Poor drainage can cause flooding in your building, and also accelerate degradation of your new asphalt surface. Water can destroy a driveway or parking lot because it will pool under the surface and wash away material and the asphalt (or concrete) will collapse in on itself. In addition to this collapse destroying that specific spot, it will also compromise the structural integrity of the surrounding material. This is because the protective seal is now broken which means water can get in and under the protective barrier and further erode away material or water can freeze and make cracks. Weeds can also start to grow in these locations and speed up the degradation even faster.
These problems can be easily avoided through the proper use of grading and drainage. Your driveway or parking lot should have the proper graded slope that pushes water away. If you have a large amount of water to divert, then a concrete curb is also a good idea. Proper drainage allows heavy rainfall to be diverted away from your building and parking areas. If your parking lot has standing water, or your driveway channels water into the garage, then you likely need new drainage solutions. We can go over your options, including curbing, regrading, French drains, and other options.
