Fortunately, there are several steps homeowners can take to prevent foundation problems when dealing with clay soil around their foundation, including the following:
Clean gutters and downspouts regularly – Gutters and downspouts are designed to carry water away from the foundation. When leaves and other debris accumulate in gutters and downspouts, they can clog the system and cause water to overflow and soak the ground around the foundation. This excess water adds to the pressure exerted on the foundation by the clay soil, eventually leading to cracks and other damage.
Use downspout extensions – Installing downspout extensions will divert water several feet away from the foundation before release to prevent the ground around the foundation from getting saturated. Downspout extensions are inexpensive and easy to install.
Regrade the yard around the foundation, if necessary – The ground around the foundation should slope away from the house to encourage water drainage away from the foundation. This will prevent the clay soil around the foundation from getting saturated with water and swelling.
Don’t plant water-hungry vegetation next to the foundation – Keeping flowers and shrubs away from the foundation is another crucial step in keeping the foundation healthy if you have clay soil. You don’t want a reason to add water to the ground around the foundation.
Keep trees away from the foundation – Trees planted too close to the foundation can also cause damage due to their root systems. These roots can penetrate the foundation walls and cause cracks, leaving the foundation vulnerable to damage caused by clay soil.
Install a drain tile system – Installing a drain tile system is an effective way to prevent foundation problems when dealing with clay soil. This system works by collecting water from around the foundation and directing it away from the house. This helps to prevent ground saturation and reduces pressure on the foundation walls, preventing structural issues caused by clay soil.
