ACC operates as a full-service curb and gutter contractor in Fort Collins, handling every type of curb work, from single-section curb replacement and gutter repair to full-length new curb installation and ADA curb ramp construction. Each service addresses a specific failure mode or compliance requirement that Fort Collins property owners face.
Replacing failed curb sections in Fort Collins requires understanding why the curb failed in the first place. Fort Collins's 100+ annual freeze-thaw cycles spall concrete surfaces, snowplow blades chip and crack vertical curb faces, tree roots heave entire curb sections out of grade, and expansive clay soils create settlement that breaks gutter connections. ACC's curb replacement process addresses the root cause. Not just the visible damage, by removing the failed section, excavating and recompacting the subgrade, installing #4 rebar dowels tied into the existing curb at 24-inch centers, and pouring 4,000 PSI concrete with 6% air entrainment specifically designed for Fort Collins's freeze-thaw environment. Every curb replacement meets Fort Collins's standard 6-inch curb reveal height and includes tooled expansion joints for thermal movement.
Full removal and replacement of damaged barrier curb sections, the standard curb type used along Fort Collins streets, parking lots, and commercial properties to contain traffic and direct stormwater flow.
Replacement of rolled curb (mountable curb) sections commonly found in HOA communities and low-speed parking areas where vehicles need to cross the curb line for vehicle access.
Targeted replacement of curb sections damaged by snowplow blade strikes and vehicle impact, the two most common causes of curb damage in Fort Collins commercial parking lots and along city streets during winter months.
Repairing gutter sections in Fort Collins is critical for stormwater management because damaged gutters direct water into pavement structures instead of into storm drains. A cracked or settled gutter creates ponding at the curb line, saturates the asphalt base, and accelerates pothole formation through freeze-thaw action. ACC repairs and replaces gutters, valley pans (V-pans), and integral gutter sections to restore proper drainage flow, eliminate ponding, and protect adjacent asphalt from water damage. Every gutter repair includes grade verification to ensure water flows toward the nearest storm drain inlet at the minimum 1% slope required by Fort Collins's stormwater management standards.
Replacement of integral curb and gutter sections where the curb and gutter are poured as a single monolithic unit, the standard configuration for Fort Collins's commercial and municipal streets.
Replacement of valley pan (V-pan) drainage channels used at intersections and mid-block locations to direct stormwater across streets and into storm drain inlets throughout Fort Collins neighborhoods.
Settlement and grade correction for gutter sections that have lost proper drainage slope due to soil movement, tree root heaving, or original construction defects causing water to pond at the curb line.
Installing new curb and gutter for Fort Collins commercial properties, HOA communities, and new construction projects requires engineering the curb system for stormwater management, traffic control, and pedestrian safety from the start. ACC installs both integral curb and gutter (monolithic pour) and separate curb and gutter systems depending on site conditions, drainage requirements, and municipal specifications. New curb installation includes subgrade preparation with compacted aggregate base, steel reinforcement per Fort Collins standards, proper expansion joint spacing, and curb transitions that meet both the asphalt grade and the sidewalk elevation. ACC handles new curb installation for parking lot perimeters, median islands, access road frontage, subdivision streets, and commercial property boundaries across Fort Collins.
Machine-extruded curb installation using a slip-form curb machine that produces consistent, uniform curb profiles at high production rates, ideal for long runs on new construction and HOA street projects.
Precision hand-formed curb for tight areas, radius turns, curb transitions, and locations where machine access is limited, common in parking lot islands, medians, and retrofit projects across Fort Collins.
ACC installs both integral curb and gutter (poured as one unit) and separate curb and gutter systems based on drainage design, soil conditions, and municipal requirements for your Fort Collins property.
Constructing ADA-compliant curb ramps in Fort Collins is a critical component of any curb and gutter project because federal accessibility law (ADA Title II and Title III) requires compliant curb ramps at every pedestrian crossing point on a property undergoing alteration. Fort Collins's DOTI enforces strict curb ramp specifications including maximum 8.3% running slope, maximum 2% cross slope, detectable warning surfaces with truncated domes, and minimum 48-inch landing at the top of the ramp. Non-compliant curb ramps expose property owners to ADA lawsuits with penalties starting at $75,000 for first offenses. ACC constructs ADA curb ramps that meet both federal ADA standards and Fort Collins's DOTI specifications, including proper slope verification with a digital inclinometer during and after the pour.
Single-direction curb ramps aligned perpendicular to the street, directing wheelchair users into the crosswalk rather than into traffic, the preferred configuration under current ADA and DOTI standards.
Diagonal ramps at corner intersections and parallel ramps along constrained right-of-way locations where directional ramps cannot be installed due to space limitations or grade constraints.
Removal of non-compliant curb ramps and replacement with current ADA/DOTI-standard ramps. Many Fort Collins properties have ramps built to outdated specifications that no longer meet federal accessibility requirements.
Fort Collins's combination of 100+ annual freeze-thaw cycles, snowplow operations, expansive clay soils, chemical deicers, and tree root growth creates six distinct failure modes that destroy curb and gutter infrastructure. A curb repair contractor in Fort Collins must diagnose which failure mode caused the damage before prescribing the correct repair method.
Root Cause: Water penetrates the concrete surface through micro-cracks and pores. During Fort Collins's 100+ annual freeze-thaw cycles, this water freezes, expands by 9%, and fractures the concrete surface layer. The surface "spalls" (flakes and chips away in layers) progressively reducing the curb's structural cross-section. Curbs poured without proper air entrainment (6% minimum for Fort Collins) are especially vulnerable because trapped water has nowhere to expand during freezing. Freeze-thaw spalling is the single most common curb failure mode in Fort Collins.
Root Cause: Snowplow blades operating in Fort Collins parking lots and along city streets strike curb faces at the gutter line, chipping concrete and cracking vertical curb sections. Repeated impacts over multiple Fort Collins winters progressively destroy the curb reveal, reducing the effective curb height below the 6-inch standard and compromising the curb's ability to contain traffic and direct stormwater. Commercial parking lots with frequent snow removal see the most severe plow damage, with some curb sections losing 2–3 inches of reveal height within five winters.
Root Cause: Street trees and landscaping trees planted near curb lines send roots beneath and through curb and gutter sections, lifting the concrete out of grade and cracking it from below. Root heaving is particularly common in established Fort Collins neighborhoods where mature trees have 20–40 years of root growth beneath curb lines. A heaved curb section disrupts gutter drainage grade, creates trip hazards on adjacent sidewalks, and causes separation at expansion joints that allows water infiltration into the subgrade.
Root Cause: Vehicles striking, mounting, or parking against curbs cause impact cracking and structural failure. Delivery trucks mounting rolled curbs to access loading areas, passenger vehicles hitting vertical curbs during parking maneuvers, and vehicles jumping curbs in parking lots all create impact damage that exceeds the concrete's tensile strength. The repeated loading creates fractures that propagate through the curb section, eventually separating the curb into pieces that shift under subsequent traffic loading.
Root Cause: Magnesium chloride and sodium chloride deicing chemicals applied to Fort Collins streets and parking lots during winter penetrate the concrete surface and accelerate freeze-thaw damage. The chemical reaction between deicers and concrete creates calcium oxychloride, which expands within the concrete matrix and causes surface scaling, flaking, and progressive erosion of the gutter channel. Gutters are most affected because deicing chemicals concentrate in drainage channels where meltwater flows and pools.
Root Cause: Much of Fort Collins sits on bentonite clay and other expansive soil types that swell when saturated and shrink when dry. This seasonal volume change creates differential settlement beneath curb and gutter sections, causing them to drop, tilt, or crack at joints. Settled gutter sections lose their drainage grade, creating ponding that further saturates the expansive soil and accelerates the settlement cycle. Properties in southeast Fort Collins and Loveland are particularly susceptible to expansive soil movement affecting curb and gutter infrastructure.
Understanding the differences between curb and gutter construction methods helps Fort Collins property owners make informed decisions about which approach delivers the best performance and value for their specific project requirements.

Choosing a curb and gutter repair contractor in Fort Collins comes down to six factors that directly impact concrete longevity, drainage performance, code compliance, and total project cost. ACC delivers on all six.
ACC has poured curb and gutter across the Northern Colorado region since 1986. Four decades of concrete work in Colorado means ACC understands how freeze-thaw cycles, deicer chemicals, snowplow impacts, and expansive soils destroy curb infrastructure, and how to engineer curb replacements that resist these forces for 25+ years. That experience translates directly into longer-lasting curb and gutter on your property.
Talk to Our Concrete TeamCurb and gutter work in Fort Collins's public right-of-way requires a DOTI (Department of Transportation and Infrastructure) permit, utility locates, traffic control plans, and post-construction inspection. ACC handles the entire permit process (application, scheduling, traffic control, and inspection coordination) so property owners don't have to navigate Fort Collins's permitting requirements independently.
Ask About PermitsEvery curb and gutter project starts with a free on-site visit where an ACC project manager measures curb reveal height, evaluates gutter flow grades, inspects expansion joints, identifies the root cause of each failure, and documents which sections need full replacement versus repair. You receive a detailed written proposal with transparent per-linear-foot pricing within 48 hours. No obligation.
Schedule AssessmentACC pours all curb and gutter with 4,000 PSI concrete with 6% air entrainment, the specification required for Fort Collins's freeze-thaw climate. Air entrainment creates microscopic bubbles that give freezing water room to expand without fracturing the concrete. Many contractors pour curb with standard 3,000 PSI non-air-entrained concrete that begins spalling within three to five Fort Collins winters.
See Failure ModesACC constructs ADA curb ramps that meet both federal ADA standards and Fort Collins DOTI specifications, maximum 8.3% running slope, maximum 2% cross slope, detectable warning surfaces with truncated domes, and 48-inch minimum landing. Every ramp is slope-verified with a digital inclinometer during and after the pour. ADA violations carry first-offense fines starting at $75,000.
