A Guide to Concrete and Curb Gutters

concrete curb

For many, concrete and curb gutters seem to function just as aesthetics. However, they play a much more crucial role.

A curb acts as a barrier between the pavement and the road, providing a visual separation. This helps keep vehicles on the road and pedestrians on the sidewalk. In addition, curbs tend to be sloped towards a gutter, directing rainwater into drainage systems. Concrete gutters then channel this rainwater away into the city’s drainage system.

The Benefits of Concrete Curb Installation

There are quite a few advantages to curb and roadway gutter installation.


One of the main reasons people install curbs and gutters is that they provide a physical and visible barrier between vehicles and pedestrians. With a concrete barrier, sidewalks can be safe for cyclists, joggers, and walkers; and vehicles can stay in their lanes.

Better Drainage

One of the primary benefits of roadway gutter installation is to provide efficient drainage. Sloped curbs guide rainwater into the gutters, and the gutters direct rainwater into drainage systems. This design helps to prevent flooding and water damage.

Prevents Erosion

Curbs and gutters also help prevent soil erosion along roadsides. By guiding rainwater into gutters, curbs can help minimize soil displacement.

Helps Guide Traffic

Curbs also help keep vehicles in their proper lanes. Moreover, a physical barrier prevents vehicles from entering restricted areas or inadvertently sliding over onto the sidewalk.

Helps Those With Disabilities

Many curbs have features that help individuals with disabilities. Built-in ramps can help parents with strollers and individuals in wheelchairs.

Protects Property

Because curbs provide a barrier to sidewalks, the chances of damage to landscaping and fences are significantly reduced. While some vehicles may “jump the curb” if they’re speeding, most vehicles in an accident will be cut off at the curb.

Enhances Curb Appeal

Finally, curbs and gutters can contribute to the aesthetic appeal of the street. They provide a sense of order and cleanliness.

Concrete Curb Installation: the Process

Concrete curb installation requires a combination of precision and attention to detail.

Prepare the Site

Before any concrete is poured, the site must be prepared. This includes marking the layout, excavating the area to the specified depth, and ensuring the slope of the curb and the direction of the rainwater align perfectly with the design specifications.

Set up the Formwork

Once the site is prepared, edges are erected along where the curb and gutter will be. This is called formwork. Usually made from metal or wood, formworks shape the concrete.

Create the Sub-Base

The sub-base is the foundation or underlying level on which the concrete is poured. The sub-base, usually made from gravel, is spread inside the formwork area. Machinery is then used to make the sub-base compact.

Place Reinforcements

To prevent the curb from cracking over time, reinforcement bars are placed within the formwork. These bars also help to spread out the weight of loads, which is especially effective in busy areas.

Pour the Concrete

Once the site is prepared, concrete is poured into the formwork. Pouring the concrete is important as it must be uniform and level.

Shape and Finish

Once the concrete is poured, tools are used to shape the surface of the curb and gutter. Imperfections are smoothed out and edges are added.

Cure the Concrete

The concrete is sprayed with a curing agent. This process strengthens the concrete and prevents it from drying prematurely.

Remove the Formwork and Clean the Site

Once the concrete has been cured, the formwork is removed. A professional contractor will inspect the area to ensure it meets design specifications as well as the local requirements.

Concrete Curb Maintenance Tips

Concrete curb maintenance is important if you plan to preserve the functionality of your curbs and gutters for years. Although concrete is durable, years of extreme weather and heavy traffic can deteriorate the area. Here are some ways to maintain your curbs and gutters:

• Inspect regularly: Inspect your curbs and gutters regularly, and make note of any deterioration or damage.

• Fix cracks immediately: Cracks can occur due to heavy traffic or freezing winters. Repair cracks as soon as you can. This will help prevent further deterioration.

• Seal Edges: Use sealants to seal the joints and edges of your curbs. This will prevent water from penetrating the joints and causing damage.

• Clean vegetation growth: The growth of grass and weeds can put undue pressure on the concrete and cause damage over time. Try to clean out any weeds and grass from your curbs and gutters.

• Keep drains clear: Make sure debris, such as leaves or dirt, doesn’t block your gutters. Clogs will prevent your gutters from directing rainwater into drainage systems.

FAQs About Concrete Curbs and Gutters

How often should concrete curbs and gutters be inspected?

To ensure proper concrete curb maintenance, try to inspect your curbs and gutters at least twice a year. In addition, inspect them after any extreme weather event, such as a snowstorm or flood.

What are the signs of deterioration or damage to curbs and gutters?

Signs of deterioration include cracks, uneven concrete, and pools of water collecting instead of draining into the gutter.

How can you prevent water pooling or drainage issues in concrete gutters?

If you notice water pooling near your gutters, you may have a clog somewhere in your drain. Clean debris and obstructions. If water pooling continues, contact a professional contractor and schedule an inspection.

How long do concrete curbs and gutters typically last?

If you maintain your curbs well, concrete gutters and curbs should last about 30 years, if not longer. However, factors such as high-traffic areas and climate may reduce their lifespan.

Are there environmentally friendly options for maintaining curbs and gutters?

Yes, you can use biodegradable cleaners to remove any debris from your gutters. You can also combine your curb and gutter design with environmentally friendly bioswales. Bioswales help drain stormwater.

What are the benefits of professional maintenance and repair services for concrete curbs and gutters?

Even if you have professional roadway gutter installation, it’s important to hire a contractor for professional maintenance and repair services. A contractor can help you address any issues effectively (and immediately). They can also provide long-term maintenance plans that are customized to your needs.
