    Waterproofing has been a concern pretty much as long as humanity has been around. In part, the need for waterproofing can be traced to our need for water itself. For example, waterproofing techniques are what allowed people to start living further and further from a water source. When there were ways to collect water in vessels that didn’t leak, pe...

    Even as early as the Neolithic era — which was roughly 12,000 years ago and considered the end of the Stone Age — people had an itch to travel and to migrate. Granted, it wasn’t necessarily to see the wonders of the world as we do now. As communities grew, exploration became a necessary byproduct, and as humanity explored further people began makin...

    The ancient Egyptians are arguably some of the best innovators when it comes to waterproofing techniques. Not only did they figure out a mummification process, they also managed to create waterproofing for buildings. When the Pyramids at Giza were finally opened in the present day, archeologists found that the interior spaces were incredibly well p...

    Of course, buildings and tools weren’t the only things to get waterproofing attention. Fabrics received a fair amount of focus in order to provide protection against the elements. Early methods involved coating fabric in wax to create a waterproof barrier for everything from sails to umbrellas. As technology improved, different methods were used to...

    Of course, plastic didn’t just help us improve waterproof clothing, it also opened up a wide array of options for other uses. Everything from party tents to billboards to waterproof paper has come from the combination of invention and ingenuity to give us the expanded uses that so many situations call for. This is, of course, where TerraSlate joins...

  3. Apr 1, 2021 · By the end of the nineteenth century, the use of wax also began to surge in popularity as a waterproofing method. The general consumer of the nineteenth century could weave wax-covered threads into clothing to give them waterproof fabric.

  4. Ancient cultures developed creative and often ingenious ways of waterproofing materials to protect them from weather and water damage. In ancient Egypt, for example, waterproofing was used on reed boats and papyrus, a form of paper made from a particular type of reed.

  5. Soda pulp was first manufactured from wood in 1852 in England, and in 1867 a patent was issued in the United States for the sulfite pulping process. A sheet of paper composed only of cellulosic fibres (“waterleaf”) is water absorbent. Hence, water-based inks and other aqueous liquids will penetrate and spread in it.

  6. One of the first forms of correction fluid was invented in 1956 by American secretary Bette Nesmith Graham, founder of Liquid Paper. With the advent of colored paper stocks for office use, manufacturers began producing their fluids in various matching colors, particularly reds, blues and yellows.
