Subbase

A subbase is a layer of granular material placed above the natural or engineered subgrade and below the base course in a pavement or slab section, used to add structural capacity, improve drainage, and provide a stable working platform, especially over weaker subgrade soils.

Compiled by the Reborn Rental team, backed by our field engineers and dispatch staff working Denver-metro concrete washout and equipment rental jobs.
