When it rains, the water usually flows off the road and into the nearest storm drain. If your property is adjacent to a road, it’s essential to understand how road drainage works and what you can do to ensure that the water gets away from your property and not onto it. Water damage can be severe and costly to repair, not to mention the inconvenience of dealing with the issue.

Surface Solutions shares a brief guide to road drainage so you can better understand how it works and identify potential problems. We’ll also give you tips on maintaining your pavement.

Importance of Road Drainage

Road drainage is vital for several reasons. First, it helps improve the road’s safety by reducing the risk of hydroplaning and slippery conditions. Additionally, it can help improve the road’s efficiency by preventing potholes and other damage caused by water accumulation.

Design of Road Drainage

Road drainage is typically designed by engineers who consider many factors, including the amount of rainfall in the area, the slope of the road, and the type of soil in the area. In some cases, computer models may be used to design drainage systems.

Drain Construction on Roads

Drainage systems are typically constructed by excavating a trench along the side of the road and installing pipes or other structures to collect and direct water away from the road. Occasionally, catch basins or culverts may be installed as part of the drainage system.

Common Problems with Road Drainage

Common problems with road drainage include clogged gutters, broken pipes, and collapsed culverts. Regular maintenance can prevent these problems.

Types of Road Drainage

1. Gutters & Culvert

Gutters are typically used to collect water from the sides of the road and direct it to a catch basin or culvert. Culverts generally allow water to flow under the road without causing damage. You will need to consult a paving contractor to determine if road gutters suit your property.

2. Crown

Most roads are crowned, meaning they are higher in the center than at the edges. It ensures water drains off the road and does not pool in the middle. The crown also helps to direct water toward the sides of the road, where it can be safely discharged into a drainage ditch or culvert. The gutters and channels allow water to flow away from the road surface and help to prevent flooding and erosion.

If the crown is too steep, water will run off quickly and can cause erosion. If the slope is too shallow, water will pond on the road surface and can lead to flooding.

3. Catch Basin

If you live in an area that receives heavy rains, you may have noticed that some roads are equipped with catch basins. A catch basin is a drainage structure used to collect and store water until it can be discharged into a pipe or other outlet. Catch basins are typically installed at low points in the road surface where water is likely to pond or flood. They are often used with pipes to direct runoff away from the road surface. Catch basins help to collect runoff and prevent flooding by directing water away from the road surface.

You will need to consult with a paving contractor to determine the best location for a catch basin on your property.

You should also clean debris from catch basins regularly. It will ensure they can function properly and prevent blockages that could cause flooding.

4. Cross Drain

If your area frequently faces heavy rains, adding cross drains to the road is a good idea. Cross drains are small trenches placed perpendicular to the road at regular distances. They help to collect runoff and direct it away from the road surface.

It is crucial to maintain proper road drainage to prevent flooding and erosion. If you are unsure about the condition of your road, contact a paving contractor for an assessment. They will recommend the needed repairs and solutions.

5. Dry Well Installation

Another option for managing runoff is to install dry wells. Dry wells are pits that are filled with gravel or other porous material. They are used to collect and store water until it can percolate into the ground. It is an excellent option if you have space on your property and want to manage runoff in an environmentally friendly way.

6. Pipe Installation

If your space is limited, consider installing pipes to direct runoff away from your road. Pipes can be buried underground or placed above ground on supports. They should be sloped so that water flows away from the road surface and does not pond or flood. You will need to consult a paving contractor to determine the best type of pipe for your needs.

7. French Drain

A French drain is an underground system consisting of a perforated pipe surrounded by gravel or other porous material. French drains collect and store water until it can percolate into the ground. These drains are often used in areas where the soil is not porous or with a high water table. Consult a paving contractor to determine if a French drain suits your property.

8. Pervious Pavement

Pervious pavement lets water pass through it. It can be made from concrete, asphalt, pavers, or other materials. Permeable pavement is often used in parking lots and other areas where stormwater runoff needs to be controlled.

Contacting a paving contractor is the best way to ensure that your pavement has proper drainage. They will assess the situation to recommend the best course of action.
