French Drain Installation Guide

The extra water on your lawn can cause many problems to mosquitos breeding, mold and even lawn damage. Not to mention property owners will have difficulty mowing areas of a lawn that is saturated with water. To solve this problem a french drain installation is used to direct extra water into an area in which a property owner feels it should go. Let’s take a look into how this piece of equipment can be beneficial to your property.

What Is A French Drain?

A french drain is easy to install. The materials needed to fulfill the completion of such a project include you having gravel or rock or a perforated pipe that is able to regulate the flow of surface liquid or bottom liquids to areas you prefer. In most cases, the trench is filed 12 inches containing the gravel.

The good news is a french drain doesn’t have to use the perforated pipe. A homeowner is able to dig a trench and use large rocks toward the bottom portion of the trench and gravel towards the upper portion of the trench. Filler fabric can be placed over the gravel and to protect from sediments.

The average piping diameter of a perforated pipe is 4 inches. This is just about the best size to choose for an area that isn’t overly saturated with water. If your surface area is overly saturated with water a 6 to 8-inch pipe in diameter will do. Be sure to choose a pipe that has a length suitable to reach a ditch or an area you prefer water o evaporate.

Manipulating the position or placement of the pipe can make a tremendous difference in the flow and speed of drainage. It has been proven that a french drain installation installed at a 1 to 3 percent slope drains water much more efficiently.

Performing Maintenance

It’s important to keep your french drain performing at its best. A french drain should be maintained every year. The reason is due to stray soils clogging the perforated pipe, gravel, tree roots, and silt. Silt could be either sand, clay or any material consisting of debris in that size.

An electrical sewer snake is able to clean the pipes of a french drain. This equipment can be rented at your local hardware store. Knowing the size length of your pipes can help you choose an electrical snake that is the proper size. To play it safe rent one that has at least 100ft wound spring cable.

A pair of leather gloves will protect your hands from getting damaged while feeding the cable into the drain. It’s as simple as uncovering the drainpipe and feeding the snake into the pipe. Generally, when performing this task, you will need to pay attention to any obstructions in the pipes. A turn in the drain also lets you know it’s ok to continue moving the cable through the drain. The key is to install the drain correctly to minimize yearly maintenance.

French Drain Fails

Typically, when homeowners hire a professional to install a french drain it’s due to issues already occurring on their property. In this case, it might be a massive amount of water saturating the front lawn for example. The professional company will dig a trench and then follow the steps to install the french drain. Many times, where this process could become a fail is by reusing the same soil or dirt that was dug up. Gravel tends to have great percolation whereas soil or dirt does not. When hiring a professional to be sure to ask questions.
