Overview Of Exterior French Drains
Installing a french drain around the foundation outside of your home is an affordable and effective way to divert water away from the house, and ensure that your basement or crawl space stays dry, especially if you dont have gutters installed on your home. The concept of a french drain is simple: instead of water soaking into the ground up against your foundation or leaking into the egress window wells, you divert the water away from the home using a perforated pipe under the soil, surrounded by drainage rocks which act as a leach field. One of the most common causes of a leaky basement is rain water that soaks into the soil and moisture seeps through basement walls and even up through the floor. This can be avoided with an exterior french drain, which is much simpler and cheaper to install than an interior french drain. A french drain is also great if your yard collects a lot of moisture, or if you see areas that tend to puddle up after rain.
