Waterproofing & Leakproofing
in Port Harcourt.
Coastal corrosion country. Heavy rainfall. Industrial and residential leakage at scale.
What makes Port Harcourt different.
- Climate
- Heavy rainfall April–October; very high humidity; coastal and oilfield exposure
- State
- Rivers
Port Harcourt has the most aggressive corrosion environment in mainland Nigeria. The combination of coastal salt, oilfield chemistry and heavy rainfall produces failure modes - chloride-induced rebar corrosion, sulphate attack on concrete foundations, pinhole leakage in roof membranes - that are unforgiving of mediocre specification. Serotny works across both the residential market in the GRA and the industrial market in the wider Rivers State industrial zones.
The Port Harcourt building stock
The Port Harcourt building stock includes a high concentration of 1970s and 1980s commercial concrete frames built for the oil industry, mid-century federal buildings, and a substantial post-2000 residential expansion in the GRA and adjoining estates. The older stock is approaching the age where reinforcement corrosion becomes the dominant structural concern.
Our team deploys from our Abuja headquarters to projects across Port Harcourt - bringing the same engineering standards we apply nationwide.
What we bring to Port Harcourt.
Coastal anti-corrosion specialism
Half-cell potential surveys, galvanic anodes, anti-carbonation coatings - this is what we are doing in Port Harcourt.
Heavy-rainfall waterproofing
Membrane systems and detailing specified for the Niger Delta rainfall profile, not the national average.
Industrial sector experience
Two decades of structural protection in oil-and-gas-adjacent industrial real estate.
