Soil erosion is a natural process defined as the wearing away of the top layer of soil where the soil particles making up the topsoil are worn away due to water. The main factors that influence erosion are rainwater, wind and the concentration and the downflow of water on slopes. Even though this is a process which is mostly natural, it is often aggravated by man-made structures: this phenomenon can significantly affect structures themselves and human activities.

The erosive process can be mitigated and mostly avoided by protecting and preserving the fragile soil layer and creating a suitable support to vegetation.

To protect soil from washout, that doesn’t allow vegetation to grow, we can use technical materials as bionets, biomats, geomats and erosion control geocomposites.

Bionets are made of natural coir fibers, jute or sisal, woven or knotted so as to form an open structure and at the same time able to adapt to the substrate. They are 100% biodegradable and eco-friendly.

Biomats are made of layers of biodegradable randomly assembled natural fibers: they form a half-open “chaotic” structure that easily adapts to the ground on which it is installed.

Biomats are made of straw, coir, straw and coir, jute or other biodegradable fibers that are compatible with the environment. Biomats can be also pre-seeded with different seed mixtures depending on the situation.

Bionets and Biomats are characterized by an high water holding capacity and they can protect the soil against surface erosion phenomena through a mechanical protection; they foster the formation of an ideal microclimate and, thanks to their decomposition over time, they increase soil fertility.

The anti-erosion geocomposites are formed by different combinations of bionets and biomats or by combinations of these with plastic geogrids or metallic reinforcing grids.
