Sprayed Concrete Lab test
Analyzing tunnel core samples in the Burghausen applications lab to determine the sprayed concrete's waterproofing properties and its strength increase over time.
Polymer-modified concrete is sprayed onto the walls in the Stetten salt mine to stabilize the tunnel and to act as a barrier to water seepage. The innovative formulation reduces the rebound during spray application, and so minimizes waste and material consumption.
