With over 20 years of experience in the construction and building materials industry, we are a company with a modern outlook and bring to the industry a uniquely versatile product with an ever-increasing demand.


Our mouldings are suitable for private and commercial buildings, historic restorations and new build projects of every scale, style and complexity.

They are designed for external use and can be made to match all stone and rendering finishes with accuracy.


Whether from one of our existing ranges or for a bespoke project, all our mouldings are carefully manufactured in our workshop to the highest quality control standards.

We offer a comprehensive service, including design, manufacture, supply and installation.


Our mouldings are manufactured through a unique combination of polystyrene and a specially formulated stone effect coating - hence the name 'Polyconcrete'. 


The polystyrene centre is cut to the desired design using our CNC machine.


The shape is subsequently coated with our unique stone-effect coating making the final product solid, durable, waterproof, heatproof and giving it an authentic stone quality finish.


The mouldings can then be painted by hand using external masonry paint or we can provide the mouldings readily finished in any render colour of your choice.


Depending on our client's requirements, we can supply the mouldings as whole units or in multiple parts for assembly on site.  


 Our unique design holds several positive material properties with respect to, insulation, fire resistance, durability, ease of maintenance and many more.
