Exactly what risks do I run with a remediation that involves compaction grouting to stabalize the soil and chemical grouting to fill in the voids under the slab?
One the the problems we are running into is that the floor was settling during the construction of the internal walls and such. Thus if someone comes in at this point and raises the floor to level, the walls, roof, doors, and such will all be raised as well and end up throwing everything else...
There is plenty of mechanical (plumbings,gas,heat) in the floor. It has been determined that the soil was not compacted properly. Is chemical or foam grouting a technique suitable for releveling and stabalizing a office floor for the long term on such soil?
They mentioned today doing some type of compaction grouting or "foam jacking". Can you tell me the prs and cons for such a procedure? Aslo, most of the research I have found on these procedures deals with outside applications. Is this suitable for a clinic type office where the floor is way...
Well Guys,
Went through with the cone/ Pit compaction test. Interesting, I learned alot. Attached are photo's of the 1+ inch gap under the slab. When making the final cut, the slab actually dropped and pinched the saw blade. I should get my report in a few days...
I've committed to the pit tests and the contracter is on his way over as I write this to look at the areas of slab removal. Tomorrow the testing people are comming over to take their samples. A report will be generated next week. This just keeps getting sader and sader as I was on a...
Do I have to worry about false compaction from the dropping slab? If I'm going to proceed with this and reroute traffic in the building, I would like to be able to rely on this test. Thanks Paul
Based on all of your advice, I have decided to go ahead with the compaction tests and scheduled it for this Saturday. In your opinions, what would be the best location for the pits? In an area of greatest settling, or would the soil in that area be compacted from the dropping slab.
I appreciate all of you taking time to respond. Assuming the floor will not settle any further (although a few internal sona tube footings are just recently starting to appear through the carpet and linoleum), is it possible to relevel the floor with some sort of leveling compound that bonds to...
Yes I do have an attorney and we are learning together. The sad part of it all is there was a soil test done before we started and the report came back recommending engeneered granular fill. Of course I just learn this recently.
Hi all,
I am looking for advice on a office building I had built in 2009. The ground was actuallly scraped in October of 2008. Up here in the Dakotas, it turned very cold and due to the elevation of the existing lot, fill had to be hauled in to reach floor height. The building was scheduled...
