PHASE_01
Torch-on vs liquid, honest trade-offs
Torch-on suits large open decks when permits, wind, and insurance allow; liquids suit complex geometry and penetrations where seams are risky.
Flat concrete roof waterproofing specialists
Flat roofs fail at interfaces: outlets, plant bases, expansion strips, and perimeter kerbs. Maverick specifies torch-on or liquid-applied systems based on geometry, occupancy fire risk, UV exposure, and maintenance access, then executes preparation, detailing, and protection courses to manufacturer standards so guarantees remain enforceable.
Torch-on suits large open decks when permits, wind, and insurance allow; liquids suit complex geometry and penetrations where seams are risky. We choose from risk registers and test data, not a favourite brand in the yard.
Permanent ponding ages any membrane faster. If falls are wrong, we flag re-screed or levelling scopes instead of burying the hydraulic problem, SANS narratives go into the report so trustees understand combined budgets.
Moisture readings, primer compatibility, corner reinforcement, and sequential holiday tests matter more than adjectives. Independent QA bundles are available for portfolios that want third-party sign-off on the full stack.

Our waterproofing approach
Diagnostics first. Detailing discipline. Co-signed guarantees.
PHASE_02
Drainage, falls, and long-term ponding risk
Permanent ponding ages any membrane faster.
PHASE_03
QA checkpoints that protect warranties
Moisture readings, primer compatibility, corner reinforcement, and sequential holiday tests matter more than adjectives.
PHASE_04
Protection courses & long-term maintenance
Manufacturer guarantees on torch-on systems (such as 3–4 mm dual-reinforced polyester polymer-modified bitumen membranes) typically require.
Waterproofing Philosophy
Why membrane renewals belong in your portfolio risk plan
Phase 01 / Assessment
Failed torch-on overlay with trapped moisture
A liquid system was specified after core samples showed inter-laminary moisture; phased drying and venting avoided blistering the new membrane.

Dedicated waterproofing service pages
Thin, catch-all waterproofing pages dilute intent for high-value queries like flat slab renewals, under-tile balconies, and basement tanking. Maverick’s spoke pages unpack methodology, compliance context, and BC documentation separately.
Leaking balcony remediation
Sectional-title documentation, low-disruption options, exclusive-use interfaces, and coordination with structural arris repairs.
Basement tanking & sub-structure waterproofing
Negative- vs positive-side logic, active leak management, lift pits, and parking slabs with hydrostatic pressure risk.
Torch-on & liquid applied membranes
System selection, hybrid programmes, fire constraints, and manufacturer-backed detailing for torch-on and liquid membrane stacks.
Phase 02 / Execution
Office park HVAC cluster
Complex plant bases received liquid detailing while field areas used torch-on for speed, hybrid programmes are common when fire and geometry conflict.

Manufacturer guarantees on torch-on systems (such as 3–4 mm dual-reinforced polyester polymer-modified bitumen membranes) typically require bi-annual maintenance and UV-reflective aluminium or elastic acrylic topcoats to prevent polymer embrittlement from constant Highveld solar radiation.

Sectional-title top storey leaks
Trustee packs included photographic condition logs, outlet rebuilds, and 10-year manufacturer maintenance calendars.

Handover includes maintenance calendars and photo logs so facility teams know what “good” looks like five years after completion.

Frequently asked questions
Technical answers for procurement teams, trustees, and facility managers in Gauteng.
Why do Gauteng flat roofs leak so often?
UV embrittlement, ponding, detailing errors at penetrations, and foot traffic without protection courses are frequent contributors. Combination failures are normal.
Can you waterproof over an old torch-on?
Sometimes, after adhesion tests and moisture risk assessment. Not every aged system is a suitable substrate, engineer/manufacturer guidance decides.
How long before rain exposure after liquid application?
Product-specific. We track weather windows and may tent critical stages during Highveld thunderstorms.
Do you issue maintenance plans?
Manufacturer-backed warranties typically require periodic inspections and debris clearing, we document those obligations plainly.
What about rooftop safety?
Harness lines, edge protection, and rescue plans are filed for rope or perimeter work per OHS requirements.
Is ponding acceptable?
Temporary ponding after storms differs from chronic structural ponding. Chronic cases need drainage remediation, not only membrane replacement.
Our Unbeatable Guarantee
De-Risking Your Multi-Million Rand Asset.
Unlike standard contractors who rely on biased, in-house quality checks, we use a trusted, independent third-party QA company on all projects. This is our commitment to verifiably superior quality.
- 01
Substrate Specification & Assessment
A dedicated project manager and the independent body conduct an on-site assessment to determine the correct coating system and technical specification required for your specific asset.

Continuous Application Inspection
The independent company performs continuous application inspections at every critical stage (surface prep, primer, film thickness) to ensure manufacturer requirements are met before the final coat.
- 03
Verifiable Bi-Weekly Reporting
You receive bi-weekly progress and substrate reports providing a complete, recorded history of the project. This delivers objective proof of quality and total peace of mind for trustees and facility managers.
