The floods that occurred during April 2022 in KZN and the subsequent damages have proven that no bank is stable unless properly protected with a correctly installed Gabion. Between 13th April – 30 April 2022, a team from Gabion Baskets visited approximately 50 different sites and still counting, subsequent to the most recent flooding again in May, where, due to poor retaining or no retaining at all, extensive damages occurred as well as loss of life.
Most sites visited were either retained by concrete retaining blocks or no retaining at all, it has also become evident that due to poor storm water draining, underground erosion occurred because of burst storm water pipes and sewage drainage, which caused banks to collapse. This, coupled with the topsoil erosion which caused severe mud slides spelt danger, the most common failures were due to sliding because of poor foundations and insufficient weepholes.
Below are some of the sites visited and a brief description and suggested methods provided.
