LiBER GRIDS, a specialised division of LiBER CIVILS, is showcasing its approach to smarter and more resilient urban stormwater infrastructure, with its patented flush-by-design drainage system aimed at addressing common challenges associated with conventional drainage grids.

The system has been engineered to eliminate the “klak-klak” noise typically associated with traditional stormwater grids. According to the company, the noise is caused by physical gaps between drainage components, which can also contribute to rattling and structural wear over time.

Security is another key feature of the LiBER GRIDS offering, with the system incorporating a proprietary lockdown mechanism designed to prevent theft and unauthorised removal. Tamper-proof sheer-nuts are used to secure the grids, effectively removing what the company identifies as a persistent vulnerability in conventional infrastructure.

LiBER GRIDS says its products are designed to provide municipalities and property developers with high-performing infrastructure that combines durability, security and reduced noise in urban environments.

The company backs the system with a 25-year structural guarantee, while its products are supported by ISO 9001 and SABS certifications.

The development comes as municipalities and developers increasingly seek infrastructure solutions that can withstand demanding urban conditions while reducing maintenance requirements and improving public environments.

By combining a flush installation design with enhanced security and long-term structural durability, LiBER GRIDS aims to offer an alternative to conventional stormwater drainage infrastructure, particularly in applications where noise, vandalism and theft remain concerns.

LiBER GRIDS Head of Operations Francois van Niekerk spoke to Engineering News & Mining Weekly during the Electra Mining Africa event, held in Johannesburg from September 7 to 11, 2026.
