[Groesbeck Hurricane]

Been working too many weeks of 12 hour days and trying to work two farms. Not enough me...

I need to add fasteners to an existing concrete slab. The slab is industrial in type for heavy equipment. Greater than 4,000PSI concrete.

Hilti seems to be what is being pushed but they do not have deep penetration. Is there another type which would be preferable? Think possible tornadoes or other things.

One of the items to fasten down is a tornado shelter. Others are just to add more fasteners to the walls and add a new interior wall.

Thanks in advance!
