French Drain Systems - Professional Installation in Toronto

Eliminate basement water problems with Toronto’s most trusted drainage experts

A properly installed French drain system is your foundation’s first line of defense against water damage. At DrySpace, we’ve perfected French drain installation through 25+ years of protecting Toronto homes from water infiltration.

What is a French Drain System?

A French drain is a gravel-filled trench containing a perforated pipe that redirects surface and groundwater away from your foundation. This time-tested solution has protected homes for over 150 years and remains one of the most effective drainage methods available.

How French Drains Work

1. Water Collection: Perforated pipes collect water from surrounding soil
2. Filtration: Gravel and fabric prevent soil from clogging the system
3. Transportation: Gravity moves water through the pipe network
4. Discharge: Water is directed to safe drainage areas away from your home

Why Toronto Homes Need French Drains

Local Water Challenges

Toronto’s unique conditions make French drains essential:

• Clay Soil: Our heavy clay doesn’t absorb water well, creating pooling
• Spring Thaw: Rapid snowmelt overwhelms natural drainage
• Urban Density: Limited green space reduces natural water absorption
• Aging Infrastructure: Overburdened storm sewers need supplementation
• Climate Change: Increasing rainfall intensity requires better drainage

Signs You Need a French Drain

• Water pooling around foundation after rain
• Soggy spots in your yard
• Basement dampness or flooding
• Foundation cracks from hydrostatic pressure
• Efflorescence on basement walls
• Gutters overflowing despite being clean
