But calm down, you don’t need to immediately dismantle the entire concrete foundation! There is a way to patch a concrete foundation from the bottom that is practical without being complicated. With the right method, you can solve this problem more easily and still effectively. Let’s take a look at the steps to make your home safe and comfortable again!
Preparation Before Patching Concrete Dak
Before starting the repair, it is better to prepare a few things first so that the results are maximized. Careful preparation will make the patching process smoother and the leak can be resolved more effectively. Let’s check the steps!
1. Find the Leakage Point
The first step is to find the source of the leak in the concrete foundation. Usually, leaks occur in areas where there are cracks or small gaps. The easiest way is to check it when it rains or pour water on the concrete deck to see the seeping part. If you find it, mark the area to make the repair process easier.
Don’t take small cracks lightly! Although they may seem trivial, these cracks can cause more severe leaks in the future.
2.Clean the Concrete Surface
Now it’s time to clean up! Make sure the area to be patched is free of dust, dirt, or grease that could interfere with the adhesion of the patch material.
Use a wire brush or clean rag to scrub the concrete surface. If necessary, dampen it slightly with water, then let it dry before moving on to the next step. A clean surface makes the patch stronger and more durable.
How to Patch a Concrete Dak from the Bottom
Once all the preparation is done, it’s time to get to the main part, patching a leaking concrete slab! Relax, the process is not as difficult as you might think. Follow these tips on how to patch a concrete foundation from the bottom for maximum and long-lasting results!
1. Use Special Patching Materials
For a strong and durable patch, use special patching materials for concrete, such as epoxy resin or instant mortar. These products have high adhesion and retain water well, so leaks won’t easily return.
Apply the crack sealing material using a spatula or similar tool. Make sure the material is completely inserted into the crack for maximum protection. After that, let it sit until it dries according to the instructions on the package.
2. Cover with Waterproofing
Once the patch is dry, don’t forget to apply a layer of waterproofing! This is very important to prevent leaks from coming back in the future.
You can use elastomeric or bitumen-based waterproofing, both of which have a high resistance to water. Estop’s bitumen-based waterproofing materials are Estoflex GP and Estoflex PU850. Make sure the coating is evenly distributed and covers all the patched areas, for maximum protection.
Well, that’s how to patch concrete walls from below that you can try yourself at home. With the right steps, leaks can be resolved without having to dismantle the entire concrete deck. The important thing is to make sure you find the leakage point correctly, clean the surface before patching, and use the appropriate material so that the results are durable.
For maximum results, use a quality patching material like Estopatch MP. This product is specially designed for concrete repair and has high adhesion so it can be a powerful solution to concrete cracks under the concrete deck.
