Our History

In June 2019, Reading Rock, Inc. and Columbus Coal & Lime Co./Granville Builders Supply combined resources to provide central Ohio with over 200 years of family owned and operated experience in the building materials industry by forming Reading Rock+CCL.

The Columbus Coal & Lime Co. was founded in 1888 by Carl Niermeyer who immigrated to the United States from Germany with his brother Fredrick at age 16. Carl, with the help of three other investors, became a business owner at the age of 40 and eventually bought out the other investors. As the name reflects, the company began selling coal and coke to residential and commercial customers as well as lime, cement, and brick.

The second generation took control in the 1920’s. After successfully taking the company through the depression expanded the product offering into plaster and finish lime for interior wall construction.

The company started selling more brick under the third generation in the 1940’s. With the construction of Interstate 70, Columbus Coal moved to its new location in Historic Franklinton. This location would not allow a permit for the storage and sale of coal, so the company continued to expand in masonry supply.

In 1972, the leadership of the company added construction-use chemicals, garage doors and tile. An additional location was added in Newark, OH operating under the name Granville Builders Supply.

Under the leadership of the fifth generation, Katherine Niermeyer Gatterdam and Rich Gatterdam, the company continued to provide masonry materials as well as concrete restoration chemicals and rebar fabrication to both the residential and commercial construction industries. These products and more will continue to be offered by the newly combined company of ReadingRock+CCL.

Reading Rock, Inc. founded in 1947 with its first block plant located in Reading, Ohio. Under its second generation of leadership, the company has expanded their products and services to include RockCast Architectural Stone, paving and retaining wall systems, brick, block & stone masonry veneers as well as hearth and tile offerings. With multiple locations in Ohio, Kentucky and Indiana, the company has local and regional distribution for its building materials and hardscape products while its RockCast brand is distributed nationally.

With a focused purpose and grounded by our ROCKS Core Values, it is more than just our products and services; it is our people that differentiate ReadingRock+CCL from other suppliers. From the plant floor to the job site, our top priorities are you and the products and services you choose. We are here to provide knowledge and service to ensure your next project is a success!
