Every day, we face problems related to hydrogeologic collapse, such as erosion and landslides. These problems originate from man’s need to develop urban areas, transportation routes, and the need to use soil and land for farming, whilst also trying to maintain the delicate balance of the surrounding habitat. The construction of new roads will always […]

Soil erosion is a major environmental issue affecting the mostly semi-arid and dry African continent. Second only to Asia, Africa ranks high on the list of continents most affected by soil erosion. Basically, soil erosion occurs when the fertile layer of topsoil wears away from the land’s surface, due to attrition by: Natural forces such

A Gabion is a somewhat strange word for extremely strong wire baskets that are filled with stones and used mainly to stabilise and prevent erosion on slopes, road embankments and riverbanks. The word Gabion comes from the Italian word “gabbione” which means “big cage.” Gabions are used to: Stabilise slopes Help prevent soil erosion Mitigate

Gabions arrive at your job site in flat packs and are easy to assemble – no special skills are needed. This is a basic, step-by-step picture guide to assembling gabions on site. If you would like to see our video on YouTube, please go here If you would like to see a more detailed and

Basically, gabions are strong wire baskets that are filled with rocks and installed to strengthen slopes. Gabions are used by contractors and engineers, especially in countries like Ethiopia and across Africa, where soil erosion and landscape stability are significant concerns. Gabion structures or walls are known to last over 100 years. It’s hard to believe

Gabion baskets and Gabion Mattresses are transported to your job site in folded “flat packs”. This makes the most sense, as it makes them more economical to transport. You will need to assemble and install the Gabions at your site. This article explains, in technical detail, how to install Gabions successfully. This technical guide is

This is the second in a series of articles about bio-engineering techniques. In the first article, we discussed various bio-engineering techniques for soil erosion, but how do you know which solution is the best one for your project? Today, we take into account: The “Minimum Energy Level” Concept Lining systems for slope protection Wall systems

This article is for anyone who is concerned and interested in the protection and mitigation of ecosystems, especially engineers, landscape architects, biologists and soil conservationists. It illustrates the compatibility of incorporating environmentally sound concepts into the design of engineering solutions. Important: It must be stressed from the onset that any soil bioengineered technique adopted, must:

In Africa, our environment has undergone significant changes due to continuous human development. Let’s discuss how we can protect slopes and reduce soil erosion, in the process protecting precious layers of top soil. Major problems related to soil conservation and slope protection are: Erosion Filtration Landslides Rockfalls Unstable slopes / embankments In this article, we

Gabions are utilised as a major component of retaining walls in all kinds of applications.   Their relatively low cost, flexibility and free draining properties have long been known; over the years as engineers have become more conscious of environmental needs, the natural appearance of gabion walls has come to be appreciated as an additional
