Installing an inner peripheral drain

Accueil » French Drain Specialist » Installing an inner peripheral drain

The interior perimeter drains or “French drains inside the basement” around the perimeter of the foundation sole are the best line of defense against groundwater if you cannot make an external French drain.

The reason we suggest this method as a secondary solution is that an indoor French drain gives you a dry basement but does not protect the foundation walls from future deterioration.

Membranes outside the foundation prevent wear and tear due to water pressure.

Indoor basement systems

The  Inland French drains are installed next to the sole to intercept groundwater before it enters the building and not just a gutter system that collects water after it has flowed into the wall. The BNQ drain against the iron ochre is perfectly compatible with this option. 

In our experience, we have seen that water comes from two sources: water that passes through the wall OR groundwater rising from under the concrete slab.  Our system covers both of these issues.

Drain Franças inside

 

Installing a French drain inside

To create a French drainage system inside your home, we first dig the basement floor along the perimeter of the wall, all along the foundation sole.

Then we clean and tilt a trench to the pit of the sump pump we create.  A dimpled plastic membrane called Delta-MS is installed to completely seal the foundations and direct incoming water into the trench.

We install a French drain perforated around the perimeter to direct the water into the sump.  The trench is filled with 3/4 inch clean gravel to protect the drain and facilitate the flow of water.

Finally, the floor is re-cemented and our staff removes any excess debris.

Deal with a Quebec contractor who specializes in foundations and   whose 20 years of experience in concrete work provides you with sustainable structures and repairs.

Questions sur la réparation de fondation à Gatineau

Faut-il quitter les lieux durant les travaux?

Non il n’est pas nécessaire de quitter lors des travaux. Bien qu’il soit possible qu’une tranchée profonde surlonge tout le périmètre de votre maison durant les réparations, nous avons des installations sécuritaires pour que vous puissiez rester à la maison. Des rampes d’accès sont installées afin de permettre au client d’entrer et sortir à leur guise.

Peut-on baisser le taux d’humidité dans un sous-sol en réparant la fondation?

L’imperméabilisation et la pose d’un drain français protègent en effet votre sous-sol de l’humidité. Si la ou une des sources d’humidité  provient d’une faille de votre mur de fondation, la réparer va contribuer à régler le problème.

Les membranes installées par VOPAA inc. ont des propriétés imperméables et pare-vapeur afin de garder un sous-sol bien au sec. Sachez qu’un taux élevé d’humidité contribue à la formation de moisissure qui peut causer des problèmes de santé importants.

 

Vous pouvez toujours vérifier d’autres éléments tels que la plomberie et les fenêtres qui peuvent également représenter la cause d’une forte présence d’humidité dans l’air.
