Tanking means applying a continuous waterproofing barrier to the outside (positive side) or inside (negative side) of a below-ground structure, preventing groundwater from reaching habitable space.
The same principle applies to cellar tanking in older buildings, where cellar waterproofing usually means treating solid masonry rather than a poured concrete box, and the barrier has to work around footings and joints rather than a clean surface.
Our Elaston-W80 polyurea is formulated as a seamless, spray-applied membrane rather than a sheet product, which changes what’s possible on site.
Liquimix basement sealing and waterproofing systems are designed for:
Case studies covering split-slab, under-slab and geofabric-backed shotcrete applications are available from our technical office on request.
Waterproofing in the basement rarely sits in isolation from the rest of a project’s coating scope. Explore our:
Every basement tanking project has different groundwater conditions and structural detailing. Book a free discovery session with our system designers, and we’ll help you choose between Type A, B and C protection, or a combination, based on your site rather than a generic spec sheet.
“Tanking” refers specifically to a barrier membrane or coating applied to a structure, equivalent to Type A protection under BS 8102. “Waterproofing” is the broader term and can include tanking, watertight concrete, or a drained cavity, often combined for higher-risk spaces.
No. Australia doesn’t currently have a dedicated standard for basement sealing and waterproofing, so designers generally reference BS 8102:2022, covering barrier, structural and drained protection types. The National Construction Code sets the performance outcome but not the method.
Yes, known as negative-side tanking, and it’s common in retrofits where excavating the exterior isn’t practical. It’s generally less reliable than positive-side application, since it doesn’t stop water from entering the structure, only its interior face.
Elaston-W80 is formulated to remain flexible and elastomeric for the life of the structure, with a service history exceeding 30 years in comparable applications. Actual lifespan depends on substrate preparation and detailing around penetrations and joints.
Often, yes, particularly in high water table or Grade 3 environments, where BS 8102 recommends combining a barrier membrane with a drained cavity. Our technical office can assess whether your site’s conditions call for a single system or combined protection.
Elaston-W80 adheres to concrete, shotcrete and geotextile fabric, including surfaces that aren’t fully cured or perfectly finished. It can be sprayed directly onto Geotuff-220 with no mechanical fixing required, making it suitable for blinding slabs and split-slab construction.

Extremely low vapor transmission rate — Pure Polyurea offers a very low water vapor transmission rate (Testing method E96-05 (B): 0.18 g/(h·m²)), which is lower than any elastomeric coating used in the industry. For that reason, pure polyurea is used inside water tanks as a primary lining.
Flexible & Durable— Elaston polyurea has excellent flexibility and elasticity, allowing it to accommodate movement in the substrate, and thermal expansion without cracking. This characteristic stays with Elaston for the entire lifespan of the product. (Over 30 years)
Adheres to less-than-perfect substrates—Elaston Polyurea has excellent adhesion to a variety of surfaces, providing a strong bond that prevents delamination. It can also be applied directly to geotextile even when there is no underlying substrate.
Permanently elastomeric— Elaston Polyurea comes with up to 400% elongation property, and it remains its property throughout its life. That helps the material to stay unaffected by movements in the substrate due to temperature fluctuations.
Ideal Balance of Toughness and Flexibility—A flexible, robust liner that offers high resistance to water and can protect the surface by having the hardness to tolerate direct impact, as well as high foot traffic, where sheet membranes tend to wear down quickly. The cushion effect produced by the Elaston’s elongation properties, offers an extraordinary resilience that is unmatched by any other product in the market, especially sheet membranes.

Protecting Industrial Floors from Acid and Chemical Exposure Industrial floors do more than provide a surface for workers, machinery and production equipment. In chemically demanding facilities, they can also act as a protective barrier between aggressive liquids and the concrete or steel beneath. When acids, cleaning chemicals, contaminated water and
