A recent study by the Concrete Foundation Association (CFA) shows that 85% of home structural damage is caused by poor drainage. As a homeowner, you appreciate how costly home repair is and as such, it is important to deploy preventive measures to avoid such expenses.
Your home is the most important investment and as such, you need to expend all efforts to maintain it in tiptop condition. Exterior drainage systems offer a timely solution to avert property damage caused by surface water.
Risk of Water Damage
To appreciate the reasons to invest in surface drainage outside your home, you need to consider what can go wrong if you don’t. Surface water causes lateral pressure against foundation walls. The consequences include:
- Foundation cracks which compromise the integrity of the house.
- Basement leaks leading to flooding and property damage.
- Health risks caused by mold growth in the basement.
- Loss of home value due to water damage
- Damaged landscape
These problems highlight the need for exterior drainage to keep water away from your yard and the foundation walls. Below are some systems a contractor can use to solve the problem of poor surface drainage:
- French Drain
This is a perforated pipe that is installed in a flat yard to drain away standing water. It involves excavating a trench that slopes away from the property and the pipe is then installed. A porous material such as gravel is used to fill the trench before the trench is finally covered. Standing water follows the easiest escape route meaning it will seep down to the French tile and drain away from your yard.
- Footing Drain
This is a highly effective water drainage system. A pipe is installed around the perimeter of the foundation walls on level with the footing. This pipe collects any water that would have leaked through the top of the footing into the basement and drains it away from the foundation walls. The drain is covered with gravel up to the soil’s surface.
- Gutter Drainage System
Roof water can cause havoc if not well drained. A gutter and downspout system help drain away all roof water away from the house walls. The downspout drain should extend away from the walls and preferably direct the water to a storm sewer or catch basin.
- Grading Drainage
This is a simple technique that involves reworking the grading in order to slope away from your house. A contractor will assess the gradient needed to drive water into the storm sewer within the building code.
