Concrete/Stone Coatings & Additives
Our concrete additives are extremely well suited as hydrophobic concrete-additive for the manufacturing of paving stones, concrete slabs and prefabricated concrete elements. They improve concretes compaction, regulates the capillary properties of the concrete and reaches a durable reduction of water absorption. The final product is protected against rising moisture. They protect the concrete against limeefflorescences and against the growth of micro-organisms in the product (moss, algae, fungus) The final concrete-product remains vapour-diffusive. They minimises sticking to the stamp and sticking to the concrete-mixer by using a highly-effective non-stick additive.
