Concrete curbs and gutters do a job that most people never think about until something goes wrong. They direct stormwater away from pavement, protect the edges of parking lots and driveways, and define the boundary between paved surfaces and landscaping. In Des Moines, that job matters a great deal. Spring snowmelt and summer thunderstorms can move large volumes of water fast. Without properly graded curbing in place, water pools on pavement, undercuts edges, and damages surrounding soil and landscaping. DSM Concrete Pros installs and repairs concrete curbs and gutters for residential and commercial properties throughout the Des Moines metro.
What Curbs and Gutters Actually Do
Curbs and gutters work together as a drainage system at the edge of paved surfaces. The curb is the vertical or sloped concrete barrier that runs along the edge of a road, parking lot, or driveway. The gutter is the shallow channel at the base of the curb that collects and directs water flow. Together, they keep water moving in a controlled direction rather than spreading across pavement or soaking into surrounding soil.
In Des Moines, this function is critical for several reasons. Iowa averages around 35 inches of precipitation per year. A significant portion of that falls during spring and early summer when the ground is still thawing or already saturated. When stormwater has no clear path to drain, it pools on paved surfaces and creates conditions that accelerate pavement failure. Water that sits on asphalt or concrete seeps into cracks, freezes during cold snaps, and widens those cracks with each freeze-thaw cycle.
Curbs also protect pavement edges from vehicle loads. The edge of a parking lot or driveway is the weakest point of any paved surface. Without a curb to reinforce it, vehicle tires rolling over the edge cause crumbling and cracking that spreads inward over time. A concrete curb keeps that edge intact and extends the life of the pavement behind it.

Types of Curbs and Gutters DSM Concrete Pros Installs
Different applications call for different curb and gutter profiles. DSM Concrete Pros works with property owners to select the right style for the site, traffic loads, and drainage requirements.
Barrier curbs have a nearly vertical face. They are designed to keep vehicles on the paved surface and prevent them from driving over the curb. These are common in commercial parking lots and along roadways where controlling vehicle movement is a priority. The vertical face also makes it easier to direct water flow along the gutter channel.
Mountable curbs have a sloped face that vehicles can roll over when needed. These work well for residential driveways and areas where access across the curb line needs to remain possible. They still provide edge protection and drainage while allowing flexibility in how the space is used.
A combination curb and gutter is a single poured unit that includes both the curb face and the gutter channel in one continuous form. This is the most common installation for commercial parking lots and municipal applications in the Des Moines area. Pouring them as one unit creates a stronger, more water-tight joint than installing them separately.
Straight curbs without a gutter channel are used in applications where drainage is handled by the pavement grade alone or by a separate drainage system. These are common along landscape borders and property edges where the goal is edge definition rather than water collection.
Curb and Gutter Installation in Iowa's Climate
Installing curbs and gutters correctly in Des Moines means accounting for Iowa's freeze-thaw conditions from the start. A curb that is not set on a properly compacted base will settle and shift as the ground freezes and thaws beneath it. Settled curbing disrupts the drainage grade, allowing water to pool in areas where it previously flowed freely.
DSM Concrete Pros compacts the base material beneath every curb installation before forming and pouring. We set the grade carefully so the finished gutter channel directs water at the correct slope. Water needs to move at a consistent grade to flow efficiently. A low spot in the gutter line creates a standing water problem that defeats the purpose of the system entirely.
We also use concrete mixes suited to Iowa's temperature range. Curbs and gutters sit fully exposed to the elements year-round. They absorb direct sunlight in summer and take the full force of freezing temperatures in winter. A mix with the right air entrainment handles that freeze-thaw cycling without breaking down at the surface. Air entrainment is a specific mix property that creates tiny air pockets in the concrete, giving water room to expand during freezing without cracking the slab. DSM Concrete Pros uses air-entrained mixes on all exterior concrete work in Des Moines.
Curb and Gutter Repair in Des Moines
Existing curbs and gutters deteriorate over time, especially in Iowa's climate. Freeze-thaw cycling, vehicle impacts, and years of water flow all take a toll. Cracked, broken, or settled curbing no longer directs water the way it should. It also creates trip hazards for pedestrians and can cause damage to vehicles that catch a broken curb edge.
DSM Concrete Pros repairs existing curbing throughout the Des Moines metro. We assess each section to determine whether the damage is limited to the curb itself or whether the base beneath has also failed. A curb sitting on a settled or eroded base needs base repair before the curb is replaced. Installing new concrete over a failing base produces the same result as the damaged curb it replaced.
For smaller areas of damage, saw-cutting and replacing individual sections is often the most cost-effective approach. We cut clean lines on either side of the damaged section, remove the failed concrete, prepare the base, and pour a replacement section that matches the grade and profile of the surrounding curb. The result is a clean repair that restores both function and appearance.
