Need a concrete curb and gutter that actually controls runoff and protects pavement edges. Since 2018, Quality Concrete Washington has built and repaired curb and gutter systems for driveways, parking lots, and private roads in Washington, DC with clean lines, correct slope, and durable concrete.
Good curb and gutter work starts below grade. We excavate to the design depth, remove soft soils, and proof-roll when needed to catch pumping or unstable areas before concrete is placed. Base is built with compacted CR-6/21A stone (typically 4-8 inches depending on load and subgrade), then we set forms or a slip-form curb machine line and verify grade with stringline or laser. If the curb ties into an asphalt or concrete apron, we sawcut and dowel into sound material as required for a clean, stable transition.
Washington sites bring tight access, existing utilities, and heavy freeze-thaw and deicing salts, so mix and finish choices matter. We place air-entrained concrete (commonly 4,000 psi with 5-7 percent air for exterior durability) and consolidate properly at the back of curb and gutter pan to avoid honeycombing. Slope is set to move water to inlets or drain points, and we tool joints to help control cracking, typically every 4-10 feet based on geometry and exposure. Finish options include broom-finish on the gutter pan for traction and a clean float finish on the curb face, with neat edges, radius tooling, and consistent reveal.
Customers choose us because we build curb and gutter to work, not just to look straight on day one. You get crews that understand grades, drainage, and how curb lines tie into sidewalks, aprons, catch basins, and pavement sections without creating ponding. We show up with the right equipment, including compactors, laser levels, concrete saws, and curb forms or slip-form setups, and we keep staging tight so businesses can stay open and homes stay accessible. Every proposal is clear about scope, thickness, base, reinforcement where needed, and the cure plan so you know what you are paying for.
Before we leave, we do a walkthrough and confirm line, grade, and drainage, then protect the fresh concrete with curing compound or wet cure as the job requires. Joints are checked, edges are dressed, and tie-ins are cleaned up so the curb and gutter meets pavement neatly without trip hazards or broken corners. You receive a written plan for barricades and cure time, plus guidance on when vehicles can return, typically 3-7 days depending on mix, weather, and thickness. The result is a curb and gutter system that sheds water, protects the pavement edge, and stays serviceable through seasons of traffic and salt.
If you are replacing failing sections, we also handle selective demo, haul-off, and matching new work to existing curb profile and reveal. That includes correcting low spots, rebuilding the base, and resetting grades so water flows where it should instead of into doorways, garage slabs, or landscape beds. For new construction, we coordinate curb and gutter placement with subgrade prep, utility elevations, and paving schedules to prevent rework. Expect straightforward communication, clean job sites, and concrete work that is measured, formed, placed, and cured with long-term performance in mind.
Yes. We break and remove existing slabs, dispose of debris, then re-grade and rebuild the base before pouring new concrete. Demo scope is listed in the written estimate.
Some projects may require permits or inspection depending on scope and location. We can explain typical requirements and coordinate sequencing so inspections do not delay the pour.
We can match common finishes such as broom-finish, smooth trowel, exposed aggregate, and light texture, and we can align joint patterns where feasible. Exact color matching is never guaranteed due to batch variation and curing conditions.
Common causes include inadequate base compaction, poor drainage, missing or shallow control joints, overwatering, finishing while bleed water is present, and improper curing. We manage these factors during prep, placement, and cure.
When the base is stable and damage is localized, repairs like partial replacement, edge rebuilds, patching, or grinding trip hazards can make sense. If the slab is heaved, severely settled, or widely spalled, replacement is usually the durable option.
A properly built concrete curb and gutter is more than a border, it is a drainage system that protects pavement edges, keeps runoff out of structures, and guides water to inlets and safe discharge points. Quality Concrete Washington installs, replaces, and repairs curb and gutter for commercial properties, multifamily sites, and homeowners who need dependable flow lines and a clean, durable finish.
Concrete curb and gutter problems usually start with poor subgrade prep or incorrect grade. If the base is thin, poorly compacted, or built over soft soils, the curb settles and the gutter pan holds water. Once water ponds, freeze-thaw cycles and deicing salts accelerate surface scaling and spalling, and vehicle tires break down the edge. Our process focuses on excavation to competent material, placing and compacting CR-6/21A aggregate, and verifying grade before any concrete is poured so the finished system drains the way it is supposed to.
We build curbs using forms or slip-form methods depending on access and line length, then place air-entrained concrete sized for exterior exposure. Consolidation is handled at the curb face and pan to eliminate voids, and we tool edges and joints for a consistent profile. Joint spacing is planned for the geometry and expected movement, and we protect new concrete with curing compound or wet curing to improve strength and reduce surface dusting. If we are tying into existing pavement, we sawcut clean lines and make stable transitions so the curb line holds up under traffic and plowing.
Whether you need a short run at a driveway entrance or longer curb lines in a parking lot, we can scope the work, measure grades, and provide a free written estimate. If drainage is the main issue, we will discuss flow direction, low points, and where water should be directed before we start. When the job is complete, you will have a concrete curb and gutter that manages runoff, protects your pavement investment, and looks clean and intentional for years.
Call now or send a request and we will reach out within one business day to schedule your free, no-obligation estimate in Washington. We assess the project, review the details, and give you a written quote before any work starts, so you know exactly what to expect.
