Two kits were used to create this driveway ramp, which is 18′ long, 22″ from street to the top, and with a 2″ center gap. The amount of kits required depends primarily on the width of your driveway and depth of the curb gap. For standard regulation rolled curb gaps, a single unit of Curb Ramp™ will cover about 7-9 ft.
After you perform a dry run and confirm you have enough material for your particular driveway, lay down a protective layer over the curb surface (so as not to prime the curb surface directly) and tape it down around the edges. We recommend using a durable rubber membrane like a shower pan liner, rubber roofing membrane, pond liner or similar substrate. Next, prime the surface of the membrane to ensure a good material bond to the laid substrate. Then, mix and apply the compound atop the substrate to fill the curb gap as you would normally. After 48 hours, your customized driveway ramp should be dry enough to use. The weight of the material and underlying substrate should provide sufficient stability to keep the ramp in place. Concrete bolts can also be used to fasten the ramp to your curb once the material has cured. If you need to remove the ramp for any reason, you can simply lift it up and move it.
The amount of material required to fill your curb gutter depends primarily on the width of your driveway and depth of the curb gap. Each unit of Curb Ramp™ covers approximately 1.33 cubic feet. For standard regulation rolled curb gaps, a single kit will cover about 7-9 ft. when spread to slope at a 20°-25° incline over 18-22”. A typical double car driveway at 15-18′ wide with a standard rolled curb of about 4″ tall requires approximately two (2) kits.

The finished ramp is semi-porous, which allows for some drainage already. To further facilitate street water drainage at the end of your driveway, shape or “feather out” the ends of the ramp to help guide water safely around it. This prevents the build-up of debris so your driveway entrance remains unobstructed and allows water to easily circumvent your driveway entrance and enter back into the curb channel. In other words, don’t make a hard right angle at either end of your ramp.
Note: For deeper curb gaps, PVC pipe can be installed underneath the ramp to further aid drainage. However PVC installation is NOT recommended for standard rolled curbs gaps, as it can compromise the structural integrity of the ramp. To install a drainage pipe, simply prime the area before laying a 1.5-2″ diameter pipe laterally in the center of the curb gap. Then apply more primer to the top of the laid pipe and spread the mixed material to fill the gap as you would normally.
There are several options which can provide a durable protective coating and textured finish to customize the aesthetics of the ramp surface to your liking. Based on customer feedback, applying a final layer of Quikrete Hydraulic Water-Stop Cement over the surface of the ramp while it is curing seems to work well. Just sprinkle the concrete dust over the ramp to achieve the desired look. You can apply the powder while the ramp is still drying, or at a later time, provided you apply a layer of adhesive first.
If you prefer paint, the finished Curb Ramp can be painted to match your driveway color. While we do not currently sell nor endorse specific paint brands, our customers have found success using a variety of paints available at their local hardware store. Simply explain to the store paint professional that you are painting an outdoor surface that most closely approximates a running track in texture and note that it will need to endure frequent traffic.
