Soil encapsulation

The use of our geomembranes in soil encapsulation ensures the sustainability and long service life of the infrastructure.

The encapsulation of unsuitable or marginal soils is a process present in the construction of some linear works such as roads and railways, especially when there are technical or environmental limitations for the use of borrow materials near the location of the layout. The main objective of this process is to treat and confine marginal soils, which may include those with low bearing capacity, high expansivity, susceptibility to erosion, or drainage problems. These factors can compromise the stability and durability of roads and railways.

Geomembranes play a crucial role in encapsulating marginal soils in these infrastructures. These impermeable sheets are used to cover and contain soils, creating an effective barrier that prevents soils from reacting with water. Geomembranes also help prevent erosion and displacement of the encapsulated soils, ensuring the long-term integrity of the structures they support.

Atarfil geomembranes, thanks to their mechanical properties, strength and durability, are ideal for this task. The use of our geomembranes in soil encapsulation ensures the sustainability and long life of the infrastructure, minimizing the risks associated with the use of unsuitable soils.
