Road Drainage Systems with Typar Geotextile

Overview To manage surface and ground water for road network, subsurface drains are built with a permeable conduit such as corrugated plastic, geonet, tubing, tile, stone, pipe or any combination installed beneath the ground surface to collect and/or convey drainage water to an outlet. Effective subsurface drains are essential to prevent the harmful and destructive …

Railway Track

Railways, new tracks and track renewal Railway tracks is areas with soft soils and high ground water levels are susceptible to settlement and requires regular maintenance for track alignment and safe transportation. Typar SF below ballast provides stabilization and separation to reduce impact of dynamic loading. Typar SF avoids ballast contamination by pumping effect due …

Typar vs Other Geotextiles Performance

Typar offers benefits of high tensile strength of woven geotextile as well as elongation of needle punch geotextile making it the most versatile geotextile. Overview DuPont™ Typar® SF has a high tensile strength, a high elongation, and also a high initial modulus which is the ideal combination of properties for geosynthetic applications (for comparison see …

PKHA Bridge Abutment Slope Protection

  A layer of heavy stone, broken rock (rip-rap), gabions or pre-cast blocks is often used to provide permanent erosion protection for Submerged bridge piers and foundations. Erosion protection structures or armor systems dissipate the hydraulic forces that cause erosion, and they preserve the subgrade soil or fill soil behind it. A typar is required between the …
