Every building, suspension bridge, sidewalks, and train rails have this section which is intentionally left on purpose during its construction. When dealing with concrete or iron, there is a process of contraction and expansion of the material due to change in temperature. Due to this phenomenon, the entire structural integrity experience a force within its structure and if there is no exit point or leverage area for the force to exerts, it will cause a chain reaction around the structure and will result in flaking and breakage. Based on the this scenario, every building and large structure needs expansion joint which are usually located at the most critical area, such as in roof and outer zones. Placing the expansion joint is somewhat a permanent method that ensures that all contraction and expansion caused by thermal change can be easily controlled, which leaves us to next question. Is it really fine for us to endure an awfully large opening in the mercy of rain and other water source. A simply answer to this is no way. And where we look into a separate solution known as expansion joint treatment provided to us by waterproofing experts.
Need for expansion joint in building
Talking about buildings, these large structural facilities composed of concrete, reinforced concrete and structural iron and brick work. Along with masonry works, the structure is usually designed using shock proof material to withstand minor shocks from earthquakes. The construction is heavy focused on concrete, and as we understand through science and research, concrete absorb heat and result of it, expansion takes place to mm length. Although the expansion cannot be seen through a naked eye, this expansion is enough to disorient itself from the structure formation and cause cracks, flaking and at worst case, the concrete simply dislocates all of a sudden. Good material can withstand these minor contraction to a certain level, but still, contraction and expansion take place nonetheless. Through the use of expansion joint, these contraction and expansion are controlled in building hence the need for it.
Limitation of construction specialist
During construction works, the specialist will suggest and create an expansion joint in buildings and will ensure that perfection is achieved since its an important element for large construction. While doing this, a construction specialist and planner will take everything in accounts such as the quality of material, the expansion size, the thermal threshold of the material and a lot of other technical stuff. While keeping this in evaluation, there is some limitation where the construction specialist could not go over it. Considering for more micro understanding of expansion joint, he will overturn the need to close down the expansion joint using waterproofing products. This domain is out of the scope for construction and development. Which means the specialist for waterproofing related job are separate and they should handle this typical situation.
Sealant vs membrane
Once we have made up our mind, the next thing that comes into our minds is which waterproofing product should go with for expansion joint treatment. Indeed there are several options at our disposal but out of all the potential choice, we have two of the most preferred type of waterproofing solutions that leads all the way. Sealant and membrane are among the widely used waterproofing products we can use to ensure that expansion joints are properly closed down for any expected water-based damages. There is up to the expert or contractor to choose anyone. But there is a substantial difference between the two. A sealant is a liquid form, which is usually the best choice for small expansion joints. A sealant takes less time to apply and will work as a transparent agent. While the membrane is in reality bitumen sheets which comes in various width. For expansion joint treatment, the membrane is a choice when the width of the expansion joint is large and fills a bigger space. Expertise is required to apply membrane over an expansion joint, while sealant is almost DIY based.
Other Waterproofing options
In the world of waterproofing, we have other options as well, such as acrylic based chemical, liquid bitumen, cementitious coating, CBR based chemical and a lot more. All of these products have a great water-resistance value which can ensure that the proper system is maintained to withstand the unnecessary water to flow inside of expansion joint section. Since most of these products come in liquid form, there is somewhat restriction to apply these regarding expansion joint treatment is considered. The main reason behind this restriction is because we are required to close the expansion joint from the top, but when liquid is poured all the way, this will pose a negative threat towards the actual intention of expansion joint treatment. We usually abstain from using the liquid form of waterproofing product if an expansion joint section is large.
What effect does Expansion Joint Treatment in Karachi over your structure?
Many people understand the urgency to close the expansion joints as soon as possible, because the wrath of water-based damage when it gets inside the expansion, we’ll be in hot waters.
The only solution to prevent such catastrophic damage is through the application of expansion joint treatment in Karachi.
Let’s learn in-depth what effects does expansion joint treatment in Karachi will pave through our structure when availed.
Improves the structure of life
The main concern of water-based damages that pave ways to damage structural elements over any facility through which the entire construction site is designed.
Water-damages the concrete structure to a greater degree and its very much needed to clampdown on the source. If your expansion joint is open at the mercy of open weather, you’ll find a very little window of opportunity to secure your structure for several years.
The best course of action for this regard is to vail the solution of expansion joint treatment in Karachi because that’s what makes sure to secure water-related damages for several years.
Secure from mold and mildew elements
Whether the quantity of water is low or high, at the side of your expansion joint will open a way for water to get stored within the columns.
After some time, the mold and mildew will start to appear on an unprecedented scale because the water that’s being stored from the external end will produce several seepage spots. And then paved the way of mold from different areas.
All of this can be fixed for the better through availing expansion joint treatment in Karachi’s solution as soon as possible.
Security from smell
With water leakage, the smell element is also an issue that should be resolved sooner rather than later. Only by the application of expansion joint treatment in Karachi, we can ensure that water resistivity is obtained.
No matter if its raining or water being leaked through any other source, the issue of smell will come when water is mixed with garbage.
No one knows in the truth about the stench observed through water leakage, but either way, it’s vital to close down your building’s expansion joint.
Extremely effective during monsoon season
We can’t emphasize enough on the importance of expansion joint treatment in Karachi during the monsoon season. When water goes down in the form of pouring into your building, the damage comes like unending waves.
More than leakage and seepage, it can also be a source of pest infestation in the long run which is devastating.
Why we use waterproofing product to achieve expansion joint treatment in the first place? It’s a simple answer, that is to resist leakage and seepage and another sort of water-based damages. Once the water is poured down the expansion joint, various types of pests are also produced, which is not a good thing at all. There is indeed a huge prospect for using waterproofing based products and ensure a clean and protected building for customers.
