INTERIOR FRENCH DRAINS
When it comes to pushing the water back outside or into a drain line, trust the team at Akton Injection to install interior French drains in Montréal, South Shore, West Island, and Laval. This drain will not only prevent the water to enter your basement but also catches the water that seeps inside and pushes it back outside with the help of a sump pump. Interior French drain is an ideal solution for pooling water, such as rainwater or snow resulting in foundation crack.
While installing interior French drains, our team will remove and replace the concrete. We will install 4” French drain with geotextile and 3/4 net gravel. Interior French drains are installed beside the footing to collect water and lower the water table, unlike gutter system that collects only water.
INTERIOR PERIMETER DRAIN
Interior perimeter drains or "French drains inside the basement" around the perimeter of the foundation footing is the great line of defence against groundwater if you cannot install an exterior French drain. The installation of an interior French drain is a secondary solution because it gives you a dry basement but does not protect the foundation walls against future deterioration. Membranes on the outside of the foundation cut off wear and tear from water pressure.
Interior French Drain Installation
To create a French drainage system inside your home, we first breakout the basement floor along the perimeter of the wall, all the way besides the footing of the foundation. Then, we clean out and slope a trench to the sump pump pit that we create. A dimpled plastic membrane called Delta®-MS is installed fully sealing the foundation and directing incoming water into the trench. We install a perforated French drain around the perimeter to direct the water into the sump pump pit. The trench is filled with 3/4 inch clean gravel to protect the drain and help the flow of the water. Finally, the floor is re-cemented and our staff removes any excess debris.
