Benefits of Concrete Lifting

Besides preventing future damages, concrete lifting provides many added benefits that make it a worthwhile repair option. Here’s a few other reasons homeowners might consider a concrete lifting solution.

Increased Safety

If you’ve been dealing with cracked or uneven concrete, it runs a serious risk to safety for anyone visiting or living in your Denver, Boulder, Colorado Springs or Grand Junction home. Not to mention, regularly driving over uneven concrete can take a serious toll on your vehicle’s longevity. Concrete lifting can save you a trip to the repair shop and keep those you love safe from injury.


Maybe you’ve tried alternative forms of concrete lifting such as mudjacking. Unfortunately, this method rarely works, as the dried mud ends up experiencing the same symptoms as the original soil. Plus, the process takes a long time and tends to be messy. PolyRenewal™ avoids all of these issues and keeps your concrete functional for years!

Curb Appeal

Trying to sell your home? Uneven concrete can vastly decrease a home’s curb appeal and make it harder to sell. Even if you aren’t trying to move, damaged concrete can be a major eyesore in general. Concrete lifting can give your home a much-needed renewal.


When you’re looking into raising concrete, there are going to be a few different options for concrete raising, and polyurethane foam injections are going to be one of the best ways for you to raise the concrete. That’s because it’s a mix of different elements that, when combined, expand to substantially more than their initial mass, then harden very quickly.

At their core, polyurethane foam injections work well because they don’t need a lot of time to set but they’ll still maintain a lot of weight. You don’t have to worry about whether they’re “as effective” as more invasive options like slabjacking or mudjacking. They’re at least this effective, and in many cases, they’re more effective.

The freeze-thaw effect describes the cycle water goes through as it turns into ice and then melts back into its liquid form. The freeze-thaw effect is part of the reason why it’s so important to protect your concrete from moisture exposure if you want to prevent structural damage. When water turns into ice, it expands by about 9%. It may not seem like it, but expanding ice is fully capable of displacing concrete particles. Every time there’s some sort of displacement, the concrete becomes structurally weaker with time.

The freeze-thaw cycle is capable of creating small craters both inside and along the surface of the concrete. Concrete is already impermeable, but with each new micro-tear, it allows moisture to seep through even more. As more and more water gets past the structure, the freeze-thaw cycle also displaces the soil underneath. Concrete settling advances, and then you have an uneven, structurally weak slab. The more porous concrete is, the worse its tensile strength is, so cracking is inevitable on a slab that has been exposed to moisture during the winter.

How dangerous exposure to the freeze-thaw cycle is depends on the severity of the winter climate. Freeze-thaw is a lot more impactful on concrete with low psi, which is typically the case for slabs made for walkways, since they aren’t considered to be “heavy duty” slabs. Keeping the snow off of your concrete is an integral part of slab protection, so consider covering your concrete during the winter. This way, if your slab does settle, you can avoid having to replace it due to breakage that prevents repairs.

Uneven concrete slabs are pretty dangerous on their own, but things get even riskier if it’s an uneven pool deck. The settling that occurs around pool decks are more likely to cause accidents because of the water, and those that don’t know how to swim run the risk of falling into the pool. 

But what exactly causes uneven pool decks? Is it the same thing that causes concrete settling in your driveway or garage? Well, sort of, but there’s a bit of a twist to it that involves the pool’s construction. A pool is made by digging a hole large enough to fill a pool. Once all the walls are put into place, soil is backfilled around the excavated area until there’s no sign of the hole. The problem with this is that while the soil surrounding the pool is compacted, dense, and capable of holding up the pool, the soil that’s used as backfill is very loose. Because of the soil’s looseness, when the concrete slabs are poured over the soil, it compresses together, forming a gap under the concrete that causes settling. There’s very little that can be done about this during the construction of the pool itself, so all you can do as a homeowner is repair the settled slabs.

Different types of soil have different load-bearing capacities. When a soil’s load-bearing capacity is exceeded, the soil will compact and settle. It’s also possible for the soil beneath a slab to settle and compact of its own accord. Soil that contains large amounts of clay and/or silt will shrink substantially when it gets dry. As the soil compacts underneath a concrete slab, the unsupported slab will sink as well, usually cracking in one or more spots.

The soil that is underneath your driveway, patio, or concrete steps may not necessarily remain there to provide adequate support for the concrete element. As water moves underneath your concrete slabs, it can wash away the soil that’s supporting the weight of the concrete. As this happens, it creates a void, or empty space, underneath. Over time, with nothing to support it, your concrete slab can begin to sink or cave in.

Concrete slabs crack due to problems with the soil beneath them. All soil inevitably erodes over time or gets washed out by water and rainfall. As it does, voids are formed below the concrete slab part of your Colorado home’s foundation and there’s nothing more to support its weight. When that happens, the concrete starts to sink and break at pressure points.

In order to lift the concrete, you should also fix the holes beneath it that have caused it to sink in the first place. That can’t be done with outdated methods for concrete lifting such as mudjacking. New methods that use polyurethane foam fix both the concrete and the soil issue by filling in the holes and providing a long-term solution to this issue.

Sometimes, the cause for the cracking is in the concrete itself and that’s what happens when the concrete isn’t sturdy enough. There’s no solution for this problem other than removing the concrete slab altogether and installing a new one out of reliable concrete that will provide better material.

For decades, civil engineers have been trying to perfect the concrete lifting process by mixing different materials with cement and pumping that mixture under the slab. Even though these various mixtures have different advantages and disadvantages, the result is always the same: A short-term solution for a sinking slab that can sometimes make the situation worse. Luckily, we live in a time where we have the tools and the materials capable of providing homeowners with a long-term solution. That solution would be PolyRenewal™, our polyurethane foam injection procedure that permanently repairs sinking slabs. It’s a contemporary concrete lifting method that doesn’t disappoint, not only because of the results, but also because of its convenience.

What makes PolyRenewal™ so great is that it doesn’t have any of the downsides that makes mudjacking such a problematic method. The cement slurry in mudjacking eventually erodes with time as the particles get displaced due to water and expanding ice. The crack formed from this displacement makes it so that water permeates past the concrete and reaches the soil, which causes settling down the line. The polyurethane foam we use is impermeable, meaning that it doesn’t erode nor does it allow moisture to seep through and saturate the soil. The same amount of polyurethane foam that is injected under the slab will stay there for decades.

Polyurethane foam is also lightweight. Cement is rough and heavy, so a mudjacking job does nothing but displace the soil further. Closed-cell polyurethane foam is dense enough to support heavy loads without disrupting the soil underneath. All in all, PolyRenewal™ is the superior concrete lifting option because it does what soil and cement cannot do: Provide the slab with a foundation that will not shift or wash away.

Helpful Concrete Lifting Tips

  • Keep an Eye on Your Foundation – Closely monitoring your foundation and concrete structures is the best thing any homeowner can do when it comes to concrete lifting. This can help you stay on top of concrete damage and act quickly before issues become worse.
