Concrete spraying is an excellent tool to stabilise and support structures in a very short time and for concrete applications using any moulds. Concrete spraying is also the interaction of man, machine and concrete. Sprayed concrete is a high-performance material which only works as well as these "three ingredients for success". Man, personified in the work of the nozzleman, requires great technical skill and dedication to the job. The operator must be able to fully concentrate on the machine and the sprayed concrete. It is the interaction and quality of these elements that determine the success of the concrete spraying application.
In times of rapidly increasing mobility and limited space, the need for underground infrastructure continues to grow. Sprayed concrete plays an important role in this regard. This method is economically advantageous and almost unlimited technically, making it the obvious answer.
Against this background, Putzmeister and Sika have formed a global strategic partnership for concrete spraying in tunnelling and mining. This partnership ensures that our customers benefit from innovative ongoing development of concrete spraying machines and admixtures for very high demands in the highly-mechanised installation of sprayed concrete.
