Retaining Walls

At IC Paving and Walling, we specialize in Terraforce and Geolok retaining wall systems, including the popular Terraforce L13, L22, and Geolok 300/400/500 from Corobrik. These interlocking systems are widely used across South Africa for both residential and commercial retaining wall applications.

Why Choose Terraforce and Geolok Retaining Walls?

Versatility – adaptable for various terrains and landscaping designsPlantability – allows roots and water to penetrate freely for natural greenery
Durability – suitable for light and heavy-duty retaining walls
Customizable – available in multiple colours and textures to match your property

Applications:

-Structural retaining walls
-Landscaping features
-Garden seating and stepping arrangements
-Driveway and property boundary walls

These engineered retaining walls are designed to withstand South Africa’s harsh climate, offering structural integrity and long-lasting stability. Closed vertical and open horizontal surfaces provide superior interlock, resistance to sliding-shear forces, and effective mass gravity support.

Whether for home landscaping or commercial projects, our retaining wall solutions combine strength, aesthetics, and functionality.

1. Closed vertical surface structure provides maximum amount of soil (mass) within the wall and prevents backfill spillage, especially during compaction while at the same time offering uninhibited permeability.

2. Superior bearing capacity is provided by double wall thickness of adjoining elements which also means a broad base for substantial block on block frictional resistance. Flush fitting, horizontal interlock over full width of structure effectively avoids point loads and performs even when forming relatively sharp convex or concave curves. The units are made on static machines, capable of producing a very dense concrete product of uniform shape and strength. This also facilitates accurate horizontal alignment.

3. Vertical Interlock in the form of close fitting concrete keys provides postive shear resistance at all wall inclinations. Continuous soil core and root systems within the elements provide extra strength. Where further strength is required the designer may resort to reinforcing the backfill with geofabrics or partially / fully filling the elements with reinforced concrete. Double rows present another possibility.
