The Fire Tank

The Fire Protection Water Tanks are manufactured with a steel plated sheet with the highest corrosion resistance available. It’s called PosMAC. This means that when you invest in a fire protection system you can be sure that your tank is designed according to the latest recognized code of practice so that it will last in any fire situation.  Our Fire Tanks are perfect for fire protection in the industrial, commercial and agricultural industry. Installation of your Fire Tank is carried out by one of our trusted fire tank dealers/installers in South Africa and abroad. Protect your assets with a PosMAC.

PosMAC Tank Shell

PosMAC is a Magnesium, Zinc and Aluminium alloy coating that acts differently to iron when exposed to the elements. The Al, Mg and Zn elements create a protective barrier coating to the tank shell on the inside and outside. This process allows the steel to be used safely for protracted periods and includes:

3 x higher corrosion resistant properties, Excellent anti-corrosive resistant flat surfaces and cut edges, High corrosive resistance against neutral salt & acid rain

High quality and lower replacement costs.

The cost factor is less than for existing fire tanks as it reduces maintenance and replacement costs due to corrosion as time progresses. A longer replacement period can help achieve a greater economic benefit. PosMAC will extend the life of any Fire Tank up to 50 years.

We have acquired the most technology advanced roll forming equipment & bending machinery to form and bend each steel coated tank exactly to your specific needs and specifications.


Our steel coated tanks is designed and manufactured on demand to last you a lifetime and guaranteed to give you peace of mind when you acquire a tank from Aquadam.


Every tank is build with the very best experienced and passionate workers as if it were there own. Installers are trained and certified to give you the most memorable experience during every installation process.


The owners of Aquadam has more than 50 years experience in the manufacturing and installation of water retaining structures from as small as 1500 liter tanks up to 5 Million liter tanks.


Every tank is optimally designed by a professional engineer to use the strongest and best materials available. Most of the materials is sourced locally to save on import duties and cost.


We have a great team of professional office personnel who makes it there duty to support each customer with there specific water storage needs in the shortest possible time.

Dome Roof Design

The Fire Tank roof is constructed using .55mm full hard zincalume corrugated sheeting. The roof is traffic-able across roof trusses, complete with a heavy-duty lockable access hatch. Furthermore, it is light and weatherproof, and designed to withstand wind speeds of up to 100 km/h. The Dome Roof can be fitted with a ventilator to prevent condensation on the inside and an internal or external ladder for easy access in and out of the tank. The roof can be sealed with a felt seal to make it bird, rodent and dust proof.

Modular Flexibility

The bolted nature of the tanks makes building very quick when compared to welded fire tanks or concrete structures. Engineered designs will accommodate secure tank storage for local environmental conditions, such as high wind speeds, snow or seismic loads. The bolted tank and silo system allows for structural designs to be used in various configurations, including fire protection water tanks, water storage reservoirs, water standpipes and elevated water distribution tanks. We guarantee that the Fire Tank will not leak for 20 years, with a pro-rata warranty available on request.

Anchoring Fire Tank

The Fire Tank foundations can vary depending on the size, the application and the design requirements of the tank. A reinforced concrete ring beam is required to anchor the tank, especially for larger tanks and for installations in extreme windy conditions. We can give you a detailed drawing and site instruction if you would like to construct the ring beam yourself.


The Fire Tank is available in capacities ranging from 15 m3 to more than 2 000 m3 and with a diameter ranging from 2,35mØ to 19,45mØ. Consequently, we offer a product for a wide range of specifications and requirements. PosMAC steel bolted tanks are suited for tough environments where dependability is vital. They can withstand extreme environments in any urban, rural, coastal or remote location. The modular design principle of the tank kits offers ease of transport and fast assembly on site.
