If we are grinding a stump we take our stump grinder which looks like this:
You can see the round vertical blade in the picture. That is what grinds down the stump. We move the blade down and side to side. Typically, we grind down 10-12" below grade (the level of soil around the stump).
Once the stump has been ground it looks like this:
Yep, that is right, it is just a big pile of saw dust. Depending on the size of the stump you can leave this pile and it will settle over time. This is where the "stump grinding" process stops.
However, if you don't like the look of a pile of saw dust, we can remove some of the grindings and put soil and seed so that it will (eventually) blend in with the rest of your yard.
Sometimes if a stump is small, we can excavate it by hand and remove the entire thing.
Please also note that stump grinding does not necessarily mean root removal-- a tree's root system can be huge and it would be near impossible to remove all of the roots for most trees. However, if you are interested, some surface roots can be ground down like the stump.
I hope this helped elucidate the process of stump grinding and removal. Please feel free to contact us for any stump removal needs 301-603-1080
