Concrete bunker for Aquafin

Aquafin, responsible for the development and management of water treatment infrastructure in Flanders, is building a new concrete bunker for sludge storage in Ghent. This structure is being built by contractor Besix, with AC Materials as concrete supplier, under the technical guidance of BM Engineering.

The concrete bunker is built with a sliding box and requires a continuous concrete supply (24/24). Due to the heavy chemical and physical stress (sludge storage up to 20 m in height, environmental classes EE3/XA2/XF1, etc.), sustainable, integral waterproofing was chosen with Penetron Admix SB.

Activities carried out

The concrete structure was protected by an integral crystalline waterproofing system. The project includes: Integral waterproofing of the foundation plate (approx. 753 m³) and walls (up to 2,360 m³) with Penetron Admix SB, added to the plant.

This approach provides sustainable protection against water penetration and significantly increases the lifespan of the bunker.
