Effects and Uniqueness of Concrete

Concrete, this outstanding and inimitable living matter

Concrete is a material that is worked in an artisanal way. Pur Béton’s handcrafted pieces have unique effects and more or less prominent marks from one another. Although each element is manufactured with great precision, no two parts are identical. Each one has its distinctive features, variations and charms..

Effects and uniqueness of concrete: What you need to know The efflorescence, surface heterogeneity, porosity, hairline cracks* and mould markings are integral parts of the material.  This is what differentiates it from industrial and synthetic products. The effects and patina that concrete items take on with age and use are in no way manufacturing defects. *Hairline cracks may develop through the expansion and shrinkage phases that concrete undergoes during curing. These microcracks do not cause parts to break. They are superficial, sometimes visible and generally non-absorbent and barely noticeable to the touch.
