Sandstone Retaining Walls and Stairs – Warner

Sandstone retaining walls and stairs were constructed in this project in Warner, near Eaton’s Hill and Cashmere.

B Grade Premium sandstone blocks were used in the retaining walls and Diamond Cut sandstone slabs were used in the stairs.

A number of low retaining walls are being built to tier the property so as to establish multiple platforms for future landscaping.

The highest section to be retained is over 2.5 metres so the main retaining structure is being constructed in three tiers – each one being a maximum of 1 metre in height and being set-back a minimum of 1.5 metres.
