Australia Liquid Applied Membrane Market Size, Share, Growth and Forecast, 2025-2035

Housing targets and strata repairs lift waterproofing demand

The Australia liquid applied membrane market was valued at USD 388.5 million in 2025 and is projected to increase from USD 417.6 million in 2026 to USD 794.1 million by 2035, registering a CAGR of 7.40% during 2026–2035. Demand comes from builders, waterproofing applicators, tilers, roofers, strata remediation contractors and civil contractors that buy polyurethane, cementitious, acrylic and specialty coatings for wet areas, roofs, balconies and below-grade structures. New South Wales held the largest regional share, 30.9% in 2025, because Sydney has the largest stock of apartment buildings needing new and repair waterproofing. Queensland is the fastest-growing region at 7.97% a year, as dwelling approvals there held up better than in the two largest states. In turn, the national target of 1.2 million new homes from mid-2024 keeps builders ordering membranes for bathrooms, balconies and roofs.

Which coatings and uses does the estimate count?

The estimate measures spending in Australia on liquid applied waterproofing membranes, including polyurethane, cementitious, acrylic elastomeric and specialty chemistries such as polyurea and hybrid systems. It counts products used on roofs, internal wet areas, below-grade structures and external and civil surfaces. Values are stated in USD million at current prices and exclude goods and services tax and installation labor.

The estimate excludes sheet membranes, torch-on bitumen rolls, sealants sold separately, crystalline admixtures and tile adhesives. The value chain runs from local and overseas makers through trade distributors, hardware stores and direct project supply to waterproofers, builders, remediation contractors and homeowners.

Polyurethane leads while specialty chemistries grow fastest

Why does polyurethane hold the largest share?

Based on product type, the market is categorized into polyurethane, cementitious, acrylic elastomeric and specialty chemistries. Polyurethane led with a 38.0% share of 2025 value, because it stays flexible on balconies, roofs and wet areas that move with heat. Specialty Chemistries grow fastest at 8.26% a year, as remediation and civil contractors use fast-curing polyurea and hybrid coatings.

Why do bathrooms and laundries take most volume?

Based on application, the market is categorized into roofing, internal wet areas, below-grade structures and external and civil surfaces. Internal Wet Areas led with a 34.0% share of 2025 value, because every new or renovated bathroom and laundry needs a code-compliant membrane. External and Civil Surfaces grow fastest at 7.95% a year, as balconies, podiums and civil decks are repaired or built.

Homes, offices or infrastructure owners?

Based on end user, the market is categorized into residential buildings, commercial buildings, civil infrastructure and industrial facilities. Residential Buildings led with a 52.0% share of 2025 value, because houses and apartments use membranes in every wet area. Civil Infrastructure grows fastest at 8.09% a year, as bridges, tunnels, car parks and water assets need long-life protection.

Why do trade counters still sell most product?

Based on sales channel, the market is categorized into trade distribution, manufacturer direct and consumer retail. Trade Distribution led with a 56.0% share of 2025 value, because waterproofers and tilers buy from trade stores near their jobs. Manufacturer Direct grows fastest at 7.73% a year, as specified systems for large projects are supplied straight from makers with technical support.

New homes, defect repairs and code rules drive demand

How does housing delivery lift membrane demand?

Housing delivery lifts membrane demand, because every new house and apartment needs waterproofing in bathrooms, laundries, balconies and often roofs. National Cabinet set a target of 1.2 million new well-located homes over five years from July 1, 2024, according to the Treasury. The plan includes AUD 3.5 billion in payments to states and territories and an AUD 3 billion New Home Bonus for those that beat their share. In August 2026, seasonally adjusted dwelling approvals were 16,953, up 10.3% on a year earlier, while private house approvals rose 18.4%. As a result, residential buildings keep a 52.0% share of 2025 value, and internal wet areas remain the largest application.

Why does strata remediation support repair demand?

Strata remediation supports repair demand, because older apartment buildings often leak through balconies, roofs and wet areas and must be fixed under owners corporation programs. A 2025 survey found serious defects in 53% of New South Wales strata buildings, with waterproofing the most common at 22%, according to the NSW Government. The survey ran from June 18 to Aug. 31, 2025, and drew 520 responses, a 42% response rate. Victoria merged three bodies into the new Building and Plumbing Commission on July 1, 2025. Consequently, external and civil surfaces grow fastest among applications at 7.95% a year, as balcony and podium repairs move from reports to contracts.

How do compliance specifications raise product grades?

Compliance specifications raise product grades, because builders must now prove that wet area membranes meet updated national rules and tested standards. NCC 2022 references the 2021 edition of AS 3740 for domestic wet areas in place of the 2010 edition, according to the code's publisher. The code split wet area provisions into two clauses, H4D2 and H4D3, and added Part 10.2 to the Housing Provisions. Most NCC 2022 changes applied from May 2023, while Western Australia adopted them later in 2025. In turn, polyurethane keeps a 38.0% share, and specified systems lift manufacturer direct sales to builders who must document every wet area.

Why does steady construction investment widen use?

Steady construction investment widens use, because roofs, car parks, podiums and water assets all need durable waterproofing. Gross fixed capital formation equaled 24.3% of GDP in 2025, up from 24.1% in 2024, according to the World Bank. The value of residential building approved was AUD 11.30 billion in August 2026, according to the statistics bureau. Approvals for dwellings excluding houses reached 5,674 in the same month, keeping apartment work in the pipeline. As a result, wider building construction activity supports civil infrastructure, which grows fastest among end users at 8.09% a year, as transport and water projects specify long-life coatings.

Full systems, supplier mergers and remediation gain ground

How is the shift to complete tested systems changing sales?

The shift to complete tested systems is changing sales, because applicators now buy primers, tapes, bond breakers and membranes from one maker to meet AS 3740-2021. Laticrete Australia launched a new range that includes Hydro Barrier, Hydro Tape and Primer RTU alongside its Hydro Ban membrane. Sika Australia sells liquid applied, spray applied and sheet membranes in one waterproofing portfolio used in housing and commercial building construction. Ardex Australia offers undertile waterproofing and roofing membranes with tile adhesives and levelers. Consequently, manufacturer direct supply grows fastest among channels at 7.73% a year, as specifiers name full systems for each job. NCC 2022 adds weight to this shift, since most of its changes applied from May 2023, with Western Australia following in 2025.

Why is supplier consolidation rising?

Supplier consolidation is rising, because global building material groups want broader ranges of construction chemicals in the Asia Pacific. Saint-Gobain completed its acquisition of Fosroc in February 2025, a deal first announced on June 27, 2024. Fosroc had about 3,000 employees and 20 manufacturing plants at the time of the deal. In Australia and New Zealand, Fosroc products are supplied by Parchem, a wholly owned subsidiary of DuluxGroup, which sells to builders and contractors nationwide. As a result, large distributors gain wider waterproofing ranges, while local makers such as Crommelin, active since 1957, compete on brand, stockist networks and trade reach.

Can remediation open a larger repair market?

Remediation opens a clear opening, because many buildings completed in the last two decades now need balcony, roof and podium repairs. Waterproofing defects were found in 22% of NSW strata buildings in the 2025 survey, ahead of other defect types, drawing on 520 completed surveys. Victoria's new commission brings together the building authority, domestic building dispute resolution and domestic building insurance from July 1, 2025. Gripset Industries runs a waterproofing course for trades and sells liquid, sheet and cement-based systems. Consequently, demand for waterproofing chemicals used in repair work grows faster than new-build volumes, as owners fund remediation programs over several years.

Is there room in civil and below-grade work?

Civil and below-grade work offers room to grow, because tunnels, basements, water tanks and car parks need membranes that resist constant water pressure. Australia was 87.7% urban in 2025, according to World Bank data, which keeps building activity concentrated in dense cities with basements and podiums. Approvals for dwellings excluding houses reached 5,674 in August 2026, most of them apartments with basements, podiums and roof decks. Soprema Australia supplies Alsan flashing and Flagon PVC systems for roofs and structures. Fosroc Australia supplies concrete repair, waterproofing, grouts and protective coatings for infrastructure. As a result, cementitious products compete with crystalline waterproofing for basements, while civil infrastructure grows fastest among end users.

Installer skills, weak approvals and costs slow growth

Why do installer skills limit performance?

Installer skills limit performance, because membranes fail when surfaces are poorly prepared, coats are too thin or curing times are skipped. As a result, defects often appear years later and lead to costly repairs for owners. Waterproofing was the most common serious defect in the 2025 NSW strata survey. Suppliers respond with training courses, installation checklists and site support for applicators and builders, and some run their own waterproofing courses for trades.

How do uneven approvals slow orders?

Uneven approvals slow orders, because membrane volumes follow the number of homes and apartments that reach construction. Victoria recorded 3,514 approvals in December 2025, its worst monthly result since June 2013. In turn, applicators in some states face gaps in work between projects. Suppliers respond by shifting sales effort toward remediation, commercial refurbishment and civil projects that follow different cycles and funding sources.

Why do raw material costs pressure margins?

Raw material costs pressure margins, because polyurethane, acrylic and specialty membranes use resins, solvents and additives traded on global markets. Consequently, price changes overseas pass through to local distributors and builders with little delay. Small applicators struggle to absorb these changes on fixed-price contracts and must either cut margins or seek price changes. Suppliers respond with local production, longer supply agreements and lower-cost formulations for value-grade work.

Can buyers manage warranty and liability risk?

Warranty and liability risk is a barrier, because builders and waterproofers can be held responsible for leaks for many years after handover. As a result, buyers prefer branded systems with test reports, although these cost more than generic products. New regulators in NSW and Victoria are increasing scrutiny of defects in apartments and houses. Suppliers respond with system warranties, technical data sheets and inspection support for builders and applicators.

New South Wales leads while Queensland gains fastest

Strata repairs keep New South Wales ahead

New South Wales held a 30.9% share of 2025 value and grows at 7.47% a year. The state recorded 4,428 dwelling approvals in trend terms in August 2026, down 2.6% on the month. Its 2025 strata survey found serious defects in 53% of buildings, with waterproofing the most common. As a result, the state combines new apartment work with the largest strata remediation demand for balcony, roof and podium membranes.

Why does the rest of Australia hold a large share?

Remaining Australia held a 27.1% share of 2025 value and grows at 7.27% a year. Western Australia recorded 2,285 trend approvals in August 2026 and South Australia 1,490, up 2.9% on the month. Western Australia adopted the NCC 2022 waterproofing changes later than other states, in 2025. Consequently, house building in Perth and Adelaide and mining-related civil works keep demand broad across the smaller states and territories.

Melbourne apartments anchor Victoria

Victoria held a 23.0% share of 2025 value and grows at 6.97% a year. The state recorded 4,942 trend dwelling approvals in August 2026, the most of any state. Victoria's Building and Plumbing Commission began operations on July 1, 2025, with stronger oversight of building work. In turn, demand comes from house building in growth suburbs and apartment work in Melbourne, although approvals fell sharply in December 2025.

Why does Queensland gain fastest?

Queensland held a 19.0% share of 2025 value and grows fastest at 7.97% a year. The state recorded 4,462 trend dwelling approvals in August 2026, up 1.0% on the month while New South Wales and Victoria fell. Its wet climate and storms also raise demand for roof and balcony coatings. As a result, Queensland adds membrane demand fastest across new homes, apartments and civil works.

Housing targets, regulators and supplier deals, 2024–2026

Water-based, reactive and solvent-borne systems compete

• Water-based systems use acrylic and polymer-modified cement chemistry that is easy to apply indoors, which suits most bathrooms and laundries.
• Solvent-free reactive systems use polyurethane, polyurea and hybrid chemistry that cures into thick, tough films for balconies, roofs and civil decks.
• Solvent-borne systems use traditional polyurethane and bitumen chemistry that cures fast outdoors, although ventilation and odor rules limit indoor use.
• Tested complete systems combine primers, tapes, bond breakers and membranes from one maker, which helps builders show compliance with AS 3740.

Global suppliers and local makers compete on systems

Competition combines global construction chemical groups with Australian makers that hold strong trade brands. Sika Australia sells liquid applied, spray applied and sheet membranes, while Ardex Australia offers undertile and roofing membranes with its tiling systems. Laticrete Australia launched a new range around its Hydro Ban membrane. Tremco supplies waterproofing systems with technical support at every project stage, and Soprema Australia sells roof and flashing systems. Crommelin has served the market since 1957 with Wetite shower membranes, while Gripset Industries sells liquid, sheet and cement-based systems. Fosroc products reach Australian builders through Parchem, a DuluxGroup subsidiary. Mapei and Bostik also sell in Australia, although their local membrane activity was not verified for this report. Companies compete on system range, training, trade reach and price.
