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.
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.
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.
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.
