The rainy season often brings problems such as leaks and water seepage in buildings. If left unchecked, the walls can become damp, moldy, and even damage the building structure in the long run. Don’t want the walls of your home or office to be full of water stains and peeling paint? Well, waterproofing is important for maximum protection so that the building remains durable and comfortable to live in!
But, not all waterproofing is the same! There are various types of waterproofing that can be tailored to the needs and conditions of the building. For example, some are suitable for roofs, while others are more suitable for walls or bathroom floors. Don’t make the wrong choice, let’s get to know the kinds of waterproofing and their functions!
Types of Waterproofing for Buildings
Every building has different protection needs, depending on the location, environmental conditions, and how strong the resistance must be maintained. So, here are some of the most commonly used types of waterproofing.
1. Waterproofing Coating
This type works by being applied like paint, so it is very easy to apply without the need for special tools. Based on the basic ingredients, the waterproofing coating itself has several variants, namely:
Cement Base
Contains a mixture of cement and special liquid, suitable for areas that do not move much, such as balconies and toilets. Besides preventing moisture, cement base also makes the surface more resistant to water pressure.
Acrylic Base
The texture is thicker than regular paint and can be diluted using water. Acrylic base is more elastic than cement base, so it can adjust to temperature changes and small movements in the building.
Solvent Base (Polyurethane/PU)
Super elastic up to 600% and UV and puddle resistant. Usually used for areas that are frequently exposed to water, such as flat roofs and swimming pools.
2. Membrane Waterproofing
If you need extra protection for a large concrete roof, membrane waterproofing can be an option. It comes in sheets or rolls and there are two ways to install this type of waterproofing. How is it?
Torching Membrane
Installed by heating to make it stronger and more durable.
Cold Applied Membrane
Has its own adhesive, so it is more practical because it is simply taped without the need for heating.
Well, in terms of materials, polyester-based membranes are stronger and more durable, although they are slightly more expensive than those made from fiber.
3. Integral Waterproofing
This waterproofing is mixed directly into the concrete mix before casting. Suitable for those who want comprehensive protection from the start of construction. What are the advantages of this type?
Reduces water usage by up to 30% without reducing concrete strength
Increases concrete’s resistance to cracking and leakage
Makes the structure more durable in the long run
4. Crystallizing Waterproofing
This waterproofing works by actively reacting within the concrete. When applied, it forms permanent crystals that fill the pores of the concrete and strengthen its resistance to water. Therefore, this type is perfect for areas that are often exposed to high water pressure, such as basements and swimming pools.
5. Self Adhesive Flashband
For those of you looking for practical and easy-to-install waterproofing, self adhesive flashband is the solution! It comes in the form of a sheet with two layers, namely adhesive and leak-proof protection. This type of waterproofing is often used for roof repairs, gutters, and joints between construction materials.
If you use self adhesive flashband, you don’t need any additional tools, just stick it on and instantly protect from leaks!
So, choosing the right type of waterproofing is important to keep your building sturdy and leak-free in the long run. With the right protection, you don’t have to worry about damp walls, peeling paint, or even the structure of the building being damaged by water.
