Geotextile
Geotextile
Petroseal supplies woven and non-woven geotextiles for filtration, separation, reinforcement, and geomembrane protection. Non-woven polyester or polypropylene grades cushion HDPE liners and filter drainage blankets; woven grades support reinforcement and load distribution. On Suki Kinari Hydropower Project and Diamer Bhasha Dam civil packages, geotextile is specified under and over liner zones, behind riprap, and in drainage blankets coordinated with FWO, Power China, and local installation crews.
Key features
- — Woven and non-woven grades for reinforcement vs filtration/separation
- — Cushion layer under/over HDPE geomembrane on dam works
- — Separation and filtration in lined canals and reservoirs
- — High puncture resistance when specified as heavy-weight grade
- — Integrated supply with geocell and geogrid on Bhasha & Suki Kinari
Applications
- — Geomembrane protection and subgrade separation
- — Dam toe drainage and filter blankets
- — Canal bed and slope lining underlay
- — Riprap and rockfill interface on hydraulic structures
- — Road and embankment separation (woven grades)
