Important Information About French Drain Systems

Posted on

Have you recently purchased a home with a basement? Does the basement seem to flood relatively easily? Even if your basement seems to be well built, a heavy rain can still bring puddles of water into your home. If you want to keep this from happening, it may be time to look into installing a French drain system. But before you make any firm decisions, it's a good idea to know your options. Here are some things you may be wondering about French drains:

What are the advantages of an interior French drain system?

If the local water table is naturally high in your area, you may be wanting to prevent water from seeping up through your floor and into your basement. Under these circumstances, your best option may be an interior French drain system. This system will collect and divert water that travels up from the ground, sending it into a sump well. Once in the well, a sump pump will dispose of the water so that it doesn't damage your basement.

Would an exterior French drain system be a better option?

If your basement only floods when it rains, water could be seeping downwards through your basement walls and windows. One obvious symptom of this happening is that your walls will often be moist or seem damp to the touch. If the water is coming up from the ground, the walls are less likely to be damp. With an exterior French drain system, the workers will dig a graded trench around the perimeter of your home. This trench will then be filled with crushed rocks and a pipe that will carry away the excess water. This will help to get rid of any rainwater before it has a chance to even enter your basement, keeping it dry as a result. 

Can you get both an interior and exterior French drain system?

If your area has both excessive water and a high water table, having an interior French drain installed in addition to an exterior one may be the best way to keep your basement as free from moisture as possible. The exterior system will divert as much water as possible away from the house, while the interior drain will get rid of any moisture that does happen to get inside. Such a system working in tandem may be able to keep your basement almost entirely free of any water. Unfortunately, a dual system like this will obviously cost more money than having just one or the other. As a result, you should consult a professional, like those at Perma-Dry Waterproofing & Drainage, Inc., in order to determine if this is something your house actually requires
