grids Go Klak: It’s Not Age, It’s Physics
STAGE 1
The Impact
When a grid sits just 2mm below the road surface, every tyre that slams into that leading edge creates thousands of kilograms of dynamic force. That kind of loading is a death sentence for traditional grids.
STAGE 2
The Grinding
Loose grids and sand work into worn seatings, creating a sandpaper effect. Every passing car grinds the metal down. The gap gets bigger. The rattle gets louder. The KLAK-KLAK becomes a permanent resident.
STAGE 3
The Dishing
Traditional iron gets tired, loses its shape and sags. We call it dishing. The moment a grid loses its structural integrity, it can never be silent again.
“At LiBER GRIDS, we solve the physics.” — Francois, LiBER GRIDS
The fix
How LiBER GRIDS Silence the Klak‑Klak
Flush by Design
Grids sit flush with the surface, so tyres roll over instead of slamming into a leading edge. No impact, no damage, no noise.
Precision Seated
Machined seating means no loose contact points, no sandpaper effect and no grinding wear from passing traffic.
Locked Down
Our patented locked-in design means grids cannot lift, shift or be stolen. No movement under load, ever.
The result: 25 years of guaranteed silence. ISO 9001 certified. S355JR hot-dip galvanised steel. No more KLAK-KLAK.
