Large public aquariums & zoological parks
Integrity of acrylic panels, sealing systems and structures in live aquatic environments.
Large public aquariums combine giant acrylic panels, hyperbaric sealing, reinforced concrete and stainless steel in permanently aggressive water. MAREX inspects these assets underwater, with marine life present and without closing the facility to visitors.
Acrylic panels and tunnels
Surface condition, crazing, bonding lines and installation geometry of viewing panels.
Hyperbaric silicone seals
Primary and secondary joints, leak detection, protection against fauna and decoration.
Concrete, rebar and stainless steel
Corrosion mapping, cathodic protection anodes, stainless steel fittings in seawater.
Operation without shutdown
Underwater work planned with animal care teams, without draining or closing to the public.
