Construction

All the slates in our range have been successfully tested for durability, colour, strength, fire and freeze thaw. Many of our competitors use traditional concrete, their slates aren’t protected from the elements, which will expose the aggregate over time. See the example below.

Example of GRC Construction versus none GRC Construction

GRC v none GRC construction

In a recent document The International Glassfibre Reinforced Concrete Association recommend that for good quality GRC, ductile lifetimes of at least 60-80 years can be confidently expected in UK weather conditions. (Source: www.grca.org.uk).

Weight 30kgm2

The light weight construction of our slates saves on labour and timber costs, approximately 33% with our slate products.

Constructon

Our slates are constructed from Glassfibre Reinforced Concrete (GRC). Construction allows easy cutting without cracking or breaking. Our slates weather like natural slate not concrete, unlike aggregate based concrete products that can show aggregate through their surface due to weathering over time.

In a recent document The International Glassfibre Reinforced Concrete Association recommend that for good quality GRC, ductile lifetimes of at least 60-80 years can be confidently expected in UK weather conditions (Source: www.grca.org.uk).

Colour and Efflorescence COLOUR: Stone and Slate colours on this website are subject to the limitations of monitor quality and are for guidance only. EFFLORESCENCE: The phenomenon of efflorescence has been a problem to the construction industry for decades. The cause lies in the basis chemistry of all Portland cements. Efflorescence in Greys Artstone products is a temporary phenomena and will disappear over time.
