Mechanically Anchored Concrete Liner Systems
Mechanically anchored lining systems provide long-term concrete protection for infrastructure exposed to aggressive chemical, wastewater and underground environments.
Unlike traditional coating systems that rely solely on adhesion, mechanically anchored liners become integrated into the concrete structure itself.
The result is a durable, chemically resistant and watertight lining system engineered for predictable lifecycle performance.
Cast-In Systems
For new construction projects, mechanically anchored liners are fixed to formwork prior to concrete placement. During the pour, thousands of integral anchors become embedded within the concrete structure, permanently locking the liner into place.
This creates a robust protective barrier that becomes part of the asset itself rather than sitting on the surface.
Cast-in systems are commonly used in:
Sewer tunnels
Wastewater treatment plants
Pump stations
Drainage structures
Marine infrastructure
Chemical bunds
Retrofit & Rehabilitation Systems
Existing infrastructure can be rehabilitated using post-installed mechanically anchored lining systems. In these applications, liners are installed onto prepared substrates and fully encapsulated using specialised grout systems.
This approach allows ageing infrastructure assets to be upgraded and protected without complete asset replacement.
Retrofit systems are ideal for:
Existing sewer infrastructure
Concrete rehabilitation projects
Pump station upgrades
Tunnel remediation
Chemical containment rehabilitation
All lining systems are extrusion welded to create a continuous, homogenous and watertight protective barrier.
Every weld is tested to ensure quality, consistency and long-term integrity. This eliminates common failure points associated with traditional applied coating systems.
The result is a lining system designed to withstand:
Hydrostatic pressure
Chemical attack
Moisture ingress
Abrasion
Live concrete cracking
Fully Welded Protection Systems
Designed for Lifecycle Performance
Infrastructure protection should not be viewed as a short-term maintenance solution.
Mechanically anchored systems are engineered for service lives exceeding 100 years in non-UV environments, dramatically reducing future maintenance requirements, recoating cycles and operational disruption.
For critical infrastructure assets, long-term lifecycle performance matters.
