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?

Prevent water infiltration

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

Improve indoor air quality

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

Protect the structure of the house

The installation of an interior drain prevents moisture from accumulating and entering the walls or floors. This protects the foundation and the structure of the house from erosion and water damage, avoiding costly repairs in the long term.

Increase the property's value

The installation of an interior drain can increase the value of the home by ensuring protection against water infiltration. Additionally, it optimizes the use of your basement, which can be finished without the risk of moisture or mold, thus increasing the livable space.

Interior Drain Installation

1. Trench along the foundation

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

3. Installation of the sump pump

We install a sump pump to collect the water gathered by the French drain. This sump pump will be connected either to the stormwater system or the sanitary 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 dug trench, positioned to capture the water infiltrating the foundation. The drain is placed at the foundation footing level to effectively direct the water to a drainage point.

4. Backfilling and pouring of the concrete slab

Once the drain and sump pump are installed, we proceed with backfilling the trench with gravel and pouring a concrete slab to finalize the installation. This step ensures the stability and integrity of the system while restoring the appearance of the interior floor.
