Equipped with an adequate number of catch basins strategically placed in a parking lot, it then becomes important for facility/property managers to perform routine inspections and cleaning of the catch basins.  Inspections should be conducted with the assistance of a reputable parking lot maintenance contractor.  He or she can help you look for the following potential defects:

Defect 1: The catch basin is higher than the surrounding asphalt, causing a trip hazard and standing water around the basin.  This occurs when the stone sub-base underneath the surrounding asphalt settles over time and the pavement becomes lower in elevation than the concrete basin.  To remedy this situation, a contractor can remove the surrounding asphalt and lower the basin by removing concrete rings to alter the height of the iron frame.

Defect 2: Sinkholes are developing in the asphalt adjacent to the basin.  This is the result of one or two occurrences.  The first is when water penetrates the basin through gaps in rings, barrels, or at inlets and erodes the stone sub-base in the surrounding asphalt.  If action isn’t taken quickly to remedy this situation, water will erode the concrete basin and further exacerbate the problem.  The second is when the stone base adjacent to the basin has settled and cannot support the surrounding asphalt.  Depending on the extent of the erosion, it may be possible to remove and replace the surrounding asphalt and fill it to a greater depth or it may be necessary to replace the entire basin structure.

Believe it or not, spring is right around the corner and that means April showers.  As any facility or property manager can attest, excess rainwater can wreak havoc on a building.

Installation of a new concrete basin

Many facility/property managers overlook drainage on their parking lots until it is too late because, from the surface, problems are not easily identified.  But, upon closer inspection of areas in and around catch basins, potential drainage issues can be detected early and repaired before they become a concern.  Catch basins are underground chambers topped with grates.  They allow sand, sediment, and other materials to settle out of storm water before it travels to a detention basin.

Begin by assessing the number and location of catch basins on your parking lot.  During initial installation, parking lots should be constructed with a minimum of 1% slope for efficient drainage.  In many situations, this slope is not achieved uniformly throughout the parking lot and lower spots may exist.  Catch basins should be located in those areas to help water exit the surface.  Read more…
