We offer a system of protective coatingsMarwil®. Through surface and deep injections this system system seals and strengthens concrete structures by forming anti-corrosion, antifungal and algae static barrier and provides it with additional properties, such as a smooth and hydrophobic surface resistant to the effects of weather, chemicals, gasoline, etc.
A mobile device Sulspray® enables application of coats on ready elements such as: plates, roadway edge elements, curbs, tubes, bridge objects, etc.
