Pieux Vissés Du Grand Montreal

Pieux Vissés du Grand Montréal is the screw pile division of Entreprises Daniel St-Pierre, a family residential and commercial construction and renovation company based in Saint-Charles-sur-Richelieu, Quebec. The company says it was founded in 1987 and holds the Réno-Maître certification from the APCHQ and membership in the AECQ.

The site says the company has used screw pile anchoring since 1998 for balconies, galleries and stairs. In 2000 it bought a mini excavator and a compact bucket loader so it could use screw piles on more jobs and work in tight spaces. Later equipment allows installation under existing structures, which lets it straighten sagging concrete galleries and stairs and extend houses sitting on damaged sonotube footings. It also digs French drains and builds four-season sunrooms.

The site is in French and gives a phone number and mailing address for contact. Ask for the pile size and depth planned, how installation torque is checked, and whether the quote covers any permits or engineering for your project.
