Graymont's Faulkner lime plant is located near Moosehorn, Manitoba, within two miles of the shore of Lake Manitoba. The plant consists of a preheater-equipped rotary kiln that can produce both high-calcium quicklime and dolomitic lime. The kiln is fired with pulverized coal and petcoke. Seven silos provide storage for pebbled, pulverized and crushed quicklime or dolomitic lime. The plant is fully equipped with truck load-out equipment. In addition to quicklime production, the plant produces calcium carbonate.

The demolition and dismantling of equipment at Graymont shuttered Pavilion plant was completed during 2018. The lime operations we indefinitely idled in 2016, due to a combination of poor market conditions, an uncompetitive cost structure and limited stone resources, and were permanently closed in late 2017.

Graymont's Summit lime plant is located in the Crowsnest Pass area of Southern Alberta. The plant produces limestone and aggregates. Lime operations at this site are currently idled.

The Exshaw plant, situated west of Calgary, Alberta, produces a wide range of lime and limestone products, including high-calcium quicklime, hydrated lime, pulverized limestone and screened limestone. Lime is produced in two rotary preheater kilns.

Storage and shipping facilities are designed to provide flexible load-out for both bulk truck and rail transportation of products, making this plant an extremely reliable source of supply. Bagged lime and limestone products are also available from this plant.
