The American Midwest came into its own during early 1900s - and much of it was built using gray construction blocks from Anchor Block Company. Back then, Anchor had 10 sizes and one color to choose from. Selection wasn't a priority, but dependability and longevity were. Which is why Anchor gray blocks became the backbone of Midwest construction and infrastructure. During this time, Anchor earned its reputation as the gold standard for reliability, durability and consistency in construction materials. Today, our catalog of products, textures and colors has grown tenfold. But more importantly, our reputation for quality remains fully intact - like many of the gray blocks we made over 90 years ago. It's the biggest reason homeowners, contractors and builders looking for construction materials still look to Anchor Block.
