Water Tank & Reservoir Waterproofing Services
Protect Your Water Storage From Leaks, Seepage & Water Damage
Ferrozoil provides water tank waterproofing and reservoir tanking services in Nigeria for underground and overhead water storage structures, including concrete reservoirs and Braithwaite (pressed-steel panel) tanks.
We assess the condition of the structure, identify areas requiring protection and recommend a waterproofing approach suited to the project.
Water Tank Waterproofing Built Around the Problem
Water should stay inside the tank—not find its way through walls, joints, cracks or other vulnerable areas.
But when a water-retaining structure starts leaking, simply applying a waterproofing product may not solve the underlying problem.
The first step is understanding where the water is coming from, where it is going and what condition the structure is in.
Ferrozoil provides water tank waterproofing services in Nigeria with this in mind. We assess the structure before determining the appropriate waterproofing or tanking requirements.
Our work covers
- Water tank waterproofing
- Reservoir waterproofing
- Underground reservoir tanking
- Overhead water tank waterproofing
- Concrete water tank waterproofing
- Braithwaite and pressed-steel tank waterproofing
- Internal waterproofing
- External waterproofing
- Remedial waterproofing for existing tanks
What Problems Can Water Tank Waterproofing Address?
If you are dealing with a leaking reservoir or water storage tank, you may notice:
Learn More
- Water seeping through concrete walls
- Cracks allowing water to escape
- Leakage around joints or penetrations
- Dampness around an underground reservoir
- Loss of stored water
- Deteriorating waterproofing
- Repeated leakage after previous repairs
- Moisture affecting surrounding structures
These signs should not simply be covered up.
The source and extent of the problem need to be understood before deciding on the appropriate repair and waterproofing approach.

Our Services
Our Water Tank & Reservoir Waterproofing Services Include

Concrete Water Tank Waterproofing
Ferrozoil provides concrete water tank waterproofing for new and existing water-retaining structures, with the scope of work determined by the condition of the tank and the requirements of the project.

Underground Reservoir Waterproofing
Ferrozoil provides underground reservoir waterproofing solutions designed to protect water-retaining structures from moisture, water pressure and leakage. Our approach considers the condition of the structure and the source of water ingress, with internal or external waterproofing applied where required.

Overhead Water Tank Waterproofing
Ferrozoil provides waterproofing solutions for overhead water storage structures based on their condition and project requirements.

Braithwaite & Pressed-Steel Tank Waterproofing
Ferrozoil provides waterproofing solutions for Braithwaite and pressed-steel panel water tanks, tailored to the tank’s condition, areas requiring protection and intended use.

Reservoir Tanking
Ferrozoil provides reservoir tanking solutions that protect water-retaining structures against water penetration and leakage, tailored to the structure and site conditions.

Internal vs External Water Tank Waterproofing
Ferrozoil provides both internal and external waterproofing solutions, depending on the condition of the tank or reservoir and the source of water ingress.
How We Waterproof a Water Tank or Reservoir
We follow a structured process so the waterproofing solution is based on the actual condition of the structure.
We examine the tank or reservoir and identify visible cracks, leaks, joints, penetrations, damp areas and other potential problem points.
We consider the condition of the structure and the likely source of water ingress or leakage.
Based on the assessment, we determine the appropriate scope of waterproofing, tanking or remedial work.
The affected surfaces are prepared according to the requirements of the selected waterproofing system.
The specified waterproofing system is applied to the areas requiring protection.
The treated areas are inspected and, where appropriate, tested before the structure is returned to service.
The completed work is handed over with the relevant project information and recommendations for ongoing care.
Waterproofing for New & Existing Water Storage Tanks
Building a New Reservoir?
Waterproofing should be considered during the planning and construction of a new water-retaining structure rather than waiting for leakage to appear.
Learn More
Ferrozoil can work with project owners and contractors to address the waterproofing requirements of new reservoirs and water storage structures.
If your project also requires [water reticulation services], we can connect the storage stage with the wider water distribution system.
Already Have a Leaking Tank?
Don’t assume that adding another waterproofing layer will solve the problem.
An existing tank should first be assessed to understand the condition of the structure and the source of the leakage.
Ferrozoil can assess the affected reservoir or tank and recommend the appropriate next step.

Water Tank Waterproofing for Residential, Commercial & Industrial Projects
Our waterproofing services can support water storage structures used across different types of developments.
For homes and private properties that depend on tanks or reservoirs for water storage.
For developers and estate managers requiring dependable water storage infrastructure across larger developments.
For hotels, offices, commercial facilities and other properties where reliable water storage is important to daily operations.
For industrial projects with water storage requirements connected to their wider water infrastructure.
For schools, healthcare facilities, government facilities and other institutions requiring protected water storage.
Your Water Storage System Is Part of a Bigger Infrastructure
A reservoir or water tank is only one part of a complete water system.
For many projects, the system looks like:
Groundwater Source → Borehole → Water Treatment → Water Storage → Water Reticulation → End Users
Ferrozoil can support several of these stages.
If you are still planning your water source, explore our Geophysical Survey Services for groundwater exploration and borehole siting.
If you need to understand the ground before construction or drilling, our Geotechnical Investigation & Soil Testing service can provide relevant subsurface information.
For water quality and treatment requirements, see our Water Treatment Services.
And when treated water needs to be distributed across an estate, facility or development, explore our [Water Reticulation Services].
This connected approach allows Ferrozoil to support more than one isolated component of your water infrastructure.
Water Storage, Waterproofing & Water Quality
Water storage structures must be designed and maintained with their intended use in mind.
For water intended for drinking or other sensitive applications, the suitability of materials and coatings that come into contact with the stored water should be considered carefully.
The American Water Works Association (AWWA) maintains consensus standards covering water treatment and supply, including standards relating to water-storage tanks, tank coatings and concrete water tanks. American Water Works Association

How Much Does Water Tank Waterproofing Cost in Nigeria?
There is no fixed price for every water tank waterproofing project.
The cost depends on factors such as:
- Tank or reservoir size
- Type of construction
- Location
- Condition of the structure
- Extent of leakage or damage
- Internal or external waterproofing requirements
- Surface preparation
- Repairs required before waterproofing
- Waterproofing system specified
- Accessibility of the structure
- Testing and finishing requirements
For this reason, Ferrozoil recommends a site inspection and assessment before providing a project-specific quotation.
