Smart Sealed is a professional waterproofing and building restoration company based in Australia. We specialise in concrete waterproofing, structural repairs, membrane installation, and protective coatings for residential, commercial and industrial properties. Our services are designed to prevent water damage, extend the life of structures, and protect assets from environmental wear and tear.
Waterproofing protects your property from water ingress that can cause structural damage, mould, corrosion and aesthetic deterioration. Water penetration may weaken concrete, timber and steel reinforcement, leading to costly repairs over time. Effective waterproofing preserves your building’s integrity, helps maintain indoor air quality, and enhances long-term durability. Smart Sealed provides solutions tailored to your specific site conditions.
Smart Sealed offers a wide range of waterproofing services, including:
- Concrete waterproofing for basements, balconies, rooftops and retaining walls.
- Membrane installation using liquid or sheet membranes.
- Roof waterproofing and leak detection.
- Structural crack injection and repair.
- Basement tanking and positive/negative side waterproofing.
- Concrete resurfacing and protective coatings.
Each service is delivered by trained technicians using premium materials suited to Australian climate and building standards.
Concrete waterproofing involves applying specialised barriers that prevent water from passing through porous concrete. These barriers may be liquid compounds, cementitious coats, crystalline additives or membrane systems. The correct choice depends on the structure, exposure to water, and performance requirements. Smart Sealed assesses each project to recommend the most effective method, ensuring long-lasting protection.
Positive side waterproofing refers to treating the side of the structure that faces incoming water pressure, such as the exterior of a retaining wall. This prevents water before it enters the substrate.
Negative side waterproofing treats the internal face of a wall where water has already penetrated, stopping leaks from behind. Both approaches are valid and the right choice depends on site access, water source and structural conditions.
The lifespan of waterproofing depends on the materials used, environmental exposure, and quality of installation. Many modern membrane systems can last 10–30 years or more with proper maintenance. Smart Sealed uses durable, weather-resistant systems designed for Australian conditions to maximise longevity. Regular inspections help identify any issues early and extend the life of your waterproofing investment.
Signs your property may need waterproofing include:
- Visible water stains on ceilings or walls.
- Damp or musty odours in basements or enclosed spaces.
- Cracks in concrete, brickwork, or render.
- Peeling paint or blistering coatings.
- Efflorescence (white powdery residue on surfaces).
- Water pooling around foundations or leak points after rain.
If you notice any of these signs, contact Smart Sealed for a professional assessment and solution.

Waterproofing provides a high-level barrier resistant to water pressure and is suitable for areas with significant exposure, such as basements or wet areas.
Damp proofing offers limited resistance to moisture and is typically used where water exposure is minimal. For long-term protection against leaks and structural damage, waterproofing is the preferred solution.
