How We Can Help

Calling us as soon as you notice your driveway beginning to drop, or develop voids underneath the concrete, will save you as much money as possible. 

 

The smaller the height of the drop or void, the cheaper your repairs will be.

When we mudjack, we pump our specially designed Portland cement and soil slurry mix underneath your concrete at a very high pressure, pushing down the settling soil. This high pressure compacts the soil underneath your driveway, preventing further settling as much as possible.

 

The sooner you call Boss Mudjacking, the sooner we can fix any small issues you may have, and prevent them from developing and causing much more costly damage in the future.

Some Examples of Common Driveway Issues

Sinking at Garage Approach

The Cause

When builders dig the foundation for a home, this area is wider than the building itself.

The footings are then back-filled, and this soil is more prone to settle over time.

Garage entrances are high-traffic areas, meaning the concrete is even more likely to drop.

The Signs

Hairline cracks may appear every 12-18 inches at the top of your driveway, perpendicular to your garage doors.

This is the upward pressure of the rebar struggling to hold unsupported concrete.

Looking at your driveway side-on, you may see a gap between the bottom of the concrete and the soil underneath it. 

The Fix

At Boss Mudjacking, we use a 1500psi pump (pressure washers run at around 1200psi).

This pushes down any settling soil to compact it as much as possible.

We then continue to pump our slurry mix to fill any void, and then push the concrete back upwards to its original height.

Uneven Driveway Panels Can Cause Cracks

When soil settles under concrete, it does not necessarily all settle at the same rate. This means that as the soil under a large panel of concrete in your driveway settles down, one side of the concrete may be more supported than the other. This creates a large amount of pressure across the panel, and can sometimes cause a crack as the side with more settling, and therefore less support, submits to gravity and its own weight, and drops down.

The images below show how the beginning stages of a driveway settling unevenly. We fixed the issue early and prevented any further damage that would have occurred if the homeowners had let the concrete continue to settle.

The Cause

When soil settles under concrete, it doesn't necessarily all settle at the same rate. 

As soil under a large panel in your driveway settles, one side of the concrete may be more supported than the other.

This creates pressure across the panel, which can lead to large cracks and breaks as gravity takes hold.

The Signs

When looking at your driveway side-on, you may notice a gap between the bottom of the concrete and the soil underneath it. 

You may also notice a hollow sound if you bounce a basketball on the concrete. You can also test by dropping a golf ball and listening for an echo. 

Hairline cracks may appear. Calling us early will help to prevent these turning into large cracks or even breaks in the concrete.

The Fix

At Boss Mudjacking, drill holes in strategic places in your driveway to maximize the areas that our slurry mix will reach and support. 

We always pump as much material as possible to make sure that every area of your driveway is fully supported. Sometimes you will even notice a little overflow out the sides, so you know it's really full!
