How long does an interior French drain last?

The lifespan of a well-installed interior French drain can exceed 30 years, especially if regular maintenance is performed and the system is well-ventilated.

Can an interior drain be installed in an existing house?

Yes, it is completely possible to add an interior French drain to an already built house. This involves digging a trench inside the basement, along the foundation walls.

What is the difference between an interior drain and an exterior drain?

The interior drain is installed inside the basement and captures water that has already entered, while the exterior drain blocks water at the source before it reaches the foundation. The choice depends on the building's configuration and budget.

In which season should an interior French drain be installed?

Since the work is done indoors, it can be carried out year-round, regardless of the weather.

Does an interior drain prevent moisture in the basement?

Yes, it helps drain accumulated water under the concrete slab and reduces moisture and the risk of mold in the basement.

Do you also install sump pumps?

Absolutely. The installation of a sump pump system is often integrated into the interior drain project to ensure effective water drainage.

Why install an interior drain?

Preventing water leaks

An interior drain captures and removes water that could seep into the foundation. It is particularly effective for basements prone to moisture problems or leaks from the walls or floor.

Improve indoor air quality

An effective interior drain helps maintain a dry environment in the basement. This reduces excessive moisture that can lead to mold problems and improves indoor air quality, creating a healthier environment.

Protecting the structure of the house

Installing an interior drain prevents moisture from accumulating and penetrating the walls or floors. This protects the foundation and structure of the house from erosion and water damage, preventing costly repairs in the long run.

Increase the property value

Installing an interior drain can increase your home's value by protecting it from water infiltration. Furthermore, it allows you to optimize the use of your basement, which can be finished without the risk of dampness or mold, thus increasing your living space.

Installation of an interior drain

1. Trench along the foundation

The first step is to dig a trench all around the inner foundation of the house. This trench is necessary to install the drainage system and will allow direct access to the areas where water needs to be collected and drained.

3. Installation of the sump pump

We install a sump pump to collect the water from the French drain. This sump pump will be connected to either the storm sewer system or the sanitary sewer system, depending on local regulations and the specific requirements of your area.

2. Installation of the French drain

We install the French drain in the excavated trench, positioned to capture water seeping into the foundation. This drain is placed at the foundation footing level to efficiently direct the water to a drainage point.

4. Backfilling and pouring of the concrete slab

Once the drain and sump are installed, we backfill the trench with gravel and pour a concrete slab to complete the installation. This step ensures the stability and integrity of the system while restoring the appearance of the interior floor.
