Surface water shapes the soil, now more than ever before, due to the increase in extreme events. Today, there is a growing awareness that the ‘natural’ resources we have at our disposal are capable of limiting the effects of scouring and runoff. On dry slopes, for example, soil erosion is the process whereby materials are removed by the mechanical and chemical actions of wind and water. From a technical/scientific perspective, a further distinction is made: in addition to the concept of soil erosion , there is soil loss and sediment yield .

The effect of weathering on the soil is therefore a phenomenon to be foreseen and controlled. On the surface, the causes cannot always be detected, but a Geologist – after carrying out the necessary research – will pinpoint the problems and recommend solutions.

The main phenomena associated with soil depletion are:

• the thickness of arable soil, which includes organic substances, water, mineral salts and fine particles, decreases on a local scale: within a few generations, fertile soil can become arid;
• accelerated and uncontrolled surface erosion can cause landslides on steep slopes, increasing the extent and intensity of crumbling to the point of destroying the vegetation cover of an entire slope;
• eroded material is carried downhill, thereby reducing the capacity of watercourses and thus increasing the risk of flooding;
• the sedimentation of eroded material that ends up in irrigation channels decreases their efficiency and service life;
• eroded material, often laden with chemicals from agricultural practices such as fertilisers and insecticides, instead of being absorbed by the soil, becomes concentrated in watercourses, spreading pollution over a wider area.

The new design concept – determined by precise environmental choices – undoubtedly promotes sustainability. In this respect, on dry slopes, soil ‘helped’ by suitable products to encourage revegetation becomes a very strong ‘barrier’ to inclement weather over time.

By observing the grassed embankments bordering major road and railway routes, we can appreciate the need, which is met, to protect the safety of infrastructures against problems of topsoil slippage. These are artificial embankments, created to meet technical requirements. They were therefore barren at the time of construction, and hence exposed to the impact and removal of soil by rainwater. Ensuring grassing therefore increases the level of safety, improves visual impact and, last but not least, respects biological diversity that is preserved.

New TeMa Geo Solutions materials make these solutions possible. To encourage vegetation to take root, TeMa has come up with K-Mat synthetic geomats and biomats in natural fibre matting (straw, coconut and jute), ECOVERMAT and ECOVERNET, in addition to the X-Grid PET-C AMrange of geomats, which are also useful for reinforcing slopes.

TeMa, an Italian company established in 1993, has gained experience on 4 continents with products for the world of geotechnics, which are trusted by planners and contractors. Over 30 years of providing geotechnical solutions that aid the soil with its own erosion control and stabilisation potential, resulting in a clear environmental advantage.

The Katlehong job, in South Africa, was a major project for TeMa in a highly critical construction context, given that it involved building a municipal water reservoir in the shape of a 200 thousand hectolitre tank.

With the introduction of a number of geosynthetic products in place of conventional building materials, the costs came in significantly lower than initially projected and structural efficiency was improved considerably across such a large project, promising to deliver a long service life.

The TeMa solution in cases like these: laying X-Grid PET-C-0 100/100 Biax — a biaxial stabilization geogrid woven from high-strength polyester, with a protective polymer coating — over the whole bed in alternating layers with fill material between. With each new layer, the geogrid has to be placed with the appropriate orientation to ensure the structure’s foundation will provide the required overall stability and bearing capacity, thus allowing for and negating the negative effects of any differential settlement.

The use of TeMa Geo geogrids allows for space to be incorporated into the design to accommodate the underground services associated with the structure being built, while providing the designer with significant advantages, compared to the use of conventional natural materials, including ease of installation and shorter construction timeframes.
