Geogrid
Geogrid
Petroseal supplies polymer geogrid for soil reinforcement—interlocking with fill particles to increase bearing capacity and control deformation under heavy embankments. On dam and hydropower projects, geogrid is laid in lifts with structural fill on approach roads, platform edges, and reinforced earth structures adjacent to geomembrane-lined zones. Designs for Diamer Bhasha Dam (FWO–Power China joint venture) and Suki Kinari Hydropower often combine geogrid, geotextile separation, and HDPE geomembrane in staged construction sequences.
Key features
- — High tensile ribs for soil reinforcement and basal stability
- — Biaxial and uniaxial grades for different load directions
- — Used under dam access roads and reinforced fill zones
- — Pairs with geotextile and geocell in composite designs
- — Nationwide supply for WAPDA-scale civil contractors
Applications
- — Dam approach embankments and platform reinforcement
- — Reinforced earth retaining structures
- — Heavy haul road bases near hydropower sites
- — Working platforms over soft ground with geotextile separator
