Geology

The Lisbon Pit is somewhat unique in that it contains a gravel pit and a dolomitic limestone quarry in one location. The site is primarily covered by a glacial till containing many large rocks and boulders. This predominance of large rock gives our stone products a very high percentage of fractured faces resulting in a better performing aggregate for concrete, asphalt, and backfill applications. Under the glacial till is a hard white/grey dolomitic limestone deposit. Like our Lannon Quarry this deposit contain 3 basic layers:
      1. Building stone layer – containing large, continuous layers of varying thickness ideal for use in architectural and building stone applications.
      2. Chert free limestone layer – the thickest layer in the Sussex quarry is comprised of a hard, chert-free limestone ideal for use in high-strength concrete, rip-rap or erosion control, and general construction.
      3. Standard limestone layer – the bottom layer in our Sussex quarry is more typical of the limestones in SE Wisconsin and is used for road base, clear stone, and general construction.
