Liquid waterproofing is often discussed as though it were one technology. In practice, the product only becomes a system when its chemistry, substrate requirements, reinforcement, details, exposure and—below ground—the direction of hydrostatic pressure are considered together.
Exposed liquid membranes.
Six products form the core roof, balcony and trafficked-floor selection. Their most important difference is not colour or packaging—it is the condition and use in which each product is expected to perform.
WINKLER ONE®
Damp or wet substrates · 0°C to +45°CThe main choice where residual moisture, uncertain drying conditions or a wider application-temperature window make conventional water-based systems difficult to use.
ONE® VERTICAL
Vertical details · damp or wet substratesA thixotropic version developed for vertical applications, complex profiles and details where stability on the surface is as important as waterproofing continuity.
WINGUM PLUS® H₂O RAPID
Prepared dry substrates · +5°C to +35°CA fibre-reinforced system for roofs and larger areas where fast rain resistance is important, but substrate moisture and application conditions remain tightly controlled.
2021
Prepared dry substrates · exposed finishA water-based, UV-resistant liquid membrane used where a smooth continuous finish is required over a correctly prepared and dry substrate.
2021 FIBER
Prepared dry substrates · distributed reinforcementThe fibre-reinforced development of 2021, providing reinforcement throughout the coating for substrates exposed to stress or vibration.
ONE® FLOORING
Damp or wet substrates · vehicle + industrial trafficA coloured, UV-resistant ONE-system membrane for waterproofing and protecting concrete, tiled and mechanically sound asphalt floors exposed to vehicle or industrial traffic. Joints and movement still require a dedicated detail strategy.
Do not select by habit.
| System | Substrate starting point | Primary role | Key limitation to check |
|---|---|---|---|
| ONE® | Damp, very humid or wet | Exposed high-performance waterproofing | Substrate strength, contamination and detail design |
| ONE® VERTICAL | Damp or wet vertical surfaces | Vertical and complex-profile waterproofing | Not a substitute for correct void and joint repair |
| H₂O RAPID | Prepared dry surface | Fast rain-resistant roof membrane | Moisture, weather window and reinforcement requirements |
| 2021 | Prepared dry surface | Smooth exposed elastomeric membrane | Hidden moisture and correct film build |
| 2021 FIBER | Prepared dry surface | Fibre-reinforced exposed membrane | Fibres do not remove the need to resolve joints |
| ONE® FLOORING | Damp, very humid or wet floor substrate | Waterproofing + drive-over wearing protection | Substrate strength, joints, contamination and traffic demand |
Waterproofing, protection and treatment are not the same.
These products sit beside the core membranes but perform different jobs in the wider building-envelope strategy.
WINGRIP® BITUMINOSO
Waterproofing + adhesion-promoting layerA single-component polymer-bitumen membrane used beneath tiled finishes on terraces, balconies, bathrooms and shower areas. It is part of the covered build-up—not an exposed roof finish.
Official product page ↗WIN BITUROOF
Levelling + slope-restoration pasteA ready-to-use bituminous paste for levelling aged bituminous membranes, restoring local falls and forming horizontal-to-vertical connection shells before the new waterproofing layer. It is a preparation product—not the final membrane.
Official product page ↗ECOIMPRIMER
Water-based anti-dust + adhesion treatmentA professional bituminous primer used to control dust and promote adhesion before laying heat-applied bitumen-polymer membranes. It is not a universal primer for every liquid waterproofing system.
Official product page ↗2000 PLUS
Protective coating for aged bituminous membranesAn elastomeric protective coating for existing oxidised bituminous membranes. Its role is protection and service-life extension; substrate age and preparation remain critical.
Official product page ↗ECOSILVERALL
Water-based aluminium coatingA flexible aluminium protective coating for bituminous coverings. It provides a bright protective finish but should not be confused with the primary waterproofing membrane beneath it.
Official product page ↗SKERMO TERRAZZE
Deep-penetrating, non-film-forming protectionA transparent treatment for tiled balconies and terraces that penetrates through grout lines without changing the appearance. It does not replace movement-joint repair or bridge active cracks.
Official product page ↗Which side of the water pressure?
External and internal basement waterproofing solve the problem from opposite faces of the structure. They are not interchangeable routes.
Stop water before it enters the structure.
Accessible external face · foundations + earth-retaining wallsA high-build, trowel- or spray-applied waterproofing system made with highly elastic resins and puncture-resistant additives. It is used on counter-ground walls, foundations and concrete structures, including vapour-barrier layers below foundation build-ups, subject to the approved substrate and detail design.
Control water from the accessible internal face.
External face inaccessible · basements + underground roomsThe internal route must resist water pressure acting through the structure. Active ingress, damaged backgrounds and damp substrates are treated as separate conditions using BLOCKWATER, WINPLASTER and/or WINFIX WET in a project-specific sequence.
The membrane is installed on the water-entry side, helping prevent the structure from becoming saturated.
The treatment must remain bonded while water pressure acts through the wall or slab from behind.
Stop, rebuild, then select the control layer.
An active leak, a damaged wall, counter-pressure moisture and a damp substrate are four different conditions. The project build-up may use some—not automatically all—of these materials.
BLOCKWATER
Ultra-rapid cement mortar for stopping local active water ingress, including leakage under pressure. It resolves the active point before the wider waterproofing build-up is completed.
Official product page ↗WINPLASTER
A single-component waterproof, fibre-reinforced plaster for forming thicker waterproof baseboards and treating concrete or plaster walls in layers up to 20–30 mm.
Official product page ↗WINPOX CEMENT TIXO
A three-component thixotropic epoxy-cement mortar for humid surfaces affected by counter-pressure moisture. It can waterproof underground rooms, lift pits, floors and concrete pools while providing a vapour-barrier or resin-system base where specified.
Official product page ↗WINFIX WET
A two-component thixotropic epoxy-cement system formulated to cure on moist cementitious substrates. It creates a controlled base for subsequent resin finishes on underground rooms, lift pits, pools and floors where substrate moisture must be managed.
Official product page ↗SCUDO SYSTEM® is the external positive-side route. Internally, BLOCKWATER stops local active ingress, WINPLASTER rebuilds and waterproofs the background, WINPOX CEMENT TIXO treats counter-pressure moisture, and WINFIX WET creates a two-component epoxy-cement base on moist cementitious substrates. None should be treated as a direct one-for-one alternative.
The field membrane is only part of the system.
The correct accessory depends on whether the detail is a corner, penetration, movement joint, wall-to-slab junction, reinforcement zone or local bituminous repair.
Self-adhesive butyl band for corners, changes in direction and local detailing.
Official product page ↗Preformed butyl pad for outlets, pipes and through-elements.
Official product page ↗Flexible band used to maintain waterproofing continuity across joints.
Official product page ↗Elastic sealant used as part of correctly formed joint details.
Official product page ↗Reinforcing fabric developed for the ONE system where movement or system design requires reinforcement.
Official product page ↗Heat-stabilised reinforcement used with compatible H₂O and 2021 system build-ups.

Official product page ↗Product knowledge is useful. System judgement is the real value.
Match the chemistry and build-up to substrate, moisture, exposure and intended use.
Coordinate joints, outlets, penetrations, upstands, reinforcement and terminations.
Translate the technical data sheet into a controlled and repeatable site method.
Review preparation, application conditions, continuity and issues before warranty stages.
This page describes the Winkler products supplied and supported through my professional work; it is not the complete Winkler catalogue and is not a project specification. ECOIMPRIMER, WIN BITUROOF, TIXO SEAL and the principal membrane must each remain in their correct role within a compatible build-up. Basement design must also consider water-table conditions, hydrostatic pressure, joints, wall-to-slab junctions, drainage, structural movement and the feasibility of external access. Final selection must follow a substrate assessment, project requirements, the current manufacturer technical data sheets and an approved system build-up.
