Typical Garage Floor Slope

The apron s length depends on the required slope more length is needed to reduce steep slopes.

Typical garage floor slope.

The apron extends the width of the garage floor. If the slab elevation at the trench. Minimums are limited to 8 feet 2 inches for van accessible structures and 7 feet for standard parking entrances. The apron in front of the garage smooths the transition for the vehicle from the driveway into the garage and acts as a barrier to debris and moisture.

As a general rule of thumb most floor to floor height requirements range from 10 to 12 feet. Aci 117 90 standard specifications for tolerances for concrete construction and materials gives a level alignment tolerance of 3 4 inch for top of slab elevation of slabs on grade. 7 inches sounds like too much both visually and from a walkability standpoint so the most i m going to consider is 3 5. The garage is 28 ft deep so 1 8 to 1 4 inches per foot means the slab shoub be 3 5 to 7 inches higher at the end opposite the door.

A 2 slope will probably ensure better drainage we could also find no slope tolerance for use when a floor slope is specified. Determining the angle of your floor s slope provides a simple method to level work surfaces in the garage. Determine the ramp slope based on the requirements of the structure through los considerations and the expressed purpose of the garage.
