Retaining wall with element of green

Retaining wall with element of green

Using TenCate geosynthetics, a retaining wall has been erected in the project to widen the railway line between Hamilton and Toronto (Canada). A new robust slope has been constructed using TenCate Miragrid®. Application of this material included an element of green: the full restoration of the habitat of Sunfish Pond, an adjacent pond with rare types of fish.

TenCate Miragrid® is covered with sand

The existing railway on the 16-metre-high railway embankment lacked sufficient room for expansion, but widening threatened to disturb the natural habitat and the fish stock of Sunfish Pond. The solution: the combination of geosynthetics and a sheet pile wall 5 metres high and 180 metres long. On top of this wall, a slope reinforced with TenCate Miragrid® was constructed against the existing slope.

Before the construction the vegetation on the existing slope had to go. A blessing in disguise: it enabled the Botanical Gardens to replace non-indigenous plants with native plant species. In this way the natural habitat in this area has been restored and improved.



The retained slope is ready for a third railway track to be installed

Furthermore, the project demonstrates to the parties concerned how, thanks to TenCate Geosynthetics, ‘green engineering’ can produce positive economic results.
