Soil reinforcement is a way to increase the strength and stiffness of soil.
In old ways, it used to reduce soil erosion at marshy land and river boundary sand.
It is done by placing a bio-fabric i.e, bamboo, in the pattern of the network in soil with a mixture of aggregate-sand to make it stiff and compacted mass.
These bio-fabric acts as a reinforcement and resist tensile stresses, which ultimately reduce erosion.
But, This technique does not give satisfactory results as compared to modern retaining Structures made of concrete.
