Slippery Home Made Ramps...Help!!

[hemi]

I made a set (4) of ramps out of 2" x 12"s to get a late model corvette high enough off the ground to then use a low profile floor jack to lift the car properly. Each ramp is 4 foot long with a 2 foot long piece stacked on top and screwed together. The leading edge of each is cut on a 30 degree angle and I added 2 x 4 stops.
The first time I used them on my smooth concrete garage floor I spit one out the back of the car at least ten feet. I need to add some anti slip material ie.
sticky rubber tool box liner or something under the ramps. Anybody have any experience in a similar situation that worked well.?
Thanks for your thoughts.

tie a rope to the front ramps

Glue some 60 grit sandpaper to them.

I thought about the stick on stair tread strips, but they work well with rubber soled shoes not super smooth concrete.

Maybe a rope is a bit rudementary for vette ramps, so better yet affix peices of nylon webbing strap to each ramp. set the front ones in place, drive up (so your tire is over the strap) then set the back ramps in place. your back ramps wont kick out unless it pulls the front ramp with it.

Buy some good quality oil-based black paint.

Mix in some carbide sandblasting media.

Paint.

Or paint the bottoms with contact cement. After it dries it'll be a rubbery coating. As long as you don't put some contact cement on the garage floor they won't stick.

BTW, how does contact cement know to stick only to itself after it has dried?

My pop made some ramps the same way as you describe with stacked wood. When he made his, he designed them so that a 1/2" bold stuck out of the bottom of each ramp. He then drilled 1/2" holes into the concrete floor in his garage so that each bolt would just drop into the holes thus securing the ramps inthe floor where he always wants to to use them.

attach either old carpet, carpet padding, or rubber strips to the bottom so they will grip the floor
paint the top and throw some sand on for top grip

Kinda what I was thinking as a fix

Ohh...

You need something to grip the floor not the tire...

<--- Not paying attention.

You could cut some strips from an old tire and screw them to the bottom of the ramp.

Nail and glue some strips of shingles on them.

Cheap paint and sand on both sides. The sand/paint won't slide on the floor.
Safety wire to the wall isn't a bad idea either.

The roof shingle thing would also work, but would involve nails which might drag their heads on the concrete.

I have the same problem with my steel ramps that have rubber feet. My new garage floor is so smooth that the ramps slip away if I try to drive up on them.
My solution is to lift my vehicles with my floor jack and put the ramps under the tires.
I can drive down off them, but not up onto them with the smooth floor.
