The French drain is the basis of the protection of afoundation. Its effectiveness is as importantas waterproofing your foundations.
A French drain is a system of perforated pipes that capture groundwater runoff around the house and is located near your Foundation. It helps to keep moisture, runoff, water infiltration,out of the foundations.
Many models of these tubes are available on the market, some less effective than others. Vopaa Inc. uses a high-quality BNQ drain in accordance with the latest standards and the Quebec Construction Code
This type of drain does not crash and allows a better flow than the traditional agricultural drain.
These are 10-foot (3 m) pieces that are being interlocked to design the system, a drainage system that runs along the foundation wall. Generally, a 4-inch (10-centimetre) diameter duct is sufficient to capture water and clean up the immediate proximity of the foundation walls.
The pipe should rest at the bottom of the trench and rest on unreworked or compacted soil to maintain proper leveling. With its field expertise, the VOPAA Inc. team levels the base where the drain will lean to optimize the flow, pipe and drainage of water.
For an efficient system, the entire network must eliminate any slope, be “level” and perfectly horizontal.
The French drain must be located in below the top surface of the sole [exactement un pouce plus bas]. This allows the capture of a maximum amount of water and prevents it from approaching the foundation.
Once installed, the hose/drain is covered with draining crushed stones to make it easy for water to get there.
A geotextile membrane [le feutre] is then installed on the stone and not on the drain to prevent fine particles from getting lodged in the duct and eventually blocking it.
Then comes the earthworks that replace the embankment and leave nothing glimpse of the drainage pipe system other than some access to the maintenance chimneys hidden between your plants.
All of this drainage work takes between 3 and 6 weeks. As this article explains, the price of the work depends on many parameters that require the visit of the site manager on site.
Water drainage
Water collected by the drainage system like a gutter must then be discharged to a collector
- a ditch,
- The public stormwater recovery system,
- a dry well,
- a sump.
VOPAA Inc. Checks the municipal regulations for your site and ensures that it complies with environmental legislation related to water management in the territory.
There are mainly two possible options:
- Evacuation by gravity
- Mechanical evacuation
How are rainwater managed?
Rainwater includes
- rain, snow, hail,
- runoff,
- roof water
Gutters and gutters work in concert with the rigid French drain to prevent rainwater from accumulating near the walls of a building.
Gravity evacuation in Gatineau
This is to send the water to a point lower than the level of the drainage system. We choose this option when the nature of the terrain and the geological configuration allow, this technique avoids the installation of a hydraulic pump.
This alternative, on the other hand, requires a major excavation. This work consists of digging a drainage trench slightly lower than the level of the French drain up to the spill zone.

The second option is to install a catchment [un « puisard »] basin which will collect water from the French drain, thanks to an electrical mechanical pump that lifts it up and discharges it, the water is then discharged into natural channels or by the city’s river water recovery system. (sewers, pipes)
The basin must be installed at a lower level than the concrete [la chape de la maison] slab. In fact we usually position it inside in the basement.
Is your French drain clogged, blocked?
A regular inspection is used to check the proper operation of the collector, the connection and the pipes in general.
Blocking, clogging the French drain depends on different causes and factors:
- Accumulation of deposits, fine or gravel materials, gravel, pebbles
- Feror ochre formation
- Root or plant penetration
- type of soil [clay, limestone, etc.]
- Non-compliant installation
- Pump malfunction
Annual maintenance of the drainage system in Gatineau
To avoid obstruction and lengthen the life of your drain, we recommend regular pipe inspections and periodic cleaning. The frequency of this interview is determined with the professional according to the context of your installation Vopaa specialist of the French Drain recommends an annual visit just after the fall.
For this maintenance a high-pressure cleaner is used and cleaned via the various maintenance chimneys installed during the implementation of the French drainage/drain network.
