For production of concrete products, which requires very low water absoprtion (paving stones, curb stones, decorative elements for gardens) PINKY-S also offers a supplement that is used for this purpose. Admixture which we can offer is a product of German manufacturer Rhein-Chemotechnik GmbH, and is called Plastolith HP5. When using Plastolith HP5 admixture the growth of algae and moss are greatly reduced and the amount of efflorescence and resistance to frost is improved.
