Curb and Gutter

Q: What curb profiles can Jennings install with the curb machine?

Jennings’ mold inventory includes curb and gutter, roll curb, vertical curb, valley gutter and ribbon curb.

Q: How long does it take Jennings to provide a quote?

When given approved plans and a clearly defined scope, Jennings Concrete often provides a quote in five business days or less.

Q: Can Jennings work from a cotractor-provided GPS model?

Yes. All Jennings machine-poured curb is installed using GPS guidance. The contractor may provide the project model, or Jennings can furnish one for an additional fee when needed.

Q: How does curb and gutter fit into the overall sitework?

Curb and gutter establishes pavement edges and follows the grades designed to move stormwater through the site. It also creates connection points for paving, sidewalks, driveways and pedestrian ramps, which is why curb installation has to be coordinated with the surrounding sitework.

It's What We're Known For

Curb and gutter has been a core part of Jennings Concrete’s work for decades. We install commercial curb for site development projects throughout Charleston and the surrounding Lowcountry using GPS-guided Power Curber slipform placement as our primary method, with hand forming used where machine placement is not practical.

The decision is based more on the overall quantity of curb than the length of an individual run. A parking lot may have dozens of short, cut-up sections and still make sense for machine placement because of the total footage involved. Hand forming is generally reserved for tie-ins the machine cannot place and smaller jobs, typically those with less than about 600 linear feet of curb.

Whichever method is used, the curb has to follow the required line and grade and be ready for the work that ties into it next.

Power Curber Slipform Placement

For projects with enough overall curb footage, Jennings uses GPS-guided Power Curber slipform equipment to place curb efficiently and consistently. Parking lots and other sites with numerous shorter sections are well suited to machine placement when the total quantity supports it. Our mold inventory allows us to install a range of profiles commonly shown on commercial and site development projects, including:

Curb and gutter
Roll curb
Vertical curb

Valley gutter
Ribbon curb

Hand-Formed and Installed Curbing

Jennings reserves hand-formed curb primarily for tie-ins and other locations that cannot be placed with the curb machine, as well as smaller jobs where the overall quantity does not justify machine placement. As a general guideline, projects with less than about 600 linear feet of curb are typically candidates for hand forming.

GPS-Guided Curb Operations

All curb placed with Jennings’ Power Curber is installed using GPS machine guidance. This allows the curb operation to follow the project model for line and grade throughout machine placement.

The contractor may provide the project model, or Jennings can furnish one for an additional fee when needed. Establishing model responsibility during estimating helps make sure the curb operation is ready before work begins.

Curb and Gutter Within the Larger Sitework Package

Curb and gutter becomes a reference point for several parts of the site. Paving works to it, sidewalks and pedestrian ramps may connect to it, and the gutter follows the approved grades that carry water toward the drainage system.

That makes line, grade and sequencing important beyond the curb itself. Jennings coordinates with the sitework contractor so our work fits the established grades and is placed when the surrounding site is ready for it.

Once the curb is in, other crews often need to work from it. Our job is to leave that portion of the site ready for what comes next.

Questions Before the Work Starts

When does Jennings use hand forming instead of the curb machine?

Hand forming is generally reserved for tie-ins and locations the curb machine cannot place, along with smaller jobs where the total quantity does not justify machine placement. As a general guideline, Jennings typically hand forms projects with less than about 600 linear feet of curb. For larger quantities, machine placement may still make sense even when the project includes numerous short or interrupted runs.
