Sub and Super Structure Works

Piling, foundations, and structural concrete — proven at Dangote Refinery,
Nigeria's biggest construction site.

What we do

The structural backbone. Proven at refinery scale.

Sub-structure and super-structure works are the most unforgiving part of construction — foundations, piling, reinforcement, formwork, and structural concrete have zero tolerance for shortcuts. It's also where Zizoh has proven itself at the highest level. At Dangote Refinery FZE (with Shapoorji Pallonji), Ibeju-Lekki, we executed the stalk foundation for HRSG2, the Oil Catcher 7 foundation, and sub-structure/super-structure packages — reinforcement, formwork, and structural concrete on one of Africa's largest industrial projects. That refinery-grade discipline — quality assurance, verifiable engineering indicators, certified materials — is what we bring to every foundation and structural package, whether it's an industrial facility, a commercial block, or piling for a difficult site.
