Penetron's crystalline technology was responsible for preventing the penetration of chlorides (from salt water) and increasing durability in the tunnels and tanks. PENETRON was installed to waterproof the tanks and aquariums, the foundation floor and the lift wells. In addition, the roof and the entrance area of the aquarium were treated against corrosion.
