RETROFIT STORMWATER SOLUTIONS

Upgrade Failing Grids With a Safer, Stronger, Zero-Maintenance System

Introduction To Our Grids

Protect Your Property with a Retrofit Solution That Actually Works.

LiBER GRIDS provides a high-performance retrofit drainage system designed to replace broken, noisy, rusted or unsafe grids without requiring costly reconstruction. Whether your current system is collapsing, clogging or causing flooding, LiBER GRIDS retrofits deliver immediate improvement and long-term performance for commercial, residential and mixed-use properties.
Built for durability and engineered for high flow and load-bearing performance, LiBER GRIDS give you a permanent fix, not another temporary patch.

Why Properties Need Retrofit Drainage

Ineffective or aging stormwater grids create recurring risks:

Drains collapse under vehicle loads

Water overflows into walkways, parking areas or building edges

Rusted or stolen grids leave open channels

Pooling and channel blockages damage paving and foundations

A proper retrofit system brings your drainage back up to standard; restoring safety, protecting infrastructure and preventing repeated failures.

What Sets LiBER GRIDS Apart

1.Engineered Flow Performance

The structural design and large surface area promote rapid water capture and dispersion, ideal for preventing pooling at entries, driveways and paved areas.

2.Designed for Real Load Conditions

Retrofit grids are specifically developed to cope with everyday vehicle movement, cars, SUVs, light delivery traffic or heavy load traffic without bending or popping out.

3.Locked-In Stability & Anti-Theft Security

The integrated frame and grid system prevents uplift, shifting, rattling or removal. Once installed, the system stays firmly in place.

4.Zero Maintenance, Long-Term Reliability

Unlike standard retrofit solutions that rust, loosen or clog, LiBER GRIDS require no ongoing maintenance once fitted.

5.Consistent Quality Assurance

Every grid is built under strict quality controls, giving property owners the confidence that their drainage system will perform year after year.

Choosing the Right Retrofit Drainage Solution

Before upgrading a failed grid system, consider:

Flow & Capacity Requirements

A retrofit should be sized to handle rainfall volume, driveway slope and runoff intensity to prevent overflow or backflow.

Load Class

Retrofit systems must withstand the vehicle types using the area. A driveway, retail parking or delivery zone each require different load performance solutions.

Material & Durability

Long-lasting materials prevent cracking, rust, noise and ensure the system performs through weather changes and traffic cycles.

Safety & Stability

A retrofit must stay firmly locked in under load. Loose or rattling grids introduce liability risks and can damage tyres or create trip hazards.
LiBER GRIDS retrofit products are designed to meet every one of these criteria with a balanced blend of strength, stability and longevity.
