Beveled Garage Threshold

[Big Boi]

I want to make the entrance to the garage beveled. Ive seen people take concrete, and make an angled threshold. But I was wondering if I could take the hand held diamond grinder and add a bevel to the floor?

My garage floor is 1.5-2 inches higher than the driveway. It rains so much down here, that if it was level the garage would be flooded after every storm.

Grinding concrete will be difficult work, but you probably can do it with the right tools. I have never done it so I can't tell you how. You might contact one of your local concrete contractors and see what they could do for you and what it might cost.
When I poured my garage slab, I put a bevel or ramp like that. It does keep the water from being driven under the door. Water doesn't like flowing uphill.

Anybody else done this before? or know if its possible?

It's certainly possible, but it poses some potential problems.

How much of a bevel are you looking for? You're going to expose aggregate at the bevel, so aesthetically, it's going to be apparent that you've altered the concrete.

Depending on how much of the concrete you remove, you could create issues with popouts of the aggregate, or delamination of the finished (flat) surface. You shouldn't have any issue with exposing the reinforcing steel, as it shouldn't be that close to the finish floor in any case.

My concern with using a handheld grinder would be the difficulty in achieving a uniform bevel. Check with some concrete finishers in your area and see who they recommend for something like this.

yes its possible., its a lot of work. you could use a gas chop saw and cut a bevel in or do what i do which was build a ramp.

Rather than retyping the whole thing you can follow my steps herehttp://www.tractorbynet.com/forums/build-yourself/152624-barn-entrance-ramp-install.html

Can you add the angle as shown in the top pic by adding some bonderizer to coat the existing first then pour new on top?

Check out the bevels cut onto the walls of this project..
Cut with angle grinder.

i suppose you could do it, but i wouldnt. I removed the existing ramp before pouring the new one.

I wanted the leading edge of the ramp to be ~2" thick. If you went over the existing the leading edge would be too thin IMHO.

How about removing the "concrete" section and laying a drain with a grid above it. Any water from the driveway will drain away and anything you sweep out of the garage will do likewise before hittting the driveway.

Silly question if looks don't matter why not simply call in a paving company to lay down some ashphalt? Quick simple, and cheap, IMO.

I do need to widen the existing driveway... BUT, I don't want to extend the asphalt into the garage.

I talked to a concrete contractor, and he said that the diamond wheel can achieve what Im looking for. And is the same think he would do. So all in all, HD rents the hand held grinder for $24, the vac for $24, and the wheels range from $49 to $69. My neighbor wants to grind his floors as well. So were going to half the rental.


Will one wheel be enough for 2 one car garages? And which wheel should we buy? The blue or green?

Good luck! Let us know how it goes - as always, pictures are appreciated.

If you do the top idea consider drilling holes every 6" or so in the horizontal and vertical face of the existing concrete and put in some concrete nails (tap in) before you pour it so it will be anchored to the old piece and not likely to delaminate itself.....just a thought ??

If you pre drill maybe 1/8" holes tapping in the nails won't crack off the original concrete.

I ended up having a stamped concrete driveway installed. And had the contractor pour up to the garage floor.
