Concrete Lifting Explained: Answers to the Most Common Questions About Fixing Sunken Concrete

When concrete begins to sink, crack, or shift, it’s more than a cosmetic problem — it’s a sign of deeper soil instability beneath the surface. Uneven slabs can create trip hazards, drainage issues, and long-term property damage if ignored. At Level Best Northwest, we use Eco-Rise polyurethane foam lifting technology to restore concrete safely, efficiently, and without demolition. Below, we answer the most common questions homeowners and business owners ask about concrete lifting so you can make an informed decision about protecting your property.

Q1: What is concrete lifting and how does it work?

Concrete lifting is a non-invasive repair method that raises and stabilizes sunken concrete slabs. Level Best Northwest uses Eco-Rise polyurethane foam, which is injected beneath the surface to fill voids, lift slabs, and prevent further settling — all without demolishing the existing concrete.

Q2: What causes concrete to sink in the first place?

Common causes include soil erosion, poor compaction, moisture changes, or voids created by plumbing leaks or pests. In Central Washington, freeze-thaw cycles and expanding clay soils are major contributors.

Q3: Is concrete lifting better than replacing concrete?

In most cases, yes. Lifting is faster, cleaner, and significantly more affordable than replacement. It requires no demolition, produces minimal disruption, and is usually completed in one day.

Q4: What types of projects are ideal for concrete lifting?

Concrete lifting works for:

• Driveways and sidewalks

• Garage floors and patios

• Warehouse slabs and commercial entrances

• Pool decks and crawl spaces

  
  

If the concrete is structurally sound, lifting is usually the best choice.

Q5: How long does concrete lifting last?

When done with Eco-Rise foam, results are long-lasting because the foam is waterproof, lightweight, and stable. It won’t break down or wash away like traditional mudjacking materials.

Q6: How much does concrete lifting cost?

Costs vary by project size and severity but are typically 30–50% less than full replacement. Level Best Northwest provides free on-site estimates to evaluate each project’s needs.

Q7: When is the best time to lift concrete in Central Washington?

Fall and spring are ideal, before extreme cold or heat set in. Lifting before winter helps prevent more sinking from freeze-thaw damage.

Q8: Why choose Level Best Northwest for concrete lifting?

With local expertise, advanced Eco-Rise technology, and deep community ties, Level Best Northwest understands the region’s unique soils and climate challenges. Their methods are proven to restore safety, protect property value, and prevent costly future repairs.

Q9: What is Eco-Rise foam and how does it work?

Eco-Rise is a two-part, closed-cell polyurethane foam system designed specifically for concrete lifting, soil stabilization, and void filling. It’s a lightweight, minimally invasive alternative to traditional mudjacking that provides long-lasting stability without the mess or heavy equipment.

Here’s how the process works:

1. Drilling: Technicians drill one or more small (⅝") holes through the sunken slab.

2. Injection: A two-part liquid resin is pumped through the holes, where it mixes and begins to expand.

3. Expansion: The foam fills hidden voids, compacts weak soil, and gently lifts the slab back into position.

4. Curing: Within 15–30 minutes, the foam cures to 90–95% of its full strength, allowing the area to be used again almost immediately.

   
   

Key Benefits of Eco-Rise Foam:

• Lightweight: Adds minimal stress to the soil beneath.

• Fast: Most projects are completed in a single day.

• Minimally invasive: Small drill holes (⅝") mean little to no disruption of landscaping.

• Cost-effective: Less expensive and faster than replacement.

• Permanent: The foam doesn’t shrink, settle, or lose density over time.

• Environmentally friendly: Uses renewable materials and keeps concrete out of landfills.

  
  

This innovative technology allows Level Best Northwest to deliver stronger, cleaner, and longer-lasting results compared to traditional repair methods.
