Swelling may be created in clay soils due to alterations in its moisture content – a swelling that causes damage to nearby engineering structures (roads, routes and the like).
Lining with H.D.P.E Geomembranes enables the clay to maintain constant moisture content and thus prevent its swelling.
After processing the clay to the desired moisture, H.D.P.E Geomembranes are deployed atop the horizontal subsoil as well as in vertical barrier ditches. The lining on the horizontal plane will prevent the penetration of water flowing vertically from the ground’s surface or penetrating through the asphalt layers. Vertical barrier ditches are being dug to a depth of 2.5 m thus preventing moisture content alterations due to water flow within the soil as well as preventing water penetration from drainage channels and infrastructure systems.
Clay lining will prevent the formation of damages (cracks, differential sinking and the like) instigated by the cyclic swelling of clay on the pavement’s surface, lengthen the road’s repair and upkeep period and improve its quality.
