PHASE_01
Positive vs negative side interventions
External positive barriers suit new construction; negative remedial tanking applies when bulkheads cannot be dug out.
Basement tanking & underground waterproofing
Hydrostatic pressure finds the weakest detail: construction joints, kicker joints, pipe penetrations, and honeycombed lifts. Maverick executes tanking as a system, not a single brush coat, sequencing surface preparation, active leak management, membrane or crystalline courses, and protection screeds exactly as the engineer and manufacturer define.
External positive barriers suit new construction; negative remedial tanking applies when bulkheads cannot be dug out. We state limitations honestly, negative builds manage hydrostatic load differently and must follow engineer design.
Where specified, crystalline systems (such as Xypex-type formulations) penetrate concrete capillary tracts and react with moisture and cement hydration by-products to form non-soluble crystalline structures, rendering the concrete mass impermeable to water and aggressive groundwater chemicals.
These technologies can resist extreme hydrostatic pressure from positive or negative sides and possess self-healing properties for future hairline cracks up to approximately 0.4 mm, often specified for lift pits, elevator shafts, and underground parking grids.

Our waterproofing approach
Diagnostics first. Detailing discipline. Co-signed guarantees.
PHASE_02
Crystalline waterproofing technology
Where specified, crystalline systems (such as Xypex-type formulations) penetrate concrete capillary tracts and react with moisture and cement.
PHASE_03
Active leak management before skin coats
Fast leaks need grout, injection, or relief drainage before membranes see constant head.
PHASE_04
Lift pits, plant rooms, and parking slabs
Oil interceptors, brine decks, and sprinkler testing change chemical risk for each space.

Phase 01 / Assessment
Midrand office basement retrofit
Crystalline and cementitious layering combined with sump redundancy stopped recurring lift pit flooding after failed DIY coatings.

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.
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

Vapour management and drainage boards were sequenced before specialist AV contractors entered.

Oil interceptors, brine decks, and sprinkler testing change chemical risk for each space. Facility inputs go into a short risk register so specification matches how those rooms are actually used and cleaned.

Phase 03 / Handover
Hospital plant room negative-side intervention
Night-only working and low-odour systems met infection-control constraints while maintaining emergency plant access.
Fast leaks need grout, injection, or relief drainage before membranes see constant head. Skipping active-water control is the usual reason a tanking file fails in the first wet season after handover.
Oil interceptors, brine decks, and sprinkler testing change chemical risk for each space. Facility inputs go into a short risk register so specification matches how those rooms are actually used and cleaned.
Membranes need sacrificial screeds, careful backfilling, and sump checks where designed. Handover includes what to watch after occupancy, sump run hours, alarm tests, and who to call before a small leak becomes a lift shutdown.

Frequently asked questions
Technical answers for procurement teams, trustees, and facility managers in Gauteng.
Can you tank from the inside only?
Often remedial projects must. Feasibility depends on wall construction, water load, and engineer design, Maverick implements specified systems.
What about crystalline admixtures?
Used where specified for new concrete or remedial systems. Not a universal fix for active defect networks alone.
Will tanking stop rising groundwater completely?
Engineered systems manage risk to defined performance criteria. Absolute guarantees are avoided; maintenance and drainage matter.
Do you excavate externally?
Where programmes and neighbours allow, positive-side work may be advised, each site differs.
How do you protect new membranes during backfill?
Protection boards, sacrificial screeds, and sequencing notes are part of QA packs.
What testing is done?
Flood or hose testing may be specified post-cure; holiday detection applies to sheet systems.
Our Unbeatable Guarantee
De-Risking Your Multi-Million Rand Asset.
