Homes with basements rely on foundation systems to support their structure and resist the pressure of the surrounding soil. Because these foundations extend below ground level, they are exposed to changing soil and moisture conditions that can affect their stability over time.
Learn the common causes of below-grade foundation damage and the proven solutions that help protect your home.
Below-grade foundations, such as basement foundations, extend partially or fully below ground level. Because they are surrounded by soil, they must support the home while resisting the pressure and moisture that can build up around them over time.
Below-grade foundations are exposed to forces that can affect their stability. Common causes of damage include hydrostatic pressure, soil heave, and movement. These unstable conditions often lead to cracks, bowing walls, water intrusion, and other structural concerns.
We address below-grade foundation damage with proven repair solutions designed to restore stability. Depending on the issue, repairs may include foundation piers, wall reinforcement systems, or waterproofing systems that address the underlying cause of the damage.
Hydrostatic Pressure
Hydrostatic pressure develops when excess groundwater builds up around your foundation and pushes against basement walls and floors. Poor drainage and improper water management can increase this pressure, leading to cracks, bowing walls, and water intrusion over time. Left unaddressed, these issues can compromise the structural integrity of your foundation and create ongoing moisture problems.
Soil Heave
Soil heave occurs when moisture causes the ground beneath a foundation to expand, pushing it upward. This often happens when dry soil absorbs water from heavy rainfall, flooding, or plumbing leaks. Clay-rich soils are especially prone to swelling as moisture levels increase. As the ground expands unevenly, it can lift portions of the foundation, leading to cracks in the foundation, walls, floors, and other areas of the home.
Soil Movement
Soil settlement occurs when the ground beneath a foundation compresses or loses strength over time. Factors such as fluctuating moisture levels, inadequate soil compaction, and the weight of the home can contribute to settlement. As the supporting soil shifts or settles unevenly, portions of the foundation may sink, leading to cracks, structural movement, and other signs of damage.
JES reinforces below-grade foundations with engineered pier systems that stabilize and, when possible, lift settled structures. Depending on the home’s needs, we may recommend helical piers, slab piers, or push piers for long-term support and stability.
Wall repair systems stabilize cracked, bowing, and buckling walls and, in some cases, help restore them to their original position. JES experts may recommend wall anchors, carbon fiber reinforcement, or the IntelliBrace™ wall repair system.

Basement waterproofing systems, including interior drainage systems, vapor barriers, and sump pumps, help manage groundwater and protect below-grade spaces from moisture intrusion. These components work together to collect and redirect water away from the foundation before it enters the home.
