Lagoon and waste capping
Industrial waste sites and sludge lagoons have been problematic for engineers and owners for a long time. They must be made safe, as well as complying with the prevailing environmental regulations. The capping of such sites not only makes site access difficult, but requiring environmentally sound, long-term solutions which won’t exceed the inevitable cost restraints. This is where Tensar Technology can help, by making use of our many years of experience to create innovative solutions.
Tensar’s extensive expertise in ground stabilisation has proved invaluable in refining techniques using geogrids for the safe and secure capping of sludge lagoons and other industrial waste.
- Grids have been used over extremely weak ground and may be the only practical means of initial site access
- Tensar geogrids and geocomposites can assist in the safe placement and compaction of the fill
- This provides a mechanically stabilised layer and increases bearing capacity – enough to make some previously unusable sites usable
Reinforcement and support to landfill liner systems
Modern engineered landfills require reliable lining systems, both below to contain leachates and gases and above as part of the capping system to contain gases and exclude rain and snow water infiltration. Their low permeability barriers, whether engineered clay, geomembranes or composites of the two, will not function effectively if subjected to elongation. Tensar uniaxial geogrids are used as reinforcement within such lining systems to limit tensile strain.
