For professionals in the septic industry, understanding soil types is crucial for ensuring optimal drainage and preventing subsidence around homes. Efficient drainage relies on soil with large, loosely spaced particles, while dense soils can lead to water retention and potential problems. 

Sand

It’s your best bet for quick drainage. Its large, rough particles prevent clumping, allowing water to flow through effortlessly. This makes sand ideal for areas where rapid drainage is essential.

Silt

Silt offers decent drainage due to its relatively large particles, though it retains more moisture than sand. This makes silt a practical choice when some water retention is desired, such as for planting purposes.

Clay

Clay is the least effective for drainage. Its small, fine particles stick together tightly, creating tiny spaces that trap water and affect flow. This can lead to significant drainage issues and potential subsidence.

Most soils are a combination of these types, so selecting the right mix is key to maintaining effective drainage and preventing structural problems. For any drainage concerns or to address subsidence issues, professional guidance ensures your installations remain stable and efficient.
