Saskatchewan Crescent - 17th Street Slope Remediation

Site Location

Cracking in the roadway and upper Meewasin trail at 17th Street and Saskatchewan Crescent began to form in June of 2012.  Construction started in the fall of 2013 to remediate the riverbank slope to reduce the risk of future instability at this location.

Riverbank remediation at the intersection of Saskatchewan Crescent E and 17th Street included:

  • Installation of drainage pipes to reduce groundwater levels
  • Placement of expanded polystyrene (EPS) foam blocks below the excavated roadway 
  • Reconstruction of the new roadway and upper Meewasin trail above the EPS foam blocks 

A total of 698 EPS foam blocks, spanning 70 meters along Saskatchewan Crescent, were used in the remediation. The blocks are much lighter than the riverbank soil, reducing the risk of future riverbank slumping at this location. The project was the first in Saskatoon to use this new technology in construction.

Project Timeline
