Cracks in Basement Floor 

When your basement floor resembles a seismic aftermath, it clearly signifies trouble. Neglecting basement floor cracks jeopardizes structural integrity and invites water infiltration. 

Our team at Baker’s Waterproofing has years of experience and tools to handle these cracks effectively. Homeowners in Pennsylvania trust our quality basement repair, basement waterproofing, and foundation repair services and solutions. 

By the end of this page, you’ll understand why basement floor cracks occur and how to put an end to them. 

What Are Basement Floor Cracks? 

Basement floor cracks are any gaps or fractures in the concrete floor. These cracks often result from various pressures and forces compromising the concrete’s integrity. 

Although not all cracks indicate an immediate threat to your basement or foundation, prompt attention is necessary to prevent water seepage and further deterioration. 

Common Causes of Basement Floor Cracks 

Numerous issues can cause cracks in basement floors. Our experienced team can help you identify these factors during a thorough inspection: 

Soil Movement 

Moisture fluctuation beneath your home can lead to soil movement over time, resulting in cracks. For instance, rainfall can trigger soil erosion under your foundation. 

As the soil erodes, your basement settles, causing the concrete floor to crack as it adjusts to the shifting ground. 

Expansive Soils 

Certain soil types—namely clay soils—expand when saturated and contract when dry, as pictured here. If your home is built on clay soil, the resulting expansion and contraction cycles can cause the basement floor to crack. 

Hydrostatic Pressure 

 Water buildup beneath the basement floor exerts upward pressure, leading to cracks. These cracks expand over time, especially if water pressure remains consistent. Concurrently, water infiltration can exacerbate the situation by further eroding the concrete. 

Concrete Shrinkage 

Freshly poured concrete undergoes a curing process that can cause it to shrink. Uneven shrinkage can lead to cracks. 

While these cracks are usually thin and may not compromise structural stability, they can allow water intrusion if they traverse the slab depth. 

Heavy Loads 

Storing heavy items in the basement can exert excess stress on the floor, potentially leading to cracks—particularly if the floor wasn’t designed to bear such weight. 

Understanding the causes of basement floor cracks is vital for selecting appropriate repairs. At Baker’s Waterproofing, we offer solutions tailored to address these underlying issues. 

Can Cracks in Basement Floors Be Fixed? 

Absolutely! As basement and repair techniques evolve, replacing the entire basement floor isn’t always necessary when cracks appear. 

It’s important to note that the severity of floor cracks varies based on factors like size, pattern, nature, and location. Our thorough inspection process ensures that we provide customized solutions for each specific crack. 

How Baker’s Waterproofing Addresses Cracks in Basement Floors 

Our proven approach has earned the trust of countless homeowners throughout Pennsylvania. Here’s how we tackle basement floor cracks: 

Comprehensive Assessment 

We thoroughly assess each crack, documenting its dimensions, location, pattern, and width. This comprehensive approach helps us determine whether factors like soil movement, hydrostatic pressure, or heavy loads are contributing factors. We also examine your home’s foundation and soil conditions. 

Weight Redistribution with Foundation Piers 

If your basement floor sinks or becomes uneven due to shifting soil, we strategically install foundation piers deep into the ground until they reach more stable load-bearing soil. 

These piers shift the weight from the unstable floor onto themselves, realigning the basement floor and ensuring long-term stability. 

Addressing Wall Cracks 

The same forces that lead to floor cracks can also lead to wall cracks. If your basement is affected by both issues, it is also wise to address the wall cracks. 

Baker’s Waterproofing offers a range of wall repair solutions, including: 

Each solution is engineered to withstand heavy loads and prevent leaking water and structural damage in the basement. 

Installing Basement Waterproofing Measures 

We install water management solutions in your basement to counteract hydrostatic pressure and redirect incoming moisture. These include interior drains and a sump pump to intercept leaking water and redirect it away from the basement. 

Our toolbox includes top-quality solutions tailored to your basement’s unique needs, while our extensive experience ensures the long-lasting integrity of your basement floor. 


The Importance of Promptly Addressing Floor Cracks 

Delaying floor crack repairs can escalate minor issues into major foundation problems, including: 

  • Cracks can rapidly expand due to ongoing pressures. 
  • Widening cracks increase the risk of water seepage, potentially leading to mold growth and soil erosion. 
  • Neglected cracks can contribute to sagging, uneven floors and structural damage. 
  • Postponing repairs can result in higher costs, particularly if water damage occurs. 

Your home’s stability hinges on the health of its foundation. Don’t disregard signs like floor cracks.  Baker’s Waterproofing provides access to swift and effective solutions beyond surface-level fixes, fortifying your basement long-term.

Not necessarily. While some cracks are caused by natural concrete shrinkage, others can indicate underlying foundation issues. Professional assessment is crucial to determine the cause and necessary action. 

We do not recommend DIY repairs for basement floor cracks. These are merely temporary fixes that can become costly and dangerous. Accurately diagnosing the causes and applying effective repairs requires specialized knowledge and tools. 

The duration of the repair process for basement floor cracks can vary depending on the extent of the damage and the chosen repair method. Baker’s Waterproofing will assess your situation and provide an estimated timeline during the consultation.
