Concrete Faced Rock Fill Dams

Cross section of Glennies Creek Dam showing the dam wall composed entirely of rock fill with a concrete face on the upstream face of the dam to stop water leaking out of the dam.




The start of construction of the Glennies Creek Dam rock fill embankment. A concrete "toe slab" is first built at the upstream edge of the dam wall, rock fill is then placed and compacted downstream of the toe slab to form the dam embankment. When the rock fill embankment is completed a concrete face slab is built on the upstream face. This concrete face slab connects to the toe slab to form the impermeable membrane of the dam to stop water leaking out of the reservoir.
