Landfills

StrataWeb® is an excellent system for confining the soil cover and protecting the membrane below without the need to puncture it. It can be used for steep slope capping allowing for better utilisation of available land. For large mining overburden dumps and tailing dams, StrataWeb® can be used to protect the slopes utilizing mining waste or debris.

Most leachate system failures are not immediate. They develop over time due to clogging of drainage media, differential settlement of the waste mass, increasing waste loads, and changes in leachate chemistry as decomposition progresses. These long-term mechanisms can compromise drainage efficiency, alter flow paths, and increase hydraulic head on the liner.

Vertical landfill expansion is not a volume grab. It is a risk-managed, engineered solution that relies on reinforced soil systems to control stability, protect containment, and ensure performance as loads increase over time. Constrained site and space availability has over the years put pressure on getting more out of the airspace above landfills. Here, Strata Geosystems implemented the concept of vertical expansion through safe management of the existing site and cells.
