Project follow-up: Terraforce Retaining Walls® walls at eZulwini, Eswatini, eleven years on
Cutting into the hillside for the new International Convention Centre and five-star resort exposed steep, unstable slopes. The solution was a tiered Terraforce® wall system: a 2m double-skin first tier, the base for 4m stepped tiers, reaching up to 26m, an all-time high for Terraforce® retaining wall engineering to date.
Designed by Fred Laker for Terrasafe® and installed by EFS Construction, a Terraforce® licensed manufacturer and recommended contractor, the walls used 267,700 customised L11 blocks.
Seedling bags were built into the infill as each tier went up, and the red oxide blocks now sit under groundcover, shrubs and creepers, as photographed in September 2026.
Selected Terraforce® products are manufactured under license by Corobrik, KwaZulu Natal:
