Thanks for stopping by Concrete Repairman. What you are viewing is a floor heave fracture on an interior floor in a bedroom. And this is a keyway joint, right here running that direction and this is a separate crack, so we consider this as a triangulated fracture. Triangulated fractures means that, there's an elevation here, and elevation there and an elevation there, three elevations on the exterior floor. There are vertical breaks on this side of the this home, and also over here next to the patio area in this master bedroom. When the foundation wall goes down, based on the evidence of the vertical fractures on this side of the home, because of the rain water saturation near the foundation. This means that the foundation wall is going down and broke. This floor is poured independently and is non monolithic but, it does have outward pressures north south east and west, and will follow the foundation wall down with it causing these floor heaves. It's not necessarily the case of “expansive soil” pushing up, causing these floor heaves. All you have to do simply at home, a technique that's widely used is, just take a hammer and start tapping near these cracks, and see if you hear a hollow sound. A hollow sound means, that it's lifting and doing exactly what I just said the foundation walls going down. If it were “expansive soil,” if your home moves enough, then it will break water lines and cause interior water underneath your floor slab. Just simply take a hammer tap on the crack, sounds hollow? It's not likely expansive soil, pretty simple. When this foundation goes down, it's also going to cause, in the ceiling, and there's a lot stress here in this roof structure. If this continues, it will rip the roof wide open! Before this gets to that type of structural damage, you definitely need six inch aluminum seamless rain gutters with four-foot downspout extensions all the way around these homes here in Arizona. This wall is an exterior perimeter wall sitting on top of perimeter footing, and this is an interior wall sitting on top of an interior floor. Where the interior wall, and the perimeter wall meet, you get “shearing,” separation. That means that the outside wall is moving down.

Please comment if you have any questions. Thank you. Poor soil conditions in the excavated area cause compaction and can make it difficult to dig out foundation depths that are deeper than the top of the soil. Subsoil cracks are formed when the base of the foundation is deeper than the top of the soil. The loose soil and compacted soil meet at the foundation and will cause foundation heave. A foundation inspection is required before any excavation begins to prevent heaving and cracks in the future. In order to prevent or reduce the likelihood of foundation heave, every owner should take steps to improve soil conditions. Before digging, owners should remove soil from the excavation. This will help decrease the likelihood of foundation heave. Additionally, it is important to use good quality clay soil mix when excavating. Clay soils are stronger and require less compaction. By using high quality soils, the property owner ensures a sound foundation. After removing the old soil, good quality clay soils will be necessary for foundation repair. This should be done before excavating is begun. It is best to consult with a qualified foundation specialist to determine the best clay soils to use. Quality soil will need to be added to the foundation excavation site, after soil has been removed and for the remainder of the excavation process. Foundation engineers recommend adding a 10 percent grade to provide extra support to the new foundation structure. To help add to the strength of the soil, the grade should be evenly distributed throughout the site. Using the appropriate soil will also allow the new foundation to drain properly. If proper drainage is not provided, foundation heave will likely occur. Too much expansion or contraction of the foundation can result in foundation heave.

Thank you for this video, James! I feel very badly for these people, I hope their home was saved. I do feel reassured that my crack in the foundation that goes through two bedrooms and a bathroom, is not the same situation. I think it may have been caused by an earthquake in 1989. But we just discovered it yesterday when new carpeting was installed.

[@starynwagner]

I have watched a few of your videos and appreciate the clear explanations that you offer for the problems. I just wish I could find someone like you in Austin.

[@ConcreteRepairman]

What do you need in Austin? Foundation inspections?

[@vgm3067]

Who did you end up using in Austin? My 20* 20 tile floors are developing long hairline cracks inside the house in several places and I called the foundation companies who didn’t say much. And today I noticed that the crack is actually running from the exact same spot from the garage concrete and is exactly lining up the crack in the middle of the house running from garage to laundry and now to living room and horizontally to the kitchen. This was the first crack that was there when I bought the house since nothing was said in inspection and now it has spread. House had no rain gutters and 12 years old. I have installed the gutters but I can see changing the floors won’t help if the underlying issue is not resolved.

[@Z-Ack]

Expansive soil also contracts kind sir. This creates hollow voids under slab.. ive been living in a home on clay soil and expansive is not the correct term for it. Breathing clay soil is more like it. On say after a week of good steady rain, although i have correct grade and new gutters along with a perimeter interior drain tile with sump directed well away, my walls and lally supports on the single beam 2 story slab basement block foundation will move as much as 1-3/4” and when it dries out the column and walls, depending on saturation levels determines what moves, will lower the same. My gas pipes and water i have put on flexible piping and the meters are in balance. Only crap i get is all the inside walls upstairs, none in basement, will separate from the ceiling as well as floors will separate from baseboards equaling the moved distance of the stuff downstairs.. my slab has been repoured with rebar and installed both helical and straight piers all driven to their max pressures, filled the block with rebar and morter, put up I beams in slab every 4 feet with 4 tons of pressure against the walls, repoured all footers 48x48x48 for the 3 lally columns in my 1000 sq ft basement below grade halfway.. and now the entire house acts like a ship.. slab still cracks though and im guessing hollow voids under from movement.. every house on the block has gone through same stuff.. water mains, sewage, hell one blew up down the road and leveled it from gas leak.. is when i fixed mine.. the whole street got hush money though, dont tell anybody.. haha.. anywho im stumped as to use foam or concrete at risk of the concrete drying and having boulders shoved through the floor or the foam just collapsing and molding or something.. dunno if it does that or not.. about give up on this house after paying 120 for it and putting the same in it, feel pretty much like what im guessing a gay man does at this point.. nasty.. sorry bout that but bent over backwards just didnt push the feeling right.. anywho Food for thought.. the house thing, not the nasty.. well yea.. ok then..

[@ConcreteRepairman]

Hi Z Ack, thank you, good to here from you. Yes, expansive soils can cause problems fur shure. I have removed 100's of slab that have heaved. Only 1 slab heave was caused by the home settling causing the water line too break. This cause the esastibation of the expansive soil to swell. All others have been proven not caused by expansive soil based on the evidence on the exterior vertical breaks, cracks in walls, doors not to close, and ceiling cracks. It is true that expansive soil will shrink and is usually the excuse given after you tape the crack and it sound hollow. 99% of the homes I investigate with heave cracking on interior floors is not caused by expansive soil problems. Arizona footing are 24" in depth from the interior floor elevation to the bottom of soil that holds the load. These shallow footings are easily moved by moisture holding causing settlement. These interior floors have outward pressers, and is considered a "Floating Floor". As the foundation moves downward the interior floor can follow the foundation walls down causing the interior floor heave cracks, cracks in ceilings, doors not to close ect..... The floor can also slip, and not follow the foundation wall down. Thank you for your comment. James Belville.

I just bought a house last year and now discovered that my master bedroom has this same issue and I’m freaking out because I don’t know what to do or don’t know if I should contact my insurance company

[@youngpension5093]

What ever happen bro

[@pinggong3617]

If you compact the sub-base and sub-grade correctly, add enough rebars, and no abuse afterward, then concrete slab will not crack for at least 3 decades. If any surface cracks show up just weeks or months after construction, then it suggests your contractor must did some steps incorrectly. A lot of builders use the concept of concrete will crack to mislead clients. Actually, the only reason of cracks show up in new house is because your builder slacked off and skipped away from some important sub-base and sub-grade preparation steps. if builder do each step correctly, concrete slab can maintain no-cracking for at least 30 years.

[@genecarden780]

Thank you for this video it is very rare for soil rising to cause cracking the soil is much less dense than concrete so water will take path of least resistance and that is out through the soil. Without freezing it is very difficult for water to raise a concrete slab

[@heathwatson4070]

I have this happening in a cabin I bought that was built in 1930, im looking for a more diy route of repairing this type of crack. We plan on filling the crack with cement all and floating out then grinding everything down level.

[@caziehackett492]

Hi thank you for video as im in uk and have this same problem but not beeb taken seriously and is getting worse. Crack are small now but every night they are growing, its not my property so i can not do anything

[@xr500t]

I think I have the expansive soil. The cracking seems to have been caused by heaving when the house was first built 12 years ago and no further heaving seems to be occuring. Is there a solution for that? I would like to level the floor again and relieve the tension if thats another factor in the cracking.

[@mts7274]

What if the floor drops near the walls, but the walls stay in the same place/height?

[@delt19]

Ok so how did you repair all that damage?

My basement is like that. Has water coming out of the crack in the middle of the floor. There was a water ditch built behind the house a few years ago. The house is from the 1860s. I just bought the house. Ruff ball park estimate?

[@chriswatts2096]

Here in Vegas my mother’s house has terrible cracks I feel under her carpet and some walls show exactly what you discussed in this video. I’ll subscribe and search your videos for ways to help fix it if possible.

How does something like this get repaired when it’s inside a bedroom like in this case

[@psfgtech]

On a second floor, is it ok,? I tried to paint it and still it's there, this is my condo, im worried

[@Highlos]

Thank you very informative

Your videos are great. I only hope your company was located in South Florida. I'm wondering if there is a colleague that provides the same service located in South Florida area that you could recommend

[@ConcreteRepairman]

Sorry I do not have a referral for you in South Florida.

[@altair6292]

what I would like to know is how expansive soil heave can occur quickly, randomly, and many years after a house is built, no cracks, just a weird hump in concrete suddenly in garage

[@mts7274]

I have the answer...

[@jdr03272]

How is this fixed?

[@Sonikbytes]

Having similar problem with my home in Gilbert. So gutters will help with this issue? Will I need to have concrete piers installed? and will I have to get rid of my automatic drippers system for plants?

[@ConcreteRepairman]

Settlement is the cause of interior floor heave. By controlling what's causing settlement you control the outcome of how extreme interior floors heave. Call my office 602-418-2970 I will be happy to come out free of charge and evaluate your situation and show you the evidence of what is actually going on.

[@Sonikbytes]

what is your name sir? I will be giving you a call thx

How do you fix it ?

[@mavirek]

We’ve complained that our condo-townhouse has erosion out the back to a canal that passes behind the building. When deck restoration was started, you could see that fill from under our concrete slab had eroded a good 8 feet under our living room to the back patio. Our tile floor shows a fine crack from back to mid-living room. Should we be concerned, or is it normal to have voids under your slab? Will a 4 foot, wood plank retaining wall be enough to hold the fill from eroding into the canal-the townhome is elevated over the canal by about 6-8 feet? We alerted Florida Building Code Enforcement, who issued the permit for the deck restoration, but they were apathetic.

[@ConcreteRepairman]

You need a Civil Engineer. The engineer will draw up the repair plan. Some engineer firms also do their work, which is likely going to be the best. In the end you will have certified repair work done certified by a licensed engineer, this will help sell your home.

[@mavirek]

@@ConcreteRepairman The deck is common area behind my condo, so the restoration was done by the Assoc. The outside of the condo, including foundation I assume, is the responsibility of the Assoc. Having noticed the void under our foundation as they demolished the deck, we told the Assoc. and the local Florida buildings dept (same people who issued the permit for the deck restoration). Neither cared. We took pictures, but that's where the issue comes to a standstill . . . until the erosion levels my home. Was just wondering if this common, to pretend it doesn't matter until the building foundation snaps?

[@ConcreteRepairman]

@@mavirek They're not gonna argue with civil engineering. Likely and out of pocket expense for you however you'll sleep better at night.

[@TXCAMSS1]

I have a crack in foundation and live here in Texas. I’ve had foundation companies come out and say my home is off about 4” on the right side. $23k to repair since I want steel piers and that’s putting piers all round and about 8-9 internal. I looked into my own structural engineer and he said no repairs needed at this time since slope is within tolerance and gave me recommendations. What would you recommend to use to seal my crack? Engineer said epoxy injections but I really don’t want to spend $3-5k on this crack and come to find it reopens in a year or so... Any suggestions?

[@Ainitariq]

Most of these foundation companies are scammers, they are in the business to sell you piers NOT the solution. We had a guy came over and told us we had a void under our concrete floor by stomping his foot and said, see it's hallow and told us our house was sinking. We found out the previous owner had stabilized the foundation and had lifetime warranty for peirs and that guy happened to be working for the same company the owner had used. I told him to come out and take care of the problem he discovered, he said I didn't need anything. I would recommend to bring in other foundation guys for their opinion (not just one) and see what they have to say. You might just have some concrete shrinkage and not too serious. Just make sure the drainage is proper.

[@dianecandoflamtaps9557]

Can you give me a guesstimate of what repairing cracks in a similar indoor concrete foundation, but not as extensive. The cracks are less than 1/4”. The buyer is saying it will cost $35,000 to repair and wanting to lower the price by that amount. Thanks Diane
