How Can You Improve Downspout Drainage?

Every single homeowner needs to understand the importance of a house’s gutters. Just 1 inch of waterfall actually drops 623 gallons of water on a roof if the house is 1000 square feet. All this goes through the downspouts. All the water going through downspouts can potentially cause expensive and serious foundation and flooding problems when collecting around a house.

In order to prevent damage, there are some simple solutions. Summit Gutter Installation Denver highlights some of those that have to be considered.

Add Extenders To Downspouts

When there is soil that is well-drained that slopes away from a foundation, extenders are usually all that is needed to improve overall drainage. Two types exist:

These are extenders you can twist into practically any angle for all possible purposes, including moving downflow away from your home.

The extensions have to end on splashblocks. Usually, cement and plastic splashblocks are not installed but they are useful since they spread water. Direct pooling under the downspout is thus avoided.

Use Pipes To Move Water From The House

In order to divert the water even farther away from your house, the French drain or some other trench drainage systems need to be considered. The French drain is practically a trench that is sloping from the home, thus emptying right onto open ground. This happens far away from the house.

The bottom of a trench has to be filled with gravel. Then, a solid or flexible pipe is added. More gravel is put on top, then soil and sod. In the past, French drains did not have a pipe but you can now create a more hybrid system with the use of a quality porous pipe.

Burying Drainage Pipes

When the yard does not slope enough and you cannot use the French drain system, a complex pipe trench is needed. There are many municipal ordinances where you cannot allow the homeowner to attach the downspout pipes to a storm sewer system. Even so, an underground drainage system can be built.

Install Diverters

Last but not least, the diverter can easily be used in a conjunction with all the other methods highlighted above. However, they are not a standalone solution available for the homeowner to deal with drainage issues.

A diverter will draw the water into rain barrels from downspouts. The rain barrel can then be utilized to water your garden or to just spread the water. Harvesting rainwater is a wonderful way for a homeowner to collect water. However, this does come with some legal concerns and health warnings.

The rain barrel is not going to fully capture water flowing from the roof during heavy rainstorms. It is always better to use a diverter since it allows overflowing back into downspouts, all spilling right into the ground. Piping and extenders are still needed to alleviate drainage problems.

Final Thoughts

Downspout drainage can be really simply improved or it can be quite complicated. You can add an extender or burry a barrel. No matter the case, all the methods are way simpler and cheaper than fixing some really serious foundation problems caused by rainwater the pools around a house.
