Hear the words "injection waterproofing" and feel a little lost? It's understandable—the process can sound intimidating, but it's actually relatively simple. Injection waterproofing is an effective water control system that works by permanently filling and sealing leaky cracks in a structure, usually concrete or brick.
Using injection waterproofing can save you time, money, and a lot of frustration in the long run. Cracks are common in both older buildings and those newly built, so understanding the fundamentals of injection waterproofing is essential for preventing costly water damage.
In this article, we'll lay out the basics of injection waterproofing, what it is, how it works, and why you may need to use it. By the time you finish reading this piece, you'll have a much better understanding of injection waterproofing—as well as peace of mind to know your property is being kept safe from water infiltration.
What Is Injection Waterproofing?
If your home is going to last a lifetime, you'll need to take the right measures to protect it. One of the best and most effective ways of doing that is with injection waterproofing. But before you can understand this concept and decide whether it's the right fit for your home, you first need to know what injection waterproofing is and why it's useful.
Injection waterproofing—sometimes called wall waterproofing—is the process of injecting a proprietary waterproof-forming foam into walls. This foam expands within seconds to seal cracks, protect against water damage and stabilize the walls against shifting or settling. Injection waterproofing is also great for filling voids in concrete foundations caused by age or settlement movement, making sure there are no channels for water seepage.
Because it works on both exterior and interior surfaces of a home, injection waterproofing is an incredibly versatile solution for any weather conditions or type of terrain. It's also minimally invasive; all that's required is a series of small holes in walls which are quickly filled with the waterproof forming foam. So if you're ready to invest in long-lasting protection against water damage and erosion, injection waterproofing should be your go-to solution!
Benefits of Injection Waterproofing
Injection waterproofing is a reliable and cost-effective way to strengthen and protect your home or commercial property from the damaging effects of water. It effectively seals any existing leaks or cracks, preventing water from entering into the building and causing further damage.
Injection waterproofing has many benefits, including:
Increased longevity of surfaces: Injection waterproofing prevents further damage caused by water, ensuring that the surfaces can last for a longer period of time.
Reduced maintenance cost: Injection waterproofing can save you from having to constantly repair the damaged surfaces, saving you money in the long run.
Improved safety: By preventing further water damage, injection waterproofing can help keep your home or building safe and secure.
Enhanced structural integrity: With injection waterproofing applied to your home or business, you can rest assured knowing that its structure is reinforced with reliable protection against water infiltration.
In addition, injection waterproofing does not involve any complex procedures—it is an easy process that produces lasting results with minimal effort.
How Does Injection Waterproofing Work?
As you may already know, injection waterproofing is a great way to protect your structures from water damage. But do you know how it works?
Injection waterproofing is a process where a waterproof cementitious grout is injected into walls, floors, and ceilings. This material fills up any cracks and pores that could let water in and forms a barrier to keep out moisture. It’s also designed to be flexible enough to move with the structure when it shifts or experiences temperature changes.
The installation of injection waterproofing usually consists of three steps:
Preparing the surface: This involves cleaning the area and using compressed air or chemical cleaners to open up any existing pores or cracks.
Applying the grout: The next step is to apply the grout which will form a waterproof barrier against moisture. The grout needs to be applied carefully, ensuring that it makes its way into any possible entry points for water.
Finishing touches: After applying the grout, you may have to make some adjustments like adding additional drainage methods around the structure or sealants for additional protection from water damage.
Injection waterproofing can be an effective solution for keeping moisture out as long as it’s properly installed by experts who understand its complexities!
Types of Materials Used in Injection Waterproofing
Injection waterproofing works with a combination of materials. Depending on the application, different materials may be used to create a watertight boundary around a structure. Some of the most common materials used in injection waterproofing are bentonite, epoxy resins, acrylics, and urethanes.
Bentonite
Bentonite is a type of clay composed of aged volcanic ash that forms an impermeable seal when combined with water. It is an ideal material for injection waterproofing as it swells up to 15 times its dry size when exposed to water. When injected into cracks or joints in a structure, it's able to seal them up completely and prevent any possible seepage.
Epoxy Resins
Epoxy resins are another popular option for injection waterproofing as they have high adhesion properties that allow them to bond with concrete quickly and effectively. They also retain their flexibility so they won’t crack when the structure moves over time due to thermal changes or vibrations.
Acrylics
Acrylics are another type of material commonly used in injection waterproofing as they remain flexible even in cold temperatures and can easily bridge small gaps or cracks in a structure. They provide an effective barrier against moisture which makes them valuable for both interior and exterior applications.
Urethanes
Urethanes are another type of material commonly found in injection waterproofing because they can expand up to 400% in volume and tightly seal off any cracks or voids present in a structure. They also have excellent adhesion properties which allow them to bond with concrete and provide long-lasting protection against water seepage.
Identifying and Repairing Leaks Before Injection Waterproofing
One of the first things you have to do before you inject waterproofing is to identify and repair any existing water leaks. Injection waterproofing is designed to stop incoming water, but it won't be able to handle an existing leak and not all leaks are visible.
To locate a leak, it's important to understand the materials that are prone to leaking water:
- Foundations walls
- Basement slabs
- Concrete floors or walls
- Pipes, tanks, and other equipment with concrete encasements
You can use specialized equipment such as electronic moisture meters, thermal imaging cameras, and dye testing kits to detect hidden water leaks. Once you've identified the source of the water leak, you can take steps to repair it before injecting waterproofing. This could mean filling cracks or patching up concrete joints and surfaces with a cementitious mixture or plugging gaps in concrete walls with epoxy resin injections.
Injection waterproofing alone can't fix existing water issues—that's why it's so important to make sure you check for any existing problems before improving your building's waterproofing system.
Costs Associated With Injection Waterproofing
Injection waterproofing isn't without its costs, however. Depending on the size of the project and the type of materials you use, costs can vary significantly. It's always a good idea to get multiple quotes from reputable contractors for comparison before choosing one.
When budgeting for injection waterproofing, here are some things to consider:
Labor costs: Injection waterproofing requires an experienced contractor who is familiar with the process and knows how to use the right materials. This will make up a large portion of your total cost.
Materials: Depending on the area that needs injection waterproofing, you will need to buy some specialized materials from a distributor. This could include specialized epoxy and grouts as well as pumps and drilling equipment.
Other costs: You may need additional items such as scaffolding for hard-to-reach areas or protective membranes to keep dirt away from hazardous areas during installation. These are not always necessary, but it’s something to think about when budgeting for injection waterproofing.
Overall, injection waterproofing is an effective way to protect your building from water damage—but it comes with a price tag attached, so make sure you do your research before committing to any project!
