Different question on stump grinding

[ozzy42]

Has anybody here had problems with a driveway,or other concrete slab,settling or raising after grinding a stump close by?

The reason i ask is I did a stump apr.8 feet from a driveway that had a root lifting part of it,and the HO calls me back to see if it was possible the root was still growing bc the d/way appered to have lifted even farther .There was no sign of the stump sprouting. I had ground it down about 12inches below grade.and wide enough to severe all roots going srtaight out the sides.

I have heard of one cracking afterward do to large roots rotting out ,and creating a void.And i know some roots seem to be under stress when cut completely from the main stump,causing them to pop up some when they are cut.Do you think the latter situation would be enough to cause damage to a slab,or foundation?

Thanks

I think the later is the case. It is my opinion that the problem is you had downward pressure on the root going under the concrete as it was attached to the stump. When the stump was ground out that pressure was released and the remaining root "popped up" and may have lifted the concrete.

doubt if it could cause problems to a house foundation or slab but maybe sidewalk....How thik is the concrete?

I am not sure,4-6 inches is the standard for residential driveways,,,,,,I think.

Huh? What did you just say? Seriously, use a period or even just a comma every now and again.

No dice...you just have to learn to interpret.

I never did understand that guy and usually just skip his posts...

Not interested in reading something from someone who could care less about our industry to make a proper sentence...

Driveways aren't prepped and laid like roads. They are easy to brake and it sucks learning that the hard way. I get nervous dropping limbs on them nevermind logs.

Driveways can be a pain, some of them are not more than a couple of inches thick. (mine is over 6 inches, but a friend laid it and I was there when it was done)

I have never had serious issues with concrete slabs, but one never knows, depends on type of concrete (read strength), thickness and how large slab is. I did one in my own yard 20 years ago, and the slab was huge.. never budged an inch afterwards.

Now I have had probelms where patio stones are laid down, fortunately they are fairly easily relaid with minimal cost and effort.

Be careful.. if it cracks it can be a lot of work to fix.

maybe the homeowner is just wrong. It couldn't have grown enough in 3 weeks to be the cause of uplift (armchair analysis). I'm curious to know what makes the HO believe this. Is it the whole slab, or is it broken in to pieces and a small piece was uplifted?

NO,He was right ,it was still lifting.I observed it my self.I did not claim any responsibility for it ,just scratched my head ,and shrugged my shoulders.
I mean ,it was allready lifting 3-4 in before I did anything,but it did appear to have gotten worse.

Ok so repair was needed before the event but now it is worse let us know how it plays out.

Just a thought

I know that lumber cut from log under stress (heavy leaners) will not only bend/contort as the board is released from the log, they are also the ones that develop the worst twist/bow/crook as they dry out.

Could this root be drying out after having grown under stress?
