Protect Your Building from Water Damage, Dampness & Structural Deterioration
We offer professional waterproofing and damp proofing services in Nigeria for homes, commercial buildings, industrial facilities, water-retaining structures and infrastructure. At Ferrozoil Services Nigeria Limited, we identify the source of water ingress, assess the condition of the affected structure, and implement the right waterproofing system to help keep buildings dry, protected and durable.
Waterproofing Services Designed to Keep Water Out
Water penetration can start with a small leak, damp wall or moisture stain and develop into a much more expensive building problem.
Persistent moisture can contribute to peeling paint, damaged finishes, mould growth, concrete deterioration, corrosion of reinforcement and recurring maintenance costs.
Ferrozoil provides engineered waterproofing and damp proofing solutions designed around the source of the moisture, the condition of the structure and the level of water exposure.
Whether you are constructing a new building or dealing with an existing waterproofing failure, our team can assess the problem and recommend an appropriate solution.
With more than 20 years of industry experience and over 1,000 completed waterproofing projects, Ferrozoil provides waterproofing solutions for clients across Nigeria.
If you notice any of these issues, professional roof leak repair and waterproofing may be required.
Our Services
Our Waterproofing & Damp Proofing Services
At Ferrozoil, we apply industry-proven waterproofing systems tailored to the condition of your roof and the specific requirements of your building.
Roof Waterproofing & Leakage Control
Protect roofs, concrete decks and other exposed surfaces from rainwater penetration and recurring leaks. Our roof waterproofing solutions are suitable for new construction, renovation and existing structures experiencing water ingress.
Damp Proofing for Walls & Buildings
Damp walls can be caused by moisture entering through external walls, foundations, floors or other parts of a building. Ferrozoil assesses the source of the moisture before recommending a treatment system rather than simply covering the visible signs of dampness.
Concrete Waterproofing
Concrete may appear solid, but cracks, joints, pores and construction defects can create pathways for water penetration. We provide waterproofing solutions for concrete structures where moisture protection is critical to long-term performance.
Foundation & Below-Ground Waterproofing
Structures below ground can be exposed to soil moisture, groundwater and hydrostatic pressure. Our waterproofing approach considers the construction and condition of the structure before selecting the appropriate protection system.
Retaining Wall Waterproofing
Retaining walls are exposed to moisture from the surrounding soil. Without appropriate protection and drainage, water can migrate through the wall and create persistent dampness. Ferrozoil provides retaining wall waterproofing and moisture protection solutions designed to reduce water ingress and protect the structure from prolonged moisture exposure.
Reservoir & Water Tank Waterproofing
Water-retaining structures require waterproofing systems that are suitable for their specific application. Ferrozoil provides internal and external waterproofing solutions for: Underground reservoirs Overhead reservoirs Concrete water tanks Water storage structures Braithwaite/pressed-steel water tanks Other water-retaining structures
Exposed Concrete & Roof Gutter Waterproofing
Exposed concrete surfaces and roof gutters are continually exposed to rain, moisture and environmental conditions. Our waterproofing and felting solutions help protect vulnerable surfaces against water penetration, deterioration and recurring leakage.
What Causes Water Leakage & Dampness?
Waterproofing problems do not always originate where the water becomes visible.
A ceiling stain, damp wall or wet floor may be the result of water entering from another part of the structure.
Common causes include:
- Roof and terrace leakage
- Cracks in concrete
- Poorly sealed construction joints
- Ground moisture
- Rising damp
- Failed or inadequate waterproofing
- Water penetration through retaining walls
- Damaged gutters and drainage paths
- Defective tank or reservoir waterproofing
- Poor surface preparation
- Inappropriate waterproofing materials or application
This is why Ferrozoil begins projects with site inspection and technical assessment rather than applying the same waterproofing solution to every problem.

Frequently Asked Questions
Waterproofing is the process of protecting a building or structure against water penetration by using appropriate materials, systems and construction techniques.
The right waterproofing method depends on the location, source of water, substrate, level of exposure and structural requirements.
Costs vary depending on roof size, condition, accessibility, and selected waterproofing system. Contact Ferrozoil for a site assessment and quotation.
Properly installed systems can provide many years of protection depending on maintenance and environmental conditions.
Yes. After identifying the source of leakage, appropriate repair and waterproofing solutions can effectively stop water ingress.
The best system depends on the condition of the roof, expected traffic, exposure levels, and performance requirements.
Yes. We offer professional roof inspections and condition assessments.
Waterproofing is generally designed to provide stronger protection against water penetration, while damp proofing focuses primarily on controlling moisture and dampness.
The appropriate solution depends on the source and severity of the moisture problem and the requirements of the structure.
Common warning signs include:
- Damp walls
- Water stains
- Peeling paint
- Persistent moisture
- Roof leaks
- Wet floors
- Concrete cracks with water penetration
- Mould or musty odours
- Water seepage after rainfall
However, the visible symptom may not be the actual source of the problem. A professional site assessment can help identify the cause.
Yes. Ferrozoil provides roof waterproofing and leakage-control solutions for structures experiencing water penetration.
The appropriate treatment depends on the roof type, surface condition, source of leakage and existing waterproofing system.
Project duration depends on roof size and complexity.
Yes. We provide services nationwide.
Yes. Many aging roofs can be successfully restored with appropriate waterproofing systems.
Many modern waterproof coatings provide excellent UV resistance.
Contact our team via phone, WhatsApp, or the inquiry form to schedule an inspection.
Yes. Ferrozoil provides waterproofing solutions for concrete structures including exposed concrete surfaces, reservoirs, water tanks, foundations and other structures requiring moisture protection.
Yes. Ferrozoil provides damp proofing and moisture-control solutions for buildings and structures affected by dampness and water penetration.
Ferrozoil is based in Port Harcourt, Rivers State and provides engineering and waterproofing solutions for projects across Nigeria.
Waterproofing costs vary depending on the size of the area, type of structure, source of water, existing damage, waterproofing system required, materials and complexity of the work.
For an accurate estimate, Ferrozoil recommends a site assessment before preparing a quotation.
The service life of a waterproofing system depends on the system selected, surface preparation, installation quality, environmental exposure, maintenance and condition of the underlying structure.
A suitable waterproofing system should therefore be selected based on the specific project rather than using a one-size-fits-all approach.
Yes. Waterproofing can be carried out during new construction or as part of the repair and rehabilitation of an existing building.
The existing structure should first be inspected to determine the source and extent of water penetration.

Waterproofing Resources & Technical Standards
Waterproofing requires more than selecting a waterproofing product. The design, surface preparation, application method, materials and conditions of the structure all influence the performance of a waterproofing system.
For additional technical guidance and industry standards, these resources provide useful information for building owners, contractors, engineers and construction professionals.
ASTM D7832/D7832M provides guidance on performance attributes for waterproofing membranes applied to below-grade walls and vertical surfaces exposed to moisture and hydrostatic pressure.
