French Drain

Are you facing problems with water infiltration in the basement? Do you see the formation of various dangerous fungi? Is the humidity level in your home very high? Do you notice changes in the floor level or that it is lifting? Do you see that there is swelling in various areas of the walls and floor?

If you are concerned with any of these challenges then you need our French drain installation services. It is a method of harnessing gravity to divert water from a home. This is possible thanks to the creation of a path allowing the water to move. The French drain forms a small ditch in which our experts install a pipe. The water can then travel through the hose and is kept a safe distance from your home.

In addition, our company has developed high-performance techniques to perform all your work in compliance with industry standards. By entrusting us with your projects, you are sure to benefit from quality work and sound advice in this area.

Our Technique

  1. The first step is to add or repair a drainage system around the foundations to eliminate water infiltration and wet basement problems.
  2. French drains must lead water to a sewer, ditch or well. We therefore install at the base of the soles to facilitate the collection and redirection of the water.
  3. French drains, or perimeter drains, have a minimum diameter of 4”. They are lined on all sides and on top of at least 6” of crushed stone. They are covered with a geotextile membrane to prevent the accumulation of debris that could quickly clog the drain.

Collection Well

Capture wells or infiltration wells are structures that allow surface runoff to be evacuated through underground pipes. Unlike other types of wells, collection wells do not have a water inlet directly on the ground surface. Their absorption capacity comes from installing porous materials and a serpentine drain below the soil surface in order to continue cultivating the soil above.

Several materials can be used to filter the water build-up. This is for example stone, wood chips or straw. It is also necessary to take into consideration that the choice of material affects the longevity of the collection well.

Stone is a more expensive material. However, it ensures increased longevity. As for the straw, which offers a more economical solution, it decomposes quickly. The use of wood chips depends on its availability in different regions. In terms of decomposition, wood chips are a better alternative to straw.

Window Well

A coping is essential to avoid problems of water infiltration and humidity in the basement. It is a protection made of steel, stone, concrete or wood. A coping is attached to the foundation to retain the soil. It helps prevent the floor from being too close to the window.

It is recommended that you create a space of at least 8 inches between the windows and the floor. Adequate clearance must also be provided before installation. This space serves as an emergency exit and helps prevent water infiltration that can cause more costly damage.

Our Skills

Installing window wells requires extensive knowledge of the Quebec Construction Code and municipal standards. Our team has solid knowledge of these regulations and is able to put them into practice. We are therefore qualified to assist you in all your window well installation procedures. Our operators can get your jobs done with unmatched speed and precision.

Our Techniques

We have developed some techniques for the safe installation of copings:

  1. Dig around the window a space 10 to 14 inches deep below the base of the window
  2. Create an 8 inch distance on each side of the window
  3. Install the well above the height of the finished floor
  4. Make sure that the well is centered in relation to the window
  5. Proceed to the shoulder of the coping on the wall
  6. Draw holes to define the location of the holes to be drilled
  7. Fill the bottom of crushed stone up to 6 inches below the bottom of the window

Although these methods seem very intuitive and easy to perform, you absolutely need the intervention of an expert. Because he has the experience, the right tools and knows industry standards. This assures you of quality results and a sustainable investment. Now call on our team in the greater Montreal area to receive a free quote for your projects.


Pyrite is a mineral that is often found in the crushed stone of the embankment at the level of the foundations. Year after year, pyrite comes in contact with oxygen and can create harmful chemical reactions. These reactions cause the backfill to swell.

Do you notice any cracks in the concrete? If you answered yes to one or more of these questions, it is imperative to call in professionals for pyrite decontamination.
