Catch basins (storm drains) are critical components of parking lot paving. They drain stormwater and channel it to the underground sewer, preventing flooding and water damage on your commercial property in Daytona Beach.
If you’ve been noticing pooling water on your parking lot lately, your catch basin is likely broken or clogged.
In today’s article, we talk about pooling water and other signs of damaged parking lot catch basins.
Catch Basins 101
Parking lot catch basins collect rainwater on your property and channel it to storm sewers. They are usually built at the curb line in parking lot paving projects.
Storm drains have a metal grate that acts as a cover and keeps out large debris like sticks, leaves, or trash. Sediment falls to the bottom catch basin and not directly into the sewer.
Clogged Catch Basins
If you see water pooling around the surface, maybe the storm drain is clogged and not damaged. The grate prevents large debris from entering the drain, but leaves, plants, and other objects can still block the drain’s surface.
Moreover, small debris that seeps inside can accumulate over time and clog the catch basin. That’s why you need to check and clean your catch basin regularly.
While rubble can be removed to clear the water flow, your drain will become ineffective if too much sediment collects at the bottom.
How Water Damages Catch Basins
Though it seems counterintuitive, your lot’s catch basin is susceptible to water damage. This is true if the joints between asphalt and catch basin are not sealed or when the water seeps between bricks, blocks, or mortar on concrete structures.
The damage becomes more severe in areas with heavy freeze-thaw cycles. In this case, the water infiltrating through the loose joints freezes and causes expansion. With continued pressure on the pavement above, the grate and the catch basin’s frame will eventually sink.
Crumbling Asphalt Around The Catch Basin
Asphalt can deteriorate due to many reasons. Maybe your asphalt contractor used low-grade materials or didn’t do a thorough paving job.
But if the asphalt around the storm drain is crumbling, it may also be a sign that the catch basin has become damaged and ineffective.
Parking lot paving is always at risk of the elements, especially rainfall and ice. And catch basins are specifically designed to prevent water damage on asphalt pavement. However, a faulty catch basin will cause water to pool on the surface, which eventually crumbles the asphalt.
So, whether it’s pooling water, clogged drains, or crumbling asphalt, you should never ignore the warning signs and put off parking lot repairs.
Inspecting, cleaning, and repairing the catch basin is essential to keep your parking lot safe, clean, and attractive for your employees and customers.
