Industrial Tank Waterproofing Services
TANK WATERPROOFING
Waterproofing your commercial or industrial tanks is essential to maintaining a leak-free water storage system. Minor cracks or leaks within waterproofing membranes can quickly escalate into major structural issues and flooding. They may also cause electrical hazards and lead to unforeseen compliance breaches.
As well as the tanks themselves, surrounding areas often require waterproofing. This includes zones frequently exposed to spills or runoff.
Raven Tanks have the expertise, equipment, and resources to install various membrane types. We tailor each solution to suit specific sites and industrial tank setups.

What Are Waterproofing Membranes?
Heavy-duty tank waterproofing membranes serve as a protective barrier. They prevent water from seeping into unwanted areas.
We apply these membranes using a range of proven, site-specific methods. However, it’s essential to select one that suits the specific application.
Raven Tanks brings over three decades of experience to every project. We expertly recommend and install waterproofing systems across a wide range of Australian industries.
Waterproofing Membrane Types We Apply
Tank waterproofing membranes come in various application types. Raven Tanks supplies a range of high-grade peel-and-stick, torch-on, and liquid products to enhance your tank’s storage capabilities.
Types of tank waterproofing membranes we apply include:
- Torch-on Membranes (single and double-layered) – A low-maintenance membrane solution consisting of bitumen and modified polymers. There are two types of torch-on membranes – Atactic Polyolefin Plastic (APP) and Styrene Butadiene Styrene (SBS).
APP membranes are best utilised in tanks exposed to consistent sunlight and extreme temperatures. We supply it in sheet form, and it bonds instantly when heat is applied. SBS membranes are more suitable for cold climates where less expansion of the tank’s surfaces occurs.
- Peel and Stick Membranes – Self-adhered and film-like, these are ideal for vertical surfaces with easy stick-on application. More suitable to metal tanks for longer-lasting adhesion.
- Liquid Membrane Applications – A gel-like sealant that fills micro-leaks and prevents future damage. We spray it on easily to deliver a high-strength, cost-effective waterproofing solution.
Concrete Tank Applications
Concrete based or walled tanks generally require a liquid barrier solution. This is usually the most appropriate protective layering method and often needs two coats to maximise its effectiveness.
Cracked containments are a common problem needing a membrane solution that’ll essentially ‘seal’ vulnerable surface areas.
Raven Tanks applies liquid polyurethane coatings to tanks and water storage areas with concrete surfaces. This ensures an enhanced, long-lasting level of waterproofing protection.
Arranging An Inspection – Why It’s Important
Monitoring your tank’s condition helps you plan and manage preventive maintenance effectively. Water leakages aren’t always noticeable to the untrained eye. They can take a long time to develop, worsen, and become a visible threat.
Water leaking onto access platforms, walkways, and other high-traffic areas creates a safety hazard. It may also result in liability if an accident happens due to a poorly maintained water storage system.

Client Questions – Our Answers
We know our clients often have important questions before starting a project. Here are clear answers to help you make informed decisions with confidence.
To build a waterproof concrete tank, the surfaces must first be properly prepared, cleaned, and leveled. We then apply a waterproofing membrane—such as epoxy, polyurethane, or liquid rubber—to actively seal pores and stop leaks. Reinforcing joints and corners is essential for long-term integrity.
Yes, food-grade epoxy coatings are safe for potable water applications. These certified coatings create a durable, non-toxic waterproof layer inside tanks.
Membrane waterproofing involves applying a flexible protective layer to tank surfaces. This layer—such as sheet, liquid, or torch-on membranes—prevents water from penetrating concrete or steel. It acts as a durable barrier and protects against leaks and chemical intrusion.
Waterproofing potable tanks begins with cleaning and preparing the surface. After that, certified food-safe products like liquid polyurethane, epoxy, or bituminous membranes are applied. Using materials that meet drinking water safety standards is essential.
