The mechanics of rail behaviour under load from cranes and trains needs to be understood and Weber have provided solutions in this field for over 30 years. A wide range of specialist grouts are available that can resist the high dynamic loads and provide durable long term effective use. Ultra rapid setting grouts for repairs and reinstatement have also been developed.
There is no generally accepted international specification for the installation of rails and their bearings. Installation procedures are usually recommended by the manufacturers of the rail and plate systems. The bearing grout should provide: flat, uniform, and void-free bearing surface; resistance to dynamic loads into the base material; adequate absorption of imposed loads; and transmission of bearing loads into the base material.
Typical problems during application can be attributed to poor design, inadequate mixing of grout, ambient temperature, placing procedures, slow pouring/pumping, inadequate curing.
After application, there may be challenges due to lack of Effective Bearing Area (EBA), shrinkage of grout, too high strengths leading to brittleness, inadequate HDT and water sensitivity.
The surface of the concrete base must be free of any loose, friable material, be dry and free of dust and laitance and be sufficiently mature not to interfere physically or chemically with the bearing grout.
Ensure the shuttering is made of durable material, grout-tight, well-sealed to the base and coated with a suitable release agent.
For high static loads: Choose precision grout, webercem advanced precision grout or webercem advanced precision grout SP.
For vibration, chemicals, or high dynamic loads: Use precision epoxy grout, webertec EP pourable grout.
When pouring the grout into shutters from one side of a baseplate, use a removable hopper to provide an adequate head of grout.
