The Context

A complete solution in HDPE offered by Soleno

The construction project of the Candiac Square, the second most important residential project of Greater Montreal in 2016, represents a successful achievement using products made of high-density polyethylene (HDPE). Executed over a three-year period, the development of two underground retention system and a complete network of HDPE storm water sewer and treatment system meeting the municipal and provincial governments requirements for storm water management was a first for the various stakeholders of the project. The benefits of this economical, simple and fast installation system won over them to install the first storm water sewer network completely in HDPE.

The Storage Solution

For each of the two 16 rows retention systems, nearly 480 HydroStor HS180 chambers were installed on a stabilization geogrid, and then surrounded by clean stone covered with TX-90 geotextiles. The first retention basin will store 2,505 m³ (88,463 ft³) of water for heavy rain events, and the second retention basin will store 2,475 m³ (87403,8 ft³) of water. A waterproof geomembrane as well as two protective geotextiles were installed on the two excavated areas, measuring 35,27 m (115.7 ft.) in width and more than 66 m (216.5 ft.) in length.
