Downspout lead-offs are a 3 to 4 inch pipe that runs under ground from the downspout on the house to the outside surface. Its function is to drain the water away from the house. It consists of digging a shallow ditch 6 to 24 inches deep (depending on the terrain). D-Bug Waterproofing grades the lead-off out to the surface and away from the house or dwelling. In some situations, we have to install a gravel pit sump well.
Sump wells are needed due to grading issues or by code enforcement in certain townships. A sump well is a hole that is dug about 3 to 4 feet deep and 3 to 4 feet across. We either install a sump pit or a 12 to 24 inch pipe with holes. The function of the holes is to let the water drain or seep into the ground.
Next, the hole around the pit is filled with gravel. Then, a layer of fabric is placed over the gravel, followed by 4 to 10 inches of dirt used for planting grass. Certain townships require sump pumps to drain into sump wells, while other townships require both the downspouts and sump pumps to drain into the sump wells. Code would be enforced following the specifications of your particular township.
The purpose of downspout and drainage-related codes is to make sure that water doesn’t end up in someone else’s property. Land around a home should be graded in such a way that water flows away from the home, but not at the expense of your neighbors. D-Bug Waterproofing re-grades yards to slope the terrain away from the house or structure. Re-grading the yard keeps the water from running against the house and directs it to a specific area. In some situations, dirt is added against the house, yet some yards may require removing dirt.
All too often, downspouts arbitrarily direct water straight down into the ground. D-Bug makes sure that water is drained away from your house and into the proper places, such as a dry well or storm sewer.
