Base Course | 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.
There are two categories of based course. Dense graded Bases, referred to locally as traffic bond, are well graded and include fines that firm up and become a hard, solid base for a variety of uses in construction. In general, the heavier the load, the larger the stone you will select in your base course.

Open graded base is a uniformly graded mixture of stone with the finer particles removed. This is done to provide drainage through the base. Halquist produces open graded based to WisDOT specifications for new road construction. Many of our clear stones can also be used in many other applications where drainage through the aggregate is necessary.
