French Drains & Downspouts

When should you opt for a French drain?

  • When you have a low-lying wet spot or swale in your yard, where water is being trapped
  • When you have wet soils in close proximity to your foundation, causing pressure on your waterproofing system

Whereas gutters collect precipitation as it runs off the roof, French drains manage water at ground level, where water may pool after a heavy rainstorm if there is not appropriate surface grading. A properly located French drain can move large volumes of water out of these areas, protecting your basement and creating a lawn that is usable in all seasons.

French drains are typically several feet deep with a perforated PVC tile at the bottom of a 2’ wide ditch filled with gravel. This allows surface water to escape down through the gravel to the drain pipe. The drain pipe is then trenched in and routed out to a more convenient location on the property, or into the storm drain.

A lot of foundation problems are caused by the lack of downspout drainage. You may have gutters, you may have a downspout, but unless you have an underground downspout drainage system, water is just pooling in the soils around your house and will find its way into the basement. You need it away from your home, its vulnerable entry points, and the foundation. An underground drainage system carries the water to storm drains or dry wells a safe distance away from your foundation.

Why is this important? Moving water lessens the soil saturation around your home, helping avoid clay soil and frost expansion that will, over time, force cracks and bowing into your foundation walls.

At Eco-Seal, solid PVC pipes are used to run our underground drainage systems. This ensures proper slope to the drain and no low sagging areas where the pipe might collect dirt or get crushed easily. We believe in doing things right the first time, and using products that will perform over the entire life cycle of the home.

How do you know if your existing drains aren’t functioning properly? Do you see water bubbling out of the connection from the downspout to the underground drain? Are your gutters overflowing due to clogs somewhere in the system? Are the soils around your foundation sopping wet after a rain? If so, give Eco-Seal a call and we’ll be happy to help.
