Concrete Lifting vs. Replacement: Which Fix Makes the Most Sense?

When concrete starts to sink, crack, or settle, most people assume the only solution is to tear it out and start over. But in many cases, lifting and leveling your existing concrete is a smarter, faster, and far more cost‑effective option.

We put together a short educational video that breaks down the differences and helps you understand which solution is right for your property.

Why Concrete Sinks in the First Place

Concrete doesn’t fail because the slab is weak — it fails because the soil underneath it changes. Common causes include:

  • Soil erosion from poor drainage
  • Freeze–thaw cycles
  • Poor compaction during construction
  • Water washing out the base
  • Organic material under the slab breaking down

When the ground shifts, the concrete follows. The good news is that the slab itself is often still in great shape — it just needs support.

Concrete Lifting: A Smarter, Faster Solution

Concrete lifting uses high‑density polyurethane foam to raise and stabilize the slab from below. It’s a clean, efficient process that solves the root cause of the problem.

Benefits of Lifting

  • Cost‑effective — often 50–75% less than replacement
  • Fast — most projects take 1–2 hours
  • Minimal downtime — walk or drive on the slab the same day
  • Clean process — no demolition or debris
  • Long‑lasting — foam won’t wash out, rot, or settle
  • Eco‑friendly — restores existing materials instead of sending them to a landfill

Ideal for:

  • Driveways
  • Sidewalks
  • Patios
  • Garage floors
  • Pool decks
  • Commercial walkways
  • Warehouse slabs

When Replacement Makes More Sense

While lifting solves most settlement issues, replacement may be necessary if:

  • The concrete is severely cracked or crumbling
  • The slab has major structural damage
  • Large sections are missing
  • The surface is beyond cosmetic repair

If the slab is intact but uneven, lifting is almost always the better choice. If the slab is falling apart, replacement may be the right call.

How to Decide What’s Right for Your Property

The best solution depends on:

  • The condition of the slab
  • The cause of the settlement
  • Your budget
  • How quickly you need the area usable
  • Whether the issue is residential or commercial

Our team evaluates the concrete, the soil conditions, and the drainage around the area to recommend the most effective long‑term fix.
