2002 Waste Disposal Area
Capping project for a waste disposal area in Kfar Saba, located near Highway 6 (the Trans-Israel Highway). The site had previously absorbed domestic waste. The height of the waste is 25m with a slope of 1:2 (vertical: horizontal). As part of the construction of the Trans-Israel Highway, it was decided to close the site and to perform general landscape restoration that included: - Work to arrange gradients and slopes.
- A system for releasing biogas. The system includes inkdrain type drainage mats, a perforated HDPE pipeline for collection of gas, and burning the gas using a flair.
- Lining with textured HDPE mats 1.5mm thick.
- Drainage system for upper surface runoff that includes drainage mats and a pipeline.
- Spreading geogrids with a strength of 25 ton/ linear meter to reinforce the embankments.
- System for preventing erosion that includes a non-woven geotechnical mat and planting perennial flora without irrigation.

2003 El-Canada Pond
he pond is used to run the water system at a hydraulic power station in the rainforests of Guatemala. There is volcanic activity in the region, so there is a need for evacuation of gas that accumulates beneath the lining sheets. The site is located in a section of rocky soil (basaltic rock), and there is therefore a need for mechanical protection of the lining sheets against puncturing. Advanced engineering calculation characterized the integrated use of a mat comprised of a woven mat inside a non-woven mat. This is in order to protect the HDPE lining mats. Products installed in the project: - Woven mat, combined with a non-woven mat with a weight of 1000g/2m for mechanical protection.
- Drainage mats (Gonet) to conduct gases that escape from the ground.
- Lining with textured HDPE mats 1.5mm thick.

2003 Acceleration of Consolidation, Kishon Road- Haifa
The Kishon Road project at the Haifa port is located on top of clay-containing, soft, saturated soil that is compressed normally. Soil of this type is characterized by consolidation over the course of many years that causes differential settling and damage to engineered buildings. The Kishon Road project contains freeways as well as high embankments. The settling expected as a result of consolidation is c. 1.5m over the course of 10 years. In order to accelerate consolidation, Admir installed vertical drains reaching down to 25m. The distance planning and the depth of the drains enabled the attainment of 90% of the expected settlement in the first year. Completing the consolidation process enabled immediate use of the embankments. A downloadable PDF is attached for further information.

2004 Highway 5 Yarkon – Kesem
Highway 5 is a major east-west artery. This highway has suffered cracking due to oxidation, fatigue, and other reasons. During a project to widen the highway, it was decided to treat the existing asphalt by installing a mat to retard reflective cracking. Mats between layers of asphalt were spread over the existing pavement, after scrubbing. Above the mat, a new, 5cm thick upper layer of asphalt was laid. The spreading of the mat was designed to retard reflective cracking from the old layer of asphalt to the newly laid layer. A downloadable PDF is attached for further information.

2004 Arrangement of Maharal Creek
The Maharal Creek is located near the Tzerufa community and crosses Highway 2 (the Haifa- Tel Aviv Highway). The creek is characterized by a high output of water during a relatively short rainy season. Neoweb (manufactured by P.R.S.)- type beehive pattern, 10cm high and filled with concrete, was spread over the riverbanks to prevent damage from erosion and water flow. Installation of the Neoweb beehive pattern included pockets for releasing hydrostatic water pressure while incorporating flora to improve the landscape.

2005 Yannai Interchange – Reinforced “Green” Embankment
In the framework of the expansion of the Yannai Interchange of Highway 2 (the Haifa- Tel Aviv Highway), a 10m high embankment that includes a gradient with a 70 degree slope. The base of the embankment is below the water table. Planning requirements included fast restoration of flora on the gradient, since the project is located inside a nature reserve. The chosen alternative included reinforcement of the embankment by Portrek 80/30-20 -type geogrids with a tensile strength of 8 tons/ linear meter. Their purpose was to ensure the general stability of the embankment. Additionally, a green façade of green terramesh, combining a stable façade element with vegetation, was installed on the façade of the gradient.
