Stone Projects

Alpha Structures Stone Division have a unique understanding of products like GRC & Jesmonite. The team have a great deal of experience designing and manufacturing them in both the commercial and prestige domestic market.

Depending on the application required, the type of building and environmental factors we are able to provide a broad spectrum of stone based materials to suit any project requirement, size, shape and colour. All our mouldings, panels, tiles etc… are unique and therefore we design and
manufacture them to meet your exact building requirements.

Please send your project requirements to and we will be happy to quote for the work needed to deliver your vision.

For more information on the type of stone products we use and some previous projects please read on.


Jesmonite is a very high-quality raw material that has some similarities to GRC, for instance, it is AR glass reinforced. By using Jesmonite it allows us to bring the art world to an end use in the construction industry. The finished products are equally as beautiful as they are durable, robust and of constant uniform dimension. We provide fixing and installation advice, along with setting out drawings for all products. For in-depth information on Jesmonite please visit their website

Glass Fibre Reinforced Cement & Glass Reinforced Concrete

The use of GRC greatly reduces weight when compared to cast stone or pre-cast concrete elements and maintains the same aesthetic in the
finished build. Making it more suitable on SFS or timber frame construction and where the units need to be removed from the critical path build program. The GRCA have some excellent publications to help with further understanding how GRC can be used. Their website is
