If you live in an area that is prone to flooding or where there is a high water table, it is essential to divert the excess water, using an exterior drain tile. Otherwise, water could seep into the foundation of your home or basement, causing mold and other damage. An exterior drainage system moves the water away from your home, allowing it to be used for other purposes, if needed.
How Does An Exterior Drainage System Work?
First, a narrow trench, at least 24 inches deep, will be built around the entire foundation. Tiny pieces of broken gravel or rock will be placed on top of a perforated pipe. This pipe will allow any water that is present in the soil surrounding it to to be evacuated.
A more sophisticated option that has become popular in recent years includes the use of a gravel substitute. The gravel substitute, that often weighs less than natural rocks, is wrapped around the pipe. It is covered with an inexpensive filter fabric and then covered again with the soil.
Why Do You Need This Type Of System?
An exterior drain tile system is often needed as the result of fluctuating water levels in the soil. When the water level is too high near a building of any type, as previously mentioned, water and mold damage is probable. It is not unusual for nearby land to have inadequate access to water, so it makes both financial and environmental sense to allow the excess water to be used there.
Therefore, the use of an exterior drain tile system, also known as a French Drain, provides water for landscaping, animals, crops, and so forth. Different versions of this concept have been used successfully for many years, with noted improvements in pipes being one of the most significant changes. Gravity forces the water away from the building, assuming that it is not an entirely flat surface.
If the area is not flat, the use of a sump pump may be needed. The sump pump removes water and uses a pipe that is at least 10, but preferably 20 or more feet long to relocate it to a safer location. If gravity is not sufficient for the task, a sump pump will always be needed.
In conclusion, standing water in and around a home is rarely a good idea. Fortunately, an exterior drain tile system is a common, easy way to protect your property against flooding and high water tables. For more information about exterior drain tile, visit Rite-Way Waterproofing.
