The short answer: Car ramps slip on concrete primarily because of a smooth ramp base, an angled approach, or an uneven load. Concrete, while seeming rough, can be polished or sealed, reducing friction. Fix it by using rubber mats, adding grip tape, or choosing ramps with built-in rubber feet. For a long-term solution, consider ramps designed for concrete surfaces.
Concrete surfaces vary widely. Freshly poured or sealed concrete can be quite smooth, offering less grip than aged, rough concrete. Also, if your concrete has a smooth trowel finish, it’s more prone to slippage. The issue is exacerbated when the ramp’s base is flat and hard, making it easier to slide forward as you drive up.
Another factor is the angle of the ramp. Most ramps are designed for driveways with a slight incline. If your concrete is perfectly level, the ramp’s base might not seat properly, and the force of the vehicle’s tires can push it forward. Additionally, any moisture, oil, or dust on the concrete can act as a lubricant, reducing friction further.
Place a non-slip rubber mat (like those used under area rugs) under the base of the ramps. This increases friction. Alternatively, old carpet squares work well. Ensure the mat is wider than the ramp base to prevent side-to-side movement.
You can buy anti-slip tape (often used on stairs) and apply it to the bottom of the ramp. Clean the surface first, then stick the tape on. This provides a rough texture that grips concrete. For a more permanent solution, consider applying a rubberized coating or spray-on bed liner to the base.
Even with a good base, ramps can slide if the vehicle’s wheels spin or if you hit the ramp too fast. Place wheel chocks behind the ramps (on the side where the car approaches) to prevent them from sliding forward. You can also use heavy blocks or bricks.
Approach the ramps slowly and steadily. Avoid spinning the tires. If you have a front-wheel-drive car, the front wheels are the driving wheels, so you need to be gentle on the gas. For rear-wheel-drive, the rear wheels push the car up, which can cause the ramp to slide forward if the front wheels hit too fast.
If your ramps don’t have rubber feet, you can attach them. Cut strips of an old rubber tire or use rubber furniture pads. Glue them to the bottom corners using a strong adhesive like construction adhesive. Let it dry fully before use.
If you’ve tried the above and still have issues, it might be time to invest in ramps specifically designed for concrete. Many modern ramps come with rubberized bases or textured surfaces that grip well. Look for ramps with wide footprints, as they distribute weight better and are less likely to slide.

Always ensure the ramps are on a dry, clean surface. Sweep away any debris. If it’s wet, wait for it to dry or use a towel to dry the area. Additionally, always use ramps in pairs and make sure the car is centered on them. After driving up, engage the parking brake and chock the rear wheels for extra safety.
Finally, inspect your ramps for wear and tear. If the rubber feet are worn out or the surface is slick, replace them. Slippage can cause serious accidents, so don’t take risks.
Yes, you can use coarse sandpaper or anti-slip tape. Simply cut to size and attach to the bottom of the ramp. However, sandpaper can wear out quickly and might not hold up well outdoors. For a longer-lasting solution, use rubberized coatings or actual rubber pads.
Rubber feet can lose their grip if they’re dirty or oily. Clean them with soapy water and a brush. Also, if your concrete is very smooth, rubber might not be enough. In that case, add a rubber mat underneath for extra traction.
It’s risky. If your driveway slopes, the ramp’s angle changes, increasing the chance of slipping. It’s best to use ramps on a flat, level surface. If you must use them on an incline, position the ramps so they point downhill, and use chocks behind them.
