Homeowners often wonder how to get clay soil to drain better. This is a vital topic, as soil issues can affect a home’s foundation, risking cracks and settling.

Clay soil can be quite challenging to work with. Clay tends to hold onto water and drain poorly. This risks premature foundation damage, as said. With this in mind, check out a few methods to use so you can get clay soil to drain better:
Incorporating organic matter like compost, well-rotted manure, or leaf mulch into the soil helps improve its structure and drainage. Organic matter creates pore spaces in the soil. These allow water to move more freely and prevents compaction. A landscaping engineer can help determine the best choice for your property’s soil.
First, avoid working with clay soil when it's too wet. Second, tilling or digging when it's slightly moist can help break up compacted layers and improve drainage. This also allows you to add organic matter mentioned above to those lower layers of the soil. You can also inspect it for needed drainage systems and other solutions.
If your property is consistently waterlogged, consider drainage systems like French drains, gravel-filled trenches, or perforated pipes. These systems help divert excess water away from problem areas. French drains are especially excellent for residential properties. A contractor buries these a few inches underground, so they’re out of sight and out of the way!
Adding coarse sand or grit to clay soil can improve drainage. It does so by increasing the size of soil particles and allowing water to flow more easily. However, avoid adding too much sand, as this can lead to a cement-like mixture. Again, discuss your property with a landscaping engineer if you need assistance with determining the right amount of sand or grit.
Apply a layer of organic mulch, such as wood chips or straw, to the soil surface. Mulch helps regulate soil temperature, reduce evaporation, and prevent compaction from heavy rain. Quality mulch also helps keep nutrients in the soil, for healthier vegetation and grass.
Using a core aerator or broad fork, create holes or channels in the soil. This helps to improve air circulation, water infiltration, and root penetration. The air will also help dry out the soil as needed. Aerating the soil also allows you to inspect it for needed underground irrigation and drainage.
