Diagnose damp, seal roofs and balconies, repair showers, and choose systems that suit your climate.
Identify possible efflorescence, distinguish clay from concrete paving, trace recurring moisture and choose a cautious next step before cleaning or sealing in South Africa.
Read the guide →A durable shower starts with a stable substrate, correct falls, reinforced corners, and a complete compatible membrane system.
Read the guide →Compare height, shape, timing, location and weather patterns before paying for a treatment that may solve the wrong problem.
Read the guide →Sometimes—but only after proving the old tiled assembly is stable and resolving falls, drainage, thresholds and edge details.
Read the guide →Plan balcony waterproofing around drainage, falls, junctions, a compatible membrane system and a protected finish—before tiles conceal the work.
Read the guide →Waterproofing succeeds when the water source, route and exit are understood before a product is chosen. Start with drainage and detailing, then match a complete system to the surface and exposure.
Separate rain entry, plumbing leaks, condensation and ground moisture. Similar stains can need completely different repairs.
Corners, outlets, penetrations, thresholds and changes of material usually fail before the broad flat area.
Primer, membrane, reinforcement, adhesive and sealant should be compatible and installed to the maker’s full specification.
In South Africa, Australia and New Zealand, exposure can range from intense UV and wind-driven rain to coastal salt, frost and humid subtropical conditions. Specify the system for the exact surface, water pressure, movement and climate; a product approved for an internal shower is not automatically suitable for a balcony, basement or exposed roof.
Record when water appears, weather conditions, plumbing use and the highest damp evidence. Ask each contractor to identify the source and path, not merely name a coating.
Draw drains, thresholds, corners, penetrations, upstands and movement joints. These small areas control the performance of the broad membrane.
Retain substrate checks, batch numbers, coverage calculations, coat times, photographs, tests, certificates and maintenance requirements before finishes conceal the work.
Only after the source, trapped moisture and failed detailing are corrected. Coating over an active defect often hides it temporarily.
Service life depends on exposure, movement, drainage, preparation and the complete system. Inspect exposed details and sealants regularly.
Water-resistant materials tolerate limited moisture exposure; waterproof systems prevent water passage under their specified conditions. Local codes define where each performance level is required.
Where permitted or required, a controlled test can reveal defects before finishes are installed. The test method, duration, drainage isolation and structural limits must be agreed by the responsible professional.
