Economical Approaches to Foundation Drainage Economical Approaches to Foundation Drainage

Foundation drainage keeps water away from your home foundation. It is important for several reasons. It is a good idea to know why this is helpful and what you can do to get the most out of foundation drainage.

Importance

One of the biggest reasons that foundation drainage is important is your land should stay dry. That is especially true if you live in a flood prone area. Waterproofing is something else that you can do to help keep your land dry. Soil needs a foundation so that it can stay at consistent moisture level. which prevents settlement, differential movement, and heave. Building codes also require foundation drainage.

Requirements

Building codes state that foundation drainage is necessary. If the soil in your area does not drain well, then you will need to think about ways that you can have foundation drainage. You will need to look at the international residential code for a list of the drains that will work. It is important that you view this list so that you can get a drain that will match both your financial means and your residential needs.

Moisture

When it comes to subsurface moisture, there are 2 different zones. which are the saturation zone and the aeration zone. The saturation zone is anything that is below the water table. The water table is the level to which water rises in a well. A saturation zone is not often an issue when working with residential construction. Soil moisture is typically the problem.

Surface Drainage

To control the soil moisture beneath your foundation, you must control the surface water. The ground surface should slope away from your home between .5-inches to a 1-inches for 10-feet. A poorly completed compacted backfill well will create problems.

Types of Drainage

Gutters are inexpensive and can do a lot for drainage issue. You will be able to discharge any sloping surfaces that are 10-feet from your foundation. Wherever this isn’t possible, use downspouts will need to be discharged into catch basins.

Trees

Trees will need to be planted no close to your foundation than what their eventual height will be. That is necessary so that the tree do not impact the perimeter drains. It will also keep the tree from taking all of the water out of your soil, thus preventing settlement. It is a good idea that whenever you are planting trees, you know how tall they will eventually be so that you will know where to plant them.
