Subgrade

Subgrade refers to the layer of soil that lies beneath a road, pavement, or hardscape project. The subgrade provides foundational support and must be properly compacted and leveled to ensure the stability of the surface above. A well-prepared subgrade is crucial to prevent cracking, settling, or shifting in the finished project. The strength and composition of the subgrade affect the longevity and performance of paved surfaces and other hardscape installations.
