Monarch Dunes is a resort community that offers residents golf, recreation, and a community vineyard. During construction, a drainage channel was installed in the vineyard to convey surface runoff from the housing development to detention storage basins. Due to the steepness of the slope, the amount of flow, and the erodible sandy soils, the channel severely eroded and failed. The developer needed a solution to provide long-term stabilization of the channel.
Initially hard armoring solutions were considered, but the developer wanted a more natural aesthetic. A combination of PROPEX Armormax® and PROPEX Pyramattress, an engineered mattress system that uses PROPEX Pyramat® 75 HPTRM to construct a geosynthetic/soil/rock composite for protection of channels, slopes, and spillways, was selected. The combined system was designed to provide erosion control on the side slopes and scour resistance in the channel bottom caused by the constant flow of water.
Unlike hard armoring technologies, PROPEX Pyramattress components are corrosion resistant and promote vegetation, allowing for an increased design life that is environmentally friendly.
The installation of this project was quick and easy because PROPEX Pyramattress and PROPEX Armormax are more easily transported than hard armoring solutions. The systems also install faster than convention methods, saving time and money.

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.
