The Inca Wedge Blok retaining system, launched in November 2009, has exceeded all expectations

Current projects include La Montagne farm in Franschhoek with 30,000 blocks; stadium seating at Curro Private School in Durbanville; Softline office building in Century City, where the system has been specified for the vertical retaining walls to the basement parking area and is being seriously considered for a heritage site of important archaeological significance in the Northern Cape where a rectangular block was required to maintain the integrity of the original excavation.


The diversity of the above projects goes a long way to illustrate the flexibility of the system. In addition, the exposed aggregate sandstone finish, one of the options available, has won approval from Architects, Engineers and Landscapers alike.

The block is also available in exposed aggregate granite face, smooth-face terracotta and smooth- face biscuit.

Other features that have contributed to the success of the system is the fact that the wall can be built vertically as well as accommodating absolute right angles.
The rectangular block provides a larger planting area and the exposed aggregate finish allows for good plant adhesion, assuring rapid “greening” of the wall. Where possible, recycled sandstone is used in the manufacture of the blocks and recycled G5 sub base is specified for the founding material of landscape walls.
