The moisture in soil causes it to contract and swell with the weather. This causes the soil beneath your house to move up and down. As a homeowner, you can stop the rise and fall of your foundation by installing a soaker hose. Then, by following a controlled watering program, you can keep the moisture content at a constant stage, ending the movement of your foundation. If you don't fix the problem, the result could lead to uneven floors, cracked walls, doors and windows that do not open or close properly.
Dig a 3-inch-deep trench 8 to 12 inches away from your home's foundation. Dig this all the way around the foundation. You don't want to put it right against the foundation. If there are large cracks in the dirt, the water will run along the cracks for several feet in all directions. It could puddle up at the bottom of a grade beam. This may cause the soil to lose some of its load-bearing capacity. If this happens, your home could sink.
Lay the soaker hose in the trench you just dug.
Hook the end of the soaker hose onto a short piece of solid hose and then connect this to the outdoor water spigot or fountain.
Bury the soaker hose. Connect as many soaker hoses as you need to go around the foundation of your home.
Turn the water on. Run the soaker hose more during the hot, dry weather conditions, and less when the weather is cold and damp. The amount of water you will need varies from house to house. It depends on how big the foundation is, how many plants you have growing close to the foundation, and how many trees or shrubs are there. One large tree can take as much as 150 gallons of water from the soil every day.
