Concrete Facing Bricks
Differing from clay bricks, concrete bricks continue to gain strength with age, and have a higher sound reduction index.
Concrete bricks are produced to finer tolerances than clay bricks, providing more accuracy in block sizes. You’ll find all Marshalls bricks are produced and certified to D1 category (+3-5mm in all dimensions).
Our bricks have minimal soluble salts content, and the admixtures used both within the mix and on the surface of certain facing bricks ensure that bricks have minimal efflorescence. By contrast clay bricks may contain metallic salts such as sodium, potassium and magnesium, and consequently are categorised as either SO, S1 or S2. These define the maximum level of soluble salts. Find out more about the differences between concrete and clay bricks in this product comparison technical bulletin.
Marshalls bricks are manufactured by compacting under a combination of high pressure and vibration a semi-dry mix of naturally occurring aggregates, Portland cements, various admixtures, and synthetic iron oxide pigments.
Available in a spectrum of shades, all our facing bricks are through coloured, meaning any small chips or damage will show the same colour underneath as the main face of the brick.
