The largest borough on the West Island, Pierrefonds-Roxboro was hit hard by the 2017 and 2019 floods. Its 1970s-90s suburban homes, built on clay soil near the Rivière des Prairies, require a vigilant inspection.
Pierrefonds-Roxboro borders the Rivière des Prairies to the north and offers a vast residential territory primarily developed between 1970 and 1995. The area saw strong growth in the 1980s, with thousands of homes built on former farmland. The catastrophic 2017 floods highlighted the vulnerability of certain areas and deeply marked the local housing stock.
Pierrefonds soil is composed of a mix of glacial till and Champlain Sea marine clay, with alluvial deposits near the Rivière des Prairies. The lowest areas are naturally wetlands that were backfilled for construction, creating particularly difficult conditions for foundations and drainage.
Our expertise in flood zones and Pierrefonds clay soils enables us to identify critical problems that might otherwise go unnoticed.
We inspect properties throughout Pierrefonds-Roxboro, including:
1960-2000 single-family homes, Rivière des Prairies waterfront properties (2017/2019 flood zones), marine-clay sectors, new developments — Pierrefonds-Roxboro is a residential sector marked by documented flooding concerns.
