Basement Waterproofing in Columbus

Water leaking inside your basement, especially during or following heavy rain, is common, but it is not safe or healthy for your home or family. Columbus’ silty and clay soils may not always be able to handle the 40 inches of rain and 22 inches of snow the area typically receives. Not only can these soils flood, but they can contribute to hydrostatic pressure that, in turn, leads to basement cracks and leaks. Improper foundation drainage and faulty sump pumps may not be able to keep up with all the water, either. Ohio Basement Authority will permanently safeguard your home with our trusted, customizable interior drainage, sump pumps, dehumidifiers, wall vapor barriers, and other basement waterproofing solutions. 

Foundation Repair in Columbus

Your house relies on its foundation to stay standing for years to come, and the foundation depends on the underlying soil for stability. The varied silty and clay soils throughout Columbus can easily become unstable due to a lack of moisture or too much moisture from 40 inches of annual rainfall and 22 inches of annual snowfall. Without proper support, the foundation will start cracking, sinking, settling, heaving, or suffer other damage. You’ll notice telltale signs of trouble throughout your house including cracking walls, uneven floors, drywall nail pops, bowing walls, sticking windows and doors, and cracking and leaning chimneys. Ohio Basement Authority’s foundation repair solutions including wall anchors, wall braces, carbon fiber wall straps, crawl space supports, helical piers, and push piers will bolster your foundation for permanent protection. 

Crawl Space Encapsulation & Repair in Columbus

Instead of a full basement, some Columbus homes have a crawl space underneath them to lift them off the ground, or a partial crawl space might be adjacent to a basement area. If your home has a crawl space, it could be in danger of damage from water and humidity. Columbus has a humid continental climate with hot and humid summers, cold winters, and year-round precipitation (40 inches of rain and 22 inches of snow). Open vents let in water, pests, and unconditioned, humid air. This creates a perfect storm for hazards including mold growth, infestations, wood rot, and unpleasant odors, all of which will affect the rest of your home because of the stack effect. Ohio Basement Authority can stop these issues in their tracks with trusted crawl space repair and encapsulation solutions including drainage, sump pumps, dehumidifiers, vapor barriers, vent covers, and support posts

Concrete Lifting & Leveling in Columbus

Your property’s concrete like your driveway, sidewalk, and exterior steps can succumb to damage over time, even though concrete is a tough material. When Columbus’ year-round precipitation (40 inches of rain and 22 inches of snow) interacts with the area’s silty and clay soils, these soils can quickly become unstable. They will expand, shrink, heave, sink, and settle, and cannot support the concrete slabs above. The concrete will then crack, sink, become uneven, and result in tripping hazards and other problems. Concrete lifting and leveling methods have come a long way, and Ohio Basement Authority offers a unique solution that will effectively restore your concrete’s safety and appearance. Our polyurethane foam injections are lightweight, yet durable and can be used on many areas including your sidewalk, driveway, pool deck, and interior slab floors

About Waterproofing, Crawl Spaces & Foundation Repair in Columbus, OH

Your foundation will endure a lot of moisture issues over the years. Floods, melted snow, and even humidity can all negatively affect your home in a variety of ways. Of course, the soil surrounding your foundation will also take on far too much water than it can realistically hold because of this. Over time, all that added water weight can start to push up against your foundation and cause it to shift out of its original placement or crack altogether. 

This phenomenon is called hydrostatic pressure, and it is unfortunately quite a common cause of foundation damage. Hydrostatic pressure can also take another form as well. Water can also become trapped within your concrete foundation’s pores. This itself is not much of a problem. When winter comes and that water freezes over, however, the expanding ice can then crack the foundation from within. 

A common construction phenomenon known as the clay bowl effect can also negatively impact your foundation. When contractors first go about building a new home, they will dig a large hole where they plan to lay down the foundation and either a basement or crawl space. After these components are installed, there will be some space left around it that the contractors will backfill with the soil they dug up. This creates a much looser bowl of sorts surrounding the foundation. Of course, Cincinnati’s silt soil is already quite loose, which only makes this soil all the more prone to washing out during a storm. As a result, your foundation might settle into the remaining soil and even crack into pieces. A shifted or settled foundation can start to impact other structures in your home, so you must call an expert to repair it as soon as you can.

When you invest in regular crawl space inspections, you can get ahead of the worst of the damage that wood rot can do to your home. These inspections are typically quick and non-invasive. By the time area professionals finish looking over your space every year, you’ll have a better idea of what kind of condition your home is in and what means you need to invest in to protect it.   

The Cursory Inspection   

To kick a crawl space inspection off, the professionals serving Cincinnati and Columbus, OH, need to look over the entrance to your space. To be up to code, your entry point needs to be two feet wide and 18 inches tall. If an inspector cannot safely enter your crawl space, you will fail your inspection and need to have your entrance expanded or otherwise remodeled with modern safety requirements in mind.   

As long as a professional can get into your crawl space without putting themselves in danger, they’ll move on to the superficial inspection. A superficial inspection lets professionals identify anything obviously wrong with your space, including wood rot, mold clusters, vapor barrier damage, standing water, and so on. If an inspector is able to identify any of these things in your crawl space, professionals will call off the rest of your inspection to start discussing your potential repairs.   

In-Depth Crawl Space Assessments   

You’re not out of the woods if you pass your initial and superficial inspections. Professional contractors serving Cincinnati and Columbus, OH, will also conduct full assessments of your crawl space if they believe your space may benefit from additional protections.   

Crawl space inspectors, at this point, will take a closer look at the nooks and crannies of your crawl space. They’ll want to identify any early signs of rot or damage before those symptoms start to spread. Alternatively, if it doesn’t appear that your crawl space is suffering from even mild damage, they’ll want to identify any weak points that may need protection from external forces. This stage of your crawl space inspection is effectively preventive and designed to ensure your space remains secure in the months and years to come.   

Efflorescence can be tricky to spot at first glance. However, there are a few ways you can identify if your basement is dealing with efflorescence or something else entirely.  

  • What Materials Make Up the Interior of Your Basement?  

Because efflorescence is made up of water and water-soluble salts, it might help to know what kinds of salts in building materials can be affected. Calcium sulfate (found in bricks), sodium sulfate (found in cement-brick mixtures), sodium carbonate (found in mortar), and potassium carbonate (also found in mortar) are all salts found in building materials commonly used in basement construction.  

Keep in mind that different materials in combination with these water-soluble salts may display different discolorations and effects, so you should be able to identify signs of efflorescence along different surfaces.  

  • How Fast Can Efflorescence Spread?  

Efflorescence can spread fairly fast down your basement walls and along your floor. The name “efflorescence” does mean “to flower out” in French, so you can imagine how quickly this substance can spread around your basement once it settles inside.  

According to the Masonry Institute of America, efflorescence can develop as quickly as one month after the initial construction of the building to up to one year after completion. It is a truly frustrating substance that builders have tried their best to prevent and avoid at all costs. If your efflorescence problem has cropped up long after your home has been constructed, however, then this is likely due to a hidden leak or flood dredging up the salts embedded within the very walls and floor of your basement.

All cracks, no matter how small, can present a threat to the surrounding concrete and your Dayton or Springfield home as a whole. Of course, you might be too busy to deal with every single threat of damage your home already faces, so it is important for you to know which cracks can be left alone for a short period of time and which must be repaired as soon as possible.

Hairline cracks are any cracks that measure less than 1/8 inch wide and will not pose much of a threat to your foundation nor the surrounding concrete. The same can be said for cracks that measure anywhere between 1/8 to 1/4 inches wide, though you should still keep a close eye on these in case they expand outward even further. Of course, even if you can leave these cracks alone for a short period of time, it is important that you set up an appointment with a concrete expert as soon as you can to repair these cracks. Expanding cracks are often ignored, which can result in easily preventable foundation damage.

Any cracks that measure wider than 1/4 inch wide must be repaired as soon as possible. Not only can the damage spread out to the surrounding concrete, but also it can extend down to the foundation as well. Moisture, washed-out soil, and plenty of other issues can easily cause these cracks to expand or spread out further, so it is important for you to not just maintain the concrete, but the supporting soil, too. Ohio Basement Authority’s SettleStop PolyRenewal™ solution can repair both, all while closing any cracks or holes in just 15 minutes! You will be able to walk along your concrete slabs the same day we implement repairs!
