Concrete cracks can be caused by various factors such as repeated freezing and thawing, heavy loads, tree roots, and ground shifts. To repair cracks in concrete slabs, homeowners can apply a caulk gun and smooth it down with a putty knife. Epoxy filler provides a strong and durable repair solution, and crack sealing is a common method.
To repair narrow concrete cracks, cut a groove on both sides of the cracked concrete using a diamond blade on a circular saw. This will prevent bigger, more severe cracks from forming. Common concrete slab repair methods include surface filling or injecting with epoxy or polyurethane, filling and bonding the slab back together, and polyurethane foam concrete lifting.
To remove damaged or crumbling concrete, use a small sledgehammer and chisel to undercut the edges of the damaged area. A professional drills a hole in the sunken portions of the slab and pumps a cementitious material underneath. Make sure your slab is clean and free of loose concrete, and use a pressure washer to get it ready for resurfacing.
Patching with grout or mortar is a common way to address cracks, but it’s typically a temporary solution. Caulking epoxy or polyurea is another effective method for repairing cracks in concrete. In most cases, all concrete cracks are worth repairing for aesthetic reasons, longevity, and prevention of larger, more severe issues.

Can concrete slabs be repaired?
Cracked concrete slabs can be repaired by analyzing the crack, diagnosing the cause, sealing smaller cracks with polyurethane to prevent water seepage, applying epoxy resin to larger cracks for a more structurally sound seal, wrapping the slab with reinforcement materials like synthetic fabrics and carbon fiber to increase load capacity, and applying protective boards or equipment if necessary. Safety is always the top priority when it comes to concrete cracks, and sealants and resins should be used to close these cracks.
However, it is crucial to seek an expert assessment from a concrete slab repair company if the structural integrity of the slab is compromised. For more information on fixing broken slabs and sealing cracks in concrete, visit resource pages for further guidance.
Can I pour concrete over damaged concrete?
In the event that a concrete structure exhibits indications of deterioration, it is advisable to either remove or repair the structure. The addition of a new layer of concrete will not address the underlying structural issues, which will inevitably manifest themselves in the upper layer. Concrete overlays can be employed to augment the elevation of a concrete structure, such as extending a wall or elevating a walkway to align with a patio.
Is a house on a concrete slab good?
Building a house on a concrete slab foundation offers numerous advantages, including quick drying, strength, durability, protection against insects, and the ability to hold heavy furniture. Choosing a slab foundation over a crawl space foundation reduces flooding risk by directing rainwater away and reducing condensation. Additionally, mold and mildew infestations are less likely due to the lack of moisture in the basement or crawlspace. Slab foundations typically cost between $10, 000 and $20, 000, with a concreate slab often being half the cost of a basement or crawl space.
How to fix a badly poured concrete slab?
Three ways to fix poorly finished concrete are patching, resurfacing, and staining. Patching involves applying a new layer of concrete over an old one, which can be textured or smooth. This is ideal for small damaged or cracked areas. Resurfacing is a more extensive method that involves grinding down the old surface and applying a new one, best for large areas in bad condition. It is more expensive but yields a higher quality finished product. Staining is a great option for changing the color of concrete without resurfacing it. It involves applying a colored sealer to the surface, is less expensive, and can be done in one day.
Can concrete floors be repaired?
To prepare a concrete floor for a new finish, follow these steps:
Inspect the floor for cracks and chips. Use a concrete repair compound for small fissures, or a concrete patching material for larger ones. Apply the product according to the instructions, smooth the surface, and allow ample drying time.
Use a floor grinder with diamond tools to prepare the concrete by smoothing it out, removing old coatings, and opening up pores. This step is crucial for new finishes and ensures uniformity.
Fine-tune the floor with fine-grit sandpaper or resin diamonds to create a smooth, ready-to-finish surface. This step is especially important for applying paint or water-based sealant, as it helps the new material adhere better and last longer.
What is the disadvantage of a concrete house?
Concrete homes are a popular construction method due to their unique skill set and the limited resources available. Many companies lack the necessary resources to construct them, which can be a challenge in rural areas. Additionally, the construction process requires workers with specific skills, leading to increased costs. These costs include labor, material, transportation, and market competition.
Consequently, concrete homes are generally more expensive than traditional homes due to these factors. Therefore, it is essential to carefully consider the location and resources when considering concrete home construction.
How to fix a concrete slab house?
Slabjacking is a method of concrete lifting used to restore a cracked slab to its original position. It involves drilling holes through the slab and injecting filler material underneath it. The filler material takes up space under the slab and raises it to the desired height. The terms concrete lifting, concrete leveling, slabjacking, and mudjacking are often confused, but this article explains their differences and their meanings. It’s a crucial step in repairing interior cracked slabs.
Can I repair concrete myself?
Concrete can be repaired with most products, starting with a clean, debris-free surface. A wire brush is a good tool for preparing concrete for fixing. Horizontal cracks in concrete outside your home can be concerning, as they are often caused by external factors or foundation shifts. Addressing these cracks right away is crucial as they can grow over time, cause more damage, and allow water to leak in, making the repair more expensive.
Can you put a thin layer of concrete over concrete?
Pouring concrete over concrete requires a minimum thickness of 2 inches to prevent cracking and bonding issues. SUNDEK of Austin applied a SunStamp coating to a residential pool area in Jonestown, TX, for a durable, non-slip surface. However, pouring concrete over concrete is not always the best way to update or fix your concrete slab. Other options include using a different type of concrete or a different coating.
Will new concrete stick to old concrete?
The minimum thickness of a concrete overlay depends on factors like the application method and aggregate size. Adding concrete over an existing slab adds 25 to 100 millimeters. Concrete is composed of sand and aggregates, and it cannot bond naturally to the existing slab due to its lack of natural bonding agents. A bonding agent or unbonded overlay method is needed to adhere the layers together. Properly installed concrete can last over 50 years, but the existing concrete’s condition affects the new overlay’s life span. To pour concrete over concrete, assess the existing slab for structural stability and check for tree roots, cracks or buckling due to frost heaves, and signs of settling.

Great simple overview with cost estimate. Some other companies go crazy when asked about how much. Finally got a quote that came in at $88k to fix a 1″-4″ slants of a 3 story house built in 1996 in Washington state. 26 of 29 helical piles will be installed inside foundation basement and 30 feet of C6x8.2 steel website and poly-foam fill. Approx 44×30. Seems like the middle of the house is good and the north and south of house slant down. Is it possible to get a ground compaction test and see if I can save money and have a foundation company with engineering jack it up to level and add more foundation ?
I did exactly that (with the painter’s tape and brush) to creat a small ramp between my walkway and driveway. The height difference was about 3\\4″. It has gone through 3 Canadians winters now. The feathered edge (and the rest of the ramp) still look like the day I finished it. I LOVE this stuff! I just wish there was asphalt repair that would hold as well as this one.
Should you allow some time for the filled-in crack to harden and dry before putting on the top coat? Also according to the Top’n Bond instructions, it’s not supposed to be more than 1/2″ in thickness on each application, and it seems it is more like 1″ thick at the high end in your demo. In that case, should there be 2 separate applications?
I followed you here (thanks!) and this is what I’ve been looking for since March ’23. Sidewalk isn’t cracked, a root pushes the slap from about 2″ high down to an even point. I’ll use Top N Bond but I’m confused about the “SSD”. Painters’ tape is pretty common to see around here, so I’m convinced it’ll work. But then do I need to use another product? I get that the cement needs to adhere to the sidewalk. I can handle hydraulic cement but this is new for me.
I just bought some Top N Bond to use to skim coat my basement walls to fill surface imperfections left by an incompetent contractor. There are two things that the bag of Top N Bond instructs me to do but I don’t see on this article: 1.) priming the surface with a slurry of Top N Bond. 2.) keeping the surface moist while it cures for 24 hours. I would prefer to not have to include these steps. Are they necessary?
