The use of geotextiles in urban planning simplifies construction processes, making more use of available soils and materials and even construction and demolition waste.

In this blog we will see a case of work in which the use of geotextiles in urban planning, specifically woven geotextiles and geogrids, eliminated conventional lateral confinement elements such as retaining walls, confinement beams and curbs or piles, avoiding the use of materials such as concrete, steel and complementary activities.

GENERALITIES:

It involved the construction of an area for cycle parking using an articulated pavement, adapting the existing land up to the foundation level where a layer of woven geotextile was placed. FORTEX for separation and stabilization of subgrade soil. This example of the use of geotextiles in urban planning shows how available resources can be optimized. For the perimeter confinement of the area, GEOBRICK structural geocontainers filled with soil from the excavation were used. In some sectors, fragments of brick and common material were used for filling, which were finally arranged and compacted adequately to achieve the required stability. A biaxial geogrid was used over the entire area. GEOESTERA 50 to increase load capacity and reduce possible surface deformations. The end of the geogrid was used to form a curb on paving stones confined with the mesh. Finally, a 5 cm layer of sand was placed and on top of this a rolling clay pavers, as illustrated in the following detail.

Used materials:

GEOTEXTILE FORTEX BX 30:

  • The woven geotextile initially allowed a separation of the site material from the shaping material. Additionally, its inclusion in the structure reinforced and mitigated the migration of fines through the GEOBRICK joints.
  • woven geotextile FORTEX BX 30, due to its resistance, stabilized the subgrade, mitigating possible differential settlements and guaranteeing a homogeneous distribution of the loads to the subgrade. This aspect is crucial in the use of geotextiles in urban planning.
  • The contribution of the geotextile (confinement and reinforcement) allowed the fillings used to be materials from brick waste, thus optimizing the use of geotextiles in urban planning for a more sustainable construction.

GEOBRICK STRUCTURAL GEOCONTAINER:

  • It allowed the use of material from the site to achieve a perimeter confinement structure, containing the fill and allowing rapid progress in the formation of the platform. This is another example of the efficient use of geotextiles in urban planning.

HYDROMEGREEN GEOMETRIC GEOESTERA 50:

  • It was used to confine the fills and the final paver structure, thus avoiding the use of conventional alternatives such as concrete beams and piles. This case demonstrates how the use of geotextiles in urban planning can replace traditional methods, offering more sustainable and economical solutions.
