tarping

Tarpaulin, commonly called a tarp, is a large sheet of waterproof or water-resistant material used to cover and protect goods, equipment, or spaces from weather, dust, and debris. Tarps come in various materials, including polyethylene (PE), polyvinyl chloride (PVC), and canvas. Plastic tarps are usually lightweight and inexpensive; PVC-coated fabrics and laminated tarps offer greater strength and UV resistance, while canvas tarps provide breathability. Tarps typically have reinforced edges with grommets at intervals to allow tie-downs.

Applications include construction site cover, vehicle and equipment protection, outdoor event shelter, camping ground covers, and temporary roofs or storm protection. They are secured with rope, cord, bungee cords, or ratchet straps through the grommets, with techniques such as bowline or clove hitch knots used to minimize loosening. For durability, tarping practitioners place the tarp to shed water, leaving a slight slope to drain and preventing water pooling; additional reinforcement or seam taping is used for high-stress areas.

Maintenance and safety: dry tarps before storage, clean with mild soap and water, and store in a cool, dry place away from direct sunlight when not in use. Inspect for tears or loose grommets and repair as needed. Avoid using tarps near open flames; use caution in high winds, as wind can lift lightweight tarps and cause damage. Do not rely on tarps as permanent structures.

Etymology: the term tarpaulin is believed to derive from tar and pall or from Dutch sources, historically referring to tar-coated waterproof cloth used on ships.
