It’s not good when a boat is sinking. When you have that foreboding or sinking feeling, something’s not good. It’s also not good when the foundation of your home is sinking!
A foundation, by definition, is the basis or groundwork of anything. Whether it’s a skyscraper or math skills, if you don’t have a solid foundation, the rest will eventually crumble. Nothing, including your home, will last for long with a shoddy or damaged foundation. Additionally, even well-designed foundations are at risk if not cared for. Your home is only as sound as your foundation, so house foundation protection is one of the best investments you can possibly make. Here are some tips on protecting your home’s foundation.
What Is a Cove Joint?
This joint, where your basement wall and floor meet, is known as a cove joint. It exists due to the way that a home’s foundation is poured. After your foundation footings are built, your basement walls are poured so that they slot into a keyway. This helps keep them properly aligned.
When your walls have cured, the basement floor itself is then poured. This leaves a small gap between the floor and the walls – known as the cove joint.
Why Does the Cove Joint Leak?
Following a heavy rain, ground water around your home will rise. It begins to push into any potential openings in your foundation. Because the cove joint is a necessary part of structuring your foundation, it’s a common entry point for water. As prolonged rains or heavy rains continue, they’ll begin to force their way in through these gaps. This is typically referred to as hydrostatic pressure.
Why You Can’t Just Seal the Gap Between Your Basement Floor and Wall
It may seem like an obvious solution to simply seal the cove joint to prevent water from breaching into your home. However, it’s not that simple. In the short term, a sealant applied along this gap between your basement floor and wall may prevent leakage. However, it will eventually fail in one of two ways:
#1. The water being blocked by the sealant will find another gap in your foundation to enter the home. Typically, this will be cracks in your foundation.
#2. The sealant you used will be forced off or penetrated by the water. Once this happens, all the water will leak through the opening in your sealant, rendering it useless.
Either of these events will happen due to the strength of the hydrostatic pressure. It’s not easy for water to push into your home. When it meets with resistance, such as a sealant, it will work its way through or around that resistance.
The Best Solutions to Protect Your Cove Joint
While sealing the gap isn’t recommended, you do have options to help protect your home from potential water damage. There are
multiple approaches to keep this water from leaking into your basement
Foundation wall failure typically happens slowly over time, and there are signs that you can see. But only if you know what to look for! Learn how to spot the signs and identify what’s going wrong with your wall before it fails completely.
How Do You Know If Your Foundation Wall is Leaning, Bowed or Bulging?
Fortunately, there are several indicators that can help you identify when your basement foundation wall is compromised. When looking for structural issues, they can present themselves differently depending on the type of inward movement your walls are experiencing.
Here are some of the most common signs of problems with your basement foundation wall:
- Cracks in your walls more than 1/8 inch wide
- Angled cracks from the corners of the wall or across the center
- Unleveled flooring
- Water seepage
- Walls sliding inward at the bottom or leaning in at the top
Distinguishing Between Types of Basement Foundation Inward Movement
Not all foundation damage is the same. If you think you’ve identified the early signs of failure, it can help to distinguish between leaning walls or bulging walls. The difference may not seem important, but it can help with locating the source of the problem and deciding on a solution.
Bulging walls often have horizontal cracks, as the pressure is closer to the center of the wall and will cause it to fold in from the center. You can measure for a bulged wall by using a plumb string attached to the ceiling and measuring the distance of the wall, bottom to top. If the wall measures longer than the plumb line, it indicates a failing wall that is likely to be bulging.
Leaning foundation walls will angle slightly. Most homeowners expect leaning walls to lean in from the top. In some cases, the inward movement comes from the bottom instead. Make sure to look for both.
What Can Cause a Foundation Wall to Fail?
Inadequate drainage is one of the most common ways that foundations suffer damage. As moisture drains into the foundation, it builds up against the side of your home and can cause soil heaving. Hydrostatic pressure is also a typical cause of water leaking into your basement.
You can prevent drainage problems from occurring. In addition to ensuring your home’s grading provides moisture with a path away from your foundation, gutters and spouts that direct water far away from your foundation is important.
If your gutters are damaged or clogged
Causes of Basement Concrete Cracks
The two primary parts of concrete are cement and water. After it’s poured, it cures to become solid. As the concrete dries, it will shrink. The degree of shrinkage is largely affected by temperature. If temperatures drop while your basement cures, that can cause cracks. Likewise, sweltering heat will rapidly dry your concrete – and curing too quickly also causes cracks. Even in perfect conditions, over time, your basement concrete will experience some degree of shrinkage.
While there are some ways to help mitigate shrinkage, such as controlled cracks in specific areas, it’s impossible to prevent them. There are certain areas that are more likely to develop these cracks than others, such as around doors or other sharp corners.
On the bright side, cracks in your basement floor due to shrinkage rarely result in any structural problems. However, they still open the doors for other problems like water or pests. That means they should be repaired and sealed whenever you identify them. While you should consider every crack a potential risk, most cracks under one-eighth of an inch wide aren’t a cause to be concerned.
Another common cause of cracks in basement floors is when the concrete slab begins to settle. Typically, settlement occurs when the
soil beneath your foundation is too unstable to support the weight of your home
That means you need to allergy proof your basement, and you’ll need to know where to start. EverDry Toledo can help! Read this list to learn the steps you can take to reduce your chances developing mold in the basement.
#1. Use a Dehumidifier
Excessive moisture creates the ideal environment for mold in the basement and dust mites. By reducing the moisture levels, you can make it difficult for them to thrive in your basement. When using your dehumidifier, you’ll want to aim for 35-45% relative humidity. Higher humidity is what promotes molds and dust mites, but if the humidity is too low it can promote viruses.
#2. Improve Ventiliation with the E-Z Breathe System
The E-Z- Breathe System can improve your air quality with no regular maintenance required. Once installed, this unit protects your home from poor air quality, as well as molds, toxins, and allergies. Learn more about improving your home’s atmosphere with the E-Z- Breathe System.
#3. Immediately Remove Mold in the Basement
This may seem obvious, but even the tiniest bit of mold needs to be removed as soon as possible. Never let the problem get out of hand and you can save yourself a lot of trouble down the road.
While some people believe musty smells are typical for basements, they’re not – they’re only a strong indicator of mold or mildew. Just because you can’t see it, doesn’t mean it’s not there! The moment you think you notice the smell of mildew or mold in the basement, identify the source and remove it.
#4. Replace Carpeting
Wall-to-wall carpeting may look nice in your basement, but it can absorb a lot of moisture over time. To prevent allergens, consider basement floor options like cement, slate, or linoleum. There are plenty of ways to keep your floor looking great without the need for carpet – and almost any other option reduces your risk of promoting mold in the basement.
#5. Fix Plumbing Leaks as Soon as Possible
Small leaks can be dealt with on your own with the right DIY knowledge, but sometimes the small problems are indicators of a bigger issue. It’s always best to call a professional to safely deal with any plumbing issues before they become disasters. Take every leak or break seriously, as water can quickly cause damage that requires costly repairs.
#6. Fix Cracks in the Foundation Immediately
It’s critical that you keep the foundation secure. A small crack inside of the foundation often means more cracks on the outside – and these all lead to water seepage that can not only foster basement allergens, but also cause severe damage to your home or property. If you notice cracks, contact us and we may be able to help prevent further leaks with

Types of Soil
Soil shifts and moves over time often as a result of how it handles moisture and the climate — including the freeze / thaw cycle. As soil shifts, it changes the support around your foundation, which can lead to cracks. And it’s those cracks that can allow in moisture and maybe even some pests.
Each type of soil is comprised of different properties that have various effects on the bedrock of a home. Soil with good structure is going to be more stable. The way in which soil handles wetting and drying cycles is also an important consideration, as expanding soil can put unwanted pressure on foundations and soil that retains too much moisture can cause the foundation to weaken.
Here are the most common types of soil and how they measure up:
Peat: Usually dark in color, peat is easily compactable because it holds a great deal of water, which makes it prone to shifting. This is not ideal soil for a foundation.
Clay: Because it’s made up of tiny particles, clay shrinks significantly when dry and expands when it’s moist. The extreme changes can put pressure on the foundation, which opens the door to potential cracks.
Silt: Usually smooth to the touch, this type of soil tends to retain water longer and drains poorly. This can push against and weaken foundations when wet.
Sand / Gravel: A better choice than peat, clay or silt, sand / gravel drains easily and does not retain moisture because it’s made up of larger particles. However, when wet, these particles can be washed away leaving gaps around the foundation.
Loam: Typically, a combination of sand, silt and clay, loam is an ideal soil type for supporting foundations, as it is able to maintain water at a balanced rate.
Rock: The strength and stability of rock makes it a great choice for foundations. However, it can be difficult to dig into, and homeowners should be sure the rock is level before constructing the foundation.
Improving Drainage Around Your House
Whether your home is resting on stable or not-so-stable soil, water drainage is an important part of maintaining the life of a foundation. Poor drainage can cause problems like water in the basement or structural damage, while proper surface drainage can lead moisture away from your home ultimately protecting the precious foundation. Here are some things you can do to ensure better drainage.
Roof gutters and downspouts: Gutters should be kept free of debris and direct water to downspouts that carry it away from the foundation. Be sure they’re draining at least six feet away from the home — downspout extensions can help!
Sufficient grading: Check to see if dirt is graded away from the home. Housing codes have various requirements, but it’s helpful if the ground slopes away from the foundation for a distance of eight feet or more.
Basement windows: Sometimes debris and water can collect near basement windows, so be sure to provide adequate drainage to the foundation drain.
Sump pumps remove excess water from around your basement and are best for minor amounts of groundwater. Ensure your sump pump is in good, working condition and consider a battery back-up.
Install foundation drains: This repair consists of removing portions of existing basement slab, installing new drains directing water to a sump pump and then installing new slab. Learn more about basement waterproofing options from EverDry Toledo.

Where is the Water Located?
Like any DIY renovation, proper planning before you start a can save a lot of headaches – and unexpected expenses – down the road. While it’s certainly more exciting to think about installing a big-screen TV or a stylish bar, keeping your basement warm and dry should be your first consideration. With that in mind, we’ve put together 10 basement remodeling tips to help keep your basement cozy, energy efficient, and waterproof, so you can enjoy your new space for years to come!
1. Don’t start until you’ve checked the building code and obtained all necessary permits.
Your project could face serious consequences if it’s not up to code, and you could be putting your home and your family in danger. This is particularly important if you’re planning plumbing and electrical work, which may have to be inspected. Know and follow the building codes. If you have questions, concerns, or you’re not sure your skills are up to the task, consult a licensed builder.
2. Check for moisture problems.
Moisture issues are a common basement concern, and if you don’t address them before starting your renovations, you could be setting yourself up for costly repairs down the road. Mold, insects, and high levels of humidity are all signs that you could have a serious basement moisture problem that’s beyond the fix-it skills of the typical DIYer. If you’re not sure what to look for, our experts can provide you with a free basement inspection and recommend the best waterproofing option for you.
Even if you don’t have a serious moisture problem, adding a vapor barrier to both the walls and floors prior to framing and finishing off these surfaces makes good sense. Lay down the moisture barrier, wait a day or two, then check underneath to see if and how much moisture may be coming through before continuing. If there’s still residual moisture after adding the vapor barrier, create a slight offset from the outside wall by adding thin slats of wood or metal called furring strips. These strips can also be used to help level out a wall that may be “wavy” to create a flat surface for adding framing. When it’s framed and insulated, face it with mold-resistant drywall.
3. Don’t skimp on the insulation.
Insulation will not only help control the temperature inside your basement, it will add another layer of moisture control. Plus, it will help dampen sounds coming in from the outside. Choose an insulation that includes a vapor barrier on both sides. Spray foam insulation can also be effective for basement walls, but check code requirements to ensure it allowed in your area.
4. Seal around rim joists.
Uninsulated rim joists (the joists on the outside edge of your basement walls) can create big energy losses. They can also be an easy entrance for mice or other pests. Insulate them with rigid insulation cut to fit. 2” extruded polystyrene is a good choice, but make sure it’s up to code. If you have a table saw, use it to cut strips equal to the depth of your joists. Then use a fine-tooth handsaw or utility knife to cut the strips to length. Fill small gaps with caulk, and the larger ones with expanding spray foam.
5. Seal around pipes and wires.
Seal small cracks around pipes and wires with high-temperature silicone caulk, and larger gaps with flame-resistant expanding foam. Close openings around chimney flues or other large openings by nailing sheet metal over them and sealing the edges with caulk. While they’re exposed, slip foam insulation sleeves over hot-water pipes to prevent heat loss and over cold-water ones to prevent condensation from dripping on the inside of the drywall or ceiling.
6. Add a drop ceiling.
A drop, or suspended, ceiling hides your plumbing and electrical lines, yet provides easy access to them if needed. Remember that drop ceilings will reduce the amount of overhead space available, so keep that in mind when planning your renovation.
To soundproof a drop ceiling, add fiberglass batts above the ceiling tiles, but make sure your tiles can bear the added weight. Although batt insulation is relatively lightweight, it can put enough stress on think drop ceiling tiles and break them. Don’t use fiberglass ceiling tiles – they can’t support the weight of insulation. If you’re thinking of using wood-and-gypsum ceiling tiles, they will need to be at least 5/8 inch (15 mm) thick to be used safely with batt insulation.
7. Make sure your flooring is waterproof.
You may be tempted to add carpeting or wood flooring to your new space, but that can be a bad idea. Even a waterproofed basement can fall victim to a malfunctioning sump pump, and one flood can ruin an expensive floor (see #10).
That doesn’t mean you have to be stuck with a drab floor of gray concrete. Here are a few great basement flooring options:
- Epoxy floor coatings are good if you can live with a hard surface flooring. Epoxy coating is inexpensive, comes in a lot of colors, is totally waterproof, and easy to apply.
- Ceramic tile comes in an almost endless variety of colors and styles. In fact, you can even buy tile that looks amazingly like a wood floor! It’s unaffected by moisture and goes directly onto concrete that’s smooth and free of cracks.
- Vinyl tile and sheet flooring also goes directly over prepared concrete and will withstand even minor flooding. A vinyl floor can provide some cushioning underfoot, and it’s fairly inexpensive.
- Engineered wood flooring gives you the warmth and beauty of real wood with the stability and moisture resistance of laminate construction. Click-together tiles and planks are DIY-friendly and easy to install as a floating floor system. Check to make sure the type you choose is rated for below-grade basements.
- Rubber flooring comes in sheets and DIY-friendly tiles with interlocking edges. Rubber floors are nicely cushioned and come in a wide variety of colors, making them a good choice for basement playrooms.
Remember, no matter what flooring you choose, it’s important that you take steps to keep your basement as dry as possible. That means grading out foundation soil so it slopes away from foundation walls at least four inches over 10 feet, adding extensions to your downspouts so water exits at least five feet away from your house, and keeping gutters in good repair.
8. Consider your heating options.
Tying into an existing HVAC system will usually makes the most sense (and save the most dollars on remodeling costs). Remember, warm air rises, so it makes sense to install heating vents at floor level. For this reason, baseboard heating is also good option.
If cold basement floors are a problem, you can warm them up with electric heating cables or mats. This type of heat doesn’t warm the room much, but it makes floors much more comfortable.
9. Don’t remodel the utility room.
Keep the area around HVAC units and water heaters clear, open, and unfinished. These spaces have specific code requirements for spacing and framing. Plus, you’ll need access for inspection and/or repairs.
10. Have a backup plan for your sump pump.
It’s best to have both a battery backup for your main pump, in case of a power outage, and a second pump, in case the first one gives out. You can also install an inexpensive, battery-operated alarms that detect water to notify you if there’s water on your basement floor.

What is Frost Heaving?
Frost heaving occurs when the soil freezes and thaws. When it freezes, the water contained in the soil expands, causing the soil to expand with it. The expanding soil tends to soak up even more water, and when thaw occurs, the soil shifts and moves, creating uneven pressure on your foundation. The result? An unstable foundation, cracks, and possibly a wet basement.
Most frost heaving occurs in areas with silty soil or soil with a high water capacity. Builders can compensate for these conditions by ensuring the base of a home’s foundation is well below the frost line (in houses with basements), adding drainage tile around the foundation, backfilling the area with porous materials such as gravel for optimum drainage, and properly grading the topsoil to direct water away from the house.
Telltale Signs of Frost-Heave Damage
The biggest clue of damage left by frost heaving is cracks. Often seen in older homes, frost heaving leaves a pattern of cracks around the support columns in a basement floor. You can see a good example of this here.
Another characteristic of frost-heave damage is horizontal cracks along the upper part of a basement wall where it meets the surrounding topsoil – the soil most affected by the freeze-thaw cycle.
Tips for Preventing Frost Heave
- Replace the soil surrounding your foundation with more porous alternatives such as gravel and/or fill sand, which is a blend of sand, soil, and clay.
- Add a drainage system at the base of a foundation, like a French drain, to drain the water away.
- Dig top-level and subterranean reservoirs to redirect water away from your home’s foundation.
- Insulate your home’s foundation to minimize heat loss between the foundation and the surrounding soil. When heat transfers to the surrounding soil through foundation walls, it enhances the freeze-thaw cycle.
- Make sure your gutters are in good working order and drain rainwater at a sufficient distance (at least six to eight feet) away from your house.
Foundation Repairs May Still Be Necessary
Following the above steps are preventative measures that can dramatically reduce the risk of foundation failure due to frost heaving. But even with these precautions, it’s not always possible to reduce the risk 100%.
