About Us

Hein van Spaendonck (HvS), a serial entrepreneur, established Flexitank Systems (FTS) in 2002 from the remnants of the Rubber tank division of Dunlop Industrial Products (DIP) ‘mothballed’ since 1996, operating from Howick, as a 50/50 JV, between HvS and DIP.

The business took on new life (including internationally), under HvS directorship up until 2005. At this time Dunlop division, unbeknown to HvS, made ill advised ‘cost saving’ alterations in the fabric of the rubber compound, which compromised its integrity, and resulted in newly produced tanks leaking in the market place.  

During our initial trading years, HvS natural vocation towards optimisation, along with being a textile engineer trained in the Netherlands, HvS developed many new products with more modern and updated designs and materials along with optimal production methods.

As a result of DIP’s action in compromising the integrity of the then failing rubber materials, there was no longer a role for DIP to play in FTS and the JV ceased trading.

In 2006 a new FTS- Flexitanks Systems was established as a manufacturing arm, under van Spaendonck Trading CC a Holding company.

The growth in the business has been substantial and in the last few years the business has become more demanding. Since the beginning of 2020, under the specialist knowledge of Willem Pieterse, a newly appointed director of FTS, FTS is now also involved in another expansion of its offerings. Namely, the production and building of pressed steel panel tanks and Aluzinc round tanks with sizes ranging from 10 000 liter up to 4 million liters for the civil, building and mining industry.

The business is built on a solid engineering and practical administration model and continues to grow from strength to strength
