In 2019, Edgewood Middle School underwent renovations and expansion, including the construction of a new parking lot. To utilize the available property, a wall was needed to create a level surface area for the parking lot.
PROPEX® Pyrawall®, an engineered wrap-face vegetated solution for constructing reinforced-soil walls and steepened slopes, was selected to reach the desired grade. Initially a modular block wall was considered, but PROPEX Pyrawall was selected because it was a more cost effective and environmentally friendly solution.
Eight, one foot, PROPEX Pyrawall lifts were constructed to raise the grade for the new parking lot. The wall was fully vegetated within four months of construction, and now blends with the current landscape.

Geogrid-reinforced embankment for GO Transit rail service expansion
GO Transit expanded rail service between Hamilton and Toronto, requiring a third track on a historic embankment near Sunfish Pond. A geogrid-reinforced slope with a steel sheet pile wall was implemented to meet structural and environmental requirements.
MSE walls with MIRAGRID XT for rail expansion
GO Transit used hybrid MSE walls with MIRAGRID XT geogrids to stabilize embankments on Lakeshore West Line, ensuring stability under space and load constraints.
MIRAFI geotextiles prevent subgrade failure and reduce track downtime
Canadian Pacific Railway (CP) identified track settlement issues and partnered with Solmax and Clifton Associates to implement a geosynthetic solution, reducing ballast use by 43% and completing repairs on a 72 ft section in under seven hours.
