Catch basins drain away surface water—rain and melting snow. Water sitting in a parking lot can become icy and will damage the surrounding asphalt if its not draining properly. If left to pool, standing water erodes and breaks down asphalt. Maintaining your catch basins is a proactive approach that will save you both time and money. To promote proper drainage, catch basins should be positioned at the lowest points of your parking lot. If you see standing water in your parking lot, there may be problems. You should have the components of the catch basins inspected. In addition, depressions in the asphalt around a catch basin could indicate underlying problems with the lot. Before you try to perform a DIY inspection of a catch basin, remember, the top assembly or steel grate weighs 200 lbs or 91 kg. Our estimators are happy to take a look inside and they take photos of any problems inside your catch basins to be included in your quotes. Once the top assembly is open, the shining light inside the catch basin could reveal damage to the top of the catch basin or broken grade rings (risers) that are allowing water to penetrate beneath the surrounding asphalt. Grade rings or risers are an important component of a catch basin, as they can be added or removed to adjust the level of the steel assembly (remember, it should be below the level of the asphalt to permit proper drainage). There could also be damage in the lower portion of the catch basin where the pipe exits. The area around the pipe is referred to as the annulus and can sometimes crack and crumble allowing the water to go where it shouldn’t. If a contractor only fixes the top of the catch basin assembly and problems below are not addressed, you will have wasted your money and the problem will likely return in very short order. Regular inspections, cleaning and maintenance by a knowledgeable contractor can keep catch basins in good working condition. The cost of regular maintenance is far less expense than lot replacement, damaged vehicles or worse pedestrian injury.
