Clear Stone | Aggregates

Halquist Stone is Wisconsin's leading producer of construction aggregates. We produce these materials from natural limestone deposits. Our quarrying process typically begins with drilling and blasting the rock into smaller pieces. Next, the material goes through various stages of crushing and screening to produce the sizes and specifications desired by our customers.

Aggregates are sized into one of two categories: clear stone (no fines) or base course (with fines). Clear stones are various sizes of aggregate with the fine material either screened or washed out of the product. Among other properties clear stone allows drainage through the material. Specifically, Clear Stone is produced by screening out/or washing out fine materials. Below you will find our standard inventoried sizes. Additionally, we frequently manufacture custom blends to meet specific needs of a given project.
