Waterproof Coating & Liquid Membrane Systems for Internal Sealing, Concrete Protection & Moisture Control

Water doesn’t need much to get in. A small pathway through concrete, a porous surface or an untreated internal wall is enough for moisture to start working its way through. Once it’s inside, damage builds behind the surface, weakening materials, causing mould & breaking down structural integrity over time. Soudal Incoat systems are built to stop that at the source. These are waterproof coating & liquid membrane solutions designed to seal internal surfaces, block moisture & protect structures from the inside out.

Across construction sites, civil work & maintenance environments, this range includes liquid waterproof coatings, internal membrane systems & concrete sealing compounds designed for long-term protection. Whether sealing basements, internal walls, tanks or concrete structures, these coatings form a continuous barrier that prevents water ingress while maintaining adhesion under real conditions.

To complete the system, trades pair these with Adhesives & Tapes, Roof Sealants & Adhesives & Concrete Repair & Restoration. For proper preparation & consistent application, using Hand Tools, Measuring & Layout Tools, Clamps & Vises & Safety & Personal Protective Equipment ensures surfaces are ready before coating begins.

What’s in This Collection:

► Liquid waterproof coating (internal membrane system)
‣ Forms a seamless barrier to stop water ingress through concrete & masonry

► Internal waterproofing membrane
‣ Protects basements, walls & enclosed structures from moisture penetration

► Concrete sealing coating (protective barrier)
‣ Seals porous concrete surfaces to prevent water absorption

► Waterproof coating for walls & cavities
‣ Blocks moisture movement within internal wall systems

► Tanking membrane coating
‣ Designed for water-retaining structures like tanks & containment areas

► High-adhesion waterproof coating
‣ Bonds strongly to prepared substrates for long-term durability

► Flexible membrane coating
‣ Handles movement, expansion & structural shifts without cracking

► Multi-surface waterproof system
‣ Adheres to concrete, masonry & mixed structural materials

Across real jobs, one system doesn’t cover everything. Membrane coatings for waterproofing, sealing compounds for concrete, flexible systems for movement. That combination ensures internal protection holds under pressure.

Trade Applications for Soudal Incoat Systems

Across trades, internal waterproofing systems are used where moisture damage starts behind the surface.

► Basement waterproofing & internal wall sealing
 ‣ Prevents water ingress through below-ground structures

► Concrete tank & containment sealing
 ‣ Protects water-retaining structures from leakage

► Internal wall & cavity waterproofing
 ‣ Stops moisture migration within structural systems

► Concrete surface sealing & protection
 ‣ Reduces porosity & prevents long-term degradation

► Industrial & commercial waterproofing applications
 ‣ Maintains structural integrity in high-moisture environments

► Maintenance, repair & refurbishment work
 ‣ Restores waterproofing in existing structures

Across construction, civil projects & maintenance teams, internal waterproofing systems stop damage before it becomes structural.

Water Gets In Quietly. The Damage Doesn’t Stay Quiet.

Moisture doesn’t cause immediate failure, it builds slowly behind surfaces where it’s harder to detect. Over time, that leads to weakened concrete, internal damage & costly repairs that could have been prevented early.

Soudal Incoat waterproof coatings are designed to stop that process at the source. Liquid membrane systems seal internal surfaces, block water pathways & maintain protection under pressure. That’s critical for basements, tanks, walls & any structure exposed to ongoing moisture.

Where substrates are damaged or unstable, using Concrete Repair & Restoration ensures proper adhesion before coating. For external sealing alongside internal systems, pairing with Roof Sealants & Adhesives completes full waterproof protection.

Orders are processed with Same day dispatch, & for ongoing project supply, support is backed through Trade support Solutions to keep materials available when needed.

► Waterproof coating & membrane systems built for internal protection
► Proven performance across basements, concrete & structural sealing
► Bulk supply options for contractors, civil work & maintenance teams
► Fast Australia-wide delivery to keep projects moving

Stop the Water Before It Becomes the Problem

Once moisture gets inside, the damage spreads where you can’t see it. The right waterproof coating system stops it before it starts.

Seal it properly, apply the right membrane & protect the structure from the inside out.
