Basement Waterproofing from the Inside in Danville

Effective foundation waterproofing system to prevent water infiltration, including membrane, interior drain, and sump pump in Montreal, Laval, the West Island, and the South Shore

Sous-Sol Confort is a local contractor specializing in basement waterproofing. We offer a service with our state-of-the-art drainage system, specifically designed to solve water infiltration problems in basements in our region. We customize our systems based on the specific needs of your home, regardless of its age, size, or style.

If you have noticed puddles or seepage at the wall/floor joints or on your basement floor, it is time to invest in a quality waterproofing system. Water infiltration problems in basements never improve on their own and can worsen over time. Even if your basement only gets wet during heavy rains, indoor air quality can be affected, leading to musty odors.

Furthermore, you won't be able to fully utilize your basement without effective waterproofing. Our interior waterproofing systems can be tailored to resolve water issues in any home, no matter their severity.

Basement Waterproofing from the Inside

Clog-Resistant French Drains

Thanks to interior drainage work, this innovative technology effectively waterproofs your foundation while minimizing demolition and often offering a lower cost compared to exterior work.

FlowDrain, our basement waterproofing system with wall drain, is a sub-floor drainage system designed to solve water infiltration problems in basements. It is installed on a bed of stone, adding a clean layer to prevent clogging, ensuring that mud or dirt does not block the system.

By installing an interior FlowDrain system with a wall drain along the inner edge of your basement wall footing, you can capture water at its most common entry point: the joint between the floor and the wall. This way, groundwater will be directed toward a sump pump and then pumped outside.

We dig a trench along the foundation walls and install a FlowDrain with a horizontal wall drain next to the foundation footing, located under the concrete floor. We also install a collection basin with a sump pump connected to the drain and a discharge line.

The system can be equipped with inspection and cleaning ports. FlowDrain with wall drain is a piping system installed inside the basement perimeter, specifically designed to be a highly effective and durable waterproofing solution.

Benefits of Interior Basement Waterproofing:

  • A complete installation of our system, including a sump pump, can be completed in two days.
  • Can be partially installed with approved performance.
  • Additional sealing systems can be added after installation.
  • Compatible with all foundation types.
  • No maintenance required.
  • Can be installed in winter.

Exterior waterproofing requires the use of a mini-excavator, where workers must dig to expose the foundation and reach the footing. If your neighborhood has homes that are very close together, or if there are tight spaces like a balcony or other obstacles, exterior basement waterproofing may not be a viable option. In any case, we strive to carry out repairs in the least invasive way possible.

Basement Waterproofing from the Inside

Features of Our System:

The main difference is that the Flow Drain with wall drain is placed next to the footing, preventing water from touching the concrete slab from below, keeping it dry at all times.

Unlike the other system, which is installed above the footing, allowing water to enter underneath and come into contact with the concrete slab. This can lead to moisture issues and even water infiltration through floor cracks, which are often found in basement slabs.

Our unique system captures water leaks before they reach the underside of the concrete floor, controls hydrostatic pressure, reduces floor moisture, and resolves water infiltration. With our wall drain, you can also capture water coming from walls, cracks, windows, and doors, directing it straight into the drain.

The problem:

Ms. Marie-Hélène noticed signs of water infiltration and a musty smell in her basement. She wishes to be able to use this space without these inconveniences and benefit from optimal comfort.

The solution:

Our experts at Sous-Sol Confort conducted a free evaluation and recommend the installation of a FlowDrain drainage system as well as a SumpPlus sump pump system to evacuate infiltrated water and drain it outside the house, thus achieving a dry and comfortable basement.

To begin the installation of the drainage system, a trench is dug around the internal perimeter of the basement, at the joint between the wall and the floor, to install the FlowDrain drains on a bed of gravel. Then, the floor is covered with concrete.

Once the drains are installed, which collect infiltrated water and direct it towards the SumpPlus sump pump system, a perforated receptacle is installed two feet deep in the ground, as well as a support to lift the powerful pump, a battery-operated alarm that sounds automatically when the water exceeds the level at which the pump should normally start, and finally, a hermetic cover with a floor drain.

The sump pump system then evacuates the water outside the house through an independent SafeGuard discharge line that has been successfully installed.

The problem:

Mr. Sabo has been facing water infiltration issues and a musty odor in his basement, making the space uncomfortable and unusable. He wants to resolve these problems to have a dry and comfortable basement.

The solution:

Our team of experts at Sous-Sol Confort conducted a free evaluation and recommends the installation of a FlowDrain drainage system along with a SumPlus sump pump system to eliminate infiltrated water and redirect it away from the house, ensuring a dry and comfortable basement.

The installation process begins by creating a trench along the interior perimeter of the basement at the junction between the wall and the floor. FlowDrain drains are then installed on a gravel bed within this trench. Once the drains are in place, the space is covered with concrete. Simultaneously, a perforated sump pit is embedded two feet deep into the ground. A powerful pump is mounted on a stand near the pit. Additionally, a battery-powered alarm is installed to automatically signal when the water level exceeds the threshold at which the pump should start. Finally, a watertight cover with a floor drain is secured.

The sump pump system then pumps the water out of the house through an independent SafeGard discharge line, ensuring efficient and safe removal of the infiltrated water.

The problem:

Our client, Mr. Robert in Montreal, was experiencing a persistent problem of water infiltration in his basement. Every year, his foundation allowed a certain amount of water to penetrate, which had gradually deteriorated his wooden floor due to excess moisture. In search of a permanent solution, he turned to the Internet for answers. After comparing various options, his choice finally fell on Sous-Sol Confort.

The solution:

Following the appointment with our specialist, he took the time to fully understand the issue and propose personalized solutions. To solve the problem, our specialist recommended the installation of an interior drainage system such as the French drain and waterproofing the wall with the Delta MS membrane. The Flow Drain system, in particular, was recommended for its ability to prevent the accumulation of debris and soil that can clog the traditional drain. With this system, maintenance and cleaning are facilitated, ensuring optimal operation of the drainage system. Regarding water drainage, our specialist suggested installing a SumPlus pump with a high evacuation capacity. This pump is equipped with multiple alarm systems designed to warn homeowners of potential problems, providing proactive flood protection.

Thanks to the implemented solutions, our client now enjoys a basement secured against floods, while his floor effectively resists humidity and mold.
