How To Fix Foundation Cracks

Many homeowners with foundation cracks look for quick DIY solutions to get the damage repaired as quickly and easily as possible. However, quick solutions such as caulking and sealing cracks will only provide a temporary cosmetic solution if you have serious foundation damage.

Sometimes, foundation cracks indicate more than what meets the eye: an underlying structural issue. In this case, simply sealing cracks will not prevent your foundation from continuing to settle into the ground. So how do you know if your foundation cracks are serious enough for structural repair?

Do My Foundation Cracks Need Structural Repair?

Vertical and diagonal cracks in your home’s foundation are most often a sign of natural settlement and not necessarily a sign of structural damage in your home. If the crack seems even when you run your finger across it, that probably isn’t a sign of a major problem, and you should be able to do minor cosmetic repair yourself.

Horizontal cracks can be signs of a serious foundation problem.

Larger cracks that aren’t serious enough to indicate foundation failure may be repaired by you or a contractor. Even a homeowner can fix simple foundation cracks that don’t involve drilling holes into the foundation walls or using high-pressure injection systems. Cracks that leak should be fixed by an Airlift Concrete Experts because we have the tools, products and know-how to repair them.

Cracks larger than 1/4” in width, particularly horizontal cracks and ones that leak, are a different matter, and you should consult Airlift Concrete Experts to determine whether further repairs should be implemented in order avoid serious foundation problems or even foundation failure.

Foundation Crack Repair Methods

Following are various methods used by homeowners and professionals to repair foundation cracks. Some methods are more reliable and longer-lasting than others.

Caulk Crack Repair

Often homeowners may try to patch a leaking crack with caulk. This repair lasts only 6 months to a year because water will continue to fill the crack behind the patch. Eventually efflorescence, a white mineral salt in the groundwater, will break the seal and eventually allow water to seep in again.

Hydraulic Cement Crack Fillings

Sometimes homeowners or contractors will try to repair the crack by chiseling out an inverted V-groove and filling it with hydraulic cement. While the cement will fill the hole, it doesn’t bond with the cement. Usually within a couple of years, the concrete wall will fluctuate with changes in temperature and moisture and cause the plug to leak again.

Epoxy Crack Injections

Epoxy crack injection is an effective method designed to fix cracks in poured concrete foundations. Airlift Concrete Experts is highly experienced and knowledgeable about this type of repair.

This type of repair is applied from the inside of your basement, so there is no need for excavation on the outside. Once the epoxy is applied, it usually takes about 5 hours to cure. Epoxy injections will permanently seal cracks and provide structural integrity as the epoxy is stronger than the concrete itself. Call Airlift Concrete Experts today to learn more and find out of epoxy injection is the right solution for you!

Excavation

Sometimes, foundation cracks will continue to form because of serious water issues affecting the foundation. In this case, excavation is required. All structures, sidewalks, gardens and landscaping are removed during excavation. Then multiple layers of synthetic waterproof material is installed to prevent further movement of the wall and prevent water from affecting the foundation.

After the waterproofing is installed, everything is returned. It is important to keep in mind that the excavated soil will settle during the first year, so you will need to regrade it the following year.

Polyurethane Polymer Injection

The best method to repair a foundation crack that is leaking is to inject into it a high-viscosity polyurethane polymer. Unlike other fillers, polyurethane bonds well to both wet and dry concrete, and its high viscosity allows it to fill even the smallest hairline cracks.

Polyurethane polymer can be developed to expand up to 20 times its volume if needed. As a result, the seal will not fail as the wall continues to move and shift. Also, it is much less expensive than other exterior methods because it requires no labor-intensive excavation and can be completed within a few hours.

Fix Foundation Cracks with Steel Piers

Foundation Piers

For more serious cases where foundation cracks indicate structural damage, we can install steel foundation piers to bring permanent stability to your home, preventing cracks and other issues from forming in the future. Steel piers are drilled below the weak, top layers of the soil until they reach more stable soil deeper in the ground. The weight of your home is then lifted onto the piers, permanently stabilized. Cracks can now be sealed without worry of forming again because the foundation is in place for good.

Polyjacking vs. Mudjacking

If you have concrete on your property that is sunken, uneven, or full of voids and spaces, you may be wondering what the best solution is. Sometimes, damaged concrete appears like it should be completely replaced, but there are several repair options that can make your concrete as good as new. Polyjacking and mudjacking are both popular and effective methods for repairing your concrete, but which one should you choose? Here we will look at both solutions and help to steer you in the right direction.

Mudjacking

Mudjacking is a process in which holes are drilled into the affected area of your concrete, and filled with a mixture of cement, water, and grout. This mixture, called slurry, will fill the voids beneath your concrete and through hydraulic pressure, lift it back to it’s original level. Once this is complete, the holes can then be filled and the site can be cleaned up. Mudjacking is a quick and cost effective process, and can be applied to a variety of areas such as driveways, sidewalks, porch steps, and more. Although the slurry mixture gives strength to the concrete, it is also extremely heavy, adding weight to the sub base.

Polyjacking

Like mudjacking, polyjacking also requires drilled holes and injections. This time, a polyurethane foam is injected into the concrete. This foam will expand an incredible amount and travel through the concrete, filling every small or large void that is present. It can accurately lift your concrete even to 10/1000th of an inch! The polyurethane foam is much more lightweight than the slurry that is used in mudjacking, which may not provide as much tensile strength, but it allows for the soil around it to be compacted. This prevents future foundation failure and keeps concrete stable for years to come. Like mudjacking, polyjacking is a quick process and the concrete can be used almost immediately after it is fixed. Polyjacking can also be applied to various places including your garage floor, walkways, patio, and more.

Here at Airlift Concrete Experts, we recommend polyjacking for all concrete raising, leveling, and stabilization applications. Polyjacking is a quick, cost-effective, and efficient method that has proven to last for years to come. To learn more about the benefits of polyjacking, click here.

Types of Foundation Cracks and How to Fix Them

Diagnosing Cracks in Your Foundation

Cracks in your foundation come in a wide variety of shapes and sizes. It is not unusual for foundation cracks to form within the first year of new construction, often near windows, corners of the walls or floors or in the longer sections of your foundation. Most are due to foundation settling and are usually not a cause for concern. If cracks become larger or allow water to seep through, call an expert right away before the damage becomes worse.

Is My Foundation Crack Normal or Dangerous?

If you are unsure about your foundation cracks, monitor them to see if they are increasing in size. Simply use a pencil to mark off and date the ends of each crack. Within a period of time you will be able to tell if the crack is due to natural settling or if it indicates a more serious problem. Tracking them will also help foundation repair experts determine how they were formed and the best way to fix them. Take a look at the types of foundation cracks below to determine if your foundation crack is a cause for concern.

Vertical and Diagonal Foundation Cracks

Usually a diagonal or vertical crack in the foundation wall is the result of settling in the concrete foundation and is quite common in new construction. Because concrete shrinks while it cures, these cracks are called shrinkage cracks. They usually run vertically or diagonally, are often located in middle section of walls and are less than 1/8 in wide.

Frequently you will find vertical cracks in block foundations. If the crack is located closer to a corner andis wider than 1/8 in, it is probably not due to shrinkage but indicates a more serious foundation issue. If your vertical foundation crack is wider than 1/8 of an inch, call a professional to get it inspected as it may be a cause for concern.

Horizontal Foundation Cracks

They are caused by hydrostatic (water) pressure from the outside of the walls and can lead to a failure in the foundation. Most foundations are designed to handle the pressure of water and soil.  Additional pressure due to heavy rains or flooding can create serious horizontal cracks that need to be repaired as soon as possible.

When is a Foundation Beyond Repair?

structural cracks in houses, serious foundation crack, crack in brick foundatioinFortunately, most foundation issues can be repaired with underpinning solutions and hydraulic lifting. A foundation may be considered beyond repair if the investment that it takes to restore it does not add enough value to the home. Although very uncommon, this sometimes occurs when a foundation has completely collapsed and the damage to the home is detrimental.

Listed below are some of the most serious foundation problems that we have seen that should be addressed immediately before your foundation collapses and fails:

  • Cracks that change direction
  • Bulging walls due to water pressure
  • Sloping and weak floors above the foundation
  • Vertical foundation cracks wider at the top than the bottom
  • Fitting a dime through a foundation crack

If you have any of these signs in your Arkansas home, contact a professional contractor as soon as possible. If walls are bulging after a recent flooding, your foundation may be in danger of an imminent collapse. Contact Airlift Concrete Experts immediately.

Repairing Vertical or Diagonal Cracks

Vertical and diagonal cracks in your home’s foundation are most often a sign of foundation settlement and not necessarily a sign of structural damage in your home. If the crack seems even when you run your finger across it, it probably isn’t a sign of a major problem.

Sometimes homeowners and contractors will try to repair the crack by chiseling out an inverted V-groove into and filling it with hydraulic cement. While the new cement will fill the hole, it doesn’t bond with the original cement. Usually within a couple of years, the concrete wall will fluctuate with changes in temperature and moisture and cause the plug to leak again.

Airlift Concrete Experts has professional solutions to fix your vertical foundation cracks once and for all. If you have small cracks and/or water seepage, we can use epoxy injections to repair a diagonal or vertical crack. Once a crack is large enough to insert a dime, you may have a foundation problem and you will need to invest in structural repair.

Repairing Horizontal Cracks

Horizontal cracks on foundation walls often indicate serious problems that may eventually lead to complete foundation wall failure. If the soil around your home is not properly graded and drained, water will eventually saturate the ground around the foundation walls and increase the hydrostatic (water) pressure which may exceed the weight-bearing capacity of the walls and cause them to crack or bow. Homes with clay soils that expand and contract significantly are particularly vulnerable to lateral pressure on their walls.

One of the best methods used for crack repair is epoxy injections.  Epoxy injection is a system that welds cracks back together.  It restores the original strength and loading of the original concrete.  Epoxy injections also restore the design and structural quality and make the concrete seem as good as new.  The epoxy seal makes the foundation impervious seal to air, water, chemicals, debris, and other contaminants.

Go Crack-Free Forever With Professional Foundation Repair

Sometimes filling horizontal cracks and repairing other cosmetic problems simply isn’t enough.  They won’t solve the underlying issues of a failing foundation.  So what should you do?  If you want to benefit from long-lasting results, contact the team at Airlift Concrete Experts. We have the foundation repair solutions that you need to keep your home strong, stable, and crack-free for years to come.

The Best Crawl Space Repair Solutions

Most homeowners in Arkansas rarely think about their crawl space. After all, it’s not a place that you spend a lot of time in! However, your crawl space is more important than you may realize.

Did you know that 40-50% of the air that you breathe inside of your home originates from your crawl space? Considering this, it’s important to keep your crawl space clean and healthy. If you have a wet, damp, or musty crawl space, it can promote mold growth and cause a health hazard for you and your family. Wet crawl spaces also lead to structural failure, which can lead to serious issues and costly repairs.

How can you know if your crawl space needs repair? Look for the following signs:

  • crawl space repair little rock arMusty, strange odors
  • Sagging floors
  • Sloping or uneven floors
  • Squeaking and buckling floors
  • High moisture levels
  • Indoor humidity and condensation
  • Standing water in or around your home

Chipping Concrete Repair with Polyjacking

Do you have cracked or sunken concrete on your property? Like many Arkansas homeowners, you may have noticed chipping concrete on your porch steps, or a sloping driveway or walkway. Concrete problems like these are not uncommon, especially on Arkansas soils.

What Causes Concrete Damage?

One of the main causes of concrete chipping or cracking is soil expansion. When the soil beneath your home becomes heavily saturated with water (due to weather, drainage leaks, or excessive watering), it will create hydraulic pressure against your concrete. When the pressure is great enough, your concrete will chip, crack, settle, or heave.

You may be ignoring concrete repair because it seems like a large (and expensive) undertaking. However, damaged concrete is unsightly, lowers the value of your home, and presents a tripping hazard to you and to guests.
