Basement Waterproofing and Crawl Space Encapsulation Repair in Duluth-Superior, MN Metro Area

Summer is the muggiest time of year in the Duluth-Superior metro area , but did you know that you can eliminate some of that suffocating humidity by waterproofing your basement or crawl space? Due to the stack effect, 50% of the air that you breathe in your home comes from your home’s sub-level. A humid basement or crawl space can cause problems with your indoor temperature and humidity levels, so the only way to combat this is by investing in waterproofing solutions.

A Duluth-Superior basement or crawl space isn’t fully waterproof until there’s a system in place to combat flooding, groundwater, seepage, and humidity. If any sort of flooding occurs, then interior drains and sump pumps can collect the water and pump it out. The same system can be put in place to prevent the foundation from being exposed to excessive amounts of groundwater.

To stop leaks and seepage from either windows or broken pipes, a perimeter interior drain can collect the water before it even has a chance to hit the ground. And for humidity, there’s no better material to deter water vapor from entering your Duluth-Superior basement or crawl space than a vapor barrier. If you want a device that allows you full control over the humidity levels in your foundation, then we can install a dehumidifier that does just that.

Foundation Repair in Duluth-Superior, MN Metro Area

Helical Pier on Concrete foundation in Duluth, Minnesota

Because it’s the base that holds everything together, your foundation should be the most structurally sound portion of your Duluth-Superior home. Unfortunately, this isn’t always the case since most homeowners experience some form of foundation problem in one way or another. Once it’s there, you may not be able to reverse the problem, but you can stop it from progressing with the right repair solutions.

Ignoring foundation problems in and around your Duluth-Superior home can lead to a disruption of your current home life. Excessive basement and crawl space flooding, cracked walls, and jammed doors are all problem signs that get progressively worse unless the foundation is repaired. As the foundation itself crumbles, so does the rest of the home. If the problem goes on for too long, then the house may even become too unsafe to live in.

To ensure its functionality, a foundation should only have to be repaired once. Having high-quality, well-designed foundation repair solutions will put a stop to your Duluth-Superior home’s foundation problems once and for all. This is why, at Innovative Basement Authority, we recommend the best of the best for foundation repairs. From galvanized steel helical piers for foundation settling to sturdy, top-of-the-line wall anchor supports for bowing basement walls.

Concrete Lifting Repair in Duluth-Superior, MN Metro Area

Making sure that the concrete on your Duluth, MN or Superior, WI property is even is a matter of safety. An uneven concrete path is a sign of slab settling, which happens when concrete slabs no longer have a solid layer of soil to rest on. Uneven driveways, steps, and patios aren’t just cosmetic nuisances; they also can cause serious injuries.

There are many concrete lifting methods available on the market, but for the homeowners of Duluth-Superior, Innovative Basement Authority has a solution that not only repairs the concrete, but also future-proofs it as well. With SettleStop PolyRenewal™, experts can inject polyurethane foam under the concrete and lift the slab. The characteristics of polyurethane provide the concrete with a layer of support that does not erode or disintegrate with time. When an expert recommends SettleStop PolyRenewal™, it’s more than just repairing your slab; it’s also easing your mind about concrete settling for years to come.

SettleStop PolyRenewal™ can be used on any kind of settling concrete around your Duluth or Superior home, be it your driveway, garage floor, sidewalk, or concrete steps. Unlike traditional mudjacking, the tools needed to inject polyurethane foam are small, allowing experts to work on areas that could otherwise not be lifted. Most lifting jobs can be done in a single day and the curing time for polyurethane foam is 15-30 minutes, making SettleStop PolyRenewal™ the most convenient concrete lifting method to date.

About Waterproofing, Crawl Spaces & Foundation Repair in the Duluth-Superior Metro Area

A sagging floor is almost never a problem with the actual floor itself but rather a problem with the floor joist that’s meant to support it. When a floor joist in a ventilated crawl space is damaged, it’s usually because of wood rot or water damage, which are both caused by poor waterproofing solutions. Luckily, not all is lost when you have damaged floor joists. Replacements can be costly, but with a support system like SettleStop IntelliJack™, you can repair your floors in no time at all.

SettleStop IntelliJack™ is a crawl space stabilizer that helps failing joists support your floor. SettleStop IntelliJack™ is more than a simple support jack: It makes sure that the floor stays even perpetually because it does not rely on unstable soil. This means that, regardless of the soil conditions in your crawl space, the support jacks will not budge. SettleStop IntelliJack™ is made of non-corrosive galvanized steel, can be installed in a single day. Each support jack has an allowable load capacity of more than 24,000 pounds.

SettleStop IntelliJack™ can only be installed by Innovative Basement Authority experts. It’s not advised that you attempt to repair your sagging floor yourself and going into a structurally unsound crawl space can be dangerous. It is also not advised that you attempt to mimic the results of SettleStop IntelliJack™ using other methods, since the outcome will not be the same without the knowledge, tools, and material used by professionals. If you are interested in SettleStop IntelliJack™ for floor joist repairs in your Duluth-Superior home, then contact your local experts.

Crawl space humidity should be given more thought because of how it impacts a home’s energy consumption. Due to the stack effect, most of the air circulating in your Duluth-Superior home comes from your crawl space. The stack effect is a term used to describe how air travels throughout your home. Hot air is always trying to travel towards colder temperature, so the warm air from the outside flows into your crawl space and then rises into your home. This affects how well your AC can cool your home, causing your energy bill to rise.

During the winter, the cool air that enters through your crawl space is much denser than hot air, so it pushes the warm air in your home to the upper portions of your house. Again, this affects how well the way your HVAC system can keep the temperature in your home comfortable. Because of the invading air from outside, your HVAC systems overwork themselves and consume more energy than they should.

The only way to stop this is to properly insulate your crawl space, and make sure that it’s fully waterproof. Waterproofing solutions like encapsulation will seal your crawl space and prevent water seepage, while insulation materials will prevent air from flowing in and out of the space. The kind of insulation you need for your crawl space should be reflective. Absorbent material will only deteriorate as it takes in all the moisture in the crawl space, so to improve the energy efficiency in your home, a crawl space repair expert will recommend AquaStop ExTremeBloc™ insulation.

Basement humidity is to be expected given the fact that most of them are built with little to no waterproofing solutions. There are many ways in which groundwater and surface water can seep through to your basement, so unless you have everything covered, you can expect high levels of humidity. The most common ways basements become humid is due to windows, broken machinery, and leaking pipes. If your basement’s window frame is warped, then it’s very easy for rainwater to leak through and raise the overall moisture level in the basement. Regularly checking the pipes, washing machine, HVAC systems, and any other water-based machine can help prevent the worst of it.

From afar, concrete seems like a solid, dense material, but if you look closely, you’ll notice that its surface is rough and might even have some holes in it. Concrete is porous, which means that moisture from the surrounding soil can easily permeate through the concrete and reach the inside of the basement. Unless you have a vapor barrier, water vapor will continue to infiltrate your basement and increase the humidity levels significantly. Even if your basement is finished and your walls are lined up with wood or drywall, these materials are just as porous as concrete is, so water vapor will still find a way through. Waterproof paints are not good enough to stop vapor seepage, and they only last about two years anyway.

Invisible forces like water vapor make it difficult for Duluth-Superior homeowners to combat basement humidity, but the right solutions can solve the problem for you. If you truly want to make sure that your basement stays as dry as possible, then investing in waterproofing methods is the way to go. Tools like dehumidifiers, vapor barriers, and interior drains work in tandem to prevent water seepage and keep the moisture away from your foundation.

Foundation settling is like a silent storm that sneaks up on Duluth-Superior homeowners when they least expect it and gives them little time to prepare for the damage. To avoid costly repairs and extensive damage to your property, you need to know what signs to look out for as early as you can. To understand why settling damage appears the way it does, the first thing you should know is how settling affects homes. All homes sit on top of an even layer of dense soil. When that layer erodes and becomes uneven, the home begins to sink (either sideways or straight down), and a part of the foundation can break off as the house’s center of gravity shifts.

Inside the home, you’ll begin to see cracks along the walls and ceilings since one side of the house now has to support the weight of the side that’s sinking. This can often be too much pressure for the home to bear, so the structure falls apart with time. Cracks can be spotted both in the upstairs living area and in the basement. Because the house is tilting sideways, frames become warped, causing doors and windows to jam upon usage. The floor becomes uneven as the house shifts to one side, and basement or crawl space flooding becomes more frequent as the broken foundation allows groundwater in.

Outside, you can spot the signs along the mortar. If the mortar has stair-step cracks along the joists, then the house is settling. If the crack is wider at the top than at the bottom, then the settling is significant and has been going on for a long time. A tilting and cracked chimney is another clear sign, as well as porch and patio handrails. If you aren’t fully sure of the signs you’re seeing and you still can’t determine whether or not your home is settling, then you can always contact Innovative Basement Authority for a free inspection.

You have to be incredibly well-versed in the problem signs of concrete settling to be able to detect it early. This is because the soil erosion that causes settling in the first place happens underground where the homeowner cannot see it happening. But, in a place like Duluth-Superior, besides detecting slab settling early, it can also be difficult to detect the reason why your slab is settling in the first place. Depending on the soil characteristics of your property, your slab may be settling for a number of different reasons. The problem is, Duluth-Superior has some of the most diverse soil content in the Midwest.

The soil of the region can be abundant in clay and poorly-drained as well as sandy and loose. One of the many soil types found are Histosols, which are full of organic material, retain water incredibly well, and swell when exposed to moisture. Once dry, they shrink and lose volume. This volume reduction causes gaps to appear under the slab, which is why one side of the slab sinks low to the ground when settling. Clay soils like Histosols erode regardless of whether or not the terrain is at an incline.

Other soil types found in northern Minnesota, like Entisols, are sandy, coarse, friable, and loose. They do not swell when exposed to water because they don’t have enough clay and organic materials to absorb moisture. However, because the particles are loose and shifty, they wash away easily when met with a stream of running water. It’s difficult to know what exactly is going on with the soil on your property until you get it tested to see what kind of soil it is. Once you have a better understanding of your property’s soil, you can begin making the necessary changes to prevent as much slab settling as possible.

Mudjacking is one of the oldest concrete lifting methods in the industry, but just because it’s a classic method doesn’t mean it’s the best. There are many problems that can arise from lifting a slab with the cement slurry used in mudjacking, but luckily, SettleStop PolyRenewal™ eliminates all those issues. To start, SettleStop PolyRenewal™ is simply a much faster and convenient procedure. The curing time is shorter (15-30 minutes as opposed to the 24-48 hours in mudjacking), and the equipment used is smaller, allowing contractors to work in smaller spaces. The holes that need to be drilled into the slab are smaller, meaning that there’s minimal disturbance to the weakened concrete slab.

Another difference between mudjacking and SettleStop PolyRenewal™ is the way the materials interact with the soil. The material used for SettleStop PolyRenewal™ is a closed-cell polyurethane that is incredibly firm and capable of supporting a lot of weight. Despite its density, it’s lightweight enough that it won’t further displace the soil underneath the slab, unlike the rough, heavy cement used for mudjacking. Because it’s a waterproof material, it will not washout or erode and it will not become vulnerable when subjected to the freeze-thaw cycle. Its impermeable characteristics will also prevent water from reaching the soil and washing it away or triggering a shrink-swell cycle.

Concrete slabs sink because they can no longer rely on a stable layer of soil to hold them up. If you eliminate all the factors that cause soil erosion in the first place (washout, shrink-swell, freeze-thaw), then you can ensure that the slabs will have a secure foundation. While mudjacking can be used to lift concrete, it cannot future proof a slab to make sure it doesn’t settle again. This isn’t the case with SettleStop PolyRenewal™. If you want more than just a quick fix and you want to guarantee the settling problem is solved once and for all, then you’ll want to invest in SettleStop PolyRenewal™ instead of mudjacking.
