A waterproofing sinking fund, more formally called a reserve fund, is a dedicated pot of money set aside specifically to pay for major future repairs and maintenance on a property scheme. Think of it as a collective savings account for the building itself. Rather than scrambling for cash when the roof starts leaking or damp begins creeping through a basement wall, the money is already there. For sectional title owners in South Africa, this is not optional. The Sectional Titles Schemes Management Act (STSMA) requires every body corporate to establish and maintain a reserve fund separate from its day-to-day administrative fund.
The types of repairs this fund covers include:
- Roof waterproofing and replacement
- Damp proofing and structural waterproofing
- External painting and facade repairs
- Boundary walls, paving, and driveways
- Lifts, pumps, and major mechanical systems
The core purpose is straightforward: spread the cost of expensive, predictable repairs over many years, so no single owner faces a sudden, large special levy.
How are contributions to the reserve fund calculated?
The contribution rules under the STSMA are tied directly to the fund’s balance relative to the annual administrative budget. The thresholds work like this:
- Below 25% of the admin budget: the body corporate must contribute at least 15% of the coming year’s administrative fund budget to the reserve fund.
- Between 25% and 100%: contributions must equal at least the amount budgeted for repairs and maintenance in the coming year.
- At or above 100%: no minimum contribution is legally required.
In practice, most schemes start well below the 25% threshold, so owners can expect levy increases of at least 15% annually in the early years while the fund builds up. That is not a penalty; it is the fund doing exactly what it is designed to do.
The 10-year maintenance, repair and replacement plan (MRRP) sits at the heart of this calculation. Trustees use it to project every major capital expense over a decade, from roof waterproofing to lift overhauls, and set contribution levels accordingly. Without an MRRP, contribution figures are essentially guesswork.
Pro Tip: Request a copy of your scheme’s current MRRP before you buy into any sectional title development. A well-prepared plan tells you far more about the building’s financial health than the sales brochure ever will.
What can the sinking fund actually be spent on?
The reserve fund and the administrative fund are legally distinct, and the line between them matters. The administrative fund covers running costs: security, gardening, water, electricity, and management fees. The reserve fund covers major capital maintenance only.
Permissible reserve fund expenditure includes:
- Roof waterproofing and structural waterproofing works
- Exterior repainting
- Replacement of lifts, pumps, and access control systems
- Driveway resurfacing and paving
- Water reticulation and plumbing infrastructure
Using reserve funds to pay a gardening contractor or cover a security guard’s wages is not permitted. Trustees who misuse the fund expose themselves to legal liability. The distinction protects owners: it guarantees that the money collected for waterproofing repairs is still there when the waterproofing repairs are actually needed.
Planned expenditure drawn from the MRRP also removes the need for emergency special levies. When a roof membrane fails after 15 years, a well-funded scheme simply authorises the work. A scheme with an empty reserve fund charges every owner a lump sum, often at short notice.
What does South African law require?
The STSMA, which came into operation on 7 October 2016, made the reserve fund compulsory for all sectional title schemes. Section 3(1)(b) places a direct duty on the body corporate to establish and maintain the fund. Key legal requirements include:
- The reserve fund must be held in a separate, interest-bearing account, entirely apart from the administrative fund.
- A 10-year MRRP is a legally mandatory document that justifies spending decisions and contribution levels.
- Minimum contribution thresholds are set by regulation, not by trustee discretion.
- Misuse of reserve funds can result in legal challenges and personal liability for trustees.
The shift from ad hoc special levies to a planned reserve fund system represents a fundamental change in how South African property schemes manage their finances. Property managers note that this approach reduces financial shock for owners and supports steady, predictable upkeep of common property. Banks and buyers scrutinise reserve fund health when assessing a scheme, and a thin or absent fund can affect both the marketability of units and the availability of financing.
Any prospective buyer should request the body corporate’s financial statements, including the reserve fund balance and the MRRP, before signing an offer to purchase.
Why a dedicated waterproofing fund protects your property
Water damage is one of the most destructive and expensive problems a building can face. A leaking roof or failed waterproofing membrane does not stay contained; it migrates into structural elements, causes mould, and can render units uninhabitable. The cost of reactive repairs is consistently higher than the cost of planned maintenance, because by the time visible damage appears, the underlying problem has usually been developing for years.
A properly funded reserve account changes that dynamic entirely. Benefits specific to waterproofing include:
- Prevention of water ingress before structural damage occurs
- Preservation of the building envelope and long-term asset value
- Avoidance of emergency special levies that can run to tens of thousands of rands per unit
- Legal compliance, protecting trustees and owners alike
Professional building condition assessments are the foundation of an accurate MRRP. Trustees who rely on informal estimates risk underbudgeting for waterproofing and structural repairs, leaving the fund short precisely when it is needed most. A qualified assessor will identify the remaining service life of roof membranes, identify early-stage damp penetration, and cost replacement works realistically.
Regular audits of the reserve fund, transparent reporting to owners at annual general meetings, and a current MRRP are the three practices that separate well-run schemes from those that lurch from one crisis to the next.

A well-funded waterproofing sinking fund, backed by a current 10-year MRRP, is the single most effective way to protect a sectional title scheme from costly emergency repairs and sudden special levies.
