I poured a slab foundation for a metal building workshop that required
nailing 2" x 2" strips to the perimeter of the slab to allow for the metal
wall panels to rest on this stepped down area.
I inadvertently nailed this 2" x 2" strip to the area where I was to form a
slope for a 10' roll up door. When I removed the strip in this sloped area
it left a groove underneath the strip that runs the length of the slope.
By Slope I mean a ramped area just below the roll up door to avoid water
from running into the building.
Is there a tool (Wire Wheel, Sander ) that I can use to "take down" some
concrete and smooth out this slope ??
I would like to be able to create an even surface as should have been
intended in the first place.
I know of a few easy fixes, however none will last long. The
problem being that, when you repair concrete in small pieces it breaks
I sugest using a non-concrete material such as "Vi-Tex". It comes
in bags as a powder that you add water to to make either a paste or
batter. It dries incredibly fast and is very strong, also check for
other products like floor levelers and such. Don't go to a Home Depot,
or Lowes they won't have a clue, find a concrete or stucco specific
dealer, they'll have several very good cobncrete fix materials.
If you use the "Vi-Tex, set a form across the area, mix it as a
kind of batter(like pancake batter) use a lot of bonder in the mix,
(concrete bonder can be found at Home Depot or Lowes), also brush
bonder onto the area before you apply the Vi-Tex, about a half hour
before, and let it set a bit. Don't be stingy with the bonder either,
use plenty. Pour the Vi-Tex into the form and concrete patch area and
let iset for at least a day or two so it sets up good and strong, then
strip your form, the form will probably want to stick to the Vi-Tex,
so I would use plywood as a form it will rip apart from the patch
rather than rip the patch from the slab.
If your planing a drive to the building do it asap so the patch
doesn't have a chance to crack and fall out and is held in place by
the new concrete.
Like I said this may only last a year or so but it's what I would
try, I've been doing concrete and buildings for about 12 years now, I
hope I helped.
