subbase Clause Samples
A subbase clause defines the requirements and specifications for the layer of material placed beneath a pavement or flooring system. This clause typically outlines the type of materials to be used, compaction standards, thickness, and preparation methods necessary to ensure a stable foundation. For example, it may require the use of crushed stone or gravel compacted to a certain density before the main surface is installed. The core function of this clause is to ensure the structural integrity and longevity of the finished surface by providing a properly prepared and supportive base layer.
subbase. One or more layers of specified material of designed thickness placed on the subgrade.
