Structural foundation repair and underpinning

    Structural Foundation Repair & Underpinning in Texas

    When foundation damage crosses into structural territory, advanced underpinning and pier systems provide permanent solutions.

    When a Home Needs Structural Repair

    Not all foundation cracks require structural intervention, but certain signs indicate serious damage that needs immediate attention:

    • Diagonal cracks wider than 1/4 inch, especially growing cracks
    • Horizontal cracks in foundation walls (major concern)
    • Floors sloping more than 1-2 inches across a room
    • Doors and windows severely out of square
    • Gaps between walls and ceiling/floor
    • Chimneys leaning or separating from structure
    • Foundation visibly settling or shifting

    Structural foundation repair addresses the underlying cause—unstable soil support—rather than just cosmetic damage. It prevents further movement and often lifts structures back toward level.

    Underpinning Methods We Use

    Steel Pier Systems

    Most common for Texas homes. We install helical or push piers beneath the foundation to transfer weight to stable soil layers deep underground, bypassing problematic surface soils.

    Mass Concrete Underpinning

    Traditional method involving excavating beneath the foundation in sections and pouring new concrete piers. Labor-intensive but effective for specific situations, especially accessible crawl spaces.

    Drilled Concrete Piers (Pressed Pilings)

    Deep concrete piers drilled into stable soil layers, then hydraulically pressed against the foundation. Provides maximum depth capacity for severe settlement or very unstable soils.

    Pier Systems for Major Movement

    Texas's expansive clay soils require pier systems specifically designed for our conditions:

    Helical Piers (Screw Piles)

    Steel shafts with helical plates screwed into soil like giant screws. Ideal for lighter structures and expansive clay conditions common in Texas. Installation monitored by torque readings to ensure proper depth in load-bearing soil.

    Push Piers (Hydraulic Piers)

    Steel pier sections hydraulically driven through unstable soil until reaching load-bearing strata. Uses the weight of the structure itself for installation. Best for heavier homes and when maximum lifting capacity is needed.

    Drilled Concrete Piers

    Large-diameter concrete piers drilled to depths of 10-30+ feet, extending well below the active soil zone affected by moisture changes. Maximum stability for severe subsidence or very poor soil conditions.

    Underpinning vs Full Replacement

    Structural underpinning is almost always more cost-effective than replacing a foundation:

    Underpinning Advantages

    • • Typically 30-50% cost of full replacement
    • • Less disruption to home and landscaping
    • • Faster completion (days vs weeks)
    • • Addresses root cause permanently
    • • Often covered by insurance

    When Replacement Needed

    • • Foundation completely deteriorated
    • • Major design flaws in original foundation
    • • Adding second story (need stronger foundation)
    • • Severe water damage beyond repair

    Our structural engineers evaluate your foundation and recommend the most cost-effective solution. In 95% of cases, underpinning provides a permanent fix without the expense and disruption of replacement.
