The Causes of Foundation Damage

If you notice signs of foundation damage, you may wonder about the cause. While some homeowners attribute the issues to initial construction practices, environmental factors, such as soil composition and weather conditions, are the primary culprits behind most foundation problems.

Soil composition varies by region, but all soils contain elements of sand, silt, and clay. In southern states, sandy soils with quick draining capabilities are most common, while expansive clay soils and silt soils with moderate drainage properties are prevalent throughout the country.

Regardless of the soil type, several factors contribute to foundation damage:

  • Inadequate compaction during the initial home construction
  • Soil expansion and softening during wet and rainy seasons
  • Soil shrinkage during droughts and dry seasons

According to, the top three causes of foundation problems are degradation of stem walls, foundation settlement, and foundation heave, all of which can be attributed to soil conditions. Foundation settlement occurs when the soil beneath the home shrinks and becomes unstable. Foundation heave happens when soil rises, usually due to settling in other areas.

Other factors contributing to foundation damage include:

Now that you know more about foundation problems and their causes, your next step is to repair the damage. The longer it persists, even if it appears minimal, the worse it will become. Cracks will expand, the settlement will worsen, and issues like uneven floors will become increasingly unsafe.

Our solutions include:

  • Carbon Fiber Straps: Low-profile carbon fiber straps, 10 times stronger than steel, are epoxied to cracked or bowing basement walls to reinforce them and prevent further movement.
  • Wall Repair System: For inward bowing walls that require straightening without exterior excavation, Groundworks uses the IntelliBrace™ wall repair system. Unlike conventional static I-beams, IntelliBrace™ supports are adjusted periodically to restore walls to their original positions.
  • Wall Anchors: Wall anchors permanently stabilize bowing foundation walls by counteracting hydrostatic pressure. Steel rods connect earth anchors to the basement’s interior wall plates. These components can be tightened using specialized equipment to straighten the walls over time. 
  • Crawl Space Support Jacks: Our IntelliJack™ crawl space support jacks reinforce and lift floors above the crawl space. We customize these supports to accommodate your crawl space’s height requirements.
  • Foundation Piers: Foundation piers permanently stabilize and potentially lift foundations to their original position. These piers include helical piers, push piers, and slab piers.

Foundation repair is not a DIY project and should be left to professionals. A professional inspection and repair process ensures a comprehensive, long-term solution.

With locations in over 30 states, Groundworks offers foundation repair and waterproofing solutions nationwide to permanently protect your home’s safety, integrity, and value.
