The 100-Pound Problem and the 30-Pound Solution
In the early 20th century, construction relied on solid concrete blocks weighing more than 100 pounds each. They were difficult to lift, hard to transport, and cumbersome to stack. Builders needed a solution that would make construction faster, safer, and more efficient. The answer came in the form of the hollow concreate bricks (we often call them cinderblocks). By removing unnecessary material, Harmon S. Palmer created the foundation for what would become a mass-produced, uniform block weighing about 30 pounds. Lighter, easier to handle, structurally stronger, better insulated, and built to last, this new concrete block proved that removing what is not essential can create something more powerful and efficient.
