How high should a ramp be?

Here are some factors that should be considered: Stairs typically run about 7.5 inches high each so for three stairs a standard rise or height would be about 22 inches. The ADA [Americans with Disabilities Act] recommends 1 foot for ramp for every one inch of rise.

How do you slope a concrete ramp?

To create the slope of the ramp, build the sides of the form with pieces of plywood cut at an angle along the top. The key to shaping the concrete into a slope is to use a stiff mixture; if the concrete is too wet, it will slump down to the bottom of the ramp, seeking its own level.

How do you calculate the rise of a ramp?

Divide the length of the ramp by the height. This will be the second number in your ratio. The first number is always one. If the ramp measures 12 feet long and the rise is 2 feet, you would divide 12 by 2 to get 6, and your ratio would be 1 to 6.

How much concrete do I need for a ramp?

Multiply the length of the ramp times the height of the ramp. For example, if the ramp is 3 yards long and rises 1 yard, you would multiply 3 by 1 to get 3 square yards.

What’s the best way to build a concrete ramp?

Whether your concrete ramp is like this one or you’re matching two different heights (going from ground level and matching a floor level) you’ll want to set the top of the forms as your finished ramp level. It’ll make it a lot easier to pour and finish the concrete later on. step 3. What concrete mix to use for your ramp

How is the slope of a concrete ramp determined?

Screw your forms together and use metal pins to secure them in place. The slope of this concrete ramp was determined by the slope of the embankment, so we set the forms on the sub-grade, leveled them across (east to west) and pinned them in place using metal stakes that had holes in them.

How big of a slump do you need for a ramp?

When I call to order the concrete, I tell the batch person it’s for a ramp and to make sure to batch the concrete at a 3 inch slump. Slump is how “wet” or “dry” the concrete is mixed at. A 1 to 4 inch slump is quite dry, 5 – 6 slump is looser, (too wet for a ramp), and a 7 – 10 slump is very loose or watery.

How big of a concrete ramp do I Need?

4 inches thick is good for sloped sidewalks, walking paths, and wheel chair ramps. 6 inches thick is better for vehicle traffic and heavier use. When the concrete arrives, tell the truck driver to mix the concrete to a 3″ slump.

How to form, pour, and finish a concrete ramp?

We poured the concrete at about a 4″ slump and the mix held its slope just fine. Any looser and it would have sagged too much. Fill the forms with your concrete mix using a concrete rake like I am in the previous picture. Once the forms are filled, use a concrete screed and screed “up hill” by dragging the screed on top of the forms.

What’s the best way to build a ramp?

IF YOU’RE RAMP IS SMALL: You can use a bag mix like Quikrete and mix it in a wheel barrow. Just make sure it’s a firm but workable mix when you mix water with it or it’ll want to sag and not keep the proper slope.
