Here's the problem: I had a polebarn built last year. It has 2
overhead doors that are 14' high and 12' wide. The concrete slopes
toward the doors as it should. But, the concrete extends about 16
inches past the doors. In this 16", the concrete sloops toward the
doors (not to the outside drive) allowing water to seep thru the
overhead door seal and not away from the door.
Questions: Can it be ground down to look ok? Should it be cut out and
replaced? What is the best fix?
It is only about 1/4 inch too high.
I've seen them grind down sections of concrete sidewalk that roots
pushed up. Wasn't watching so I don't know how long it took. But
they did take an inch or more off in some cases. I'd be checking out
rental rates for the equipment to help with that decision. Is the
exterior area part of the slab in the barn? Cause if it is then
you'll have to have it cut off to replace. That would make grinding
Any chance that a gutter could lessen the water coming down in front
of the door? If you could minimize the problem maybe you could live

Can you just cut some sloped kerfs with a diamond saw blade that will
allow the water to drain away without grinding down the whole area?
If that doesn't work, then grinding isn't that big a job. It makes a
mess, but since it's outside, that won't be a big deal. Check yellow
pages or online for concrete cutting and grinding.
I did call 3 concrete sawing companies. One never returned my call,
one said I would have to have a section cut out and replaced at $1K
per door, the other said they could grind it down about 1/4-1/2" for
$650 for both doors.
I am waiting on the original installer to see what he says. I am
hoping he can grind it down at no charge and still look ok. He said he
will stop by in the next few days. We'll see if that happens. I'll try
to keep you all posted.
The installer showed up today. He agreed that it needed ground down.
He cut a groove inside the door about 1/4" deep to use as a border/
guide. He then took a grinder and ground down the area where the door
sits all the way to the outside edge, so that the door sits in a 1/4'
pocket. Now the water should drain to the outside rather than inside.
He was here for about 5 hours, but it looks pretty good, almost like
marble. He said he will come back and do the other door if there is a
I am amazed he even showed up. Then I was almost in shock when he said
he would do it right then. Shows me there are some honest and hard
working contractors in this world.
Hank there are darned few of them out there. Sounds like you got a good
Word of mouth advertising for the contractor is the nicest thing you can do
for him/her. Don't miss a chance to refer this person to others.
