Waterproofing is the process of making objects or structures impervious to water. It’s the reason your basement doesn’t flood and your raincoat keeps you dry.
From Ships to Smartphones: A Brief History
Waterproofing isn’t new. Ancient sailors slathered their ship hulls with tar and pitch to keep the sea out. Today, we use high-tech coatings and membranes to protect everything from buildings to electronics.
Building Barriers: Waterproofing in Construction
In construction, waterproofing is crucial. It’s not just about keeping things dry – it’s about protecting structural integrity and preventing mold growth.
Roofs: More Than Just Shingles
Your roof does more than just look pretty. It’s a complex system designed to shed water. But sometimes, that’s not enough. In areas prone to ice dams or on flat roofs, waterproof membranes are essential. These can be made from materials like EPDM rubber or PVC.
Walls and Foundations: The Underground Battle
Below ground, it’s a constant fight against moisture. Builders use techniques like “tanking” – fully encapsulating basement structures in waterproof membranes – to keep water out. For less severe conditions, damp proofing might be enough.
Keeping You Dry: Waterproofing in Clothing
Ever wonder why some rain jackets work better than others? It’s all about the waterproofing.
- Showerproof: Good for light drizzle
- Water-resistant: Can handle a bit more rain
- Waterproof: Bring on the downpour
The best waterproof garments use breathable membranes. These keep water out while letting sweat escape. Without this, you’d end up as wet from your own perspiration as from the rain!
Tech Stays Dry: Waterproofing Electronics
Remember when dropping your phone in water meant certain death? Not anymore. Many modern smartphones use nano-coatings – incredibly thin layers that repel water at the molecular level. It’s like giving your phone an invisible, water-hating forcefield.
The Future is Superhydrophobic
Scientists are always pushing the boundaries of waterproofing. In 2013, researchers created surfaces with tiny cone-shaped structures at the nanoscale. These “nanocones” are so water-repellent, they’re called superhydrophobic. Imagine never having to clean your windows or worry about rust again!
Waterproofing might not be the most glamorous topic, but it’s a critical part of our modern world. From keeping our homes dry to protecting our gadgets, it’s an invisible hero in our daily lives.

Waterproofing is the process of making an object, person or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions. Such items may be used in wet environments or underwater to specified depths.
Water-resistant and waterproof often refer to resistance to penetration of water in its liquid state and possibly under pressure, whereas damp proof refers to resistance to humidity or dampness. Permeation of water vapour through a material or structure is reported as a moisture vapor transmission rate (MVTR).
The hulls of boats and ships were once waterproofed by applying tar or pitch. Modern items may be waterproofed by applying water-repellent coatings or by sealing seams with gaskets or o-rings.
Waterproofing is used in reference to building structures (such as basements, decks, or wet areas), watercraft, canvas, clothing (raincoats or waders), electronic devices and paper packaging (such as cartons for liquids).
