WHAT WAS THE FIRST WATERPROOFING USED?

In the journey of human development, protecting construction works and objects from the effects of water has always been a great challenge. Although water is essential for life, it is the number one enemy of materials and structures.

So, have you ever wondered: What was the first waterproofing material used in the world?

Let's explore with Hung Thinh Waterproofing the interesting history of the waterproofing industry, from primitive materials in ancient times, to see that the need for waterproofing has existed and developed throughout human history.

First of all, when learning about the history of waterproofing, the name that is mentioned the most and has the earliest evidence is Bitumen (also known as natural asphalt or pitch).

Bitumen: The Grandfather of Waterproofing Materials:

- Appearing from the 5th millennium BC: Archaeologists have found evidence of the use of bitumen for waterproofing from around the 5th millennium BC (more than 7000 years ago) in ancient Mesopotamia, now Iraq. Natural bitumen is a thick, black substance, derived from petroleum that leaked onto the earth's surface, which was exploited by the Sumerians and later civilizations.

- Uses of Bitumen: The Mesopotamians used bitumen to coat mud bricks (adobe), as a waterproofing layer for buildings and irrigation structures. A typical example is the "Great Bath" at Mohenjo-Daro (Indus Valley Civilization, c. 3000 BC), described as "the earliest public water tank of the ancient world". In addition, archaeologists have also discovered that the ancient Egyptians used a form of bitumen emulsion to waterproof the foundation stones of the Giza Pyramids, helping to protect the interior spaces from the intrusion of Nile floodwaters.

And the second type of waterproofing material used in history is clay membrane.

In many ancient civilizations, clay was used as a waterproofing layer.

The Babylonians and Egyptians used clay layers to prevent water from seeping into their constructions such as ponds, reservoirs, house foundations, etc.

And the third type of material that can be mentioned is waterproof mortar:

The ancient Romans advanced waterproofing technology by developing opus signinum, a special mixture of lime, sand and crushed bricks (or volcanic ash - pozzolana). This mixture, when hardened, formed a mortar with excellent waterproofing properties, widely used for public baths, aqueducts and large water tanks.

From the above primitive materials, the waterproofing industry has undergone a remarkable development process, especially from the 19th century onwards with the advent of industrialization and chemistry, many new products were invented with a series of improvements such as: cement-based waterproofing membranes, improved bitumen waterproofing membranes, Polyurethane waterproofing membranes, Polyurea,...

Although technology changes, the core principle remains the same: creating a solid protective layer to prevent water from penetrating. At Hung Thinh Waterproofing, we are proud to inherit and promote the quintessence of the waterproofing industry, applying the most modern technologies and materials to bring thorough, sustainable and professional waterproofing solutions to all projects.
