Concrete Leveling Madison, WI

Concrete Leveling


Concrete usually is one of the last things people want to spend money on. Unfortunately, sinking concrete typically causes additional and more expensive problems. The longer it goes unchecked, the more expensive it becomes to fix.

Concrete lifting, commonly called mudjacking, is a process of drilling through concrete and injecting material under the slab.

When done correctly, this lifts the concrete up to 3-4 inches. There are two types of concrete lifting, (traditional) mudjacking and urethane lifting (also called foam jacking). Here’s a more detailed comparison of the two.

The Concrete Lifting Process

All contractors differ, but when raising concrete we:

  1. Drill 1 to 4 dime-sized access points through each slab.
  2. Protect the surrounding concrete, insert a tap into each access point, and inject specialized foam (mudjacking contractors use thinned concrete mix).
  3. Verify the newly raised concrete pitch and level, patch holes, clean up, and finish lift in under 4 hours. Concrete lifted with foam is ready to use immediately.

Mudjacking vs Foam Concrete Leveling

Traditional Mudjacking

Lower Upfront Cost

The “mud” that’s injected under the concrete in traditional mudjacking is concrete thinned with sand and water. It is less expensive, but also far less resilient and 

Mudjacking has a high failure rate after 2-5 years.

Foam Concrete Lifting

A Permanent Solution
The overall process resembles traditional mudjacking, but high expansion foam is injected under the slabs instead of thinned concrete. Foam resists the causes of sinking which markedly extends its “lifting” lifespan.

Foam concrete leveling lasts long enough to extend the life of the concrete.

Foam Concrete Leveling Explained

Mudjacking & Foam Concrete Lifting Process

Step 1

Concrete Raising

Prepare the surrounding area to protect surfaces and expedite cleanup.

Drill injection points in specific locations to facilitate appropriately pitched final slope.

Step 2

Concrete Raising

For polyurethane concrete raising, polyurethane foam is injected under concrete and the foam expansion does the lifting. In traditional mudjacking, thin concrete is injected and machine-generated pressure does the lifting.

Step 3

Concrete Raising

Patch over the penny-sized holes. Concrete patches require time and weatherizing to closely match existing concrete color. Holes from concrete leveling with foam are smaller and less noticeable than holes from mudjacking.

Why Raise Concrete

The Damage Spiral

Concrete Protects Other Property

Concrete serves a critical water drainage function, stops heavy objects (like cars and buildings) from sinking into the ground, and provides flat walking paths. If not addressed, otherwise preventable water damage will greatly increase repair costs.

Water Drainage

Nothing Damages Like Water
Once concrete becomes damaged, it usually spirals and worsens at a quickening rate. Water that would otherwise be pushed away drains into cracks or the wrong direction. This can cause washouts, flooding, and other avoidable damage.

Safety and Ease

Ice Buildup and Tripping
In northern climates, cement sloping the wrong way usually means ice on walkways. Uneven slabs also jolt the back when shoveling snow. There’s a reason why businesses can’t have tripping hazards like cracks and lips in concrete. Nothing ruins a Christmas like a kid slipping or a grandparent tripping.

Foam Concrete Leveling

The Approach We Stand Behind

We exclusively lift concrete with foam. This is because we believe the process to be far more effective and a long term solution. 

We are also able to resurface concrete. The combination will take aged concrete and restore it to its original position and look. This often costs less, doesn’t damage surrounding property, and is more environmentally friendly than replacement. Thanks to the foam foundation, it’s also far less likely to sink over the years than new concrete.

Know YOUR Numbers

Planning with general numbers often leads to inaccurate estimations and budgets. That’s one of the many reasons we offer free estimates. Whether you need a quick fix or are planning for work next year, work with actual numbers specific to you.
