Here’s the Best Waterproofing for Concrete Roof in Singapore
In this section, you’ll learn about the four finest methods that work well to waterproof concrete roofs in SG. Here’s the details:
Cementitious Membrane
The cementitious membrane is a trendy pick for waterproofing concrete roofs. It also works well if you use a mixture of cement and acrylic materials on your roof. And, this helps keep water out and ensures the spot stays dry.
Most people love this method for its affordable price range and easy to apply. However, it can have some bad sides too. Since it is made from cement, it can crack over time.
And, this is only because cement isn’t very flexible. Besides, the roofs often expand and contract with temperature changes that cause cement material to tear easily. So, this is usually best for flat roofs made out of concrete or interior areas with less activity.
Sheet Membrane
The sheet membrane is a reliable option for waterproofing concrete roofs. It is mostly made from rubberized asphalt that sticks by itself. Thanks to its adhesive part, you can get a great benefit from that which is the consistent thickness.
And, this simple thickness helps a lot to ensure coverage and protection against water damage. Even if it has many pros, there are some drawbacks too. Most of the time, this kind of membrane costs a lot more than liquid or wet options.
Not only is the material more costly per square foot, but the installation process is more complex. Therefore, you’ll need to cut, handle, and secure the sheets. This can also add to the overall labor cost.
Liquid Applied Membrane (LAM)
Liquid Applied Membrane (LAM) is a top choice for waterproofing tiled or concrete roofs. One of the biggest plus points of LAM is its ability to cover every part of your roof. It also ensures to leave not a single space that can cause future leaks.
Plus, as it’s a liquid solution, it is pretty easy to apply and spreads easily. And, you can create a smooth and joint-free layer that keeps water out.
This method is also effective in stopping water from seeping through the corners or gaps unlike some other methods like sheets or rolls.
However, it’s vital to have an expert help to handle the application. If the layer is too thin, it can tear or get damaged. This can also ruin the sealed area.
Besides that, the application process is quick thanks to the Cold Spray Application technique. Most experts can also cover large areas up to three times faster than other methods. And, this makes it a great option for waterproofing your roof.
Bituminous Coating Waterproofing
Bituminous coating waterproofing (also known as asphalt coating) is another popular method for leak proofing concrete roofs. It usually uses bitumen which is a substance derived from crude oil. Thanks to its usage, the solution is mixed with mineral spirits or naphtha.
To make the coating more flexible and tough, it’s often altered with polymers like polyurethane or acrylic. And, one of the main reasons people pick this method is its strong resistance to UV rays and corrosion. This also makes it useful to ensure the coating lasts longer.
However, a hitch that bituminous coatings may show harms the climate. To solve this issue, you can go with items that are made out of crude oil and safe to use without harming the environment.
Despite all this, its toughness and high resistance make this kind of coating solution a solid choice for waterproofing needs.
