Sneak peek: Terracing a mountainside in eZulwini, Eswatini

High up on the mountainside above eZulwini, Eswatini, Terraforce Retaining Walls® round face retaining walls are holding back some of the highest cut slopes the system has tackled to date. Built for the new International Convention Centre and five-star hotel and resort, the tiered walls reach up to 26m in height, with EFS Construction, a Terraforce® licensed manufacturer and recommended contractor, supplying and installing over 267 000 blocks across the site.

Seedling pockets built into the concrete infill mean the walls were never meant to stay bare. Years on, palms, agaves and flowering shrubs have taken hold across the tiers, with the scalloped block lines still visible beneath the growth, tying the structure back into the surrounding hillside.

The full story on this landmark stabilisation project is coming soon!

Terraforce Retaining Walls® 4x4 Step blocks were used to construct this staircase at The Regal Rose Spa in Durbanville, Western Cape. L12 blocks, flanking the stairs, form the retaining walls on either side, tying the entrance, planting beds, and pathway into a single cohesive design.

Blocks supplied by Terraforce®'s licensed manufacturer, Klapmuts Concrete / Cape Retaining Systems.

Terraforce Retaining Walls® Standard round face blocks were used to build this retaining wall in Citrusdal, Western Cape. The scalloped face gives the wall texture and softens its look along the boundary, in keeping with the rocky terrain nearby. The blocks' earthy tone works well with the patio's timber furniture and potted aloes and dracaenas, so the wall fits naturally into the backyard rather than standing out.

The result is a retaining wall that also works as a landscaping feature - functional, low-maintenance, and well suited to the space.

Service Road, Club Med Tinley Manor, KwaZulu-Natal, South Africa

Club Med Tinley Manor is the first Club Med resort in South Africa and sub-Saharan Africa, and sustainability was a key consideration throughout the development. This short service track, providing access to the resort's back-of-house services, follows a sloped and curving route, and was surfaced with Terraforce® Terracrete™ permeable pavers, allowing rainwater to filter naturally into the ground rather than run off, for an eco-friendly and flexible surfacing solution well suited to the track's changing gradient and alignment.

The blocks were supplied by TFSD Concrete Products, Terraforce®'s licensed manufacturer based in KuGompo, South Africa, with installation carried out by R&B Civils.

Terraforce® and Terracrete™ are registered trademarks.

Terraforce Retaining Walls® round face walls have been installed at the Distriliq Distribution Centre in Parow Industrial, forming part of a stormwater attenuation system for the site.

Two ponds are currently complete, with a third in the planning phase. The site sits very close to the water table, which shaped much of the design approach. One pond is built to hold water permanently, sitting below the water table, and already has around 400mm of water in it.

The walls, built with L12 blocks, were installed by Dassenberg Retaining Systems, a Terraforce® recommended contractor in the Western Cape.

Building Roads That Bring Communities Together: Terracrete™ in Rural Eswatini

Elgin Rust and Karin Rust from the Terraforce Retaining Walls® head office in Cape Town, South Africa, recently visited rural community roads in Ezulwini with Michael Toepfer, a Terraforce® licensed manufacturer and recommended contractor in Eswatini. The roads were paved with Terraforce®'s permeable paver Terracrete™, expertly installed by Michael and his competent team, and they show exactly why it's suited to steep, off-the-beaten-track access routes.

Before the blocks went down, the roads were graded into a trapezoidal shape for self-draining runoff, then finished with a 100mm G6 base layer. On very steep sections, whaler strips (diagonal strips of concrete-filled Terracrete™ blocks) were added for extra support, anchoring the paving where the gradient demanded it. Approximately 1.5km of road has so far been completed and successfully weathered traffic and storms over the past few years.

Once laid, the blocks provide a flexible lining that can accommodate some ground movement, and the large openings, covering 40% of the surface area, allow rainwater to drain straight through rather than run off. On site, you can already see grass and vegetation taking hold in the joints, helping root the paving into the subbase as the road settles.

For communities living on steep slopes and away from paved infrastructure, that combination of solid groundwork, permeability, and flexibility makes a lasting difference to everyday access, safer trips to school, easier deliveries, and homes that stay connected to the world beyond the hill.

Blocks manufactured and installed by Terraforce® licensed manufacturer, EFS Construction.

This Women's Day, Terraforce Retaining Walls® celebrates its directors, Elgin Rust and Karin Johns, who visit sites across the country and internationally, to get hands on wherever needed. From walking a wall installation to checking progress on the ground, their involvement keeps projects moving in the right direction.

Terraforce® is proud to have this kind of leadership behind its projects across South Africa and beyond.

Terraforce® Retaining Walls Support Access Road at ESCCOM, Eswatini

An S-shaped access road and parking area behind the new ESCCOM head office in Ezulwini, Eswatini, called for a retaining solution that could handle steep cut slopes of 70 to 75 degrees. Terraforce® was selected over a gabion alternative for being both aesthetically more pleasing and structurally more sound.

The project made use of Terraforce® L12 Rock face blocks across 890 square metres, totalling 10,600 blocks, with a further 224 square metres of base blocks built in situ below ground using 2,600 blocks. Walls were constructed as a single-skin, concrete-reinforced system up to 2m in height, transitioning to keyed sections beyond that point, with soilcrete (a 3% soil-stabilised concrete mix) used wet within the blocks.

Groundwater veins on site presented a construction challenge, requiring careful management throughout the build. Construction ran from September 2022 to November 2023.

Bongumusa Magutshwa, facilities manager, expressed that the client was very happy with the completed result: "We love the rock face finish chosen and how the walls add to the overall aesthetics of the building and surrounds."

As Terraforce®'s licensed manufacturer in Eswatini, EFS Construction supplied the blocks, and as the brand's recommended contractor, also carried out the installation.

Terraforce Retaining Walls® blocks offer a distinct advantage over other retaining systems: they are available in three finishes, are hollow and therefore fully plantable, and their shape allows wall designs to incorporate sharp or gentle curves that easily follow any slope's natural contours.

Making full use of these features, TD Contractors in Esperance, Western Australia installed Terraforce® L11 blocks in charcoal, rock face finish facing outwards, with a central curvature and three partly feathered terraces. The result is a gorgeous backdrop for a lush green lawn and a paved firepit cove.

Steps leading to the first terrace were built directly into the wall design, also using L range blocks, tying the whole structure together seamlessly. Blocks supplied by Terraforce® licensed manufacturer by The Block Makers, Western Australia.
