Types of foundation problems we fix

Signs of Foundation Problems Worth a Closer Look

After being in this industry since 1985, we’ve gained proven expertise in residential foundation repair in Kansas City across MO and KS. Due to our vast experience in solving countless and complex foundation challenges, we can address and fix a spectrum of foundation problems, such as:

A symptom is a clue. An inspection establishes what is causing it.

A laser level checking a floor and wall
A floor that slopes, dips or feels uneven

Sloping and Uneven Floors

Movement of soil beneath the foundation, substandard construction practices, or water damage cause floors to be uneven and slope. If this issue is not fixed, it can easily compromise the foundation’s structural stability and cause an uneven distribution of weight across floors. Sloping or uneven floors are a reason to arrange a foundation inspection.

Stair-step cracks following brick mortar joints
Cracks in drywall, brick or foundation walls

Wall Cracks

One of the early indicators of underlying foundation problems is wall cracks. Here are different types of wall cracks that you can notice in your home:

Basically, if you see any of these cracks progressively widening over time, arrange a foundation inspection. We will help you repair these cracks and prevent the escalation of foundation issues that require costly repairs.

Separation at the ceiling and wall junction

Ceiling Cracks

Ceiling cracks are cracks that run along the length or are located near the intersections of walls. These cracks can indicate foundation movement or settlement. If you notice that both ceiling and wall cracks are in close proximity, it is a reason to arrange a detailed foundation inspection and repair plan. We can fix ceiling cracks with our swift repairs to safeguard your home’s overall stability.

Cracking and separation in a garage floor
Floor cracks, gaps or a misaligned garage door

Garage Foundation Problems

Early foundation problem indications are the most visible in your garage. As a homeowner, you spend a lot of time in your garage, and yet you can miss out on various spot signs that are right before your eyes. Some of the visible signs of garage foundation problems are:

  • Visible cracks in garage walls
  • Uneven garage floor
  • Garage door misalignment
  • Cracks in the garage floor
  • Gaps or separations between the garage structure and the main house

These signs can point to underlying foundation issues, such as foundation settlement or shifting. So, we offer prompt evaluation and repairs to avoid and eradicate further costly complications. Our foundation repair service is not limited to the problems mentioned above. These issues are just some of the frequent ones that we solve in this city.

Foundation Wall Cracks Tell Different Stories

The direction and pattern help explain what may be happening. Use this visual guide to describe what you see.

Horizontal cracks

It runs parallel to the ground.

Can indicate inward soil pressure or foundation movement. Bowing or widening calls for professional assessment.

Vertical cracks

It ascends or descends from the ceiling to the floor.

May be related to shrinkage or settlement. Track changes in width, displacement and water entry.

Stair-step cracks

Resembles a staircase pattern.

Usually found in masonry or brick walls. It can suggest foundation settling or upheaval that needs professional assessment.

Diagonal cracks

It traverses the wall at an angle.

Can indicate differential settlement or soil movement. Look for other changes nearby, including sticking doors or windows.

Watch for change: a widening crack, displacement, water entry, or a nearby door that starts sticking. Photos over time can help you explain what has changed.

Foundation Problems Often Start Below the Surface

Kansas City’s changing moisture conditions affect the soil around a home. The foundation responds when that support changes.

How a foundation moves matters as much as the crack it leaves.

It is normal for houses to shift and settle. However, too much movement can lead to permanent damage to the foundation. Given that the foundation is the integral support of your home’s structural integrity, it’s always best to turn to a professional foundation repair service provider. KC Waterproofing and Foundation Repair offers high-quality foundation repair in Kansas City across KS and MO.

We don’t just mend foundations; we repair, restore, and protect homes. With foundation repair solutions like piering, earth anchoring, basement waterproofing, polyurethane foam, sump pump installation, and more, we permanently redefine your home’s stability and structural integrity.

How Foundation Settlement Happens

A short KC explanation of movement beneath a home.

Poor Soil Conditions

Kansas City has a mix of clayey, loamy, and sandy soils, contributing to a diverse but challenging soil composition. When the soil expands and contracts during the rainy or winter season, the cyclical movement exerts pressure on the foundation, leading to shifts and settling issues.

Excess Moisture

Given that Kansas City experiences a mix of heavy rainfalls and dry spells, the soil naturally fluctuates in moisture. During heavy rains or inadequate drainage, the excess moisture causes the soil to lose its stability. So, when the soil takes in water and expands, it places additional stress on foundations due to hydrostatic pressure. To effectively fix these causes, our team always tailors foundation solutions through careful assessment (i.e., soil analysis, other visible foundation problem analysis, etc.). Not only this, we also implement effective moisture management solutions that act as a barrier to mitigate the impact of excess moisture on the foundation.

Plants & Soil Moisture

Plants absorb and release water vapor, affecting soil moisture levels, which impacts foundation stability. High transpiration periods cause the soil to dry out, resulting in contraction and potential separation from the foundation. Additionally, excessive rainfall saturates the soil, causing expansion and pressure against the foundation walls, resulting in issues like hydrostatic pressure or structural damage. While transpiration itself doesn’t directly cause foundation problems, its impact on soil moisture fluctuations around a building can significantly influence the foundation’s long-term stability.

Poor Construction

In a hurry to build your home early, your contractors can use poor construction practices without abiding by residential building standards. A client wouldn’t generally know this. Foundation issues can arise from poor construction, such as inadequate site preparation, suboptimal materials, or design flaws. Hence, the shortcuts that your contractors take to compromise the backbone of the structure will give rise to various foundation issues in the near future.

Foundation Repair in Kansas City FAQs

Answers about repair options, cost and next steps for your property.

How is the process of foundation repair carried out?

During foundation repair, the initial step involves assessing the specific issues that require fixing and repair. If needed, the installation of piers is carried out at the load-bearing strata and or bedrock. Piers can be installed either indoors or outdoors, but excavation is necessary for both methods. When installing outdoors, we utilize a small excavator with a depth capability of 8 to 9 feet. We excavate down to the bottom of the footing, prepare it for bracket attachment, and then install the hydraulic driving system. In Kansas City, the foundation steel pilings are driven into the bedrock at depths of 15 to 20 feet. Once the installation is completed, we affix our manifold system to each pier and lift the structure as much as the structural integrity will allow without causing more damage. This repositions the entire structure, closing cracks and ensuring proper alignment for doors and windows.

How to repair foundation cracks?

Since 1985, we’ve been repairing foundation cracks both inside and outside structures. Our process involves the setting of small injection ports every 6 to 8 inches along the crack, enabling us to inject material into the affected area. When injected under pressure, this material fills the crack from the inside to the outside. To secure this material, epoxy paste is applied externally to hold it in place while the liquid injection occurs. As the liquid concrete fills the capillary crack of the concrete, it forms a mechanical seal. Its pliable nature allows it to move and shift along with the foundation, while its adhesive properties bond the concrete edges. However, if there’s water infiltration from the wall’s floor, an interior drainage system or rapid floor drainage system is also required, not just a foundation crack repair. Our foundation crack repair work is backed by a lifetime guarantee and a transferable warranty.

What is the average cost of foundation repair in Kansas City?

In Kansas City, employing the steel piering method for foundation repair can range from $10,000 to $25,000, with an average overall foundation repair cost averaging around $15,000. Typically, minor foundation problems incur lower expenses compared to more extensive issues necessitating underpinning, piers, or structural solutions. To obtain an accurate estimate, it’s advisable to have a professional foundation repair contractor assess the specific issues on your property.

How do I know if I need foundation repair?

You can figure out if your house needs foundation repair or not by looking at some obvious signs of foundation problems, such as: Exterior or interior wall cracks Bouncing floors Wall and ceiling cracks Sticking ground or doors If you cannot figure this out, our foundation repair experts can help you.
