PwC Tower, Midrand
Project context
The PwC Tower anchors the Waterfall City development in Midrand as the practice's South African headquarters. Its distinctive twisting form makes it one of the most recognisable commercial buildings on the Johannesburg–Pretoria corridor.
Why this building is difficult to waterproof
Geometrically complex buildings are considerably harder to waterproof than their rectilinear neighbours. A twisting façade produces junctions that are not repeatable — each level meets the envelope at a slightly different angle, so details cannot simply be replicated floor to floor and each condition requires its own resolution. Complex forms also concentrate and redirect water in ways simple elevations do not, loading particular junctions far more heavily than a uniform design assumption would predict. On a corporate headquarters the tolerance for visible defects is low: staining, efflorescence or damp on a flagship building is a reputational matter for the occupier as much as a technical one.
