The Construction Products Regulation (CPR) is in force in the UK on 1st July 2013.  This requires manufacturers to create a Declaration of Performance (DoP) and apply CE marking to all of their products which are covered by a harmonised European standard (hEN) or European Technical Assessment (ETA). H+H UK's products are covered by European Standards and details are given on the appropriate Declaration of Performance.

Declaration of Performance

On the packaging of our masonry products the grade of the material is clearly stated. There is also a 3 lettered code followed by a number. The Code (SRC100 for example) also describes the grade and type and gives the unit thickness. From the description and first letter of the code on the packaging, click on the appropriate grade below:
