Garage slab slope to exterior

[Brandon Whitmore]

Can someone point me to the code requiring a garage slab to slope to the exterior. I can't find my book, and am in a hurry (IRC- new construction).

Thanks.....

R401.3 Drainage. Surface drainage shall be diverted to a

storm sewer conveyance or other approved point of collection

so as to not create a hazard. Lots shall be graded to drain surface

water away from foundation walls. The grade shall fall a minimumof

6 inches (152 mm)within the first 10 feet (3048 mm).

Exception: Where lot lines, walls, slopes or other physical

barriers prohibit 6 inches (152 mm) of fall within 10 feet

(3048 mm), the final grade shall slope away from the foundation

at a minimum slope of 5 percent and the water shall

be directed to drains or swales to ensure drainage away from

the structure.Swales shall be sloped a minimum of 2 percent

when located within 10 feet (3048 mm) of the building

foundation. Impervious surfaces within 10 feet (3048 mm)

of the building foundation shall be sloped a minimum of 2

percent away from the building.

From the 2000 IRC,

R309.3 Floor surface.

Garage floor surfaces shall be of approved noncombustible material.

The area of floor used for parking of automobiles or other vehicles shall be sloped to facilitate the movement of liquids to a drain or toward the main vehicle entry doorway.

Thank you gentlemen. My wireless router took a dive, and I couldn't find my book, since I don't use it much any more. Unfortunately for all of you, I'm back on- line..[:-tong2]

The house I inspected yesterday had a slab floor in the garage, with crawlspace below (wood framed structure). The slab sloped back in towards the house. (oops). I can't wait to see how they will correct this one.

Besides the garage slab floor issue, the entire roof is going to be ripped off and replaced. Bummer.

They may be able to install a drain at the back of the garage?

BTW, I'm told garage floor drains are the only way to go out on the prairies. Prevents the door from freezing to the slab.

That's a good point John. After the first big freeze every year, we spend about a week fixing broken garage doors and openers.

I've never heard of the freezing issue before, of course, it doesn't freeze around these parts much.

I've heard that door contractors stock up on springs during cold weather though....
