Interlocking Trapezoidal Extruded-Plastic Formliners

VinyLok formliners are extruded in lengths of up to 12m (40') for use in tilt-up, precast and cast-in-place concrete applications. Their unique interlocking system provides the ideal solution for projects where seamless finishes are required.


  • Seamless finishes
  • Design flexibility
  • Fast installation
  • Reduced labour costs
  • Less concrete leakage, grinding, sacking or patching

Installation is a Snap

VinyLok comes with an interlocking nailing strip, which is designed so the contractor may fasten the liner to his substrate and lock the rib over top of the fastener. This feature gives the form liner higher re-use and assures a clean concrete finish with no unsightly nail head impressions or grooves. In addition, VinyLok is manufactured from Acrylonitrile-Butadiene Styrene (ABS) — a plastic that has exceptional strength and resiliency, yet is easily cut with hand or power tools.

Design Versatility

VinyLok is available in a wide range of standard patterns and has the ability to reproduce almost any desired texture. Custom pattern designs are also welcome.


The quick installation time, together with up to 10 re-uses, minimizes the cost per square metre of material.

Prevents Leakage

VinyLok's special interlocking system prevents concrete leakage and virtually eliminates the need for grinding or sacking/patching.


Standard panel lengths from 90cm (3’) to 12m (40’) are available — eliminating the need to purchase oversized form liners, which may add to material and labour costs.
