Maximum Slope For A Garage Floor

If the floor is hand screeded and isn t re leveled during the finishing process you may get a few minor birdbaths with the 1 8 ft slope but nothing a quick squeegie won t fix.

Maximum slope for a garage floor.

The building code requires that a garage floor be sloped towards the door but does not specify a minimum slope. The apron extends the width of the garage floor. For a garage with two way traffic there is typically 180 feet of ramp two end bays of 28 feet and two spandrel widths of 1 foot. Determine the ramp slope based on the requirements of the structure through los considerations and the expressed purpose of the garage.

For improved efficiency the garage with two way traffic with end bay parking must have 180 ft. The apron s length depends on the required slope more length is needed to reduce steep slopes. Determining the angle of your floor s slope provides a simple method to level work surfaces in the garage. It is usually 1 8 to 1 4 per foot.

As a general rule of thumb most floor to floor height requirements range from 10 to 12 feet. Actually a very slight slope like 1 16 will get rid of the water with a little help from a squeegie. 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.
