What is PolyRenewal™ Concrete Lifting Foam?

Sinking, cracked, or uneven concrete slabs don’t just look bad; they create tripping hazards and can lower your property’s value.

In the past, repairs involved mudjacking or full concrete replacement, both of which were messy, expensive, and invasive. Today, modern technology provides a cleaner and more durable alternative.

PolyRenewal foam concrete lifting utilizes advanced polyurethane injections to quickly and effectively lift and stabilize damaged concrete.

This page explores this innovative solution and explains why it has become the preferred repair method for South Carolina homeowners.

• Drill Small Holes: Our crew drills tiny, ¾-inch holes, about the size of a penny, into the concrete.
  
• Insert Ports: Injection ports are placed into the holes.
  
• Inject Foam: Using specialized equipment, polyurethane foam is injected beneath the concrete.

• Lift Concrete: The expanding foam fills voids, stabilizes the underlying soil, and gently lifts the slab.
• Cure Time: The foam cures within 15 minutes, allowing for safe use of treated areas on the same day.
  
• Patch Holes: The ports are removed, and the holes are sealed and smoothed for a clean finish.

• Lightweight and Strong: At around 4 pounds per cubic foot, PolyRenewal foam is significantly lighter than traditional fill materials (which weigh about 120 pounds). This makes it ideal for areas with unstable or weak soil. Despite its weight, PolyRenewal withstands heavy loads and provides more robust support over mudjacking.
• Water-Resistant: Once cured, PolyRenewal won’t wash away or erode, even after heavy rain or flooding.

• Environmentally Safe: The foam is chemically inert, meaning it won’t react with soil or release harmful substances.
• Fast-Curing: You can walk or drive on the repaired concrete about 15 minutes after installation.
• Non-Invasive: The compact installation equipment enables us to work in tight spaces with minimal disruption.

Uneven Driveway or Sidewalk

Concrete slabs may sink over time, especially in areas with expanding clay soils. Cracked driveways and sidewalks affect your home’s appearance and create safety hazards for your family.

Cracked Pool Decks

Concrete pool decks are prone to sinking and cracking due to water saturation and shifting soil. These uneven surfaces create dangerous trip hazards, especially around water, and take away from your home’s curb appeal. 

Sinking Porches or Cracked Patios

Cracked patios and sinking porches are signs that the soil beneath the concrete has shifted or settled. Moisture, poor drainage, and temperature fluctuations can erode the supporting soil, causing slabs to sink unevenly.

These issues create tripping hazards and structural concerns, particularly when the porch is connected to your home’s foundation. Gaps between steps or separating slabs often allow water to collect near the base of your home, worsening settlement and surface damage.
