What Is The Process For Applying A Damp-Proof membrane On A Concrete Floor

1. What Is The Process For Applying A Damp-Proof Membrane On A Concrete Floor? Over the years, concrete has become one of the most reliable construction materials. As trends keep changing, we cover it up with paint, wallpaper, and facades. However, recently the rustic and raw look of concrete has been becoming popular. As such, it is now becoming a common flooring option around the world. One of the key ways people achieve this is by using floor screed. It is a type of self-leveling concrete mix. It makes for a wonderful flooring option. However, it is necessary to get a damp-proof floor membrane on concrete. Otherwise, you risk water damage in your home. Moreover, these DPMs ensure the longevity and durability of your concrete floor too. Getting a DPM not only protects against moisture but also strengthens the structure against damage caused by dampness. In this comprehensive guide, we’ll dive into the complex process of applying a damp-proof floor membrane on concrete. Understanding Damp Proof Membranes A damp-roof membrane or a DPM is in essence a barrier that keeps moisture from seeping through the concrete floor. Without a DPM, you’ll be repairing and replacing your floor far too often. This is especially true during wet seasons such as monsoons and snowy winters. The water-proof floor membrane on concrete that you use before the floor screed will keep moisture at bay. It is made of materials such as bitumen. These materials help ensure the layer is impermeable and will thus protect the floor. This is true for both ground moisture and rising dampness. Additionally, it will also protect your floors in case of water ingress. Step-by-Step Guide to Applying DPM on Concrete Floors The above explains the benefits of using a protective layer on a concrete floor. Moreover, we’ve explored how it works to protect your floors and keep the floor durable for a long time. However, it is time for us to learn about the process. Understanding the process will help you make informed decisions for your property. 1- Prepare the Surface Preparation is key to achieving perfection in any task. This is true enough for installing a damp-proof membrane. Before applying the waterproof membrane, it is necessary to put some work into the base as well. For an effective layer, the concrete floor must be clean and dry. Furthermore, it should not have any debris or other contaminants. Additionally, make sure you fix any cracks or uneven surfaces on the floor. Such imperfection can compromise the quality of the protective layer.

2. 2- Selecting the Right DPM for Your Floor In addition to the above, it is equally important to choose the right damp-proof membrane for your floor. It should be suitable and you should consider key factors while making a choice. ●The first thing you must consider is how you’re going to use the floor. Commercial spaces have more foot traffic than residential places. As such, consider how you expect to use your floor. ● Secondly, consider the location of the floor screed. Additionally, consider how much moisture the floor will have to deal with in said location. ● Finally, some specific requirements also come into play. For instance, choosing between liquid-applied membrane vs. sheet membrane. You might also choose from a combination of both. It is best to consult professionals in this as the impact of a wrong decision can be quite expensive and inconvenient. Moreover, most experts will recommend using both liquid- applied and sheet membranes for long-term protection. 3- Application of DPM Looking at the application of the floor membrane on concrete, we need to consider the type of membrane too. The methods vary for both types so we should look at them separately. Let’s begin with the sheet membrane and then look at the liquid-applied membrane process. ● To install a sheet membrane, you will first need sheets of the material. It should be cut to the size of your floor and then you can lay it onto the concrete floor. Make sure the membrane overlaps perfectly. Additionally, seal the seams and ensure you don’t miss a spot. This step is to maintain the integrity of the membrane after you’re done. ● This method is a little more complex and needs a professional hand to do so perfectly. First, you apply the liquid prospective membrane directly on the concrete floor. Then you need to cure it. Further, the finer details of the application will depend on the sheets you’re using. In any case, stick to manufacturers' instructions to achieve the best results. They offer recommendations on the best thickness and ideal drying times. That’s the basis of the application process. After this comes curing and drying, then you can proceed with the screeding. Let’s take a look at that as well before we move on. 4- Curing and Drying Time for the Membrane After you’re done applying the damp-proof membrane you should allow it to dry for the appropriate time. If you screed the floor too soon, the protective layer may lose some of its efficiency. The perfect drying time depends on the conditions of the floor, the weather, and the area. With all these factors in an ideal state, it will dry within 6 hours. However, if the conditions are damp, it may even take about 48 hours. To touch though, it will be dry within an hour. As such, you need to be extra careful and follow the manufacturer's instructions instead of relying on touch.

3. The Importance of Damp-Proof Membrance in Floor Screeding Adding a laying of damp-proof membrane before screeding the floor will give you many advantages. To begin with, moisture can be very damaging to the floors and walls of your home. It can compromise the integrity of the screed. This can lead to mould or mildew forming. As you can imagine, this is a recipe for various health issues. Other than protecting you from these, the membrane can also act as thermal insulation. Conclusion Applying a DPM on a concrete floor before you screed is a crucial step to protect the structural integrity of the floor. Moreover, when you follow the steps above, you can ensure a strong and unshakeable foundation. For a high-quality floor screen, check out Pro-Mix Concrete.
