  • Love these guys. They are professional, punctual, and saved me $1,000's explaining exactly what my foundation problem was and what I needed. Other companies were trying to sell me on the bells and whistles pushing services I didn't really need. These guys were transparent and the pricing for the job came out about $500 less then the other quotes.

  • Does Foundation Movement Affect Chicago, Illinois?

    Ground movement and the foundation damage that commonly occurs as a result are both widespread problems throughout much of Illinois.

    Property owners in Chicago, Addison, Arlington Heights, Naperville, and many other nearby cities experience foundation issues at an alarming rate.

  • What Causes Foundation Problems In Chicago, Illinois?

    Multiple factors contribute to the dangers of structural problems in Chicago. We’ll discuss the most significant issues below and provide an explanation of the impact they have on your home’s foundation.

    Expansive Soil

    The soil in Chicago belongs to the Alfic Udarents subgroup of soil classification. This effectively means that the dirt in the area has an abnormally high ratio of clay to other particles and drains very slowly.

    Expansive clay soil puts concrete foundations at risk for three primary reasons.

    The first problem is that the ground readily absorbs water, which soaks into the gaps between the tiny clay particles. The more runoff that comes in contact with the soil, the heavier and more voluminous it becomes.

    The ground swells and puts added stress on your concrete block walls and slab. The hydrostatic pressure is often intense enough to crack the concrete, creating weaknesses that require structural repair.

    The second issue is the opposite of the first: the soil becomes less voluminous when it dries. Following rainfall and ground swelling, the runoff gradually drains into the earth, decreasing the soil’s moisture content.

    The dirt will shrink away from your concrete, relieving the hydrostatic pressure on the walls and causing the slab to settle deeper into the ground.

    This downward movement of the slab is hazardous because it doesn’t always occur uniformly. The soil around your home often dries unevenly, leading to differential settling that can cause significant structural damage.

    The last major problem with Chicago’s expansive soil is that it retains water more successfully than typical dirt. As such, runoff and floodwater are held against the concrete for extended periods, giving it ample opportunity to soak through cracks or pores in the foundation.

    It’s not uncommon for Chicago homeowners to experience a moist or wet basement or crawlspace.

    Above-Average, Concentrated Rainfall

    Chicago gets hit with just under 43 inches of rain annually, almost one and a half times the national average. Above-average rainfall leaves the clay soil saturated for much of the year, so hydrostatic pressure is continuously a problem for the concrete under your home.

    Lake Michigan Chicago

    The rain is somewhat steady from month to month year-round, but most of the precipitation in the summer and fall occurs in large storms that bring most of the month’s rainfall.

    The concentrated rain not only contributes to the issues with expansive soil but also means there is plenty of time for the soil to dry between incidences. The frequent wet-dry cycle in Chicago lends itself to differential settling and undue stress on your foundation.

    Flash Floods & Deep Frost Line

    Flash flooding is a significant problem for homeowners in Chicago for two main reasons. First, the clay soil drains very slowly, so the concentrated and heavy rainfall quickly accumulates on the surface and slowly dissipates.

    To make matters worse, Chicago has a combined storm drain and sanitary sewer system, meaning there is a constant and heavy load on the drains throughout the city. They are often unable to keep up with the demand during heavy rain.

    Most Chicago homes have a basement because the frost line is very deep, around four to five feet below the surface, on average. Plumbing lines need to be run below this depth anyway, so most builders continue to dig out for a full basement for the added convenience and living space.

    The resulting problem is that basements need to be set deep in the ground, but the frequency of flooding puts all underground rooms at severe risk of water intrusion and moisture accumulation.

    Limestone Bedrock

    Finally, many areas throughout Illinois are underlain by limestone bedrock. Limestone is supportive, but it dissolves in the presence of water.

    When groundwater or draining runoff interacts with the bedrock in Chicago, it gradually wears it away, creating underground voids.

    The result is referred to as a karst landscape, which eventually causes sinkholes to form on the earth’s surface when the caverns and channels eventually collapse.

    Sinkholes are more common in other parts of Illinois, but they still occur in Chicago and other urban areas throughout the state.

    The karst landscape creates ground instability and contributes to differential settling under your house, often resulting in costly structural damage.

  • What Are The Signs of Basement Foundation Damage In Chicago, Illinois?

    The various underlying causes of foundation damage in Chicago can elicit differing responses under and inside your home. We’ll discuss the most common signs of an under-home problem below and which of the issues discussed above is the likely culprit.

    Foundation Cracks

    Foundation cracks are generally unavoidable, but not all fissures represent structural damage. The location and width of the gap will often be the biggest clues as to the severity of the problem.

    Hairline Floor Cracks

    Most homeowners notice thin, meandering cracks in their crawlspace or basement floor. As long as they are level from side to side, these generally just indicate normal concrete settling and don’t suggest structural damage.

    It’s best to have a foundation repair contractor seal them to help maintain a dry basement.

    Wide or Uneven Floor Cracks

    If the cracks in your basement floor widen to ⅛” or more or have one side rising above the other, the problem is likely differential settling.

    They suggest that a section of your slab has lost support from the soil underneath and is sinking deeper into the earth than the rest of your home. These gaps need immediate stabilization.

    Vertical Wall Cracks

    Cracks that travel vertically up and down your concrete block wall are most often a result of normal settling as well, and they rarely indicate a larger problem.

    Some minor stabilizing may be necessary for gaps that are broader than ⅛”, but most simply require a polyurethane or epoxy sealant.

    Horizontal Wall Cracks

    Horizontally-oriented wall cracks signify that the hydrostatic pressure from the clay-rich soil outside has forced your wall to bow inward to the point of cracking.

    These fissures indicate that your foundation’s structural integrity has been compromised, so extensive foundation crack repair and stabilization are needed.

    Step-Shaped Wall Cracks

    The last type of basement wall crack you may see appears in a step pattern along the contours of the concrete blocks.

    These gaps indicate differential settlement, either from shrinking clay soil or from the area’s karst topography. These cracks typically require the most costly wall repairs.

    Moist or Wet Basement or Crawlspace

    The abundance of basement foundations, expansive clay soil, above-average rainfall, and risk of flooding all contribute to under-home water and moisture problems.

    There are varying related symptoms you may notice, depending on whether liquid water or water vapor is entering the area.

    Liquid water usually leaks through cracks in the concrete, so you may see water, water stains, or wet spots on or around fissures in the wall or floor during rainfall. Water damage, standing water, and puddles on the floor are also reasonable indications that foundation cracks are leaking.

    Water vapor isn’t visible, so you’ll have to rely on some other signs if moisture is entering through pores in the concrete. Mold growth and musty odors under your home are good signs of moisture problems.

    Efflorescence is a white, powdery staining left on the walls after incoming water evaporates. Moist air can also suggest a water vapor issue, as can the insects and rodents it attracts to the space.

    Efflorescence on the wall

    Finally, the air inside your living area can suggest a problem with water or moisture underneath. Humidity seeping upstairs can lead to uncomfortable temperatures or unusually high utility bills.

    Additionally, airborne mold spores entering your living space from your crawlspace or basement can elicit allergy symptoms in you or your family.

  • How to Find Signs of Foundation Damage In Chicago, Illinois?

    Severe foundation problems seldom appear in response to a single event. Instead, they start small and slowly develop over time. As such, identifying and addressing the signs of damage to the concrete under your house quickly can keep your repair costs low and the damage to your property to a minimum.

    The best way to monitor your home for gradual changes is to inspect it regularly. We’ll detail a full home inspection below that you can complete every three months to keep tabs on your foundation’s health.

    Inspect the Concrete Under Your House

    Begin your inspection outside and look for cracks and visible sinking of the concrete under your house. Pay special attention to the corners, which is where most problems with differential settling will be evident.

    Next, move into your basement and continue looking for foundation cracks. Report any horizontal or stair-step wall cracks and wide or uneven floor cracks to a foundation repair specialist immediately.

    If you have problems with moisture or water in the space, consider having a foundation contractor seal hairline floor cracks or vertical wall cracks as well.

    You should also look for the symptoms of water intrusion, including standing or pooling water, wet concrete, musty or dank smells, visible mold growth, water damage, and efflorescence or water stains on the walls.

    Continue Inside Your Home

    Once you’ve checked your foundation thoroughly, move to the interior of your house, where symptoms of foundation movement regularly appear. The floor joists and framing in your home rely directly on your foundation for a stable and level base, so abnormalities in your flooring and walls can suggest that basement or crawlspace repair is required.

    Look for leaning or bowing walls, nail heads bulging through the sheetrock, drywall cracks around door and window frames, doors and windows that are difficult to open or close, and buckling or sloping floors.

    This is an excellent time to compare your recent utility bills to those from previous years to check for changes and assess any allergy symptoms indoors that may have gone unreported.

    Finish Your Inspection Outside

    Finally, check your home’s exterior and your yard for symptoms of poor drainage and expansive soil that could be detrimental to your foundation if left untreated.

    Leaning retaining walls, an uneven yard, puddles developing on your lawn during rainstorms, a leaning or cracked chimney, irregular roofing, and cracks in your siding can all suggest that you have a problem with your foundation.

  • Cost of Basement Foundation Repair In Chicago, Illinois?

    On average, foundation solutions cost Chicago homeowners approximately $5,500 to repair. Your total might be as low as $300 or above $20,000, so it can be challenging to estimate what your home improvement will cost. We’ll include some more specific prices below to give you a better idea of where your price will fall.

    Cost to Seal Foundation Cracks

    Hairline cracks in the basement floor and vertical gaps in the foundation walls are usually the most straightforward repair. Most foundation repair contractors in Chicago charge between $300 and $800 for this wall repair.

    Cost to Fix Horizontal Cracks

    Horizontal cracks generally require stabilization, and hydrostatic pressure in Chicago is best treated with an added exterior drainage system.

    Earth anchors are the best solution for wall stabilization, as they use tensioning rods to help your foundation resist added pressure from the soil. These usually cost between $3,000 and $5,000, depending on how long the crack and your wall are.

    Most foundation repair companies can add a drainage system to this setup for an additional $2,500 or so.

    Cost to Fix Sinking Foundation or Stair-Step Cracks

    Most foundation repair specialists will use underpinning to correct differential settling. This repair involves installing additional foundation piers under your concrete to support it from underneath and take the burden off of the expansive clay soil.

    Steel piers and helical piers cost around $1,000 and $3,000, respectively, so the type of piling used can have a significant impact on your total price. Most homeowners pay between $5,000 and $20,000 for underpinning.

    Cost to Fix Ongoing Water or Moisture Problems

    Basement waterproofing systems are the best remedy for frequent or recurring water and water vapor issues beneath your house.

    Your basement system can include various pieces of equipment and strategies, including French drains, sump pumps, dehumidifiers, vapor barriers, crawlspace encapsulation, drain tile systems, and more.

    The average cost for a waterproofing setup is $5,500, depending on how comprehensive your system needs to be and warranty included with the equipment and workmanship.
