The Light House Project: Enhancing Stability and Sustainability with Ocean HDPE Perforated Geocell
Introduction
Ocean Non Wovens supplied 9985 Sqm of Ocean HDPE Perforated Geocell for the Light House Project in Agartala, Tripura. The geocell was used to stabilise soil and control erosion across several areas of the site.
Agartala’s Light House Project is one of six model housing projects built under the Global Housing Technology Challenge of the Pradhan Mantri Awas Yojana (Urban), each demonstrating a different construction technology. Tripura gets heavy monsoon rain, so exposed earth on a large building site washes out easily and soft ground loses strength when wet.
How a perforated geocell works
Ocean HDPE Perforated Geocell is a three-dimensional honeycomb of welded high-density polyethylene (HDPE) strips. It ships collapsed, is stretched open on site, pinned in place and filled with soil, sand, gravel or concrete. The cell walls confine the infill so it cannot spread sideways under load or wash away in runoff.
The perforations in the cell walls let water drain between cells, which keeps pore pressure down in wet ground, and they give the infill extra grip on the walls.
Advantages of Ocean HDPE Perforated Geocell
- Higher bearing capacity: confinement spreads wheel and foot loads over a wider area of subgrade, which reduces rutting and settlement on soft ground.
- Soil retention on slopes: confined infill stays in place on slopes where loose soil would erode, and the cells can be planted.
- Recyclable material: HDPE is a recyclable thermoplastic.
- Easy installation: sections are light, ship flat and are expanded and filled with ordinary site equipment.
- Durability: HDPE resists most soil chemicals, and UV-stabilised grades tolerate exposure during construction and on planted slopes.
Frequently asked questions
How does Ocean HDPE Perforated Geocell prevent soil erosion?
Each cell confines its infill, so rain and surface runoff cannot carry soil downslope as a sheet. The cell walls break up flow paths, and vegetated or gravel infill stays in place on slopes.
Can Ocean HDPE Perforated Geocell be used in landfill construction?
Yes. On landfills, geocells are typically used to hold cover soil on cap side slopes and to build stable haul roads over soft ground. They are not a substitute for the liner system.
Is Ocean HDPE Perforated Geocell cost-effective?
Often, because the confined infill can be local soil or lower-grade aggregate, and the sections ship flat and expand on site. Whether it beats a conventional option depends on the design load, infill availability and site access.
