How Much Does Waterproofing Membrane Installation Cost?
The price of installing a liquid-applied waterproofing membrane typically ranges between $300 and $600 per square metre, but the final cost depends on the specific requirements of your project. Every job is different, and several key factors influence the overall pricing.
Below is a clearer breakdown of what can affect the cost of liquid membrane installation:
TYPE OF LIQUID MEMBRANE:
Liquid waterproofing products vary in performance, durability, and application methods. Some systems require multiple coats, reinforced fabrics, or extended curing times, which can increase labour and material costs.
SIZE OF THE AREA:
Smaller waterproofing areas often carry a higher cost per square metre because setup, preparation, and detailing take nearly the same amount of time as larger projects. Larger applications usually benefit from better economies of scale, resulting in a lower price per m².
FLOOR OR SURFACE CONDITION:
Any cracks, damaged concrete, uneven surfaces, or contaminants must be repaired or removed before applying a liquid membrane. Additional preparation or rectification work will impact the total cost.
ACCESSABILITY:
If the area is difficult to reach—such as tight balconies, rooftops with limited access, or confined internal spaces—extra time, safety measures, or equipment may be required, contributing to a higher installation price.
We Follow Australia’s National Standards And Guidelines
Across Australia, waterproofing systems must be installed in accordance with strict national standards. Our team only uses products and installation methods that align with these mandatory regulations, including:
AS 3740:2021 – Which outlines the requirements for waterproofing internal wet areas such as bathrooms and laundries.
AS 4654.1 & AS 4654.2:2012 – The governing standards for external and above-ground waterproofing membrane systems.
Different Types Of Waterproofing Membranes That We Install
At Concrete Cancer Repairs Sydney, we specialise in installing high-performance liquid-applied waterproofing membranes designed to protect your property from leaks, moisture intrusion, and long-term damage.
Liquid systems are ideal for both residential and commercial projects because they create a seamless, flexible barrier that can be applied to even the most irregular surfaces — including bathrooms, balconies, rooftops, planter boxes, and retaining walls.
Below are the main types of liquid waterproofing membranes we install:
Liquid Acrylic Waterproofing Membrane:
Acrylic membranes offer excellent UV resistance and flexibility, making them suitable for exposed areas and surfaces that experience movement.
Liquid Bituminous Waterproofing Membrane:
Bituminous coatings provide strong adhesion and durability, ideal for below-grade applications, retaining walls, planter boxes, and areas exposed to constant moisture.
Liquid Cementitious Waterproofing Membrane:
These polymer-modified coatings bond exceptionally well to concrete and masonry, making them a reliable choice for bathrooms, wet rooms, water tanks, and internal areas.
Liquid Polyurethane Waterproofing Membrane:
Polyurethane membranes are highly flexible and extremely durable. They are perfect for balconies, rooftops, and trafficable areas where long-term elasticity is required.
Liquid Rubber Waterproofing Membrane:
Liquid rubber forms a seamless, rubberised barrier with outstanding waterproofing performance. It’s ideal for roofs, gutters, planter boxes, and surfaces requiring thicker, high-build protection.
Liquid Solvent Based Waterproofing Membrane:
Solvent-based membranes use chemical solvents as their carrier, allowing for rapid curing and superior adhesion. They create a tough, flexible waterproof barrier that delivers excellent resistance to moisture, UV exposure, and corrosive environmental elements.
Why Professional Waterproofing Is Essential For Your Property
Professional waterproofing is one of the most important steps in protecting any residential or commercial structure. When applied correctly, a high-quality membrane prevents moisture intrusion, stops deterioration, and safeguards your building for the long term. When it’s done poorly, however, the consequences can be extremely costly. Here are the key reasons why expert waterproofing is so critical:
Protects the Structural Integrity of Your Building:
A properly applied waterproofing system blocks water from penetrating concrete, masonry, and other building materials. This prevents erosion, concrete breakdown, rusting reinforcement, and other issues that can weaken the structure over time.
Prevents Mould and Mildew Growth:
Moisture trapped within walls, floors, or subfloors creates the perfect environment for mould. Professional waterproofing eliminates this risk, helping maintain a healthier indoor environment.
Improves Indoor Air Quality:
Dry internal spaces reduce the likelihood of allergens, spores, and damp odours. This supports better respiratory health and creates a more comfortable living or working environment.
Extends The Lifespan Of Building Materials:
Waterproofed surfaces are far more durable and require less maintenance. By protecting the underlying materials, you significantly increase the longevity of your property.
Boosts Property Value:
A well-waterproofed property is more appealing to buyers and investors. It demonstrates proper maintenance and reduces future repair risks — both of which strengthen resale value.
Prevents Expensive Water Damage Repairs:
Water ingress can lead to crumbling concrete, rotting timber, swollen flooring, and internal structural damage. Waterproofing is a preventative measure that avoids these costly issues before they appear.
Maintains Energy Efficiency:
Moisture affects insulation performance, leading to heat loss and higher energy bills. A correctly sealed and waterproofed area keeps insulation working as intended.
Provides Protection Against Chemical and Environmental Damage:
Waterproofing doesn’t just block moisture — it also acts as a barrier against corrosive elements such as acidic rain, salts, and other contaminants that accelerate structural decay.
Supports Insurance Requirements:
Many insurers require adequate waterproofing for coverage, especially in wet areas or external structures. Poor or missing waterproofing can result in rejected claims during damage assessments.
Gives You Long-Term Peace of Mind:
Knowing your home or commercial building is protected from leaks, dampness, and moisture-related damage allows you to enjoy the space without unnecessary worry.
Investing in professional waterproofing membrane installation is one of the most effective ways to protect your property’s structure, value, and safety — both now and long into the future.
How Long Does It Take To Install A Waterproofing Membrane?
For most residential and small commercial areas, liquid waterproofing membrane installation typically takes 4 hours to 2 days from start to finish. Larger spaces or projects requiring extensive preparation may take longer, especially when multiple coats or repairs are needed. Below is a clear breakdown of common installation timeframes:
Small Areas: 4 – 12 hours:
Ideal for bathrooms, balconies, laundries, and wet rooms. These projects usually involve light preparation, one primer coat, and two waterproofing coats, with curing time between each stage.
Medium Areas: 1 day:
Planter boxes, roof sections, podiums, and moderate-sized commercial zones fall into this category. Additional preparation, drying time, and thicker membrane application extend the process.
Large or Complex Areas: 1 – 2 days:
Extensive waterproofing projects—such as rooftops, retaining walls, or multi-level external surfaces—require longer curing times, detailed preparation, and high-build membrane systems.
Key Factors That Affect Waterproofing Installation Duration
Several variables influence how long your waterproofing project will take:
NUMBER OF COATS REQUIRED:
Most liquid systems require at least two coats for full protection. High-performance membranes or exposed areas may need additional layers.
CURING TIME BETWEEN COATS:
Humidity, temperature, and airflow significantly affect drying times. Some products cure in a few hours, while others may need overnight drying.
CONDITION OF THE SUBSTRATE:
Subfloors that require crack repairs, patching, priming, or moisture treatment will extend the total installation time.
WEATHER CONDITIONS:
For outdoor areas, rain or high humidity can delay application and curing, especially on roofs, balconies, or external walls.
PRODUCT SPECIFICATIONS:
Different brands and membrane types have unique curing requirements and recommended application thicknesses.

What Is A Waterproofing Membrane?
A waterproofing membrane is a protective layer specifically designed to prevent water from penetrating surfaces. It acts as a barrier, safeguarding your property from moisture-related damage such as mould, mildew, corrosion, and structural deterioration.
These membranes are particularly crucial in areas that are frequently exposed to water, including bathrooms, kitchens, basements, balconies, and rooftops. By effectively sealing these surfaces, a waterproofing membrane not only extends the lifespan of your property but also helps maintain a healthier, safer living environment.
At Concrete Cancer Repairs Sydney, we use high-quality waterproofing membranes that comply with Australian standards, ensuring long-lasting protection for your home or commercial space.
Our Waterproofing Membrane Installation Process

Common Areas That Require Waterproofing Membranes
Water damage can compromise the structure, safety, and longevity of any property. At Concrete Cancer Repairs Sydney, we specialise in installing high-quality waterproofing membranes to protect vulnerable areas. The following are the most common zones that benefit from professional waterproofing:
Bathrooms and Laundries:
These are some of the most water-prone areas in both homes and commercial spaces. Leaks from showers, tubs, or washing machines can damage floors, walls, and cabinetry. Installing a reliable waterproofing membrane is essential to prevent water ingress and maintain long-term functionality.
Rooftops and Podiums:
Flat roofs and podium slabs are exposed to the elements year-round. Depending on the structure, we may use liquid-applied membranes, bituminous sheets, or reinforced fabric membranes to create a watertight barrier and protect the underlying building.
Balconies and Terraces:
Unprotected balconies and terraces are prone to cracking, tile lifting, and seepage into interior areas. A waterproof membrane beneath the surface safeguards the structure, especially in multi-story buildings where water damage can be costly.
Car Parks, Docks, Lift Pits and Tunnels:
Below-ground and heavily trafficked structures face constant water exposure. Specialised waterproofing membranes are used to withstand pressure, submersion, and wear, ensuring these areas remain safe and functional.
Decks:
Outdoor decks require protection from rain, UV exposure, and daily wear. High-quality membranes help prevent leaks and extend the lifespan of your deck and any underlying structures.
Basement And Below-Ground Areas:
Basements face pressure from groundwater and require robust waterproofing. Advanced membrane systems keep these spaces dry, habitable, and structurally sound.
Planter Boxes and Rooftop Gardens:
Green spaces on rooftops or within planter boxes can trap moisture against building surfaces. Waterproofing membranes prevent water damage, protect the structure, and support healthy plant growth.
Swimming Pools:
Pools and their surrounding decks are vulnerable to leaks and water damage. Membranes protect pool shells, walls, floors, and connecting structural elements to maintain watertight integrity.
Retaining Walls and Basement Walls:
Earth-retaining walls are subjected to hydrostatic pressure, which can drive moisture through unprotected surfaces. Applying positive or negative-side membranes ensures groundwater cannot penetrate, preserving the wall’s strength and durability.
