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 the 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. A homeowner can fix simple foundation cracks that don’t involve drilling holes in the foundation walls or using high-pressure injection systems. Cracks that leak should be fixed by 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 to 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 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 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 if an 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 are 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.

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, lifting it back to its original level. Once this is complete, the holes can then be filled and the site can be cleaned up. Mudjacking is a 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, polyurethane foam is injected into the concrete, but through much smaller-sized and a fewer number of holes. This foam will expand an incredible amount and travel through the concrete, filling every 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. Unlike mudjacking, polyjacking is a quick process and the concrete can be used about 15 minutes 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.

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 (hydrostatic) 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. Airlift Concrete Experts cares about the quality of Arkansas homes and the safety of you and your family – which is why we offer free quotes for all of your concrete repair needs. We also offer a method that is quick and affordable and requires no demolition or disturbance to your property.
