Richmond Home Foundation Repair

lifting and stabilizing a settled home in Richmond

 

About the Project

 

True Level Concrete was engaged to complete a comprehensive foundation stabilization and slab repair at a residential property located in Richmond.

The home (along with other homes in the area) was experiencing progressive settlement affecting both the foundation perimeter and interior slab, requiring a coordinated solution that addressed structural stability at its source while restoring interior floor performance.

Given the scale of movement and the risk of continued settlement, the project required a multi-system approach combining underpinning and slab stabilization.

Observed Conditions

  • Foundation settlement along multiple elevations
  • Interior slab settlement across garage, walkways, and living areas
  • Voids beneath slab and potential subgrade instability
  • Risk of further structural movement if left unaddressed

The layout drawing illustrates perimeter settlement zones and interior slab impact areas, confirming widespread influence rather than isolated failure.

 

Problem Recognition

 

Project Context

  • Structure Type: Existing residential home
  • Foundation Type: Concrete foundation with slab-on-grade interior
  • Scope: Full perimeter + interior slab zones
  • System Design: Pier locations around foundation perimeter

Site & Soil Conditions

The property is located in Richmond, an area known for:

  • Soft, compressible delta soils
  • High moisture content and water table influence
  • Reduced load-bearing capacity in native soils

 

These conditions significantly increase the likelihood of:

  • Differential settlement
  • Long-term soil consolidation
  • Loss of support beneath slabs and footings

 

Perceived Cause of Settlement

Settlement was most likely driven by:

  • Weak, compressible native soils typical of Richmond
  • Long-term consolidation under structural load
  • Moisture fluctuation affecting soil density and bearing capacity
  • Potential subsurface voids or disturbed soils

 

Client Priorities

  • Permanently stabilize the foundation
  • Prevent further structural movement
  • Restore interior slab performance
  • Avoid full foundation replacement
  • Ensure long-term confidence in the home

 

Products Installed

 

Foundation Stabilization

  • Push Piers with Pier Pads
  • Steel brackets + hydraulic installation system
  • Engineered load transfer to improved bearing strata

Slab Stabilization

  • PolyLevel® Injection
  • Applied across:
    • Interior slab
    • Garage
    • Driveway
    • Patio and walkways

Additional Services

  • Radiant heat scan (to protect embedded systems)
  • Plumbing scan (to identify potential contributing factors)

Solution Strategy

 

Why True Level Concrete

True Level was selected for its ability to:

  • Deliver full-scope structural repair (foundation + slab)
  • Execute complex underpinning with precision
  • Provide engineered solutions without full reconstruction
  • Coordinate trades (plumbing scans, engineering, excavation)

 

 

Installation Process

Foundation Underpinning

  1. Excavation at each pier location (1.5–3 ft depth)
  2. Installation of steel brackets at footing level
  3. Hydraulic driving of steel piers to load-bearing strata
  4. Load transfer and stabilization via synchronized lifting system
  5. Backfilling and compaction of excavated areas

Slab Stabilization

  1. Scanning for radiant heat and plumbing systems
  2. Drilling injection points across affected slab areas
  3. Controlled PolyLevel injection beneath slab
  4. Void filling, lifting, and stabilization
  5. Final patching of injection points

 

 

Results

Structural Outcomes

  • Foundation stabilized using 22 pier locations
  • Load transferred away from weak soils
  • Interior slab supported and voids eliminated

Performance Improvements

  • Reduced risk of further settlement
  • Improved floor elevation consistency
  • Stabilized structure for long-term performance

Issues Addressed

  • Foundation settlement
  • Interior slab movement
  • Subgrade voids
  • Soil instability

 

Long-Term Value

This project highlights the importance of addressing both foundation and slab systems together in settlement scenarios.

By combining underpinning with slab stabilization, the solution:

  • Restores structural integrity
  • Prevents continued movement
  • Extends the lifespan of the home
  • Eliminates the need for full replacement

The system also allows for future serviceability, meaning adjustments can be made if conditions change over time.
