What Are Waterproofing Materials?
Waterproofing materials are various types of seals, paints, and special cement used to prevent water from entering or flowing out of buildings and other structures for a variety of reasons.
Watertight plates are used to protect houses and other structures from the large amounts of water that occur during heavy rains. Water sealing board is considered a type of waterproofing material.
Various types of watertight panels are available, depending on the location and size of the installation.
Uses of Waterproofing Materials
Waterproofing materials include waterproof cement, which can be packed into areas where water may enter and hardens in a relatively short time, waterproof seals that can absorb water when attached to concrete joints, and even waterproof paints.
On the other hand, watertight panels are used not only in ordinary houses but also in various other places to protect houses and other structures from large amounts of water intrusion.
These include subway entrances and exits, store entrances and exits, building and apartment entrances and exits, and underground parking lots.
Principle of Water Sealing Materials
As mentioned above, watertight panels are used not only in ordinary houses but also in various other places, and their performance is being evaluated.
Some manufacturers of watertight panels will conduct various leakage tests as performance tests of their products and present the results as a selling point of their products.
These include wave tests to evaluate the durability of watertight panels by generating simulated waves, water flow tests to evaluate the strength of watertight panels by varying the strength of the water flow, and stillness tests to evaluate whether the panels remain stationary at a certain point when a certain amount of water flows into them.
Watertight panels need to be designed based on the expected amount of water, the height of the watertight panel, impact resistance against drifting debris, and how to store the panels under normal conditions.
There are several types of watertight panels, including door type, motorized type, manual type, sliding type, swinging type, and detachable type.
As the name suggests, the door type is a type of water stop board that is shaped like a door. The electrically operated type is hidden from view during normal operation, and the panel is electrically activated to stop the water when it is in operation.
The manual type is similar to the motorized type, but is operated by hand. The sliding and swinging types differ according to the direction of movement of the panel. The detachable type can be removed and installed only when necessary, so it requires storage space, but it has advantages such as low cost and almost no maintenance.
