Types of Foundation Problems We Fix 

It’s common for foundations to experience deterioration after years of wear and tear. Our team carries out a foundation inspection in Shawnee, KS, to discover the root cause of any problems. Afterward, we recommend suitable solutions that utilize advanced repair techniques.  We fix a variety of foundation problems, including the following:

Sloping and Uneven Floors

If you notice that your floors are beginning to feel saggy or bouncy, your foundation may be the cause.  Sloping and uneven floors are caused by several factors, including:

  • Excess moisture
  • Floor cracks
  • Excessive crawl space moisture
  • Poor construction
  • Shifting or settling ground
  • Expansive soil

If your floor is sloping or uneven, our professionals will discover the reason and recommend effective solutions.

Wall Cracks

Wall cracks can be alarming and dangerous for your foundation if you don’t repair them in time. It’s necessary to identify the types of cracks in your wall to gain a better understanding of the severity of the damage. The different types of wall cracks include the following:

  • Vertical cracks: The most common type of crack on a wall, vertical cracks run straight up and down. They are caused by thermal contraction and expansion in the structural element.
  • Horizontal cracks: These cracks appear on your property’s wall when there is expansive soil pressure against your foundation wall. It’s important to fix horizontal cracks on time, or else they will widen over time, damaging the wall.
  • Diagonal cracks: Diagonal cracks, also known as stair-step cracks, are caused by structural movement or increased pressure on the foundation. If you notice diagonal cracks, it’s important to have professionals inspect them right away.
  • Hairline cracks: Cracks of one to five millimeters are generally not significant. However, if there are wider hairline cracks, you should consider fixing them on time, or else they will lead to severe foundation problems.

Ceiling Cracks

Houses that have poor-quality construction or inadequately filled joints may experience ceiling cracks. If the cracks are bigger than 0.2 millimeters, this may indicate serious foundation issues. Ceiling cracks appear due to various reasons that include:

  • Bowing ceilings
  • Excessive weight
  • Drywall cracks
  • Shifting  soil

If you see numerous or large cracks in your ceilings, contact us immediately.

Garage Foundation Problems

If you have uneven floors, water leaks, a settling foundation, drainage issues, or a leaking roof in your garage, you may be seeing the results of foundation problems. It’s essential to repair your foundation on time, or else the overall structure of the garage and the functionality of the garage door may be compromised. Our team will assess the severity of your garage foundation problems and provide a suitable solution.

Foundation Crack Repair

Structural foundation cracks threaten your building’s structural integrity. Diagonal, vertical, and horizontal cracks on the foundation lead to long-term structural and foundation damage and deterioration. Foundation cracks are usually caused by the following:

  • Foundation settlement
  • Poor construction concrete shrinkage
  • Earthquakes
  • Poor drainage
  • Flooding
  • Extreme heat

Bowing Walls

If you don’t fix your bowing walls on time, they will eventually collapse, increasing the cost of repairs. In most cases, bowing walls are the result of structural failure or poor structural design. They are caused by excessive soil pressure, hydrostatic pressure, uneven flooring, bulging walls, and cracks in floors and walls.

Causes for Foundation Problems in Your Shawnee Home

Here, we’ve listed the primary causes of foundation failure or problems in Shawnee homes:

Poor Construction

Sometimes, foundation problems occur due to faulty or poor construction. Improper treatment of the soil during construction can lead to shifting, settling, and cracking of the foundation. Inadequate materials or uneven concrete slabs can also lead to foundation issues over time.

Poor Soil Conditions

The absorption of water or the weight of the house can cause the soil under your foundation to shift over time. Clay soil, in particular, expands when it absorbs water and shrinks when it dries out. This movement can destabilize a foundation and lead to water damage. If the soil was loose when the foundation was built, the foundation may settle more than is healthy. All of this can lead to foundation issues.

Excess Moisture

Moisture in the soil around your foundation can put pressure on the walls, leading to cracking and bowing. Water penetrating the walls can also cause leaks, flooding, and mold. If you notice signs of water damage, have experts inspect your basement and recommend solutions such as drainage solutions or sealant.  Excess moisture leads to issues such as:

  • Plumbing leaks
  • Drainage
  • Uneven floors
  • Musty oder
  • Sagging floors
  • Drywall cracks

Different houses have different foundation problems, so we will inspect your foundation and provide you with a customized solution. Our team will ensure that your house’s foundation is restored to its original condition.

Wall Anchoring

Wall anchoring is an effective solution for bowing basement walls.  Wall anchors stabilize and even straighten walls by restoring lateral strength and resisting the pressure of the surrounding soil. An anchor is installed in the ground near your home and attached to an anchor on your basement walls with rods.

Some of the benefits of wall anchoring include: 

  • Supports wall stabilization
  • Long-term solution
  • Prevents further movement of the wall
  • Compatible with other preventive measures

Some of the benefits of basement waterproofing include: 

  • Flood prevention
  • Energy efficiency
  • Enhanced property value
  • Improved air quality

Poly Fill

Polyfill, also known as the polyurethane foam injection method, is a process that repairs your foundation with minimal disturbance. This method is suitable for foundations that have sunk or settled. It is economical and quick compared to other traditional methods and reliable.

Some of the benefits of Polyfill include: 

  • The quick installation process
  • Cost-effective method
  • Non-invasive
  • Long-lasting result.

Sump Pump

A sump pump evacuates water from your basement to drainage away from your foundation. The pump forces out the water to avoid mold growth, water damage, and flooding. It automatically detects the level of rising water and redirects it to keep your foundation safe from water issues.

  • Reduces mold and mildew growth
  • Protects the basement from flooding
  • Safeguard your basement appliances
  • Protects the walls and paint of the basement

Mario came out to seal a crack on my stairs and fill a settlement crack in the basement. He was very professional and friendly. He did an amazing job and I was very impressed.
Didn't waste any time. I have a big problem and he told me from the beginning that they couldn't handle it. He helped give me some advice and direction... and did not try to sell me on something he knew they couldn't deliver. I appreciated his upfront honesty and advice.
They are a fantastic company and really went above and beyond to make sure we got the information we needed.
Mario was great! He very informative and helpful! I would highly recommend him!
Mario came out to check the sump pump. After cleaning the pit out and checking both the main and backup pump he wiped everything done and left the area cleaner than when he got there. Very friendly and knowledgeable guy!
Don Derry with KC Waterproofing has been our "go-to" foundation repair specialist since 2005! We have had him to our homes multiple times. The project always wraps up with us having peace of mind. This past time with 14 piers installed, was no exception. His crew was polite and respectful. They cleaned up our property perfectly at the conclusion of the project. I highly recommend this foundation repair company.
Tech was on time completed the repair as necessary, and the experience was great.
We recently had KC Waterproofing out at our home in North Kansas City, and I cannot say enough great things about Ryan Marshall and his team (Austin & Jacob). They worked at our property over the week of July 17/2025 - and absolutely blew us away with their professionalism, work ethic, and transparency.

Ryan took the time to thoroughly explain the problems we were facing, what caused them, and exactly how they were going to fix them. His honesty and willingness to go the extra mile truly set him apart.

Ryan and his assistant worked hard, were respectful of our home, and made sure everything was done right the first time. It's rare these days to find that level of care and craftsmanship. Because of professionals like Ryan, we’ll continue to turn to KC Waterproofing for future needs.

Highly recommend this company—especially if you get the chance to work with Ryan and his crew! When it comes to foundation issues we will always recommend KC Waterproofing. They have been in the business, are trusted, and will do the job correctly.
