- Commercial waterproofing. Flat roofs, plant rooms and podiums on offices and apartment blocks.
- Basement waterproofing. Parkades and basements with seepage through walls, slabs and joints.
- Joint sealing. Movement joints on podiums, parking decks and facades.
- Balcony waterproofing. Apartment balconies leaking into units below.
- Concrete roof waterproofing. Concrete slabs with cracks over offices and top-floor units.
Podiums, Roof Terraces and Parkades
- Podium decks. Gardens, paving and planters over parking need a membrane, protection and drainage below the finish.
- Roof terraces. Water often gets in at door thresholds, planter edges and balustrade fixings.
- Parkades. Seepage through joints and cracks leaves stains, rust on rebar and drips on cars.
Leaks on these areas usually show far from where water enters, so leak tracing comes before any quote.

Get Waterproofing QuotesWhat Affects the Quote
- Finishes on top. Paving, soil or tiles over a membrane must be lifted and replaced.
- Access and height. Cranes, scaffolding or rope access add cost on taller buildings.
- Working hours. After-hours or weekend work for occupied offices costs more.
- Specification. A consultant's specification sets the system and may require approved applicators.
- Phasing. Doing a roof or podium in sections keeps parking and units usable but adds set-up costs.
Weather and Scheduling
Highveld storms in summer drive water into podium drains and roof outlets at high volume. Plan large jobs for dry months and ask for outlet clearing and temporary sealing before the rains.
Working in Occupied Buildings
- Safety file. Larger buildings usually require a health and safety file before work starts.
- Hot works. Torch-on needs a hot works permit and fire precautions on many sites.
- Tenants. Agree access times, noise and parking closures with the managing agent.
Questions to Ask
- How will you trace where the water enters?
- Which system suits a trafficked or planted podium?
- Who removes and reinstates paving, soil or tiles?
- What guarantee is offered and by whom?
- Can the work be phased around tenants and parking?
Waterproofing Illovo FAQs
Why does the parkade leak when the podium above looks fine?
The membrane under the paving or soil may have failed, or water may be getting in at joints and drains. The finish on top hides the damage.
Can a podium be waterproofed without lifting everything?
Sometimes joints and drains can be repaired locally. A failed membrane over a large area usually means lifting the finishes.
Do I need an engineer or consultant?
For large podiums, parkades or structural cracks, a consultant's assessment and specification is common and helps line up quotes.
What does commercial roof waterproofing cost?
Ballpark R180 to R450 per m², plus access, preparation and any finishes that must be lifted.
