Technical Information

Standards:

Stone by Design LTD's GRC Architectural Cast Stone meets the very highest of standards BS 1170 part 5.

 

Cement Efflorescence:

As with all reconstructed stone cement-based products, the temporary phenomenon known as efflorescence is likely to occur. It sparkles. It's white, sometimes with a grayish tint. It flakes off the surface and is present only on the surface. It's a crystalline deposit of salts often seen on the surface of concrete, brick, stucco or natural stone surfaces. It occurs when water leaves behind salt deposits and is present on or in the masonry surface.

 

Effloresence is in no way damaging to the product. This effect reduces over a period of time with natural weathering.

 

Manufacturing Tolerances:

Dimensional tolerances permitted by BS 1217: 1997
