Cracks in Basement Floor 

If you observe cracks on your basement floor, take them seriously. They may indicate a more significant foundation issue that could worsen and cause flooding and mold growth. 

With our insights, you’ll understand why floor cracks occur, their level of severity, and the most effective repair solutions. Follow our advice to eliminate basement floor cracks and prevent damage to your foundation. 

What Are Cracks in Basement Floor? 

Cracks in the basement floor occur when concrete slabs develop fractures or fissures. While some minor hairline cracks aren’t always structural, larger, spreading cracks signal a foundation issue. Regardless of size, cracks allow moisture to enter through the concrete floor, leading to water in your basement, dampness, and potential mold growth. Over time, unaddressed cracks lead to sinking floors, foundation instability, and complete structural failure. 

The most severe basement floor cracks extend entirely through or along slab joints. These structural cracks indicate substantial pressure on and movement of the foundation. Perimeter cracks near walls also tend to suggest foundation settlement. 

What Causes Cracks in Basement Floor?

Cracks in basement floors stem from various sources, but improper foundation support is often the primary reason. Specific causes may include: 

  • Excessive hydrostatic pressure on foundation: Especially after rain, water pressure can build up around the foundation and cause it to shift, leading to cracks in the basement floor. 
  • Foundation settlement into soil: Over time, the soil beneath the foundation can shift or settle, causing the foundation to sink and crack. 
  • Frost heaving: During the winter, water in the soil can freeze and expand, causing the foundation to heave and crack. 
  • Invasive tree roots: Tree roots can infiltrate the soil beneath the foundation and cause it to shift and crack. 
  • Weak or unstable fill material: If the soil beneath the foundation is not compacted correctly, it can shift and settle gradually, causing the foundation to crack. 
  • Concrete deterioration: Over time, concrete can deteriorate due to exposure to moisture or other environmental factors, leading to cracks in the basement floor. 

These forces stress the foundation over time. As cracks develop, water penetrates the basement, accelerating cracking and foundation damage

Can You Fix Cracks in Basement Floor?

Yes! Innovative Basement Authority’s professionals utilize foundation repair techniques to resolve basement floor cracks permanently. DIY basement repairs may seem convenient initially, but they rarely provide permanent solutions. Our professional technicians will: 

  • Use engineered products explicitly designed for longevity. 

How We Repair Cracked Basement Floors

Repairing cracked basement floors involves structural stabilization and basement waterproofing solutions.  

Innovative Basement Authority uses several techniques to repair cracked basement floors. These include: 

  • Installing interior drainage systems and sump pumps: These systems collect water that seeps into the basement and directs it away from the home, preventing flooding and water damage. 
  • Waterproofing basement walls/floors to prevent moisture intrusion: This involves applying a vapor barrier to the walls and floors of the basement to prevent water from seeping through and causing further damage. 
  • Applying fresh concrete to fractured slabs for a smooth finish: Once the foundation has been stabilized, the cracks in the floor can be filled and covered with a new layer of concrete for a smooth and even finish. 

These techniques allow Innovative Basement Authority to permanently repair cracked basement floors and prevent further foundation damage. 

Innovative Basement Authority handles your entire cracked floor repair, from inspection to finished product, using top-rated materials so you have total peace of mind.
