Why Maryland Homes Experience Foundation Settlement

Foundation problems are common in Maryland due to soil composition and climate conditions.

Expansive and Moisture Sensitive Soils

Many areas of Maryland contain clay based soils that expand when wet and shrink when dry. This constant movement can create voids under foundations and slabs.

Unstable Soils

Maryland and Virginia has sandy soil along its coastline.  Sandy soil can become loose or poorly compacted making it unable to sustain weight over time.  When it shifts often causes foundations to settle. Sand drains quickly but a heavy rain can wash fines away, and any flowing groundwater can erode the soil under footings and create voids.

Water Intrusion and Drainage Issues

Poor drainage, downspout discharge near the foundation, and heavy rainfall can wash away supporting soil.

Freeze and Thaw Cycles

Seasonal temperature changes cause soil expansion and contraction, leading to gradual settlement.

Soil Erosion Beneath Slabs

Over time, small voids form under foundations and basement slabs, reducing structural support.

Our repair method addresses these underlying support issues without major excavation.

Signs Your Home Foundation May Need Repair

If you notice any of the following symptoms, your foundation may be settling:

  • Uneven or sloping floors
  • Cracks in interior walls or drywall
  • Gaps between walls and ceilings
  • Doors and windows sticking
  • Cracks in the slab floor
  • Separation at exterior brick or trim
  • Keystoning or stair step cracks along bricks or blocks
  • Sinking or Bowing Foundation
  • Sinking garage or basement floors

Early correction prevents further structural stress and more costly repairs.

What Is Polyurethane Polyfoam Injection?

Polyurethane Foamjection™ is a modern foundation stabilization method that lifts and supports settled concrete by injecting high density expanding foam beneath the slab.

The material is injected deep through multiple access points. Once injected, the foam expands to:

  • Fill voids beneath the foundation
  • Stabilize loose soil
  • Lift settled concrete with precision
  • Create long term structural support

Unlike traditional mudjacking, polyfoam is lightweight, moisture resistant, cures quickly and offers excellent longevity.

How Our Foundation Repair Process Works

Step 1: On Site Evaluation

We inspect the foundation, measure settlement, and identify voids or soil movement.

Step 2: Strategic Injection Planning

Our team determines precise injection points to achieve controlled lift and stabilization.

Step 3: Small Access Drilling

Small holes are drilled to install our deep injection rods at a determined length either through the slab or directly into the soil to access the void area beneath.

Step 4: Controlled Polyfoam Injection

Using our dual-component polyurethane, we can provide the stability needed to prevent settling. By pumping directly into the deeper soil layers, we can create a solid base layer that enables further repair through concrete raising techniques. High density structural foam is injected beneath the slab. The material expands to fill voids, bind soil and gently raise the foundation back toward level.

Step 5: Final Leveling and Verification

We monitor lift in real time and confirm stability before sealing injection points.

Foundation Problems Polyfoam Injection Can Solve

Polyfoam injection is ideal for:

Settled slab foundations
Basement slab sinking
Garage floor settlement
Voids beneath concrete slabs
Porch or addition settlement
Interior floor movement
For severe structural wall failures or deep foundation issues, additional structural methods may be required. We provide honest recommendations based on your specific situation.

Polyfoam vs Traditional Mudjacking

Polyfoam Injection

  • Lightweight material
  • Fast curing
  • Minimal mess
  • Precision controlled lift
  • Long term soil stabilization

Traditional Mudjacking

  • Heavier material
  • Longer cure time
  • Less precise lifting
  • Adds weight to unstable soil

Is Polyfoam Foundation Repair Permanent?

Polyurethane foam is water resistant and designed for long term stability.
When voids and soil issues are properly addressed, polyfoam injection
provides durable support.

In some cases, improving drainage around the foundation further protects
long term results. We evaluate each property individually to provide
the most effective solution.

Frequently Asked Questions

Most projects are completed in one day.

Polyfoam cures quickly. In most cases, normal use can resume the same day.

No. The process requires only small drilled access points.

Yes. The material used is engineered for structural support and is moisture resistant once cured.

If cracks are caused by slab settlement, stabilizing the foundation may prevent further cracking. Cosmetic repairs may still be needed.
