Created slope on exterior patio for drainage

Patio Drainage Correction

Creating a slope with a shavemaster and diamond grinder

The exterior patio/covered entry was part of the building slab and was poured flat with a smooth troweled finish. Heavy rain and wind resulted in water puddling in entryway. We were hired to create a slope away from the building so water would drain properly. We utilized a shavemaster (machine with 50 sawblades). Each 1 foot pass shaves off approximately 1/8" of concrete. After each pass with the shavemaster we diamond grind to remove ridges and smooth out the concrete. After we completed the slope correction the area was coated by others.
