Stepoc.
Stepoc is a system of concrete shuttering blocks that are highly-engineered and dimensionally coordinated.
Stepoc is filled with concrete, which is pumped down through the inter-connected cavities in the blocks. The blocks unique design creates a cascade or waterfall effect which ensures a smooth filling of the pumped concrete, forcing out air and eliminating segregation, to create walls which have immense compressive and lateral strength.
Stepoc enables the fast construction of single skin retaining walls up to 4.0 metres high, subject to a design carried out by a structural engineer. It can be filled in a single pour from 1.8-2.25m depending on block thickness. Stepoc is available in three widths, 200, 256 and 325mm and at less than 20kg per unit.
