Protecting soil from erosion from water and wind can sometimes be accomplished with plain vegetation. If vegetation is absent after construction works, or is difficult to establish on steep slopes where loading may be too high for plain vegetation to withstand Enkamat offers the solution.
Enkamat is an open three dimensional synthetic mat consisting of randomly placed filaments of polyamide/ nylon.
Enamat is made of an inert material which makes it very durable and able to withstand long periods of time. Natural vegetation reinforcement materials such as jute,c, flax, wood wool or straw-mats only last a short period of time. They are only meant to provide temporary protection up to the point that the vegetation can take over this task. Enkamat not only offers support in the early stages of the vegetation growth but adds extra strength after the vegetation is fully grown. Natural materials are not consistent regarding their quality. Enkamat is manufactured under controlled conditions. This ensures a high quality of the material according to ISO 9001 standards.
Enkamat fills the gap between a protection with a plain vegetation and a more radical protection with materials such as rock, concrete or asphaltic mixtures.
The advantage is:
Enkamat vegetation cover provides protection to the subsoil against erosion in several ways:
With Enkamat the vegetation roots bind around the filaments thru forming a dense and continuous system of filaments, soil and roots as shown in the image above. This implies that
The following applications have been identified
Newly constructed slopes, for example road and railway embankments, on which the vegetation is poor or absent can be subject to severe erosion by rainfall and wind. Soil particles on the bare embankment are transported by run-off or wind, gradually resulting into deep gullies and deformations. Enkamat can give initial protection against this type of erosion, k the futile soil and seeds in place and supports the growth of vegetation.
Enkamat can be seeded with a suitable seed mixture and filled with humus or topsoil. On very steep and long slopes the mats can be filled and seeded hydraulically. The development of a proper vegetative covering normally takes several months.
It is important that Enkamat is placed on a smooth base, particularly when eroded embankments have to be covered. The surface has to be leveled and the holes filled and compacted to give a regular surface. When rainfall is very extensive it is necessary to provide extra drainage provisions such as discharge channels. On very long slopes it is recommend to construct small bank of the slopes in combination with drainage order to reduce run-off velocities.
