Our Products

We use a unique wet-cast concreting system because it provides the end-user with two key things: 

  • A maintenance-free surface that can weather all conditions,  

  • Free range of design expression with a wide variety of colours & finishes.

All of our concrete panels reflect traffic noise on both sides to mitigate disturbances to the property owner. The panels are also designed with the project site in mind, available in shorter lengths for easier installation. 

Additional Accessories

• Various heights and configurations are available to suit the needs of the project.
• Retaining wall panels are available where elevations may vary.
• Access doors and fire hose openings are available where required.
• Precast column covers that are placed between concrete panels, concealing the supporting steel posts.

Wet cast concrete allows for a variety of colours and finishes, including sand-blasted, exposed aggregate, acid washed and bush hammered finishes. Select the finish and wall series right for your project. 


The Vertarib Series is designed to achieve visual appeal on a cost-effective budget. The concrete perimeter rib allows for the provision of the concrete cover to the reinforcing steel, while the recessed center ensures a lighter, more manageable handling weight. Further, the textured surface will disperse the sound waves as they strike the wall, increasing the effectiveness of the fence as a sound barrier and reflector.

Vertarib Wall Series


The Palladian Series has the same noise reflective properties as the Vertarib Series, offering a different aesthetic result. The Palladian Series concrete panels are broom finished and formed with artificial masonry joints to give the same decorative appearance of block masonry within a solid panel.
