Waterproofing Contractors in Midrand

TDS Contractors carried out work on the PwC building in Midrand. Sitting between Johannesburg and Pretoria, Midrand is dominated by corporate office parks, warehousing and logistics facilities — large-footprint buildings where roof area is measured in thousands of square metres and a leak interrupts a working business.

What Midrand does to a building

Large-format commercial and industrial roofs behave differently from domestic ones. Long unbroken spans accumulate significant thermal movement across their length, which concentrates stress at upstands, expansion joints and penetrations. Drainage design matters more as roof area grows, because ponding water — standing on a low-fall roof after a Highveld storm — is one of the most reliable ways to shorten a membrane's life. Warehouse and distribution facilities also carry a real business cost to any leak: stock damage and operational downtime usually dwarf the cost of the waterproofing itself.
