What is the minimum base course thickness required?

The minimum base course thickness of 4 inches is established to ensure proper support and stability for the structure being built. This thickness is important because it helps to distribute loads evenly across the foundation and minimizes settling over time. A thicker base course can enhance the durability of the pavement or building floors above it.

In residential construction, having a solid and adequately thick base course is critical to preventing cracking and structural issues that can result from inadequate support. Furthermore, this thickness aligns with industry standards and codes designed to promote safety and longevity in construction practices. Additionally, achieving this minimum thickness can help ensure compliance with local building codes, which are designed to safeguard public health and safety.
