CE Marking


As you may be aware,the Construction Products Regulations 2011 (CPR) include a requirement from 01/07/2013 that all products manufactured to a harmonised European Standard carry a CE Mark and an accompanying Declaration of Performance (DoP).

For cast stone it is true to say that both the industry as a whole and the trade association UKCSA have been divided in their interpretation relevant to the CE marking of cast stone products. At GreconUK we have determined that certain cast stone items (ie. those with a maximum dimension of <650mm and that do not contain fixings or reinforcement) fall under the BS EN 771-5: 2011 Manufactured Stone Masonry Units standard, and as such require a CE Mark and associated DoP. Typically these are items such as Quoins and Ashlar Blocks. It is important to recognise that bespoke precast units (ie. those products not made to a harmonised European Standard supplied to a single customer's specific requirements for delivery to a specific project [or defined number of projects], and not be placed into the open market) must not carry a CE Mark.

This applies to the vast majority of our own precast and cast stone products. For clarification these units will, where relevant, be supplied either to an agreed bespoke specification or to a non-harmonised standard eg. BS 1217:2008 - Cast Stone.
