Catch basins and storm drains play a critical role in managing pavement runoff and connecting to the existing storm drainage system. They ensure water flows effectively during heavy rains, preventing pooling or flooding in your parking lot or paved areas.

At River City Sealcoating, we specialize in repairing and replacing catch basins and storm drains to maintain their structural integrity. Over time, water exposure and natural wear can compromise these essential systems. By addressing issues proactively, we help protect your property from the costly damage caused by floodwaters during the next storm.

Understanding the Difference Between Catch Basins, Storm Drains, and Storm Sewers

Although often used interchangeably, catch basins, storm drains, and storm sewers serve distinct purposes within a drainage system:

• Catch Basin: A catch basin is a ground-level structure designed to “catch” water runoff from paved areas such as parking lots and roadways. It prevents water accumulation by capturing runoff and directing it into the drainage system.
• Storm Drain: The storm drain connects the catch basin to the storm sewer, acting as a channel to carry the collected water away from the area.
• Storm Sewer: The storm sewer is the final destination for the water, moving it efficiently away from the property to prevent flooding and structural damage.

In simpler terms, the catch basin is a component of the larger storm drain system, linking to the local storm sewer. Together, these elements work to provide effective drainage for paved structures like parking lots, roads, and other similar surfaces. Proper maintenance and repair of each component are crucial to keeping your drainage system functioning smoothly and preventing costly water damage.

Although often used interchangeably, catch basins, storm drains, and storm sewers each serve unique functions within a drainage system:

• Catch Basin: A catch basin is a below-ground structure designed to “catch” water runoff from pavement surfaces like parking lots, roads, and other paved areas.
• Storm Drain: The storm drain connects the catch basin to the storm sewer, acting as a channel to carry water away from the collection point.
• Storm Sewer: This system transports the water from the storm drain to its final destination, ensuring effective drainage and preventing flooding.

In simpler terms, the catch basin is a key component of the storm drainage system, linking paved structures to the neighborhood storm sewer. Together, these elements manage runoff from parking lots, roadways, and similar surfaces, keeping them safe and free from water damage. Proper maintenance of all three ensures effective drainage and long-term reliability.

The Impact of Water Damage on Catch Basins

Catch basins and storm sewers are exposed to significant water flow, which leads to deterioration over time. Cracks in the bottom of a catch basin can allow water to leak out, creating a void beneath the structure. As the catch basin sinks into this space, it leaves behind a visible depression or hole in the pavement.

In areas with seasonal climates, such as the Midwest, frost heaving exacerbates the problem. When moisture seeps beneath the catch basin, it freezes and expands during cold weather, then melts, leaving a void. This cycle of freezing and thawing undermines the basin’s structural integrity and contributes to pavement damage.
