Raincoat

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). For urban use raincoats and jackets are used; for outdoor activities in rough weather there is a range of hiking apparel.
A raincoat or slicker is a waterproof or water-resistant coat worn to protect the body from rain.

Waders (footwear)

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).
Waders denotes a waterproof boot extending from the foot to the thigh, the chest or the neck.

Pitch (resin)

The hulls of boats and ships were once waterproofed by applying tar or pitch.
Pitch may also be used to waterproof wooden containers and in the making of torches.

Liquid roofing

liquid waterproofing systems
Many types of waterproof membrane systems are available, including felt paper or tar paper with asphalt or tar to make a built-up roof, other bituminous waterproofing, ethylene propylene diene monomer EPDM rubber, hypalon, polyvinyl chloride, liquid roofing, and more.
Liquid Roofing is the process of waterproofing a roof by the application of a specialist liquid roof coating.

Construction

In building construction, waterproofing is a fundamental aspect of creating a building envelope, which is a controlled environment.

Tar paper

Many types of waterproof membrane systems are available, including felt paper or tar paper with asphalt or tar to make a built-up roof, other bituminous waterproofing, ethylene propylene diene monomer EPDM rubber, hypalon, polyvinyl chloride, liquid roofing, and more.
Tar paper is made by impregnating paper or fiberglass mat with tar, producing a waterproof material useful for roof construction.

Housewrap

building wrapbuilding wrapsmoisture barrier
Walls are not subjected to standing water, and the water-resistant membranes used as housewraps are designed to be porous enough to let moisture escape.
Housewrap functions as a weather-resistant barrier, preventing rain from getting into the wall assembly while allowing water vapor to pass to the exterior.

Basement waterproofing

waterproofing basements
Masonry walls are built with a damp-proof course to prevent rising damp, and the concrete in foundations needs to be damp-proofed or waterproofed with a liquid coating, basement waterproofing membrane (even under the concrete slab floor where polyethylene sheeting is commonly used), or an additive to the concrete.
Waterproofing a basement that is below ground level can require the application of sealant materials, the installation of drains and sump pumps, and more.

Asphalt

Many types of waterproof membrane systems are available, including felt paper or tar paper with asphalt or tar to make a built-up roof, other bituminous waterproofing, ethylene propylene diene monomer EPDM rubber, hypalon, polyvinyl chloride, liquid roofing, and more.
The use of natural bitumen for waterproofing, and as an adhesive dates at least to the fifth millennium BC, with a crop storage basket discovered in Mehrgarh, of the Indus Valley Civilization, lined with it.

Flat roof

Roofing materials are generally designed to be water-resistant and shed water from a sloping roof, but in some conditions, such as ice damming and on flat roofs, the roofing must be waterproof.
Applying a tough waterproofing membrane forms the ideal substrate for green roof planting schemes.

Basement

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).
Damp-proofing or waterproofing materials are typically applied to outside of the basement wall.

Polyvinyl chloride

Many types of waterproof membrane systems are available, including felt paper or tar paper with asphalt or tar to make a built-up roof, other bituminous waterproofing, ethylene propylene diene monomer EPDM rubber, hypalon, polyvinyl chloride, liquid roofing, and more.
PVC fabric is water-resistant, used for its weather-resistant qualities in coats, skiing equipment, shoes, jackets, aprons, and sports bags.

Durable water repellent

Durable water repellent, or DWR, is a coating added to fabrics at the factory to make them water-resistant (hydrophobic).

IP Code

IP67IP68IP rating
The IP Code, International Protection Marking, IEC standard 60529, sometimes interpreted as Ingress Protection Marking, classifies and rates the degree of protection provided by mechanical casings and electrical enclosures against intrusion, dust, accidental contact, and water.

Truscon Laboratories

It made waterproofing liquid chemical products that went into or on cement and plaster.

Tent

Some garments, and tents, are designed to give greater or lesser protection against rain.
Cotton absorbs water, so it can become very heavy when wet, but the associated swelling tends to block any minute holes so that wet cotton is more waterproof than dry cotton.

Waterproof fabric

waterproof/breathable fabricbreathabilityWaterproof breathable
They are usually natural or synthetic fabrics that are laminated to or coated with a waterproofing material such as rubber, polyvinyl chloride (PVC), polyurethane (PU), silicone elastomer, fluoropolymers, and wax.

Hiking apparel

For urban use raincoats and jackets are used; for outdoor activities in rough weather there is a range of hiking apparel.
Today's hiking apparel is more advanced than previous years, having material that can be wind resistant, water-repellent and yet breathable, and lightweight.

Hydrostatic head

Waterproofing should not be confused with roofing, since roofing cannot necessarily withstand hydrostatic head while waterproofing can.

Nanotextured surface

A 2013 study found that nanotextured surfaces using cone forms produce highly water-repellent surfaces.
In research published online October 21, 2013, in Advanced Materials, of a group of scientists at the U.S. Department of Energy's Brookhaven National Laboratory (BNL), led by BNL physicist and lead author Antonio Checco, proposed that nanotexturing surfaces in the form of cones produces highly water-repellent surfaces.

Damp proofing

Water resistant and waterproof often refer to penetration of water in its liquid state and possibly under pressure, whereas damp proof refers to resistance to humidity or dampness.

Permeation

Permeation of water vapour through a material or structure is reported as a moisture vapor transmission rate (MVTR).
