Maccaferri’s MacRes system was chosen for the development of a MSE Wall on the Mount Edgecombe Interchange, north of Durban

In addition to MacRes, other retaining wall and soil reinforcement solutions were used in the works, requested by SANRAL

Maccaferri products, including MacRes, were used at the Mount Edgecombe Interchange. The area required the construction of a 10,300-square-metre Mechanically Stabilized Earth Wall – retaining wall – which was designed by using Maccaferri’s Macstars Software.

Due to the increasing development in and around the Umhlanga and La Lucia Ridge areas, north of Durban, motorists have been experiencing severe delays for quite some time. The Mount Edgecombe Interchange, managed by the South African National Roads Agency (SANRAL) therefore required a system offering free-flow traffic movement to accommodate the growing capacity, particularly during peak hours.

With the involvement of civil engineering consultant SMEC South Africa, Maccaferri Africa was appointed to design the Mechanically Stabilized Earth Walls for the project, which was developed by using the MacSTARS Software, while Maccaferri’s MacRes was the chosen product.

This system is ideal for the construction of walls where high loads, durability and robustness is a requirement as on the Mount Edgecombe Interchange. MacRES consists of precast concrete panel facing elements in combination with ParaWeb soil reinforcement geostrips.

Between the two contractors on the project, Italy’s CMC Group and Brakpan-based Stefcor Construction, nine MSE Walls were constructed, with an approximate total square area of 10,300 metres. Ultimately, SANRAL opted to have both patterned and smooth finished walls with concrete panels.

Maccaferri Africa, together with MSJ Geotechnical Services, are currently Project Managing the MSE Wall installation to ensure that the construction process is completed in accordance to the project specifications, and to provide technical assistance where and when required.
