Waterproofing refers to the procedure of making an outer object or structure resistant to water, usually by sealing it from air and exterior water. These seals are often applied to keep water out of certain objects like doors and windows, or to prevent damage due to leakages. Common applications of waterproofing materials include tanks, storage bins, doors, roof eaves, and sealants for concrete slabs, bricks, etc. These items can also be used underwater to specified depths for protecting valuable property from water damage. In fact, leaks beneath the surface can be detected long before actual damage occurs.
Waterproofing employs several techniques for achieving its result. The most common ones are primary coating, water absorption, secondary coating, and sub-micron films. It is possible to employ any or all of them in a given building project depending upon the extent of water resistance needed for that purpose. But for ordinary purposes, primary coatings are a practical option because they are easy to apply, cheaper and faster acting.
Primary waterproofing involves spraying a coating on an area such as a basement floor, walls, ceilings, and concrete floor. Though concrete waterproofing is quite simple, it can be applied for industrial, residential, and commercial buildings. This is a necessary measure to make such areas waterproof since most of the time, they can be wet and are susceptible to damages due to mold and mildew. Besides, leaks in areas like these are not only inconvenient, but expensive as well.
A typical application for concrete waterproofing involves applying a high-quality crystalline admixture. This mixture can be made of recycled resin and recycled bitumen to provide the best possible resistance to water. However, before applying any kind of crystalline admixture, the area should be swept and vacuumed thoroughly to loosen any dirt, dust, and soil. Afterward, a fine-grit sandpaper should be used to polish the surface to create a non-scratchy finish.
There are two main types of crystalline coatings for waterproofing surfaces; primary coating and sub-slab membrane systems. A primary coating system involves spreading a thin layer of the coating material over the surface to form a protective film. For example, in case of a wet surface like a shower floor, the sub-slab membrane system would prevent water from seeping into the floor through the small gaps present in the surface.
On the other hand, a wall-mounted system would require a secondary, liquid-filled coating. This coating could either be applied directly on the foundation walls or be held within acrylic milieums that are suspended below the wall surface. The liquid-filled systems offer better image credit than the applied-on-the-wall systems because they eliminate the need to remove the top coating prior to application.
It is important to note that the two water-tightness systems discussed here differ from each other only by the method of application. In the case of primary-coated systems, the substrate is coated first with a rubber or PVC membrane. Subsequent coats are applied with acrylics, silicone, rubber, or other suitable emulsions. On the other hand, sub-slab-coated systems must be pre-coated with a rubber or PVC membrane and then penetrated with an emulsified solvent. Both processes allow for a more efficient waterproofing process because there are fewer barriers to prohibit liquids from penetrating.
There are many other forms of Waterproofing, including Bitumen Membrane Systems, Drywall Taping, and Engineered Wood Floor Waterproofing. These processes have different objectives, and the way they accomplish their goals may differ as well. In essence, however, all these forms of Waterproofing provide the same benefits: they help to prevent moisture from entering a space, they prevent the growth of mold and mildew, and they reduce the potential for structural failures. All these benefits translate into significant cost savings in the long run. So, if your property needs a fresh start, maybe it’s time to consider the advantages of Waterproofing.
