Niagara Reservoir, NSW Public Works & Gosford Council

IN MARCH 2016, GROUND STABILISATION SYSTEMS ASSISTED THE GOSFORD COUNCIL IN PREVENTING FURTHER WEATHERING AT THE NIAGARA RESERVOIR.

Niagara Reservoir is a 13mL, 37.2m diameter x 12.3m high prestressed concrete reservoir constructed in 1980. It is surrounded by sloping embankments and heavy vegetation. The upper rock strata are heavily vegetated, and the lower strata are weak, deteriorating stones.

On the upper area, GSS removed trees that were smaller than 200mm in girth and installed soil nails with a TRM.

On the lower weak seam, shotcrete was installed with drainage to prevent further weathering.

NSW Public Works were extremely happy with the outcome.
