About Mariswe


Mariswe (Pty) Ltd is a South African black-owned company which has been active throughout southern Africa since 1972. The company has a staff complement of more than 260 in 8 offices across South Africa. With a strong core of successful projects, the company has built a proud tradition of excellence in providing engineering solutions with integrity across sub-Saharan Africa. Mariswe takes this reputation forward with a focus on improving peoples’ lives in everything we do. 

In January 2019, following significant changes in ownership and the acquisition of three majority black-owned companies over a nine-year period, UWP Consulting changed its name to Mariswe to announce these changes to clients and the public.

Mariswe prides itself on the teamwork within and between its four self-sufficient regional operations spread across eight offices in South Africa. Our presence across provinces means we are particularly well-placed to service national, provincial and, most importantly, municipal government.

Roots in Africa

More than 35% of Mariswe’s revenue is currently generated outside South Africa and successful subsidiary firms have been formed in Tanzania, Zimbabwe, Botswana, Zambia and Ghana. Projects have also been completed recently in Liberia, Uganda, Lesotho, the Democratic Republic of Congo and Sierra Leone. A new branch of the South African business has recently opened in Lesotho.
