Sprayed Concrete - Sika

Sprayed concrete is characterized by high flexibility, good economics and good physical properties. It requires the combination of advanced concrete admixture chemistry and modern materials handling technology. Nevertheless, the advantage over conventional concreting methods is outstanding: the application of concrete without any formwork.
