About Us

Stumbelbloc is a revolutionary interlocking concrete building block, designed and manufactured in Zimbabwe to make building faster, stronger, cheaper and easier than conventional brick-and-mortar construction.

Because every block is identical and interlocks precisely with the next, walls go up straight and square with only limited training. There are no mortar beds to level, and the built-in cavities carry electrical and plumbing services and keep homes naturally cooler.

From individual homeowners building their first house to contractors putting up warehouses, schools and boundary walls, Stumbelbloc lets you do more with less cement, less labour and less time.
