Concrete Curb & Gutter Installation and Repair in Gaithersburg, MD

A concrete curb is a raised edge that borders a pavement, while a gutter is the channel section that runs alongside the curb to direct water. Together, curb and gutter systems manage runoff, protect pavement edges from vehicle impact, and keep water away from adjacent surfaces and structures. They are common on commercial properties, private drives, parking areas, and sites where drainage needs to be controlled.

Curb and gutter work may involve new installation, replacement of damaged sections, or repair of cracks and broken edges. The scope depends on whether the existing concrete can be repaired or whether it needs to be removed and replaced. We evaluate the condition, the drainage, and the site before recommending a path.

It is important to distinguish private property work from public right-of-way work. Concrete curb or gutter work that affects public streets, municipal infrastructure, or regulated areas may be subject to local approvals, permits, specifications, or contractor requirements. We do not assume authority to perform public-right-of-way work without proper approval.

Curb and gutter sections fail for several reasons, and identifying the problem helps determine whether repair or replacement is appropriate.

Conditions We Evaluate

• Cracks running through curb or gutter sections
• Spalling and surface scaling on the curb face or gutter channel
• Broken curb sections from vehicle impact or age
• Settlement where the curb or gutter has dropped below grade
• Ponding water where the gutter no longer drains properly
• Edge deterioration where the concrete has crumbled along the pavement edge
• Failed transitions between curb, driveway, and sidewalk

Some damage is isolated — a single broken section or one crack — and can be repaired. Other damage is broader, with multiple failed sections, settlement, or drainage problems that may call for replacement of a longer stretch. We look at the overall condition and the drainage performance before recommending repair or replacement.

Curb and gutter work follows a sequence similar to other flatwork, with added attention to grade and drainage.

1. 1Site evaluation — assess the area, drainage, existing conditions, and scope.
2. 2Demolition and removal — break up and haul away damaged curb or gutter sections.
3. 3Layout — mark the line, width, and curve radii for the new curb and gutter.
4. 4Grade — set the elevation and slope so water flows the right direction.
5. 5Base preparation — compact the subgrade and add base material as needed.
6. 6Forming — set forms to the curb profile and gutter dimensions.
7. 7Reinforcement where specified — add reinforcement based on project requirements.
8. 8Concrete placement — pour, spread, and shape the curb and gutter.
9. 9Finishing — tool the edges, finish the surface, and place joints.
10. 10Curing and cleanup — allow the concrete to cure and clean the site.

The grade and slope are critical because the entire purpose of a gutter is to direct water. If the slope is wrong, water ponds or flows the wrong way. We set the grade carefully to ensure the gutter drains as intended.
