Foundation Walls Repairs in Philadelphia

Safe, engineered fixes for cracked, leaning, or water-damaged foundation walls

Your home’s foundation supports everything above it. When a foundation wall cracks, bows, leaks, or settles, it can threaten safety and value. At NK Construction & Design, we diagnose the root cause and deliver engineered, code-compliant repairs—including permits with Philadelphia L&I—so you can feel confident your home is secure.

Signs your foundation wall needs repair

  • Horizontal, vertical, or stair-step cracks in block/brick/concrete
  • Bulging or leaning walls; gaps at base or top (shear)
  • Water intrusion, efflorescence, or damp spots after rain
  • Uneven or sagging floors; doors/windows sticking above the basement
  • Crumbling mortar, spalling concrete, or rusted rebar “bleeds”
  • Lateral earth & hydrostatic pressure (poor drainage, heavy clay soils)
  • Settlement from weak/eroded soils or undersized footings
  • Freeze–thaw cycles and age-related deterioration
  • Surcharge loads (driveways, patios, retaining walls) near the foundation
  • Inadequate original reinforcement or workmanship

Why foundation walls fail

Repair options we provide

selected to fit your home

Crack Injection (Epoxy/Urethane)

Structural bonding (epoxy) or flexible water-stopping (urethane) for non-moving cracks.

Structural Tuckpointing & Masonry Stitching

Rebuild mortar joints and stitch cracked sections for brick/stone/block walls.

Carbon-Fiber Straps

Low-profile reinforcement for early-stage bowing and crack control.

Interior Steel Bracing (I-Beams/C-Channels)

Floor-to-framing posts to resist lateral loads where exterior access is limited.

Wall Anchors / Helical Tiebacks

Anchor into stable soil to pull/hold walls with more severe deflection.

Underpinning / Footing Repair

Stabilize settling walls with piers or micropiles when bearing capacity is inadequate.

Shotcrete & Rebar Retrofit / Partial Rebuilds

Restore capacity on heavily deteriorated sections.

Drainage & Waterproofing Upgrades

French drains, sump pumps, downspout extensions, grading to reduce water pressure.

We always recommend the least-invasive solution that meets engineering standards and local code.
