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.
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.
