FEATURED PROJECTS
Upgrades to Kassier Road Phase 1A and 1B
Client:
Stefanutti Stocks, SMEC, ETA
Location:
Assagay / Hillcrest – Outer West Durban
Project Scope:
Upgrades to Kassier Road Phase 1A and 1B, Durban (2024–2025). The development of eThekwini’s outer west region included the construction of a mixed-use economic precinct, beginning with the flagship Westown Square and followed by traffic infrastructure upgrades along Kassier Road.
The 3 km road upgrade, starting from Hillcrest Private Hospital, required the construction of a mechanically stabilised earth (MSE) wall to support the widening of the road from a single to a dual carriageway. The MSE wall was built using a composite structure consisting of a main wall with the TerraClass system and a return wall with the TerraTrel system, incorporating steel reinforcement inclusions.
The wall reaches a maximum height of 8 m and extends 165 m in length, enabling Kassier Road to accommodate outbound traffic access to the M13 Durban-bound route.
11th Avenue and Dinkleman Interchange
Client:
Afriscan Construction – Nankhoo Consulting Engineers, ETA
Location:
Clermont / New Germany – Durban
Project Scope:
Upgrades to 11th Avenue and Dinkleman Interchange, Durban (2024–2026). OBECA (Pty) Ltd was appointed as a specialist subcontractor for the construction of six mechanically stabilised earth walls (MSEWs) of varying lengths and heights. These retaining structures supported the construction of engineered fills that carry inbound and outbound traffic for the interchange, connecting Clermont and New Germany with Dinkleman (MR 577) via Corridor 3 of the Integrated Rapid Public Transport Network (IRPTN).
The six MSE walls comprised 4,000 square metres of concrete panels, over 100,000 linear metres of reinforcement inclusions, and 30,000 cubic metres of structural fill.

Flood Repairs to Main Road P398 – M4 Highway
Client:
ThelBridge Enterprise, Naudi Consulting
Location:
Westbrook, Ballito – Durban
Project Scope:
Flood Repairs to Main Road P398 – M4 Highway, North Durban, KZN (2023).
Following the severe floods that struck the eThekwini Metro in April 2022, the road section between Westbrook Beach and the Tongaat River Bridge suffered a major embankment collapse, leading to the closure of this section of the M4 Highway until its reopening in 2023.
OBECA was appointed as the specialist subcontractor responsible for executing the embankment repair works. The reconstruction involved bulk earthworks to remove unsuitable in-situ material, establishing a 2.5 m pioneer layer foundation, constructing a 13 m-high mechanically stabilised earth wall spanning 60 m, and reinstating the compromised roadway.
The project faced numerous challenges, including limited access and restricted working areas, adverse weather conditions, and the collapsible nature of the in-situ Berea Red soil. Due to tight time constraints, a second work shift was introduced to ensure timely completion. On 14 December 2023, the road was successfully reopened to the public, reconnecting eThekwini with the iLembe District via the M4 Highway.
Booysendal Mine Buttress Wall, Mpumulanga
Client:
Grinaker LTA, Northam Platinum
Location:
Booysendal Mine – Mpumalanga / Limpopo
Project Scope:
Booysendal Mine Buttress Wall (2023). To increase the long-term capacity of a Tailings Storage Facility, a conventional backfill solution would have required relocating the pump station positioned at the toe of the dam embankment. To avoid this, a 12 m-high by 50 m-long mechanically stabilised earth wall (MSEW) was constructed to retain and stabilise the fill in the affected area.
The structure was built using the Terramesh system in conjunction with geocomposite reinforcement and blended engineered fill.

Oceans Mall, Durban
Client:
WK Construction
Location:
Umhlanga – Durban
Project Scope:
Oceans Mall, Durban (2022). The construction of the Oceans Mall and residential towers required a composite retaining system to stabilise Flamingo Lane as it joined Ridge Road, creating an access route for delivery vehicles into the mall’s loading zones.
The structure comprised a lateral support system combined with a mechanically stabilised earth wall, which reached a maximum height of 12 m and extended 150 m in length.
A number of challenges were successfully managed during the project, including traffic management and the logistics of hauling in over 15,000 cubic metres of backfill within a restricted working area.
