About Us


A history of quality concrete products and services

Gillett Cement Products was started in 1947 by Wesley Peterson as a block plant. Shawano Concrete Products, located in the Shawano Industrial Park, was started in 1984 by Curt and Irene Streblow. In October of 1998, CNI Companies Inc. was formed with plants in Gillett, Shawano, Marinette, and Pound. In 2002 Middle Inlet Concrete Products was added allowing the company to serve customers in northern Marinette County. In 2005, all plants were purchased by Verrette Materials Inc. which is based out of Iron Mountain Michigan. All the plants in the Verrette family of companies sell block, ready-mix concrete, related building materials along with sand and gravel.

Seven decades of customer-focused solutions

In addition to our comprehensive equipment and product line, we bring over 60 years of industry experience to find solutions in meeting customer project requirements. Our staff of technical experts regularly works with architects and engineers to assist in writing concrete mix designs and aggregate specifications to meet state and local approval. We are always looking for innovations and products to enhance quality and efficiency. To help educate customers, we conduct technical and new product workshops. This focus on helping our customers increase profitability has led to many of our customers remaining with us for over 30 years.
