From Imminent Collapse to Stable Slope — Terrafix™ Delivers on Cape Town's Most Exposed Cutting — 20 Years On and Still Standing

When a failing cut slope on Victoria Road between Camps Bay and Hout Bay threatened to collapse onto passing motorists, the City of Cape Town turned to Terrafix™ blocks as the solution.

Following a geotechnical investigation by Jeffares & Green and M. van Wieringen and Associates, a combination retaining system was designed: gabion toe walls up to 2.5 m high at the base, with a 35° Terrafix™ block-covered slope above, topped by a concrete-lined cut-off drain. The maximum laying density of 10 blocks per m² ensured full interlock against lateral movement, while near-horizontal concrete infill walers at 5 m intervals handled the curved surface geometry. Thousands of water-wise indigenous plants were established to soften the appearance and blend the structure into the surrounding Cape Peninsula National Park environment.

Constructed by Vula Indlela Construction using labour-intensive EPWP methods, the project generated approximately 40 000 man hours of work for the local Imizamo Yethu community in Hout Bay. Construction was completed in August 2006 at a final cost of approximately R3 million.

The Terraforce® round face retaining walls at Harbour Bay Mall, Simon's Town, have been beautifully claimed by cascading creepers in every shade of green, softening the structure and bringing it to life in the most natural way possible.

Just think of all the insects and birds drawn to this little urban ecosystem!

What you're seeing isn't just happy coincidence - the Terraforce® block is specifically designed with planting in mind. When installed with the round face side facing outwards, the blocks create natural pockets that encourage vegetation to take root, spread, and thrive along the wall face.

A great example of how the right retaining wall doesn't just hold the ground, it becomes part of the landscape.

Expertly installed by Terraforce® Recommended Contractor Dassenberg Retaining Systems (Western Cape), with blocks supplied by Terraforce® licensed manufacturer Klapmuts Concrete.

Still standing strong after 24+ years!

Back in 2001, Terraforce® installed a heavy-duty retaining wall at the iconic Montecasino entertainment complex in Johannesburg and it's performing flawlessly to this day.

Here's what makes this project stand out:

· 2 700 m² face area
· 9 m average height
· Completed in just 4 months
· 25 MPa concrete foundation
· Cement-stabilised backfill & pre-tensioned geotextiles

This wall stands as a true testament to the engineering excellence and long-term durability of the Terraforce® system. When it's built right, it lasts decades.

Installed 13 years ago at Sasol's Shondoni coal mine near Secunda - and not a block out of place!

When the project engineers specified Terraforce Retaining Walls® in 2012, the challenge was clear: coal dust eliminates any possibility of plant growth, making conventional open-gap retaining walls a long-term liability. The Terraforce® closed-face system was the only logical solution - no gaps, no soil loss, no compromise.

Geofabric reinforced fill for high structures, as well as gravity cut face wall designs for lower wall heights, were submitted, accepted and constructed. The highest walls - at a 70° angle - are situated at the main conveyor feeders to the coal bunkers. In total, 2185m² of Terraforce® L11 blocks were installed.

A great day for Terraforce Retaining Walls® at the Specilink Specifying CPD event, InnovateX 2026, held throughout the day at the Coastlands uMhlanga Hotel and Convention Centre in KwaZulu-Natal!

Terraforce® was joined by representatives from licensed manufacturers Corobrik, Precast Structural Products, and Retain-A-Wall — a great reminder of the people and partnerships that make the Terraforce® network what it is.

There were plenty of good conversations across the day, with industry professionals sharing their experiences with Terraforce® products and reaffirming the brand's position as South Africa's original hollow core block system.

A big thank you to Specilink Specifying for organising a well-run event, and to everyone who stopped by the Terraforce® display — the continued support keeps the team focused on doing what they do best!

Terraforce® turns a Cape Town hillside into a hockey field.

Back in 2019, Terraforce® L Range retaining walls created the platform for the new hockey field at St Cyprians School, and with Table Mountain as a backdrop, it's hard to argue with the result.

The distinctive round-face finish of the Terraforce® block isn't just structural, it gives the wall a clean, consistent texture that holds its own visually even at this scale.

Terraforce Retaining Walls's story:

From a backyard machine to walls on six continents.

In 1979, Holger Rust started out importing wire mesh gabions from Spain. But something nagged at him - there had to be a better, more practical way to hold back the earth. So, he built a small "egg layer" machine in his backyard and cast the very first Terraforce® S block. It weighed 50kg. And Terraforce has never looked back.

The humble beginning grew into something remarkable. By 1984 the first licence agreements were signed. By the 90s, Terraforce® blocks were being made in every major South African city. Today they're produced in Canada, Australia, the UK, India, Spain, the UAE and beyond - with sales running into the millions.

What made the difference? A block that was hollow, reversible and plantable - meaning a retaining wall didn't have to be a grey slab of concrete. It could be green. It could breathe. It could grow.

Over years that followed, the Bayer Trophy, the Concrete Manufacturers Association & Certification Services’ (CMA) highest construction honour, has gone to Terraforce® eight times. In 2002, the World Summit on Sustainable Development invited them to present. Architects, landscapers and engineers on every continent trust the system.

And today? Holger's daughters Elgin Rust (Director of Accounts & Media) and Karin Johns (Director of Marketing & Business Development) carry the flame - both passionate about what this family business stands for. Different skills, same DNA: innovation, integrity, and an absolute refusal to take the easy road.
