Your home is typically built on a concrete foundation. Which is why issues like soil erosion can affect the structural integrity of your entire home. As the foundation shifts, a ripple effect will happen. You will first see damage in your interior walls, along your bricks outside, spread across the ceilings and the roof and can potentially damage critical systems like plumbing and electricity.

We often get questions from homeowners about how to stop soil erosion around their foundation. In this blog, we’ll review what soil erosion is, common causes, and how expert drainage solutions can help you prevent it from making your home unstable and unsafe.

What is Soil Erosion?

When soil erodes, it draws away from your foundation walls. In Georgia, the main cause is running water. As the soil erodes, water can pool by the foundation instead, increasing the risk of the following problems.

• Water ingress: When water collects against the foundation, it can gradually get into your basement or crawl space through any cracks created by soil movement or substandard construction. Soon you will notice dampness, mold, a musty odor, or water pooling on the floor.
• Increased pressure: As water accumulates, it applies pressure to the foundation walls. That pressure disappears when the water dries, but the ongoing back-and-forth movement can cause the foundation to shift and crack. With the amount of rain Atlanta gets each year, this can escalate the problem exponentially.
• Foundation settling: A damaged foundation can settle. If that happens, you may notice cracking in the walls and outside brickwork, uneven floors, and sticking doors and windows. 
• Moisture damage: If water gets through your foundation, it can travel through the walls to the upper floors and destroy flooring, baseboards, and the walls. Exterior drainage solutions will help stop the moisture from getting through to your foundation and relocating it away from your home.

How Can You Stop Soil Erosion Around Your Foundation?

The best way to protect your foundation is to prevent soil erosion from occurring in the first place. We recommend the measures outlined below. Venyscapes offers expert drainage solutions that can quickly stop soil erosion around your foundation.

1. Install a Surface or French Drain

Surface drains and French drains are common and effective solutions to drainage issues.  The main difference between the two systems is that surface drains are designed to clear away water pooling on your lawn’s surface while French drains handle water that’s seeped below ground level.

If the soil around your home is prone to oversaturation after heavy rainfalls, a French drain can clear away excess water so that it doesn’t damage the foundation walls or get under your slab foundation and cause heaving. A surface drain may be the better choice if your lawn slopes toward the foundation and water always accumulates during rainy weather, as they can clear away large volumes of water in a short amount of time.

2. Correct the Foundation Grading

Does the soil around the foundation have sufficient slope to prevent water from collecting against the wall? A good rule of thumb is a ground slope of 3% to 5% for the first 10 feet surrounding the property. If your property layout doesn’t support this recommendation

On top of the abovementioned tips, you also need to ensure that the soil around your home has a proper slope. Experts recommend that the ground around your home has a 3% to 5% slope for the first 10 feet. If your foundation doesn’t meet this requirement, reach out to Venyscapes for a free estimate to make any any necessary landscaping adjustments. If that’s not possible, your options include:

• Crawl space encapsulation: Applying a tight seal to your crawl space to prevent moisture penetration.
• Applying a draining system: Digging a French or surface drain to draw water away from the house.

3. Installing Gutters and Downspouts

Putting in gutters and downspouts can prevent soil erosion and water damage to your foundation by moving water to a disposal area positioned at a safe distance away. Ideally, downspouts should be least five to 10 feet from the foundation walls, although exact distance will depend on the type and condition of the soil. A foundation repair contractor can advise you accordingly.

4. Adjust Your Landscaping

There are some landscaping and gardening measures you can take to prevent or minimize the risk of soil erosion. Plants can improve soil firmness by holding it in position with their roots, thereby preventing loss. Cultivate gardens and trees strategically around the property but with trees in particular, you’ll want to make sure that you don’t plant them too close to the foundation, as growing roots can cause damage.

5. Keep All Drainage Systems in Good Condition

Make sure that all of your drainage systems remain in good condition. If you have a gutter and downspout system, inspect them after a heavy downpour and remove any dirt and debris that could cause clogging. Do the same if you have drainage systems in place. You want to make sure that any water flows away from the area of the foundation so that erosion doesn’t have a chance to set in.
