How A Contractor Installs A French Drain In Your Basement


If your basement is always damp and musty, it's just a big waste of space. You can't really use it for storage or as a family room when there's always the risk the floor will be wet. The solution is to have a French drain installed in the floor. This routes water towards a sump pump so the floor stays dry. You can then use your basement for playing pool, working on your hobby, or storing your belongings. Here's what to expect when you get a drain installed.

Busting Up The Concrete

The first step to having a French drain installed indoors is to have the contractor dig a trench in the concrete floor of your basement. This is a loud and dusty process, but it doesn't take too long. It is certainly less disruptive than having a drain installed outdoors, which requires digging up your yard. The contractor busts up the concrete all along the perimeter of the basement so that a narrow trench surrounds the room and ends at a small well in the floor. The trench extends into the soil so underground water is caught before it seeps into your basement.

Putting In The Drain

The next step is to put a drain in the trench. The pipe has openings along the top where water can drip inside. Then, when water flows toward your basement, it falls into the drain rather than spreading across the floor. Once the water is in the drain, it flows towards the holding well.

Connecting The Sump Pump

An indoor French drain system usually needs a sump pump to get the water out of the basement. The drain in the floor routes water towards the well and when the water level is high enough, the sump pump is triggered. Water is then pulled out of the well and sent outside of the house. The outdoor drain is situated so the water flows away from your house and doesn't contribute to wet basement problems.

Covering The Trench

The final step is to cover the trench with a new layer of concrete so the drain is invisible. This allows you to put any type of flooring down you want all the way to the walls. The French drain is positioned low enough that it continues to route water towards the pump even though the drain is out of sight. The pipes should never need maintenance, so you won't have to worry about accessing them. The sump pump and motor will be easy to reach at all times so you can maintain and repair the pump as needed.

Your contractor may have other suggestions for installing an interior French drain depending on your situation. For instance, you may only need a drain against one or two walls instead of all four walls. No matter what kind of drain you get, they all work the same way. The idea is to capture the water before it enters your basement, which will leave the floor nice and dry. For more information, contact a basement waterproofing service.

Talking About Concrete Contractors

Hi there. My name is Murray Swanson. Welcome to my website about concrete contractors. When I started my home renovation project, I was stuck on what to do with the area outside my home. I knew I wanted to have a large circular driveway, but I did not know how to proceed with designing the pathways and other concrete structures. My contractors helped me create a perfect design and construct the pathways and driveway for my project. I will use this site to discuss all of the different services provided by concrete contractors. Please visit my website again soon to learn more.
