How to Improve Drainage Around Your Foundation
The
foundation itself is rock solid, but when everything around the foundation is
unstable, it begins to cause problems. While soil shifting can happen for a
number of reasons. Most commonly, soil shifts and foundation problems occur
because the soil around your foundation gets too wet. This can cause erosion
and hydrostatic pressure that will cause damage.
The good
news is that standard home construction already comes with many ways to prevent
excess moisture from puddling near your foundation, but they are not
necessarily permanently effective. If you are having drainage issues near your
foundation, here are some avenues you can explore to improve drainage.
Landscaping
This the
simplest change you can make to help drainage near your foundation. Plants not
only absorb water that does fall by your house more efficiently, but plant
roots also help stop soil erosion. Landscaping by your home does quite a bit
for foundation health, which is one of the reasons it is so popular.
Downspout
Extensions
Keeping your
gutters and downspouts clear is a good way to promote good drainage, but if you
still find water pooling right up alongside your home, you may need a downspout
extension. This makes sure the water is ferried further out so it is not right
up against your home.
Re-Grading
While you
may not see it, the soil starting at your foundation actually gently slopes
away from it. This helps naturally promote water to drain away from a
foundation. However, over time this grading can wear down, especially if you
have had puddling or gutters overflowing in the area. The slope will need to be
manually built back up.
Trench
Drain Installation
This is the
final solution to many drainage issues in a yard. A trench drain, or french
drain, is a drain installed underground that collects water in an area prone to
pooling, then takes it elsewhere. It can help solve water that just will not
stop pooling by your home.
