What is a French drain?

You may be wondering what this term means. Let’s explore together the definition, features and benefits associated with the French drain.

Simply put, a French drain can be installed in any type of soil that requires a water drainage system. Often referred to as a “dispersion drain,” it comes in the form of a pipe installed at the base of a foundation. Its main role is to facilitate the evacuation of excess water accumulated around a building, thus preventing any water infiltration inside the structure, whether it is a house, a cottage, a building, or other.

In some provinces, such as Quebec, strict standards require the installation of French drains to avoid drainage problems that would otherwise be unavoidable.

French drains, usually made of flexible or rigid plastic, are connected to a watertight sump. In older constructions, there are drains made of concrete or terracotta pipes, connected to each other with a slight opening of about half an inch between them. Cleaning chimneys are also integrated to facilitate the maintenance and cleaning of drains. 

Once the drainage system is in place, the French drain plays a crucial role in preserving the building’s foundation. Any malfunction of the drain can lead to problems for the latter. It is therefore essential to be vigilant as soon as potential symptoms appear.

What are the motivations for installing a French drain? 

In addition to meeting the standards of the province of Quebec, there are many reasons why the installation of a French drain is recommended. 

The French drain, positioned around the perimeter of the foundation, plays a vital role in draining water that may accumulate, helping to reduce the risk of infiltration. As a result, it helps prevent all the problems associated with water infiltration, including mold growth due to moisture resulting from infiltration.

Problems with mold or bacteria (fungus) can take a toll on the health and structure of your property, and repairs can be very expensive.


How does a French drain work?

The French drain is a piping system installed all around your home or building, directly into the ground, preventing water from flowing into the building. It acts as a membrane that deflects water before it reaches your property. 


Causes of French Drain Clogging

French drain obstruction is often due to the deposition of iron ochre in the drainage system under the foundation. This deposit is formed as a result of chemical or biological reactions caused by the oxidation of iron in the soil or groundwater. 

Technical inspection of the French drain

The work will be planned based on a technical inspection. It may be necessary to repair only the section that is causing the problem, or it may be necessary to replace the system completely. The work usually involves excavation to access the failing drain.


How much does it cost to install a French drain?
