Timely Concrete Repairs Prevent Serious Problems

A sinking concrete slab is always worth fixing, whether in your basement, garage, driveway, or patio. When a concrete slab starts to sink, it signals a possible problem with the soil underneath — often erosion or poor compaction. Sinking slabs can crack and cause unsafe, uneven walkways, leading to trip hazards.

PolyLevel® Is a Fast, Proven Solution for Sunken Concrete.

PolyLevel is a proprietary polyurethane foam that is injected beneath sunken concrete to raise sinking slabs in and around your home. PolyLeveling not only restores the beauty and safety of sunken concrete but also addresses the underlying factors that caused it to sink in the first place.

What causes concrete slabs to sink?

When all or part of a slab sinks, it's usually due to one of two conditions.

  • Depending on the supporting soil's composition and condition, and how the concrete was installed, it may compress under the slab's weight. Uneven compression or settlement leads to empty spaces or voids in the soil. Since concrete is heavy, concrete slabs will always sink when voids are underneath.
  • Heavy rainfall and other water flow can wash away some of the soil under the slab, causing it to sink into the resulting void. This is why you need a concrete repair method that not only levels your slab but also addresses the underlying conditions that caused it to sink in the first place.

Signs of Sinking Concrete

What does it look like when a concrete slab begins to sink? You may notice one corner of a driveway sloping or concrete stairs pulling away from your home's foundation. One or more cracks in a walkway, patio, or sidewalk can also signal sinking concrete. The extent of the problem can be subtle or dramatic and involve one slab or many. Regardless, uneven between slabs make for unsafe walking, biking, or driving. The underlying issues of erosion and uneven soils can worsen with changes in temperature and precipitation, further reducing the stability of your concrete.

Why You Shouldn't Ignore Your Sinking Concrete

The problem won't get better without concrete repairs. Over time, sinking concrete leads to:

  • Serious trip hazards, especially during icy or rainy weather
  • Unattractive walkways, stairs, pool decks and driveways
  • Water drainage or pooling, which can often lead to further concrete cracking or foundation structural issues
  • An overall decline in your property value

Methods for Repairing Sinking Concrete Slabs

Concrete Replacement
Concrete replacement

Sinking slab repair strategies should address the cause of your sunken concrete. Some concrete contractors recommend repairing a sinking slab by demolishing the damaged area and pouring new concrete. As a concrete slab repair method, concrete replacement poses some disadvantages, including:

  • Concrete replacement is expensive and complicated: it can take several days for the fresh concrete to harden and cure before the slab or slabs are ready to be used again.
  • Concrete replacement doesn't address the problem of weak soil conditions, which means the soil is likely to compress again under the weight of the new slab. A shortcut repair sometimes involves adding more concrete to even out an uneven slab, but this approach adds even more weight to the soil below. Adding weight without addressing underlying soil issues increases the risk that the concrete slabs on your property will sink again.
Mudjacking
Mudjacking

Mudjacking, or slab jacking, involves pumping a cement-based mixture into and under sunken concrete, filling voids and raising the slab. While less invasive and expensive than completely replacing the concrete, mudjacking has some of the same disadvantages:

  • It often costs more than PolyLevel
  • Like concrete replacement, Mudjacking has a long curing time
  • Mudjacking adds weight around and beneath the slab, likely causing concrete re-settlement
  • Mudjacking requires drilling much larger holes than PolyLeveling, leaving ugly blemishes on concrete slabs
Polyurethane Foam Injection
PolyFoam concrete lifting

Polyurethane foam injection, also known as polyfoam injection or polyjacking, is a popular method of raising sinking concrete slabs. Similar to mudjacking in principle, polyfoam injection offers a faster installation and cure time and more attractive results. Best of all, polyfoam injection is designed to lift and level concrete slabs while filling voids in the soil to keep the slab from sinking again.

The fact that polyfoam injection not only lifts and levels concrete but also addresses the soil issues beneath it explains why it is the leading alternative to concrete replacement, mudjacking, and other more invasive approaches to concrete slab repair.

PolyLevel is a leading polyfoam concrete leveling solution that offers fast, affordable, and effective concrete slab repair. And since PolyLevel also addresses the underlying soil conditions that cause sinking concrete slabs, it offers a permanent fix for homeowners seeking lasting peace of mind.

How does PolyLevel work?

1

The concrete lifting contractor drills one or more small holes in the sunken area of the slab.

2

They inject an expanding polyurethane foam beneath the slab. As the foam expands, it fills voids and pushes the slab back towards its original position.

3

The PolyLevel contractor monitors the expanding foam, controlling the injection process for just the right degree of slab-raising action.

4

In less than an hour, with no downtime waiting for new concrete or mortar to cure, your concrete walkway, patio, or driveway is ready to use!
