PHASE_01
When torch-on is the right tool
Torch-on fits big, open concrete decks when hot works, wind limits, and insurers align.
Torch-on & liquid applied membrane systems
There is no universal “best” membrane, only the right system for geometry, fire constraints, substrate condition, and maintenance access. Maverick specifies torch-on, liquid polyurethane, acrylic, or hybrid programmes after moisture risk assessment, adhesion testing, and manufacturer exposure tables, so guarantees remain enforceable after handover.
Torch-on fits big, open concrete decks when hot works, wind limits, and insurers align. Seams, corner reinforcement, and protection sheets follow datasheets, no improvised laps or shortcut primers that void the guarantee.
Liquids follow complex shapes, plant bases, and penetrations without seam grids vulnerable to holidays. Primers, fleeces, and UV topcoats are sequenced with dew-point and moisture discipline before each coat closes.
Many sites torch field areas and detail in liquid at HVAC clusters, parapets, and outlets. Interfaces between systems are documented so a warranty claim cannot die at the trade boundary nobody planned for.

Our waterproofing approach
Diagnostics first. Detailing discipline. Co-signed guarantees.
PHASE_02
When liquid systems win
Liquids follow complex shapes, plant bases, and penetrations without seam grids vulnerable to holidays.
PHASE_03
Hybrid programmes are common

Fire constraints & alternative specifications
Retail podiums and insured assets sometimes ban open flame.
Waterproofing Philosophy
Why membrane renewals belong in your portfolio risk plan
Phase 01 / Assessment
Torch-to-liquid conversion
Core samples showed inter-laminary moisture in an aged torch-on deck; phased drying and a liquid overlay avoided trapping vapour under a repeat torch layer.

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.
Flat concrete roof waterproofing
Torch-on vs liquid trade-offs, drainage and ponding risk, UV protection, hybrid programmes, and manufacturer-backed maintenance calendars.
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.
Phase 02 / Execution
Insurance-driven flame restrictions
A retail podium required full liquid specification after insurer declined hot works; detailing at drains matched manufacturer-approved liquid details.

Retail podiums and insured assets sometimes ban open flame. We switch to full liquid or cold-applied stacks with insurer-ready method statements, fire watches where still required, and penetration details that match listing letters.

Phase 03 / Handover
Hybrid office roof
Field areas used torch-on for speed while plant bases received liquid flashings, reducing programme risk without compromising critical interfaces.

Frequently asked questions
Technical answers for procurement teams, trustees, and facility managers in Gauteng.
Is torch-on still used in Gauteng?
Yes where permits, wind, and substrate conditions allow. Maverick selects systems based on risk registers, not product preference.
Can liquid membranes go over torch-on?
Sometimes, after adhesion and moisture testing. Not every aged torch-on deck is a suitable substrate.
What about fire risk?
Hot works controls, fire watches, and insurer approvals are planned. Liquid systems are specified when flame work is prohibited.
Do you issue QA reports?
Independent QA can be bundled for portfolio managers requiring third-party sign-off on film build and holiday testing.
How do I compare quotes?
Compare system type, removal scope, detailing standards, and warranty maintenance obligations, not m² bait pricing alone.
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.
- 02
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.
