From Pit to Paradise: Why One Homeowner Said No to a 12m Concrete Wall
Cape Town's Kanonberg Lifestyle Estate presented a classic challenge, a steep, unusable embankment threatening to leave a homeowner literally living in a pit. The solution? A stunning multi-terrace retaining wall system using Terraforce® L11 blocks, installed by Decorton Retaining Systems, a Terraforce® Recommended Contractor.
Contractor S.P. van Blerk crafted a series of undulating terraces with grassed platforms, outcrops, and integrated stairways - transforming an unstable slope into a fully usable, accessible outdoor space. Every terrace was engineered with its own foundation, drainage system, cement-stabilised infill, and geofabric reinforcing for long-term stability.
The finishing touch? A lush Moroccan-inspired garden by Helmut Henstock of Gardening Adventures with creepers, tree aloes, ponytails, and indigenous plants softening the walls into a flourishing, textured landscape.
The alternative? A stark 12m concrete wall. We know which we'd choose!
