In modern infrastructure projects, precast concrete pipes are widely used for drainage, sewage, and industrial applications. However, these pipes are constantly exposed to abrasion, corrosion, and chemical attack, which can reduce their service life. The V Lock Concrete Protective Liner provides an advanced solution to extend the durability of concrete pipes, offering long-lasting wear protection and cost savings for pipeline owners.
A V Lock protective liner is a specially designed HDPE or PP sheet with V-shaped anchors that lock securely into the inner wall of precast concrete pipes. During the casting process, the liner is mechanically anchored to the concrete structure, creating a permanent protective barrier between the concrete and the transported medium.
Abrasion resistance – protects against wear from sand, gravel, and slurry.
Corrosion resistance – withstands harsh chemicals, acids, and wastewater.
Long service life – significantly extends the lifespan of precast concrete pipes.
Mechanical anchoring system – the “V lock” profile ensures strong bonding with concrete.
Smooth surface – reduces friction and improves flow efficiency.
The V Lock liner system is widely used in:
Precast concrete sewer pipes – for municipal drainage and sewage networks.
Industrial concrete pipelines – handling corrosive or abrasive fluids.
Concrete manholes and chambers – protecting structures from chemical attack.
Water treatment facilities – ensuring durability in aggressive environments.
Compared to unlined concrete pipes, concrete pipes with V Lock protective liners deliver:
Enhanced durability – resisting both chemical and physical damage.
Lower maintenance costs – reducing repairs and replacements.
Improved safety and reliability – ensuring stable performance in critical infrastructure.
Versatility – suitable for sewerage, drainage, mining, and industrial projects.
Material: HDPE / PP protective liner
Anchoring: V-shaped locking studs for secure installation
Application: Precast concrete pipes, manholes, tanks, culverts
Protection: Abrasion, corrosion, and chemical resistance
The V Lock Concrete Protective Liner for Precast Concrete Pipes is a proven solution for ensuring long-lasting wear protection in demanding environments. By combining the strength of precast concrete with the durability of a V Lock lining system, infrastructure owners can achieve extended service life, reduced maintenance, and reliable performance in sewage, drainage, and industrial applications.
