With rail constructions in a recess it is often desirable to fill up the spaces between the rail and concrete safely with (frost resistant) material that keeps the recess dirt and water free. The qualities of the rail construction have to be maintained and the crane wheels must not be obstructed by it. In total it must be safe and may not cause stumbling danger. Traditionally the spaces in the recess can be filled up with lean concrete or mastic asphalt. However, neither system functions optimally under all circumstances.
Bemo Rail has developed material on the basis of rubber liquid-mortar. This rubber liquid-mortar is elastic, non-shrinkable and remains compressible. It consists of rubber granulates and a two-component liquid mass, on the basis of reactive polymers. The upper 25 mm of the rubber liquid can be applied in a different ratio, so that a denser, watertight structure is developed that also adheres very well to steel and concrete.
