Buildex, Inc. is a Midwestern US producer of expanded shale lightweight agregate marketed as Buildex lightweight aggregate. The work Haydite in our logo refers to our roots that go back to Stephe J. Hayde, the inventor of expanded shale lightweight aggregate produced by the rotary kiln process.

The first Buildex plant was built in Ottawa, KS and began production in 1950. Since that time we have added plants at Marquette, KS and New Market, MO and boosted produciton capacity to over 750,000 cubic yards annually. Buildex expanded shale lightweight aggregate is our only product, allowing us to concentrate on quality, consistency, service and economy while serving a market area of 15 Midwestern and Rocky Mountain states.
