Understanding Foundation Problems

Foundation problems can manifest in various ways, often starting subtly and progressing if not addressed promptly. Homeowners should be vigilant in identifying these early warning signs to prevent further damage and costly foundation repairs.

Common Signs of Foundation Issues

  • Cracks in Walls and Floors: Hairline fractures can appear in drywall, ceilings, or concrete floors, indicating shifting or settling foundations. Over time, these cracks may expand if the underlying problem is not resolved.
  • Doors and Window Misalignment: Difficulty in opening or closing doors and windows can result from foundation movement causing frames to become misaligned. This is often accompanied by visible gaps around the frames.
  • Uneven or Sloping Floors: Noticeable dips or slopes in flooring may suggest foundation settling or structural issues. These can also lead to squeaky or creaking floorboards.
  • Bowing or Leaning Walls: Walls that bulge or lean inward are often a sign of external pressure on the foundation, potentially from soil expansion or hydrostatic pressure.
  • Water Intrusion: Moisture in basements or crawl spaces can indicate foundation cracks or inadequate waterproofing, leading to mold growth and structural damage.
  • Gaps Between Walls and Ceilings: Visible separation between walls and ceilings is another indicator of foundation instability.

    Causes of Foundation Issues

    Several factors contribute to foundation problems, particularly in the Raleigh and Durham regions:

    • Soil Composition: The prevalent triassic clay soils in this area expand when wet and contract when dry, exerting pressure on foundations and causing movement. This “clay bowl effect” is a common issue in North Carolina.
    • Hydrostatic Pressure: Excessive moisture accumulation around the foundation increases soil pressure, leading to cracks and leaks. Prolonged exposure to water weakens the foundation over time.
    • Poor Drainage: Inadequate drainage systems can result in water pooling near the foundation, exacerbating soil movement and foundation stress.
    • Tree Roots: Nearby trees with extensive root systems can draw moisture from the soil, causing it to contract and affect foundation stability. Roots can also physically invade foundation walls.
    • Seasonal Weather Changes: North Carolina’s freeze-thaw cycles can worsen existing cracks and increase soil movement, further destabilizing the foundation.

    Our Comprehensive Foundation Repair Services

    At Cornerstone Foundation Repair & Waterproofing, we provide a range of services to address all foundation-related concerns. Our team uses state-of-the-art technology and proven techniques to ensure the longevity and stability of your home.

    1. Foundation Repair and Underpinning

    • Helical Piers: Ideal for stabilizing structures located in North Carolina, helical piers are screwed into the soil past the active layers of clay to permanently stabilize or lift your footings. The benefit to a helical is that it is placed into the soil independently of the home and can be mechanically driven past any premature hard layers of soil unlike a push pier.

    2. Wall Stabilization

    • Helical Tiebacks: Used to counteract external soil pressure, wall anchors stabilize bowing or leaning walls.. They are an excellent solution for walls showing signs of lateral movement.
    • Carbon Fiber Strapping: A non-invasive method to strengthen and stabilize cracked or bowing walls using high-strength carbon fiber straps. This solution is quick to install and highly durable.
    • Steel Soldier Beams: High carbon steel I-Beams are engineered to stabilize your bowing wall by being placed tight to the bowing wall and secured to the framing above and into a footing below.

    3. Crawl Space Repair, Drainage and Encapsulation

    • Structural Repairs: Addressing issues like sagging floors by reinforcing or replacing damaged joists and beams. Our team ensures that the crawl space structure is secure and resilient.
    • Interior Crawlspace Drains: The ultimate solution to water infiltration into your crawlspace. An 8-12” trench is excavated around the inside face of your foundation wall to expose the top of the footing. A laser level is then utilized to determine the low point of the footing in order to find the perfect placement for the sump basin (if needed). A sock wrapped drain tile is then placed on top of the footing and routed to a new sump basin or to a daylight drain exit in the foundation wall. Washed #57 stone is backfilled into the trench even with the surrounding soils. A new 10 mil vapor barrier is then placed on the soils extending to the foundation walls and tight to the interior support piers.
    • Crawl Space Encapsulation: Sealing crawl spaces with vapor barriers to prevent moisture intrusion, improve air quality, and enhance energy efficiency. This process also helps reduce utility costs and prevents pest infestations. An Aprilaire dehumidifier is used to keep humidity to a minimum and is used to create the optimal airflow needed inside the crawlspace.

    4. Basement Waterproofing

    • Interior Drainage Systems: Cutting the concrete slab and placing drainage channels and sump pumps to manage water intrusion effectively. This system collects and redirects water before it can cause damage.
    • Exterior Waterproofing: Excavating the exterior basement walls and applying protective coatings and membranes to the exterior foundation walls to prevent water penetration. This is the ultimate protection for your masonry walls and provides an additional layer of defense against moisture.

    5. Concrete Lifting and Leveling

    • Polyurethane Foam Injection: A minimally invasive technique to lift and level sunken concrete slabs, driveways, and sidewalks. This process restores the appearance and safety of your property while preventing further damage.
