Top Six Ways to Waterproof Concrete
Although concrete is a strong material, over time, it will suffer some erosion as it is exposed to the elements. Not only does it look bad, but it can compromise the structural integrity of a building. One of the best ways to protect the concrete is through waterproofing, and there are different options to choose from. You can use grout and epoxy, polyurea, crystalline waterproofing, and more. Take a look at the top six ways to waterproof concrete.
- Grout and Epoxy
One way to waterproof your concrete is with grout and epoxy. You will start by injecting them into any cracks, or you can drill holes into the surface to insert these materials. The grout will react with any water to form a sealant, resulting in a gel. The gel will turn the crack into a barrier that is resistant to water, and you can do this for tunnels, foundation walls, tanks, and piping.
- Polyurea Coating
Another material you can use to waterproof concrete is polyurea coating. This material is UV resistant, so it won’t suffer from sun damage. It won’t fade or change colour. It is a great option because it is also moisture-resistant. Concrete is a porous substance, so liquids can seep into the pores and cause the concrete to break down and crack over time. However, when you use polyurea to coat it, this won’t happen. This coating is also resistant to staining and other chemicals and is easy to clean.
- Crystalline Waterproofing
Crystalline waterproofing is a process that causes the ingredients in crystalline products to react with free lime and moisture in concrete then it forms crystals in the capillary system of your concrete. When you choose this process, you can use the crystalline to fill any area inside the concrete, including capillaries, cracks, and pores. No water will be able to enter the concrete. The crystalline actually causes the concrete itself to become a waterproof barrier.
- Bituminous Waterproofing
Another option is to use bituminous waterproofing for concrete foundations. It uses bitumen, which is asphalt. This sticky liquid, a semi-solid form of petroleum, has a high viscosity. You can use it to ensure that concrete is waterproof. It can be found in membrane roles that will bond to the surface. It can also be poured over the concrete, or you can use self-adhesive tape. This material will make the concrete waterproof without causing cracks or compromising the structure.
- Vinyl Ester Resins
Vinyl ester resins are a cross between epoxy resins and polyester resins. When these two materials are combined, the resulting mixture is not only waterproof, but it also offers resistance to corrosion and has better durability and longevity. In addition to water, this material protects concrete from a wide range of temperature changes and can stand up to exposure to certain chemicals as well.
- Polyurethane Liquid
Another option is polyurethane liquid. This is a membrane that is often used on roofs and doesn’t impact the moisture levels of the concrete. Water often finds its way into concrete, and it is important to find a substance that gives you lasting waterproof protection. Polyurethane waterproofing is made up of two components, a base of polyol and a reactor of isocyanide. They combine in a specific ratio to create a liquid coating that waterproofs the concrete. It is easy to install and can be applied quickly. You can also use it after construction, so it isn’t limited. In addition to being waterproof, it is resistant to UV damage, acids, fuels, and alkaline cleaners. It has strong adhesion properties, making it a great option when you need to fill cracks and ensure that concrete is waterproof.
