- Rooftop plant. Air-conditioning, ducting and services penetrating the membrane, with detailing around each one carrying the risk.
- Body corporate and precinct rules. Managed buildings with approval processes and set working hours.
- Balconies over units. Failed membranes showing in the flat below, which makes it a scheme matter immediately.
- Concealed drainage. Internal outlets that discharge inside the building when they block.
- Wind exposure on open ground. Membrane edges and terminations under sustained load.
- Commercial and residential mixed. Different access constraints on the same roof structure.
What Is Built Here
A planned mixed-use precinct of apartment blocks, offices and retail, almost entirely concrete flat roofs with parapets, rooftop plant and extensive balconies.
In a managed precinct, the approval and scheduling process usually takes longer than the work. Getting the survey and specification agreed early is what keeps a project on its intended timeline.

Frequently Asked Questions
How is roof work approved in a managed precinct?
Through the body corporate or managing agent, often with precinct-level rules on working hours, access and contractor registration on top of the scheme's own.
What causes leaks around rooftop air-conditioning?
Each unit, duct and cable tray is a penetration through the membrane. Collars perish, plinths crack, and services added later are often installed without the membrane being made good.
Is the cheapest waterproofing quote usually the right one?
Rarely. The cheapest quote is typically the one that coats over the existing membrane, prices preparation as a variation and excludes making good. Compare the inclusions before comparing the totals.
How much does waterproofing cost in Century City?
Roof waterproofing generally runs R150 to R350 per square metre, with torch-on membrane at R300 to R400. A 40 m² flat roof typically lands between R12,000 and R24,000. Damp treatment on a single wall usually totals R6,000 to R18,000.
How do I compare waterproofing quotes for a property in Century City?
Compare the specification rather than the total. Which system, how many coats or layers, what preparation is included, how upstands and outlets are detailed, and what the guarantee excludes. Two quotes far apart usually differ on stripping and preparation.
When is the best time of year to book waterproofing in Century City?
Late summer or autumn. Membranes and coatings need a dry substrate and a dry curing window, and contractors fill up as soon as the first winter fronts arrive.
