Posts Tagged ‘Handicap Ramps’

1 to 12 is the maximum steep ratio of rise to run for a handicap ramp, which means that for every 1 inch the ramp needs to rise it must have 12 inches or a foot of run. I needed to build a ramp up onto a porch 29 inches above the gravel driveway. Following is my solution for the limited space available. It is a very little slope that feels almost like walking on the flat.

I had to double the joists at both ends of the eleven foot span. Notice in later pictures that one of the occupants began washing the siding. It looks so much better now. I also had to reroute the downspout and extend it to again reach the drain pipe it had not been draining into recently. The little details matter.

Notice the tar at ground level. Even though treated wood is rated for below grade (underground use), I have noticed numerous times that it does not particularly rot below grade but does at ground level where it mildews and grows algae prolifically. I do all of the posts with a good quality tar, too. I did not run the deck all the way to gravel so that I would run a mound of gravel to redirect water which was washing out near the foundation. Some little details are not so little.

I detest wasting material. The lumber yard didn’t have 10′ decking boards that I wanted so I had to cut off nearly 3′ of board that was not long enough to use on the 4′ wide ramp. I used some of the scrap for erosion control. A little scrap is a big deal- don’t waste!

I was pleased with the result and so was the homeowner. She gets up and down easily now. The little things make it worth doing a good job.

Classic Pine woodgrain that almost looks like plywood. Would you notice such a little thing?

This turn was the most challenging part of the railing, but it sure makes it sturdy. Notice that the siding is cleaner. Turning every board so that the good side shows takes a little extra effort, but it reaps big benefits in appearance.

Based on what I just said about turning the boards, can you imagine how many knots I hid? The little detail that should also be considered when selecting the side up is the crown or dip of the board. Lumber is cut out of a more or less cylindrical trunk. The grain curves in the board. If the crown is down, the board will bow with a dip in the middle across its width. This can hold water on a flat surface and increase deterioration.

The day is nearing an end and I have a little clean up to do before I talk to the homeowner and head for the house. Another project completed for Decks And Such (www.facebook.com/decksandsuch).
