OVERVIEW
Holding it all up, making sure nothing gives up or gives in.
Strata provides solutions to the waste containment industry for vertical landfill expansion projects, and more; and economical solutions to secure land operations.
Landfill capping
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.
Leachate management
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
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.

More success stories
StrataWeb® geocells – A slope erosion protection system for embankments
The Jordan Ministry of Energy and Mineral Resources (MEMR) was planning to build a petroleum strategic reserves terminal in the east of Amman, Jordan. They wanted to increase the petroleum storage capacity in the area, which required an increase in the base width of the embankment. The slopes of the embankment required protection from slope erosion.
Slope protection of partial wall on flyover using StrataWeb® geocells
The ramps of the grade separators are constructed either as embankments with natural slopes or as reinforced soil walls. In the case of partial walls, where sloped embankments are supported on reinforced soil walls, the embankment slopes needed to be given adequate protection against soil erosion, which could otherwise damage the fascia of the underlying reinforced soil wall and also induce seepage into the system. The slopes of the embankments were of the order of 30° with the horizontal. The reinforced soil walls supporting the embankments were as high as 10 m. The heights of the embankments were of the order of 5 m.
Rehabilitation of road in the busy city town centre in Karnataka
Monsoons in North Karnataka are notorious for damage to roads. The site was plagued with problems like reflective cracks, potholes, undulating surfaces etc., resulting in slow traffic movement and heavy vehicular damage. This stretch had to be rehabilitated time and again over the past several years, and no solution was proving to be long-term. Since the area is a major commercial hub, it was impossible to close off this section for an extended period completely, so a quick but long-term solution was needed.
