About LOC-A-BLOC®.

LOC-A-BLOC® is a Retaining Wall construction element and is patented in Australia and other countries. The original LOC-A-BLOC® concept was designed by Mr K Bowes, who still plays an vital roll in product development and the business today.

The basic LOC-A-BLOC® construction element consists of a concrete block with horizontal and vertical hexagonal cores,with a coloured bolstered replicated rock face. A key feature of the system is the configuration,which utilises the horizontal and vertical cores or key-
ways to provide a powerful interlocking connection by concrete in-fill.

The method of construction is the blocks are dry laid,meaning no mortar is required between the courses,and once the wall is at the desired height the cores are then filled with concrete or gravel, depending on the engineering requirements.

There are three component sizes with distinct uses in the LOC-A-BLOC® system:

400 Series
Dimensions:	400mm x 200mm x 200mm
Weight:	27kg
Use:	For small, low walls, freestanding, cantilever up to 1.8m or soil reinforced up to 6m - easily constructed by hand. (Residential and small commercial applications, 25 - 32mpa)
600 Series
Dimensions:	600mm x 300mm x 300mm
Weight:	95kg
Use:	For engineered solutions on low walls with high surcharge, freestanding, cantilever, single skin up to 3m or soil reinforced up to 10m - laying by small machine. (Commercial, civil and marine applications, 42mpa)
1800 Series
Dimensions:	1800mm x 900mm x 900mm
Weight:	2.3 ton
Use:	For engineered solutions on mass gravity from 0.9m up to 2.7m - gravel fill, cantilever up to 8m or soil reinforced up to 20m - laying by a 20 ton excavator / lay rate is 1 unit (1.62sqm) every 5 minutes. (Civil and infrastructure works, 25 - 42mpa)
