Flat Roof & Slab Waterproofing in Centurion
Flat roofs and concrete slabs fail quietly — a hairline crack, a season of ponding water, and suddenly the ceiling below carries the evidence. SealPro manufactures the ArmTec HyperFlex reinforced waterproofing system for exactly these roofs, installed to specification by our approved local applicator. Centurion is estate country — Copperleaf, Southdowns, Blue Valley, Midstream — where roofs are newer but builder-grade coatings age fast under Highveld hail and UV, and every repaint must pass an HOA colour spec.

Why Centurion flat roofs and slabs leak
Centurion is estate country — Copperleaf, Southdowns, Blue Valley, Midstream — where roofs are newer but builder-grade coatings age fast under Highveld hail and UV, and every repaint must pass an HOA colour spec. Body-corporate slab and townhouse work runs year-round here. Concrete moves. Day-night temperature swings open hairline cracks, ponding water finds every one of them, parapet junctions separate, and old torch-on dries out and lifts at the laps. Patch products fail because they cannot move with the slab. Across Copperleaf, Southdowns, Blue Valley, Centurion Golf Estate, Midstream, Irene and Blair Atholl, the slabs that stay dry are the ones sealed as a continuous reinforced system.
The ArmTec HyperFlex slab system — step by step
Every product below is manufactured by SealPro Coatings and applied at factory-specified coverage rates — the same system, every roof.
- Inspection & moisture checkThe slab, falls, outlets and parapets assessed; trapped moisture and failed screed identified before any product goes down — overlaying a wet slab is wasted money.
- Repair & preparationCracks repaired, falls corrected where needed, and the surface primed with UltraBond WP so the membrane bonds to the slab, not to dust.
- ArmTec HyperFlex + mesh reinforcementThe ArmTec HyperFlex membrane applied with full ArmTec fibreglass mesh reinforcement — across the field of the roof, up parapets and into outlets, as one continuous seal.
- UV-stable topcoat / torch-on renewalFinished with UV-stable coats — and where an old torch-on exists, the torch-on alternative system renews it without stripping the roof open.

Centurion flat roof FAQs
Can you renew my old torch-on without ripping it off?
In most cases yes — if the membrane is still bonded, the ArmTec torch-on alternative system overlays and reinforces it. Quicker, cleaner, and the building stays sealed throughout.
The balcony above our living room leaks. Same system?
Yes — balconies and patio slabs get the same reinforced treatment, tied into door thresholds and railing posts, the two places patch jobs always miss.
Do you work to Centurion estate HOA specifications?
Yes — approved colour schemes, estate access procedures and trustee documentation are standard on our estate projects across Copperleaf, Southdowns, Midstream and surrounds.
