The Waterproof Myth
One of the most common questions about shipping containers is, "Are they waterproof?" While standard shipping containers are designed to keep cargo dry during transit, modifications and local conditions can influence their ability to remain fully watertight. For Australian industries, where extreme weather is common, ensuring containers are waterproof is critical.
At Modulate Group, we provide customised solutions that not only enhance waterproofing but also improve insulation and durability. Whether for storage, office spaces, or specialised facilities, our container designs are built to withstand Australia’s harsh conditions.
How Standard Shipping Containers Stay Dry
Shipping containers are constructed from durable, weather-resistant corten steel and designed to endure months at sea. Key features include:
Seamless Welds: Prevent water ingress at joints and edges.
Rubber Door Seals: Create a tight barrier against rain and moisture.
Corrugated Steel Panels: Reinforce strength while directing water away from the structure.
While these features are effective during transit, modifications or long-term use can introduce vulnerabilities. This is where Modulate Group’s expertise comes in.
Modulate Group’s Approach to Waterproofing
Colorbond Roofs with Guttering or Skillion Roof Options
For both standard and widened containers, Modulate Group offers Colorbond roofs with integrated guttering systems or skillion roof designs. These roofs:
Effectively channel water away from the structure, preventing pooling and leaks.
Resist corrosion, ensuring longevity in Australia’s coastal and outback climates.
Provide aesthetic and functional benefits for various applications.
Pro Tip: If your site experiences heavy rainfall, opt for guttering systems to improve water management.
Cork Condensation Barrier Coating
Traditional insulation methods, such as foam, can trap moisture and lead to mould. Instead, we offer cork condensation barrier coatings as an optional insulation upgrade. Benefits include:
Natural Breathability: Cork allows moisture to evaporate, reducing the risk of condensation.
Eco-Friendly: Made from renewable resources, it aligns with sustainability goals.
Durability: Withstands temperature extremes without degrading.
Pro Tip: Cork is ideal for climates with high humidity or fluctuating temperatures, making it a superior choice for moisture control.
EPS Insulation Options
For standard insulation, Modulate Group uses 50mm EPS panelling, with the option for thicker insulation depending on your needs. EPS panelling offers:
Thermal Efficiency: Maintains a stable internal temperature.
Lightweight Durability: Adds minimal weight while providing robust insulation.
Customisation: Can be adjusted to meet specific thermal performance requirements..
Pro Tip: Thicker insulation is ideal for containers used in extreme heat or cold conditions.
Fully Welded Construction
Unlike other companies that use stitch welding, Modulate Group employs fully welded construction techniques. This approach:
Provides superior structural integrity, ensuring no weak points where water could seep in.
Enhances durability for long-term use in harsh environments.
Ensures a seamless and watertight finish for added peace of mind.
Pro Tip: Fully welded containers are ideal for high-stress environments, such as industrial or remote site applications.
High-Quality Windows and Doors
Water ingress through windows and doors can be a common issue in modified containers. Modulate Group mitigates this by:
Using high-quality doors and windows with advanced manufacturing techniques.
Ensuring proper weatherstripping to seal gaps and prevent leaks.
Installing flashing correctly to direct water away from vulnerable areas.
Guaranteeing doors are properly aligned and fit snugly within their frames.
Pro Tip: Regular maintenance of weatherstripping and door alignment can further enhance long-term waterproofing.
Common Causes of Leaks and How We Mitigate Them
Corrosion
Over time, untreated steel can rust, leading to holes and leaks. Modulate Group uses high-quality materials, and applies industrial-grade paint to prevent corrosion.
Improper Modifications
Poorly executed modifications, such as cutting for doors or windows, can compromise waterproofing. Our expert team ensures all alterations are sealed to Australian Standards.
Roof Water Pooling
1. Flat roofs on standard containers can lead to water pooling. By incorporating skillion roofs or Colorbond alternatives, we eliminate this issue.
FAQs About Waterproofing Shipping Containers
Q: Are all shipping containers waterproof?
A: Standard containers are water-resistant, but modifications or extended use may require additional waterproofing measures. Modulate Group’s designs enhance durability and protection.
Q: How do cork condensation barriers compare to foam insulation?
A: Cork is a sustainable, breathable material that prevents condensation build-up, unlike foam, which can trap moisture and lead to mould.
Q: What insulation options are available for shipping containers?
A: Modulate Group offers 50mm EPS panelling as a standard, with options for thicker insulation to suit specific temperature control needs.
Q: Can Colorbond roofs handle heavy rainfall?
A: Yes, Colorbond roofs with integrated guttering effectively channel water away, preventing pooling and leaks, even in high-rainfall areas.
