The History of Lemay Concrete Block

In 1947, Leonard Fred Detmer needed block for his own yard project. When they weren't available, he began making his own. From a single mold and hand crank mixer, Leonard made 8" x 8" x 16" standard masonry block. Once neighbors saw that he was making block, they inquired about buying theirs from him. It’s from those humbling days that Lemay Concrete Block was formed. Today, the family is still making those 8" x 8" x 16" masonry blocks but over the years, have added to their full line of masonry blocks, including ready-mix concrete, retaining walls, pavers, outdoor kitchen/backyard kits, and are still continuing to expand their product lines.

Doing a DIY shed with my dad. I wanted a slab so the shed would last. Lemay block was friendly from ordering, dispatch and the driver was on time and an experienced driver. The mix was good. And good price. First time finishing on my own but i think it went well.
