How Do I Keep My Driveway From Flooding?

How do I keep my driveway from flooding?

You have a beautiful driveway, but every time it rains, your drive floods. This means you don’t have good driveway drainage. When your drive is continually inundated by rain, in time your drive can be subject to damage such as cracking of your asphalt or concrete. That damage often leads to expensive repairs. There are solutions, however, to your flooding problem that won’t break your bank. Two popular options include either installing a channel drain or a drainage swale.

  • Channel drain: These are narrow drains and work similarly to gutters, directing water away from your drive. The channels can be open or closed, though closed models are best to keep dirt and leaves out the drain.
  • Drainage swale: Swales follow the contours of your drive and divert water from the drive in a similar way as channel drains.

Does my driveway need drainage?

Whether you’re planning to build a new drive or you already have a drive in place, driveway drainage is essential if you want to ensure your drive lasts a long time. Water can quickly cause all kinds of problems for your drive if you have no way of diverting it. Both concrete and asphalt will crack over time and the soil surrounding the drive erodes and wears away the drive’s foundation. Pooling water can discolor the drive or cause algae to grow. All of these problems can lead to costly repairs. 

If you already have a drive in place, you can improve drainage by creating swales or install gutter-like channels. These are also options for new drives, although the best solution for new drives is properly grading the drive so there is enough of a slope created so water washes from the drive rather than pooling on it.  

How do you drain water from a driveway?

If you are having trouble with driveway drainage, there are several driveway water drainage solutions. Among those solutions:

  • Effective placement and slope: When building a new driveway, try to place it in an area that has good drainage and not in a low-lying area. Also, make sure the grade is steep enough it will drain properly.
  • Install a trench or French drain: In some areas drainage will be poor even if you have a good slope on your drive. Adding a trench or French drain is a good solution for these areas. These are channels that go across the width of the drive and are covered by a grate.
  • Create a swale: This is a wide but shallow depression in the ground that diverts water from the drive. Swales are good when you have natural slopes.
  • Use permeable or porous material: Concerns about drainage can be addressed by using a permeable or porous material in the drive’s construction. With permeable material, water passes through voids in the material to the soil beneath.

How does driveway drainage work?

When you install structures like channel drains on your drive, as part of your driveway water drainage system, they work similarly to gutters. Water drains off your drive into the channel as it would into a gutter on a roof. There are two basic channel drain designs, ones with built-in falls, and ones with a standard depth. Large parking areas often employ drains with built-in falls that keep the water flowing away from the pavement. Channels with standard depths often work best when an area has a natural slope. Both types of drain rely on gravity to move the water through them.  

Driveway drainage on a hill

While you want to have a good slope for driveway drainage, when you have a drive built on a hill, you can still have problems with drainage and pooling, especially along the bottom of the drive. To alleviate some of these drainage problems you can add a swale alongside the drive. Swales follow the natural contours of the drive. They are dug shallowly enough so that they won’t accumulate water. 

Driveway grates for drainage

When you install channel or French drains, drain grates cover the channels and help keep dirt, leaves, and other debris from clogging the channels. The grates are made from a variety of materials ranging from hard plastic to cast iron to stainless steel. What kind you choose will depend on how much traffic your drive gets and what matches your driveway’s style and design. The grates come in a variety of colors as well as different designs.
