Geosynthetics are used extensively in critical structural drainage applications such as basements, bridge abutments and retaining walls, replacing porous concrete blocks, no-fines concrete and other conventional materials. Typical applications include: Subsurface Drains Retaining Wall Permeable Paving French Drains Porous surface layers Drainage Composites The primary design requirement of a filtration layer for civil engineering applications is the development of a graded filter layer in the subgrade soil to maintain separation and eliminate the risk of soil mixing or pumping'. Geotextiles promote development of such filter layers because its uniquely bonded fibers create a pathway that resembles a well-graded aggregate filter. TYPAR Geotextiles provide an effective filter structure since it has both higher permeability rates than adjacent construction soils and the ability to retain fine soil particles, minimizing the piping of subgrade soils. The process of manufacturing fabrics heats the continuous PP fibers and bonds the strands together under pressure to create the geotextile fabric. Bonded fabrics have predictable water flow rates under compaction, eliminating any irregularity of performance when compaction in the field. Geotextiles will provide the same flow rates in the lab or on the job site, eliminating future clogging and costly project damage. Design Considerations Soil conditions Hydrology Hydrogeology Load conditions Drainage and filtration layers are used in civil applications to remove moisture or fine particles from the system. Geosynthetics provide a widely accepted, effective and economic alternative to traditional aggregate & sand filtration layers. Geosynthetic materials are manufactured using a heat-bonded process to create consistent filtration characteristics utilized in a variety of markets, be it industrial filters, geocomposites, or underground drainage layers.
