Why Waterproof Corrugated Sheets?
Corrugated sheets, whether made of metal, fiberglass, or PVC, are prone to leaks due to:
Overlapping joints that allow water seepage
Rust or corrosion over time
Expansion and contraction with temperature changes
Loose bolts or improperly sealed fasteners
Without proper waterproofing, even minor leaks can lead to:
Structural damage
Interior water stains
Mold growth
Increased maintenance costs
That’s why waterproofing is not just preventive—it’s protective.
Benefits of Corrugated Sheet Waterproofing
✅ Leak-Free Roofing
Seals all joints, gaps, and screw holes to prevent water ingress during rain.
✅ Rust Prevention
Waterproof coatings add a layer of protection that prevents rusting of metal sheets.
✅ UV & Weather Resistance
Coatings resist UV rays and extreme weather, reducing thermal expansion and roof wear.
✅ Energy Efficiency
Some waterproofing products reflect sunlight, reducing heat absorption and keeping indoor temperatures lower.
✅ Extended Roof Life
Prevents corrosion, degradation, and structural damage, adding years to your roofing system.
Common Waterproofing Methods for Corrugated Roofs
Elastomeric Waterproof Coating
This flexible, rubber-like coating expands and contracts with the sheet’s movement. It fills gaps, seals joints, and forms a continuous waterproof layer over the entire surface.
Bitumen-Based Coating
Often used on older or heavily rusted sheets, bitumen coatings are thick, durable, and waterproof. Ideal for industrial roofs.
Polyurethane Waterproofing
Highly elastic and weather-resistant, polyurethane coatings are perfect for metal roofs. They offer both waterproofing and insulation properties.
Acrylic Waterproof Paint
Best for homes and light commercial buildings. It offers basic water protection along with solar reflectivity to reduce heat.
Joint Sealing & Fastener Treatment
Special sealants are applied to bolt heads and overlaps to ensure no water can enter through the joints.
