Asanduff Blocks Factory was founded in 1990 by John Gyarko Asante and his wife Hannah Dufie Asante (the Asan and Duff in our company name). The company initially focused on both blocks manufacturing and building construction. Today, Asanduff Blocks Factory focuses solely on manufacturing building blocks, ventilation blocks, walkway slabs, and landscaping stones while its sibling company, Asanduff Construction, handles the construction end of the business. With its decades-long history, Asanduff Blocks Factorys blocks can be found in landmark buildings and homes throughout the capitol city of Accra and other Ghana cities. The Asanduff Blocks Factory Difference: Innovation, Quality, and Service Asanduff Blocks Factory is committed to remaining on the leading edge of block production. Our modern factory is equipped with the latest technology and staffed by highly trained employees who genuinely care about every single block we make. Why? Because details matter as much to us as they do to you. This combination of technology, people, and attention to detail enables us to continue to produce high quality hollow and solid blocks without compromise.
