TERRAFORCE IS CELEBRATING 45 YEARS OF FAMILY LEGACY AND RETAINING WALL EXCELLENCE!

Terraforce pioneered the hollow, reversible interlocking retaining wall system that is unmatched in versatility, both in application and elevation in 1979. The wide range of plantable interlocking retaining wall blocks is tailored to create environmentally friendly domestic or industrial installations and to support sustainable development in soil stabilisation. The block retaining walls can range from light gravity concrete retaining walls to geogrid reinforced earth-retaining or heavy gravity, double skin retaining walls. The retaining wall systems are suitable for commercial and residential applications, small or large.

Extensively Tried and tested

Terraforce stackable, no-mortar retaining wall blocks adhere to local and international standards, having undergone extensive laboratory testing – based on SANS 207, BS 8006 and ASTM-D6916-18 – by professional accreditation agencies over the last four decades.

In addition, licensed manufacturers must adhere to strict minimum specification and regular compressive strength tests as set out by Terraforce Head office, ensuring that the end user is supplied a quality product. Terraforce is a member of the Concrete Manufacturers Association (CMA) and a Level Four BBBEE Contributor.

Commitment to recycling

Most Terraforce Licensed Manufacturers use recycled concrete and clay bricks in the manufacture of Terraforce stackable retaining blocks. Breakage during manufacture is also reused in production.

Our Products

Important note on product selection:

Terraforce licensed munufacturers stock their own selection/sizes of Terraforce precast concrete blocks, this means the full range of products IS NOT sold at every outlet.

Client Testimonials

"Fantastically versatile product that offers structural strength, aesthetic arrangement and provides a plantable living feature wall. Peter was extremely helpful and responsive in his communication and both deliveries arrived on time."

- Natasha Mikula, UK

"Happy to show anyone local what can be achieved with your great product, I love the wall!” This wall is in Rock, Cornwall, and was lovingly planted with 4000 plants."

- Carol Barkwell, Devon, UK

"Glad to see its taking off in the UK. We got ours 10 years ago – first delivery in Dorset and we built our wall. The blocks made our garden look amazing and so easy to install too!"

- Diana Kenney, Wiltshire, UK

"My husband has created an amazing wall with your Terraforce blocks. We live on a slant and we have built a retaining wall and built up from the bottom of the slant to the house level and have created an amazing pool area with views out over the area. The Terraforce wall is a highlight!!! I have attached a couple of before pictures also. We basically have used the Terraforce wall to build up and pop the pool into. Thanks for such an awesome product!!!"

- Simone Elwell, Perth, Australia

"Just last weekend we built some stairs in the wall with the blocks as we love it so much – it looks good (even though the blocks you guys use for stairs are rectangular and these are curved)…we plan to glue the caps for safety…It’s not completely done but nearly there — we now have the pool in and the 1 metre wall is doing well – we LOVE LOVE LOVE Terraforce!!!!"

- Katherine James, Perth, Australia

"Terraforce is a fantastic product. The longevity of the blocks is phenomenal and highly recommended as a solution to all applicable retaining requirements. Been using your product for many many years and very impressed."

- Kevin Bailey, Cape Town, South Africa

"Though I’ve never enjoyed trampolines in a landscape, you’ve done well. Particularly noteworthy is the open stem wall top. Though I’ve terraced with many materials, this is as a concrete block turned on its side: supportive, reinforces water conservation and slows spillage. For someone at the bottom of a hill, water distribution both retention and redistribution is important. Great job!"

- Brenda Miller of Florida

"The rock face blocks blend with the natural environment, their sandstone colour matching the surrounding soil. They are plantable and permeable, allowing the landscapers free reign."

- Hannes Bouwer of Bouwer Architects

"It is a very well known product, and we liked that the system is a design and supply item."

- Karien Visser, engineer with KLS Consulting Engineers

"Terraforce offers a user-friendly landscape remodelling method that is flexible, cost-effective and faster to install than off shutter concrete or bricks. The entire job can be done on site and the blocks fit in just about anywhere."

- Tobie Cilliers from Strata Civils

"I am thrilled with the ease of installation. All that is required is a level piece of ground with a matching diameter.” Packing the versatile blocks on a circle marked out around a central foundation hole is a breeze, although requiring some basic construction skills."

- Rudolf Eksteen of Moorreesburg

"Due to the four loops at each interchange being different the Client requested that each interchange design be unique. The challenge was to be creative, functional (for maintenance), keep aesthetic appeal and to maintain the structural integrity required. This kind of variation could not have been achieved with the precast walls originally proposed. As a result, the walls showcase the remarkable design flexibility that is possible with a Terraforce block, by alternating between a flush, round or rock face finish, varied setbacks for a featuresque appearance, integrated steps and good plant cover."

- Simon Knutton of Knutton Consulting
