The Big Questions

How long does concrete leveling take?

Concrete leveling usually takes less than one day, depending on the scope of the project. Your concrete is ready to be used the moment we leave your home.

What are the benefits of concrete lifting?

Polyurethane injections require smaller and fewer holes, and the hole repairs are virtually unnoticeable. Once the polyurethane cures, it won’t be compromised by water or chemicals in soil, which means your concrete will avoid moisture intrusion and potential re-settlement for years to come.

Will it damage my landscaping?

Liftech’s heavy equipment stays on the street and we use lightweight hoses for the polyurethane injections themselves, so you don’t have to worry about your landscape getting disturbed or damaged in any way.  Our process is virtually mess-free!

How long before I can use my concrete?

Our polyurethane is fully cured in 15 minutes.  By the time we clean up and leave the job, you can use your concrete immediately!  You can even park your cars on your newly repaired concrete.

Will my concrete move after the fact?

Continued settlement of the soil under your concrete and under our polyurethane is always a possibility, especially when dealing with exterior concrete. Colorado soils have a very high density of clay which is porous and prone to expansion and shrinkage when introduced to water.  Just as the earth moves, so does your concrete.  You may notice minor seasonal shifting in your concrete up and down as the soil “breathes” but this is nothing to worry about — that’s the way nature works.  Our experts will also work with you to identify and correct grading and drainage issues around your home to prevent recurring issues with your concrete settling.

How do I choose the right concrete lifting company?

Make sure you choose a company that’s fully licensed and insured in your area. Only interview companies that specialize in lifting, leveling, and stabilization of concrete structures and that have a long and successful track record of making such repairs. Make sure the company you use is utilizing the most current and advanced material and techniques for the job.  Finally, research all of the impartial review sites that advocate for consumers to find the most accurate and thorough concrete lifting company reviews on the Internet.  These include Google, Yelp!, Angie’s List, Home Advisor, the Better Business Bureau, NextDoor and others.

The Cost of Concrete Lifting and Leveling

Concrete lifting and leveling might seem daunting and expensive at first glance, whether you’re hoping to fix your driveway, basement floor, garage, patio, or sidewalk. But the cost of ignoring your concrete problems or replacing your concrete altogether are likely much worse. Let’s take a look at the difference between repairing and replacing your concrete:

Replacing a driveway, for example, can cost thousands of dollars — and you’ll have to deal 1-2 weeks of concrete removal, jackhammer noise, construction crews, and concrete trucks parked on your street.  And even after that new concrete is poured, THERE IS NO GUARANTEE IT WON’T SETTLE AGAIN!

The same goes with basement floors. Floor replacements not only tear up your finished basement creating a huge mess for you, but will also likely cost you tens of thousands dollars and weeks of downtime.  And don’t forget about all of those construction workers tracking in and out of your house!

With Liftech, your concrete will be stabilized, lifted, and leveled at a fraction of the cost of a replacement USUALLY WITHIN 1 DAY!  Our technicians will use polyurethane injections about the size of a penny to restore your concrete to the original height. It’s minimally invasive  and we won’t disturb landscaping or tear up your finished basement to get the job done.  It’s cost-effective, and you can enjoy the results of our work the moment we leave your property. Repairing your shifting or damaged concrete is easy — it all starts with a free onsite estimate!

Why is my concrete shifting and settling?

There are a few primary reasons why basement floors, garage floors, driveways, porches/patios, and walkways are prone to shifting, settling, sagging, and cracking. Let’s take a look at how water, soil, and vegetation can play a part in concrete movement and damage:

Cause #1: Poor Compaction

The building envelope where your home sits is often full of loose soil and fill from when the home was originally constructed.  The vast majority of homes in Colorado’s Front Range have basements, which means large holes are dug and the area around the foundation over-excavated to allow for the forming of the foundation walls.  This area is then “back-filled” after the foundation walls are poured and the loose fill has a tendency to settle back in over time.  Concrete structures on either side of the foundation that sit in this “compaction zone” ultimately sink and settle as the underlying soil settles back in.

Cause #2: Water

Water has a compacting effect on soil.  Poor drainage around your home, combined with rain and snow melt, will evacuate the open air pockets and pores in the loose soil beneath your concrete.  As the moisture dries out, voids will form in the soil and it often collapses upon itself taking the overlying concrete with it.  The result is your concrete settling, sinking, and cracking.  Flooding events such as a pipe leak or burst under the concrete may also cause the same issues.

Cause #3: Inadequate Drainage

If water is constantly being driven under the concrete, IT WILL EVENTUALLY FAIL!  Many homeowners ignore the grading around their home and allow water to flow towards the foundation and the concrete structures around it, instead of away from it.  This combined with leaky gutters, downspouts without extensions, extensive watering of vegetation close to the concrete and other homeowner mistakes will ultimately cause the soil and overlying concrete to sink and settle.

A Word About Bentonite

A common misnomer is that Bentonite causes concrete to settle.  IT DOES NOT!  Bentonite is an expansive clay found in soil across Wyoming and Colorado that’s composed of a variety of elements. Most forms of bentonite EXPAND when exposed to moisture — it can absorb several times its dry mass through groundwater, rainwater, and snowmelt. While bentonite certainly has its uses in lining landfills and in oil drilling, the fact that bentonite is present in soil across the state of Colorado can be problematic for contractors and homeowners alike.

 Bentonite causes upheaval under the concrete, not settling, and over time it can put pressure on home foundations and concrete structures.  This can lead to foundation damage and heaving or uplifting of concrete flatwork.  In most cases, when concrete flatwork is heaved, the only option is to replace it.  Though foundations can still be repaired when they have experienced damage due to expansive soils.


Signs Your Home Needs Concrete Leveling

Once poor compaction, inadequate drainage and water infiltration take a toll on your interior and exterior concrete, your concrete is no longer properly supported. Over time, this will cause cosmetic damage, additional moisture intrusion, foundation issues, cracking and other potentially costly and hazardous issues in and around your home. Let’s take a look at the signs your home might need concrete leveling so you can take action to repair your concrete before its too late.

There are gaps between the baseboards and your floor.

If you notice a gap between your baseboard molding and your floor, there’s a very good chance your floor is sinking. Polyurethane injections will lift your floor back up where it should be.

You have water pooling in your garage.

Properly constructed garage floors are built to move water away from the foundation towards the entrance to the garage.  If water pools in your garage when you drive your vehicle into it after a rain or snow storm, it is likely a sign that the floor is sinking and the drainage has been compromised. Polyurethane injections will correct the grade on your garage floor so water will drain out of it, instead of into the garage.

Your porch or patio is “pulling away” from your home.

If you notice your concrete patio or porch starting to tilt away from your home, there’s a very good chance the underlying soil is causing movement and damage. By taking advantage of our concrete lifting services, your porch will not only be restored to its original condition, but it will be more stable with a solid bed of polyurethane underneath it!

Your concrete is cracking and uneven.

There are two types of concrete here in Colorado – new concrete and cracked concrete.  While it is completely normal and expected for ANY concrete to have cracks in it, excessive cracking that continues to widen and grow is usually a sign that the soils are unstable under the concrete.  If your concrete is being pushed up from tree roots or from expanding Bentonite, there is a good chance it will need to be replaced.  But if the concrete is moving downward and settling, there is an even better chance Liftech’s polyurethane injection techniques will restore it back to its original condition quickly and at a fraction of the cost of replacement.
