Used in Many Industries

Aquadam’s concrete dams are widely used in a broad range of industry sectors including agriculture, aquaculture, mining, forestry and industrial chemicals.

In the agricultural sector, Aquadam’s gunite dams are used for irrigation, the storage of drinking water (livestock and human) and even as slurry tanks. Capacity ranges from as little as 19m3 all the way up to 1 550m3, allowing for exceptional versatility.

Because concrete is effectively fireproof and maintenance-free, Aquadam’s concrete reservoirs are widely used by Sappi and Mondi in the forestry industry for firefighting water storage.

When equipped with an optional concrete or steel roof, Aquadam’s concrete reservoirs are ideal for filtration systems, including the storage of both raw and filtrated water.

Aquadam’s concrete reservoirs are widely used in the mining and industrial industries for recycling grey water and for storing water and other liquids.

The ease, speed and cost-effectiveness of constructing Aquadam concrete reservoirs make them the ideal solution for potable water storage for colleges, schools, government departments and in rural and outlying areas.

Exceptional Durability

Aquadam’s Seamless Concrete Reservoirs are designed with South Africa’s extreme temperatures in mind, and are capable of withstanding temperature fluctuations ranging from -15°C in winter to 45°C in summer.

Installation is simple, using an easily maneuverable hose to deposit liquid gunite onto steel reinforcing to create a seamless, reinforced 35MPa concrete layer of between 100mm and 150mm in thickness.

L-bars, splice-bars and high-tensile hoop bars are used to counter excessive movement and to strengthen the structure even further, which is why Aquadam’s range of Seamless Concrete Reservoirs has a life expectancy of over 50 years.

Aquadam’s Seamless Concrete Reservoirs can be left open or they can be covered with shade cloth, PVC, steel sheeting or concrete.

Aquadam’s Seamless Concrete Reservoirs are designed to meet the stringent British Standard which allows for a 0.2mm crack width.
