Stevensons-Stone® is a Jesmonite-based alternative to natural stone, which offers a lightweight stone effect material with the added benefits of increased impact and water resistance. Convincingly replicating natural stone, but with a fraction of the weight, Stevensons-Stone® allows for finely detailed architecture to be created and easily installed on new and existing buildings.
Stevensons-Stone® mouldings are both versatile and durable. They can offer a thin section but are not brittle. They are lighter than stone or sand & cement products and therefore can offer significant construction savings.
Stevensons-Stone® mouldings have a Class Zero fire rating with reduced smoke density and toxicity characteristics. They offer superior water and stain resistance. They are acoustically dead. The mouldings are suitable for both exterior and interior use.
Stevensons-Stone® mouldings are impact resistant and their thinner section gives a reduced cladding zone. Their lighter weight requires less expensive metal support or fixing points than their heavier alternatives.
Stevensons-Stone® can be produced with a plain white ex-mould finish or it can be pigmented with any RAL or British Standard Colour. The material can offer a smooth or textured finish.
Jesmonite-based Stevensons-Stone® is a sophisticated variant of GRC and consequently shares characteristics of GRC manufactured products as set out in GRCA (Glassfibre Reinforced Concrete Association) Technotes. The GRCA Technotes confirm that good practice is consistent with:
