Foundation Settlement

What, as precisely as possible, is the situation?

Has machinery been relocated, new machinery or machine process exceeds load capability of ‘foundation’?

Is there an issue with water table beneath the building?

Has there been recent seismic activity that may be the actual culprit?

Be advised, CR4 members are neither able to see anything in your facility nor are we aware of soil conditions, the world location of this issue, age or condition of the concrete...

Throw us a couple of bones here, we will see if useful suggestions can be offered.

Has machinery been relocated, new machinery or machine process exceeds capability of ‘foundation’? There are not relocation of the machinery..

Is there an issue with water table beneath the building? We are search for soil samples analysis

Has there been recent seismic activity that may be the actual culprit? No sismic

My respectfull request it's to know new general technology to resolve this situation... beside piles, redimension concretes, etc.)

So, you care not if the root cause of the failure is a broken water main or wastewater line, or frost heave, or crumbling concrete (this failing is yet another shopping list of possibilities), or improper initial sizing of footings or stemwalls for the real world load, or improperly compacted backfill, or any other of those silly sort of things. You further care not if reinforcing steel is failed because of concrete fail, or if the concrete failed because of bad steel.

You are only interested in fixing this crack in your foundation.

Perhaps another member can suggest the newest concrete Super Glue to use that will resolve your trouble. My two usual resources for this sort of problem, GlobalSpec and LynDoor Industries, have no useful suggestions, they only have a bunch of silly questions for which I have no answers.

Best of luck in your quest.

He should definitely "listen" for water movement under the concrete (may only be present during heavy rain).

I once located a leak in my incoming mains water in the back yard by sticking the blunt end of a large screwdriver in my ear and "probing" the concrete surface with the business end.

Assuming your problem is not systemic....or improper install...the latest thing I've seen is foam injection, where closed cell expanding foam ingredients are injection pumped beneath slab....the two ingredients are mixed in injection nozzle and expand with great force...look for weight rating per square....

..."Concrete leveling is a great way to restore concrete for an affordable price, and there are a few different methods for getting the job done right – foam injection, traditional mudjacking, and stone slurry grout concrete leveling."...

Depending on the weight and scale involved, you might need hydraulic jacking to actually lift...

On the other hand this expanding grout for splitting rock is good for demolishing slabs as well...

Thank you Eagle...

I don't want to you guys resolve this problem...

I just want to know the most update technoligies to develop..... like "foam inyection", etc. you suggest.

Micropiles

Stone columns

Vibro-Compaction

Screw piles

Grout injected piles

The key word from our original poster is ‘Foundation’.

Unless this categorizing word is misused, we are not sandjacking a sidewalk or a driveway here. A primary structural component of some undefined manufacturing facility (of undefined size or integrity or age or suitability for purpose) is compromised to an undefined extent for an undefined length of time.

Has this foundation settlement affected or damaged water or waste lines, power or communication cabling, fuel lines... ???

Even though our original poster’s request for a COTS solution in a can is unrealized, I believe redfred has offered the correct advice: this issue cannot be effectively evaluated from afar, get some capable boots on the ground at the facility. GA voted accordingly.

Might be that a Graboid exterminator is also in order here.

I'm sure you're right....generally speaking..

But sometimes you just gotta' do the best you can with what you have to work with....

increased its lean to alarming levels of late and has been stabilised to its pre-alarm lean since. An internet search on this topic will yield <...literature with modern procedures to resolve this kind of situation...> in about 0.34 seconds.

You need to find bring in an AEC firm.

find out the reasoning why.

1.) did the foundation actually settle?

2.) or did the fill wash away?

They may have even increased the load. For instance, machinery may not have been moved but two more stories were added to the building a few years ago. The original building plans state the building design is strong enough for five stories but the separate, original soil compression test recommends no higher than a two-story building without expensive pile driving.

Thankfully engineering mistakes are rare but they do happen.

The OP should hire a firm to review the executed plans and perform a site survey. I cannot see either from here.
