SOS Drainage
Québec City drainage contractor that replaces French drains and repairs foundation cracks, with emergency service across the city.
What they do
SOS Drainage works on the drainage around Québec City homes. Its main jobs are French drain renewal, which covers excavation around the foundation, replacement of the damaged drain, and backfilling with compacted soil, and foundation crack repair, where cracks are sealed from inside by injecting polyurethane under pressure. A camera inspection shows whether a French drain needs cleaning or full replacement, and inspection chimneys are installed during that work so later checks and cleaning are simpler. The company also offers emergency service across the city, free estimates through an online form, and financing for projects of all kinds. Its work carries a 10-year warranty.
