STANDING WATER PROBLEMS
Drainage problems oftentimes defy simple solutions. That’s when it’s important to work with a Pavement Network member who thinks outside the box and has the ability to call upon personal experiences or those of many seasoned professionals inside the network to get solutions to your drainage problems. Whether it’s ponding water in front of the main entrance to your building (slip and fall hazards in cold weather), wheel ruts filled with water (trip hazard and inconvenience to drivers), or that pesky bird bath in the main entrance roadway that grows algae in the driest of summers, these problems all reflect poorly on a facilities manager. It is our priority to find cost-effective solutions that resolve the problem for good. Below are a few of the many problems you’re likely to come across and brief recommended solutions. If you’re interested in finding a solution to your standing water problem, then call a member of the Pavement Network and get satisfaction.
Problem: Ponding on lot/negative drainage.
Solution: Transitional milling to generate swale in pavement and drain water to inlet structure, existing drain or perimeter of lot where it will percolate into the surrounding ground.
Problem: Standing water in front of building at curb line or front door thresholds.
Solution: Install Aco trench drain to capture water and redirect water underground to existing catch basin inlet.
Problem: Sunken pavement/huge bird bath.
Solution: Shoot grade elevations on parking lot, determine flow of water over pavement, mill pavement, and repave entire area to correct drainage problem.
Problem: Wheel ruts/standing water or trip hazards.
Solution: Mill pavement 3" in depth, sweep base pavement, tack base asphalt, and repave with 3" of new asphalt. Eliminate rutting and standing water.
Problem: Potholes.
Solution: Short-term -- Band-aid patch areas by cutting heels around perimeter of pothole, sweep, tack coat and overlay to eliminate standing water and liability problem. Long-term -- requires full depth repair.
Problem: Sunken utilities/holding water around utility covers.
Solution: Install riser rings and resurface immediate area to correct drainage problem. If utilities are sunken greater than 3", jackhammer 2' around perimeter of utility sleeve, excavate around sleeve, dispose of dirt and debris, pull up sleeve to finish grade and pour concrete collar to prevent slippage down below grade.
Problem: Standing water/ponding (collect water and drain away underground).
Solution: Install a 24" x 24" x 36" deep concrete catch basin inlet to collect water and then pipe water away to an existing inlet structure under pavement.
Problem: Topography of pavement has been altered by numerous overlays.
Solution: Consider milling off entire pavement overlay approximately 3" - 4", conveyor material onto waiting trucks, and dispose of debris off site. Then sweep pavement, shoot grade elevation, determine flow of water over pavement maintaining at a minimum 2% slope, and repave lot.
Problem: Downspouts from roof drains flood building foundation, underground garages or pool water in high traffic areas.
Solution: Connect downspouts to 4" - 6" PVC pipe and run network of drainage pipe underground to carry water away to existing catch basin inlet structures.
Problem: Ground water percolates up through pavement.
Solution: Install a French drain to lower water table and drain away water to existing inlet structure.
