Foundation Heave

A house that features flooring riddled with gaps, cracks, or holes is far from ideal. 

The presence of cracks in your foundation walls or floors, uneven slab floors, and settling parts inside your home may signal a serious structural concern known as foundation heave. This issue compromises the structural integrity of your home and poses a significant threat to the safety of your family. 

With over 45 years of experience, our team at Dry Pro Foundation & Crawlspace Specialists has the expertise to diagnose and address foundation heave issues, helping to prevent further damage. 

By the end of this page, you will have a deep understanding of the causes and problems related to foundation heave, and the ways professional repairs can safeguard your home. 

What Is Foundation Heave? 

Foundation heave is characterized by the upward movement of a structure’s foundation or slab, a phenomenon triggered by the expansion or swelling of the underlying soils, typically due to moisture increase or freezing conditions. 

The resulting symptoms might include: 

Wall Cracks 

Wall cracks are fractures that appear on the surface of walls, often as a result of the foundation heave. They can appear vertically, horizontally, or diagonally, and may widen over time, indicating the ongoing movement in the foundation. It is essential to monitor the size and shape of these cracks regularly as it can provide valuable information on the severity of the foundation heave, and to consult with a specialist if you observe significant changes. 

Floor Cracks 

Floor cracks are breaks or splits that occur on the flooring surface, which can be seen in various forms, such as hairline fractures or gaping holes. These often originate due to the changing pressure and conditions in the ground underneath the floor. The soil can expand due to moisture, pushing the foundation upwards, resulting in cracks in the floor. They might appear in isolated areas or spread across a larger surface and can be a trip hazard as well as a sign of a deeper structural issue. Keeping an eye on the development of floor cracks can help in understanding the urgency and the type of intervention needed. 

Uneven Slab Floors 

Uneven slab floors refer to an inconsistent level on the flooring, where some sections may be higher or lower than others. This happens due to the irregular movement in the foundation, where one part experiences heave while another doesn’t. Walking on an uneven floor, you might notice a sloping sensation, or see that furniture does not sit evenly on the surface. It not only creates a safety hazard but also shows potential underlying issues with the foundation. Utilizing a level tool can help in assessing the extent of the unevenness, which should be addressed promptly to prevent further complications. 

Evidently Raised Foundation 

An evidently raised foundation refers to visible and noticeable lifting of the home’s foundation above its original position. This is a serious sign of foundation heave, where the soil beneath the foundation swells to such an extent that it pushes the foundation upwards. This is easily noticeable in the exterior of the home, where you might see the foundation appearing higher than the surrounding ground level, or in severe cases, you might notice the entire structure leaning or tilting. This requires immediate attention and intervention from a foundation repair specialist, as it poses a significant risk to the structural integrity and safety of the home. 

Each of these signs of foundation heave is a call to action to seek professional advice and intervention, to maintain the safety and value of your home. 

Contrary to foundation settlement that involves sinking, foundation heave propels portions of your foundation upwards. This is especially common with slabs, which lack sufficient weight to resist the force exerted by swelling soil.

What Causes Foundation Heave?

Understanding the causes of foundation heave is essential. Here are several factors: 

  • Initial Construction: New homes might face soil stabilization issues, making them prone to foundation heave in the initial years. 
  • Soil Type: Soils like clay that absorb excess moisture can swell, exerting pressure on foundation walls. 
  • Poor Drainage: Inadequate systems can aggravate the problem, leading to water pooling around your home’s foundation. 
  • Changing Weather: Fluctuations in weather, especially freezing temperatures followed by rainfall or snowfall, can induce soil expansion. 
  • Tree Roots: Roots from nearby trees can displace soil and reach beneath the foundation, causing it to rise. 
  • Settling Issues: Sometimes, a part of the foundation settling more than others can give an appearance of heaving in different sections. 

Identifying these factors early aids in crafting the perfect solution.

  • Slab Piers: These are installed beneath your home’s foundation into sturdy soil, crafted especially for homes with slab foundations. 
  • Wall Reinforcement: Sometimes heaving foundations necessitate reinforcement and repair of basement walls using solutions such as carbon fiber straps, steel I-beams, wall anchors, or channel anchors
