WITHOUT ALYAF  

Terrains across the Middle East are exposed to extremely hot and arid climates that result in greater evaporation than precipitation. Evaporation draws saline water to the surface from the water table in a continually rising process generally referred to as "Capillary Suction". At the surface the water evaporates leaving behind the salt content.

The presence of saline contents in these soils hampers healthy vegetative growth. One of the most cost effective and proven methods of controlling the capillary rise of saline water is by introducing a capillary break between the subgrade and the topsoil. The capillary break consists of a coarse granular layer and a layer of ALYAF geotextile.
