Free Flow® curb ramp lets construction vehicles drive safely off a jobsite curb without damaging it, while still allowing water to flow underneath when needed. Built for standard and large-scale construction projects, it’s a straightforward fix for a problem every GC runs into: heavy equipment needs to cross a curb, and the curb needs to survive it.

The Problem It Solves

Curbs aren’t built to take repeated hits from loaded trucks and heavy equipment. Without a proper ramp, you’re either damaging the curb (and dealing with the repair bill or the complaint) or blocking drainage entirely, which creates its own problems when it rains. Free Flow® curb ramp solves both at once, vehicles get a smooth, durable crossing, and water still flows underneath instead of pooling up.

How It’s Built

Steel construction, built to hold up under repeated heavy traffic
Engineered for 6″ to 12″ curb height
Available in 4′, 8′, 10′, and 12′ widths
4′ sections can be bolted together, so you can size the crossing to fit your specific jobsite, and the smaller sections palletize easily, cutting shipping costs
Minimizes ponding, maximizes flow, won’t deteriorate or clog sewers
Easy installation and removal between phases or job sites
Purchase or rental options available

Compliance and Practical Use

Free Flow® curb ramp works alongside your other jobsite compliance equipment, if you’re also managing dirt and debris at a site exit, pairing it with Rattle Track® or Rattle Grate® covers both the curb-crossing problem and the trackout problem at the same entrance.

What curb heights does this work with?

It’s engineered for 6″ to 12″ curb heights, which covers the large majority of standard construction site curbs.

Can I customize the size for my site?

Yes. Since it’s built in 4′ sections that bolt together, you can configure it to whatever width your jobsite needs, from a single 4′ section up to much wider crossings.

Does it interfere with drainage?

No, that’s the whole point of the “Free Flow” design. It’s built to let water flow underneath rather than damming it up or clogging the drain.

Should I rent or buy?

Depends on the job. Short-term or one-off projects usually make more sense to rent. If you’re running multiple sites or expect to need it again, buying pays off over time since it’s built to be reused.

Do I need this in addition to a trackout device?

If your site has both a curb crossing and a debris/mud problem at the exit, yes, Free Flow® curb ramp handles the curb, while Rattle Track® or Rattle Grate® handles what’s coming off the tires.
