Catch basins can be the best friends a parking lot needs in times of wet weather. They’re a first line of any defense from heavy rain, since catch basins gather up and then drain away pavement runoff to avoid your lot having standing water. Standing water isn’t just inconvenient for visitors, and quite unsightly, it’s also an accelerant for growth in damage and cracks across your pavement. Whether you have summer rain or winter snow melting, your parking lot needs well-maintained catch basins for optimal effectiveness.
Catch Basin Anatomy
Catch basins are inlets to storm drain systems, usually featuring a grate that filters out any larger debris. There might also be a sump which is responsible for catching sediment or debris. Water will collect in the basin before it gets to a pipe that connects everything to the underground system routing storm water to a nearby stream or municipal water treatment plant. Catch basins are often made from concrete, and they might be reinforced using concrete collars.
Routine Maintenance Is Essential
A catch basin is obviously exposed to the elements, meaning frequent sources of potential deterioration include water erosion, salt or chemicals in stormwater, and repetition of freezing and thawing in cycles. On top of that, vehicle traffic, aging, and weak mortar can all result in damage that makes catch basins less efficient over time. Parking lot managers need to make sure that a sump gets clean of debris with regularity, either using a vactor truck or a hand unit. Regular inspections of all areas surrounding a catch basin should also happen.
Catch Basin Repairs And Replacement
Routine inspections and sound preventative maintenance will let you find and fix issues prior to catch basins deteriorating completely. However, if you have one that stops working entirely, then trust our veteran staff for inspections of your lot to figure out answers. Based on what causes the deterioration and what your budget is like, count on our industry experts to come up with a plan for total repairs and/or replacements of your catch basin.
In a replacement scenario, our team finds all utilities before excavating the current catch basin before installing a replacement properly connected to drainage lines. From there, we install an iron frame to get the right drainage before we backfill any excavated levels using reinforced concrete or hot asphalt mix. In terms of repairs, we typically install adjustment rings to the catch basin level is reset for effective drainage. We might also add concrete collars for reinforcement of the mouth.
Even in the middle of summer, winter wetness will hit again. Be proactive about protecting your catch basins so your parking lot can stay free of standing water.
