What is the best type of material to set a house foundation on?

The best type of material to set a house foundation on is gravel. Gravel provides a strong, stable base that allows for effective drainage, which helps prevent water accumulation around the foundation. A foundation built on gravel is less likely to experience issues related to shifting or settling, as gravel does not retain water like clay or loam, which can expand when wet and contract when dry. Additionally, gravel allows for some flexibility due to its coarse composition, which helps in distributing the load from the structure evenly.

In construction practices, a solid foundation is crucial for the longevity and structural integrity of a building. Using gravel mitigates risks associated with soil saturation and shifting ground, which can lead to foundation damage over time. The characteristics of gravel make it an ideal choice in various types of soil conditions, providing a reliable support system for residential structures.
