The chimney, like any other part of the home, can have problems and defects which make it less efficient and safe to use. One of the most common chimney ailments homeowners run into are cracked flue tiles. When left untreated, this issue can wreak havoc on the home’s chimney system. Cracked tiles can lead to dangerous gas leakage allowing carbon monoxide to seep into the home’s interior. It can also allow deadly heat transfer to combustible materials in the surrounding areas increasing the risk of home fire.
The following email was sent to me as an attachment to an email hiring me as a phase inspector for this gentlemans new home. Hi xxxxx and yyyyy, I was disappointed to find a large, deep crack in my basement floor when I stopped by to see the house over the weekend. It runs more than halfway across the basement floor, and appears to be full thickness. I am concerned because not only is it. Basement cracks are entirely normal, though they can cause a lot of problems for homeowners. Shrinking concrete places a vast amount of stress on a basement wall, resulting in cracks. While you can't prevent your basement walls from shrinking, you can fill cracks before water is allowed to seep inside of your home. A cracked basement floor.
Why It Happens
Cracked tiles often occur when heat is not evenly disbursed throughout the chimney. This leads to unequal expansion of the tiles causing them to buckle, crack, or split. Clay tiles are most prone to this problem because the material is unable to quickly absorb the heat.
How to Fix It
When cracked tiles are found, the best way to remedy the situation is by lining or relining the chimney itself. A stainless steel chimney liner is the preferred option among homeowners as it often comes with a lifetime warranty and typically never needs to be replaced. Single clay flue tiles can also be installed to replace broken ones but will often crack again creating another safety hazard within the flue. If damage is minimal, a product such as HeatShield® Cerfactory Flue Sealant can be used to fill the cracks. A new liner though will offer the best protection while providing a more permanent solution.
Regardless of how you choose to address a cracked tile problem, hiring a professional sweep to do the work is important. They have the expertise and knowledge to complete the often complex lining process while also ensuring the chimney is compliant with local fire codes.

- The 5 Best Basement Wall Crack Repair Kit
Basement wall cracks are caused by various reasons, including mistakes in pouring or mixing concrete, shifting foundation, and leaks. Fortunately, basement wall cracking isn’t difficult to address because there are many repair kits available on the market.
- If you're dealing with a full basement, start by patching cracks in the foundation and sealing basement walls. Use a polyurethane masonry caulk like Sikaflex ($7 per tube) or UGL's Masonry Crack Filler (about $5 per tube). For 1/4-inch or larger cracks, use hydraulic cement, which expands as it dries.
- Emecole DIY Leaking Basement Wall Crack Repair Kit. If you are looking for a kit that has everything.
The best way to repair cracks in concrete basement walls is by injecting them from the inside. Repair is often quick and inexpensive. The process only involves polyurethane or epoxy injected into the cracks.
We’ve listed the best basement wall crack repair kits below to help you make an informed buying decision. Check them out!
The 5 Best Basement Wall Crack Repair Kit
1. Emecole DIY Leaking Basement Wall Crack Repair Kit
If you are looking for a kit that has everything you need, then this may be the one for you. The star of the show is the formula, which the company calls it the Emecole Metro 102 Premium Polyurethane.
The formula is specially designed for foundational walls. Hence, it is strong enough to be used for any concrete crack. Aside from that, it prevents water from entering when fully cured. In fact, you can even use it to seal swimming pool cracks.
The Emecole Metro 102 Premium Polyurethane expands 20 times its original volume. Thus, you can sure it will fill all the interior cracks. Once it’s cured, it can expand and contract together with the concrete. This unique attribute is especially desirable if the concrete is subjected to freezing and thawing cycles.
The kit includes enough formula to repair approximately 30 feet of crack. Also, it’s easy to handle because of its low viscosity. The package also includes a caulk gun, which is very important for the application of the formula.
Perhaps the only downside with this kit is the price. It’s a bit on the expensive side. However, you will still be getting your money’s worth knowing it works very well, and it is easy to use.
Pros
- Very Thorough Kit – you probably don’t need anything else aside from what’s included in the kit.
- Emecole Metro 102 Premium Polyurethane – a very well-engineered formula.
- Experienced – the company has been around since 1987 and considered to be pioneers in the field.
Cons
- A bit expensive
2. RadonSeal Concrete Foundation Crack Repair Kit
This crack repair kit has a trick under its sleeve. For now, it’s good to know that with this kit, there’s no need to do drillings to repair a concrete crack. You only need the kit’s polyurethane formula that comes into two components.
There’s enough product to cover about 10 feet of crack. It’s worth pointing out that the formula is low-viscosity. This means it’s easier to manage and inject. And most importantly, it can easily penetrate voids, making it suitable for repairing hairline cracks. The product also bonds tenaciously to concrete, whether it is dry or wet.
However, it’s still flexible enough to allow the natural movements of the concrete. One of the best things about this kit is that the formula can block radon, a radioactive gas that’s classified as carcinogenic. Since it can block radon, it also naturally blocks soil, water, and vapors.
The price is also very affordable, which makes it an excellent choice if the budget is a bit tight. Since this kit is affordable, then you can’t really expect that it will include a caulk gun. Perhaps the only downside is that the formula can only cover 10 feet of crack.
Pros
- Budget-friendly – it’s a very affordable crack repair kit
- Low- pressure formula – there’s no need to use specialized equipment to inject the product.
- Excellent barrier – blocks soil, water, vapor, and even radon
Cons
- Can only repair 10 feet of cracks
3. Applied Technologies Concrete Foundation Crack Leak Repair Kit
While there’s nothing unique about this crack repair kit, it’s priced so well that it is hard to ignore. First of all, this kit is good at repairing concrete cracks. However, the formula is good enough for cracks in the foundation wall too. As a bonus, it also blocks the water in case the crack comes with a leaking. The formula can repair about 20 feet of cracks.
While it doesn’t provide the most amount of coverage, it also doesn’t offer the least. The name of the formula used in the kit is Hydra Stop 300. It is a non-shrinking urethane foam. You don’t want a formula that shrinks as that would open up leaks that may compromise the integrity of the wall.
Despite that, the foam is still flexible, and does not hinder the natural movements of the concrete. Another thing that’s worth mentioning is that the package includes a very detailed step-by-step guide. If you’re handy enough, you probably don’t need to hire anyone if you follow the comprehensive guide.
Also, the kit includes a caulking gun. It’s a convenient package, so you don’t have to go shopping for a gun, and worrying if it will fit with the product’s bottles. When talking about downsides, there are not a lot of glaring issues with the package. The kit is priced just right when considering what it includes. Perhaps if there’s a downside, then it is just a “jack of all trades, master of none” type of kit.
Pros
- Good value – the price is just right, and it includes a caulking gun.
- Non-shrinking formula – doesn’t compromise the integrity of the wall.
- Easy-to-follow guide – it includes a detailed step-by-step guide.
Cons
- Jack of all trades master of none
4. Mar Flex Concrete Crack Repair Kit
This one is another budget-friendly entry to the list. It’s a crack repair system that’s designed for poured wall construction. Considering how affordable it is, it’s got most of everything you need to repair a concrete wall crack. The kit includes two jars of Crack and Seal Port Adhesive. Furthermore, the package has 15 surface ports. Assuming that you will be spacing the surface ports at 10 inches apart, you should be able to cover around 12 feet of crack.
The injected formula is made of polyurethane. It’s pretty much the standard for crack injection repair systems as it’s quick to dry. Also, it does not impede the natural expansion and contraction of the concrete.
Another thing that’s worth mentioning with this kit is that it comes with an instructional CD. It’s a quick “how-to” guide to help you with the process if you want to go with the DIY route. The guide is in English and Spanish.
Coming at a very affordable price point, it’s hard to point out glaring issues with this kit. Perhaps you could say that the surface ports only covering 12 feet of crack may be an issue.
Pros
- Budget-friendly – one of the most affordable kits in this list.
- Polyurethane – standard for crack injection repair due to its quick-dry and concrete-bonding attribute.
- Instructional CD – available in English and Spanish.
Cons
- Surface ports only cover about 12 feet
5. Flexomeric Concrete Foundation Crack Repair Kit
This kit is among the few that include a caulk gun. Well, it should be included because the formula that the package uses requires dual injections, which requires a tool that’s a bit specialized.
The kit is also designed to stop or prevent water leaks. However, it can be used for both dry and wet cracks. The formula is also excellent as it can expand 400% to 600% its original volume when fully cured. This is the reason why it does an excellent job at plugging water leaks.
Despite being air-tight, the formula remains flexible. It can adjust with the concrete shifting due to thermal cycles. Also, the kit is designed to repair cracks that are 1/16” to 5/16”. If there’s a downside to this kit, then it has to be the formula.
As mentioned above, you will need a dual cartridge gun. On the upside, there’s already a gun in the kit.
Pros
- Stops water leaks – the formula is specially designed to stop or prevent leaking water.
- Flexible – the formula remains flexible to accommodate concrete shifting.
- Includes a caulk gun – no need to make a separate purchase.
Cons
- The formula needs a dual injection gun.
Types of Basement Wall Cracks
Knowing the kind of cracks you have in your basement walls will help you determine the severity of damage that your home has sustained. However, you should keep in mind that any cracking you discover, especially in the foundation of your home, must be taken seriously. Inspect cracks closely and repair them to protect your home and ensure structural integrity.
- Structural Cracks
Structural cracks are the most serious, so if you see them, you have to act as soon as possible as the cracks pose risks to your home’s structural integrity.
A sure sign of a deficiency is a crack that is ¼-inch wide or more. A structural crack in a basement wall is typically due to movement, whether it is from soil shrinkage, soil pressure or temperature changes.
If you spot moisture or water coming from structural cracks, the quicker you repair them, the better. Quickly changing patterns of local climates can cause cracks to worsen or lead to even more water and moisture issues.
- Non-Structural Cracks
A non-structural crack in basement walls doesn’t pose any threat to a home’s structure, and it usually results in leaking only when the snow melts or during rainstorms. Although there is no structural threat with this kind of basement wall crack, water that’s seeping into the basement is a matter that requires attention and has to be taken seriously.
Water leaking into a basement can ruin belongings, floors, walls, and contribute to the development of mold and mildew. When left unattended, non-structural basement wall cracks may get worse as well. This is why homeowners are advised to act fast in addressing cracks, no matter how small or insignificant they may seem. Don’t wait until water has seeped into your interior before you fix the issue.
Take note: Basement walls made of concrete often have minute cosmetic cracks which are normal from concrete’s natural curing process. With cracks that are between one to two millimeters each and run diagonally or vertically, they may be non-structural.
- Horizontal Cracks
Horizontal cracks are the ones you need to watch out for because they signal serious damage to the structural integrity and foundation of a home.
While they’re seen in homes that have poured concrete foundations, they’re more commonly found in homes with brick or block foundations. Several things cause this kind of foundation damage, such as hydrostatic pressure that makes a basement wall to bow and soil pressure outside the foundation.
If you notice horizontal cracks, it’s important to repair the basement walls as quickly as possible before your home’s structural integrity is compromised. This kind of cracking can require extensive repair to secure the foundation and prevent it from causing any further damage.
- Vertical Cracks
Vertical cracks, in general, are the least severe and most common cracks you’re likely to encounter. They go all the way up or down or slightly diagonally, within 30-75 degrees vertical. They’re common occurrences in houses and usually result from foundation settling.
It is, therefore, not uncommon for a new house to have vertical cracks as the foundation of a home can settle greatly within the first year. Fortunately, vertical cracks are the least expensive and the easiest to seal. However, you should repair them immediately as they can grow or open even more.
- Diagonal Cracks
Cracks that are diagonal run along basement walls at a 30 to 75-degree angle. A thin, hairline diagonal crack is usually wide at one end compared to the other. A diagonal basement wall crack is often caused by “differential settlement.” In this case, one side of the foundation of a home settles lower than the other parts.
This uneven tension causes the diagonal cracking and happens because they house has been built on uneven ground or slope. It may also because of the contraction or expansion of soil under a certain portion of a house.
This kind of cracking can be sealed but the reason for the differential settlement has to be addressed. The solution can be the installation of new gutters which redirects rainwater away from your property, especially from an area that gets flooded regularly and causes the soil under one portion of your home to shift.
Basement Wall Crack Repair Methods
As you may already know, there are two different methods for repairing basement wall cracks: polyurethane foam and epoxy injection. Read on to know the difference between the two.
Polyurethane Foam Injection
Urethanes react with water and moisture in basement wall cracks to foam and then expand inside the walls. Polyurethane foam injection fills the void all the way, top to bottom.
The Basement Collection Crack Filler
As a matter of fact, urethanes expand as much as 30 times their initial volume. The foams are flexible, plus they move with contraction and expansion in basement walls from thaw/freeze cycles.
Additionally, less resin is required with urethane foams as they can expand in volume. This makes them a more economical choice than epoxies. Lastly, urethane injection is easier to do compared to epoxy injection.
Pros
- Easier to use
- Less expensive
- Flexible
- Fills wider cracks
Cons
- Not for structural repair
Epoxy Injection
Epoxies weld basement wall cracks together and they can restore structural strength. The strength of the bond is a lot higher than concrete, and movement is eliminated within a concrete basement wall during contraction and expansion cycles.
Home foundations that have a continuous stress load in them or are constantly moving may require additional repair methods to stabilize basement walls and prevent further damage. Epoxy is a lot stronger compared to concrete, but continuous stress load can cause walls to crack again.
Pros
- Stronger than concrete
- Offers structural repair
- High strength weld
Cons
- More expensive compared to urethanes
- Concrete can re-crack if walls are still moving
- Bond strength is less when done in wet basement wall cracks
How to Fix a Leaking Crack in Basement Wall?
While concrete port walls are reasonably strong and durable, there are instances that cracks can arise.Cracks can happen, whether the wall is textured or non-textured. Also, the wall can be classified into structural, non-structural, dry, or wet and leaking. No matter the classification, the process of repairing the crack is the same whether you are using epoxy or urethane foam.
Repairing a crack is a multi-step procedure. Each step must be done correctly to ensure the structured of the wall won’t be compromised any further.
Basic Overview
Before we cover the steps, it’s best that you know the fundamental idea behind this repair guide.
A visible crack in the wall is just the tip of the iceberg. Inside the crack could be a network of more cracks. In other words, you can’t just cover the crack with a seal of some sort. You need to fill up the void created by the crack to plug possible leaks and minimize structural compromise.
The most common products to fill-up the crack are epoxy and urethane foam. However, you can’t just inject these products mindlessly. You’d want the product to go inside the crack. Hence, you first need to seal the crack, so the product has nowhere to go but inside.
And yet, you can’t seal the crack completely because there’s no way for you to inject the product. That’s why you need to install surface ports.
The surface ports become an entry point for the product. Since you will be starting at the bottom port, the product will fill the crack while going up. Eventually, it will flow out from the next porthole above. That’s your signal to stop injecting on the current porthole, seal it and move to the next upper porthole.
By repeating this step, you’ll eventually fill up the crack with your chosen product. Now that you know the basic idea, you can move to the finer details in the step-by-step guide below.
- Step 1: Preparing the Crack
The first step is to clean the crack thoroughly. You’d want to clean about two inches of both sides of the crack. Also, you’d want the concrete wall to be exposed, and that means removing plaster, paint, or any coating.
Once you scrape and clean the areas around the crack, make sure to dust it off with a soft brush or a vacuum.
- Step 2: Marking Surface Ports
Repairing a crack requires the installation of surface ports. These ports are the entry points for your epoxy or urethane foam that will be injected later on in the process. This also means that you need to mark the spot where you want to place the surface ports.
As a rule of thumb, the distance between two ports should be the same as the wall’s thickness. This could be from 6 to 10 inches.
You’d want to start marking at the start of the crack that’s closest to the floor. Continue going up while marking the surface port locations.
Important: The area around the crack must be completely dry. If it is wet or damp, you must first dry it before moving to the next step. You can use a heat gun or compressed air to dry the wall thoroughly.
- Step 3: Injection Port Placement
The surface ports come with two parts – the surface port itself and the port cap. Remove the cap if it is attached to the surface port. Also, make sure you don’t lose the cap as it is essential for the upcoming steps.
The next step is to prepare your adhesive. After that, place the adhesive to the port. Bond the surface port to the previously marked locations.
Important: Do not allow the adhesive to block the surface port or the crack underneath it. Otherwise, the epoxy or urethane foam won’t reach the insides of the crack.
- Step 4: Sealing the Crack Surface
The next step is to place a surface seal over the crack and base of the surface port. You’d want the seal to be around one-eighth of an inch thick and spread about two inches from both sides of the crack.
However, place more adhesive around the surface port to ensure a good seal. If the crack goes through the opposite side of the wall, then you need to place the surface seal on that side. If you don’t do this, the epoxy or urethane foam will flow out on the other side instead of going up the crack.
Allow the surface seal to cure, about fingernail hard.
Here’s a tip that will make the task easier. Lightly stick the surface caps near the surface ports as the surface seal is drying. By doing so, you can simply pull out the surface caps when the time comes that you’ll need it. However, you want to place it lightly, or you will be having a hard time pulling it out.
Important: To ensure that there’s no leakage or blockage, squeeze a bottle of water into the top-most surface port. The water should trickle out from the surface ports below. Also, you don’t want the water to escape anywhere else aside from the surface port.
- Step 5: Injecting the Crack
The next step is filling up the crack with epoxy or urethane foam via the portholes. Hence, start loading the product into a dispensing gun with a static mixer attached. You’d also want to dispense a small amount if it’s a newly loaded product to purge out the air. Start from the bottom porthole and work your way up.
The key for best results in applying is slow, consistent, and low injection pressure. That’s why it is highly recommended that you use a spring-loaded dispensing gun. With a spring-loaded dispensing gun, a spring is compressed when you pull the trigger. As the spring decompresses, it injects the product into the porthole. Because it’s the spring that applies the pressure, a consistent product injection is achieved.
Continue injecting until you see the product coming out on the next porthole above. As you move to the next porthole, don’t forget to plug in the cap. Repeat this process until you are finished injecting the top-most porthole.
After that, let it cure. Drying times can widely vary. But generally, urethane foam will take two hours. For the epoxy, it’s typically 24 hours.
- Step 6: Remove the Surface Seal and Injection Ports
When the curing time has elapsed, the next step is taking off the surface seal and the portholes. You can use a putty knife to take out the surface seal. If the portholes are too stuck for a putty knife, you can knock it off using a hammer.
At this point, you’re mostly done with the crack repair. The next step is up to you. You can do a bit of sanding and dusting off. Or, you can do it thoroughly to prepare the wall for coatings like paint or plaster.
