We originally developed two designs* of large-unit interlocking hollow blocks, known as MACRO blocks. These are manufactured for use in the construction of agricultural or industrial retaining walls. Additionally MACRO blocks have been utilised in the construction of aggregate storage bays, retaining walls, temporary barricades and low walls into which temporary fencing can be inserted.
MACRO blocks can be built up with or without mortar between the layers. The voids can then be left empty or filled with aggregates, soil or reinforced concrete, depending on the application and whether the structure is temporary or permanent.
MACRO blocks can be installed using a lorry-mounted crane fitted with a block grab, or a fork truck or a crane equipped with a grab suitable for moving blocks around sites.
Macro blocks are manufactured using 7.3 N/mm2, 1900kg/m3 oven-dry density concrete mix.
Two-void MACRO blocks weigh approximately 550kg each, while four-void macro blocks weigh approximately 625kg each.
MACRO blocks have vertical scoring which breaks up the expanse of concrete and helps disguise the joints between the units when built.
Four-void MACRO blocks are designed to aid splitting along their length using a 300mm diameter diamond blade disc cutter and a bolster chisel.
* additional designs could be created depending on the degree of demand.
