Eighty-five percent of structural damages that occur in homes across Colorado can be attributed to poor drainage. As a homeowner, you can avoid costly repairs by installing an exterior drainage pipe.
What Is an Exterior Drainage Pipe?
It is a waterproofing solution that helps move water away from your home before it stagnates and causes water damage and other problems. This system is mostly used to channel excess water after a heavy downpour or flash storm. Once the foundation is laid, tar coating and a plastic drainpipe with filter fabric and rock gravel are set in place around your home. Exterior tar coating will damp-proof your home while the drainage pipe prevents ponding.
Advantages of Exterior Drainage
Among the benefits of having an exterior drainage system is that water won’t pool around your home’s perimeter. The drainpipes will move the water far out, ensuring no mold grows and no water infiltrates your basement. The other reason exterior drains are beneficial is that they reduce soil erosion and prevent the soil from getting muddy. In addition, if any toxic materials get carried by floods, the drainpipes will move them out so they won’t contaminate the water in your home.
Downsides of Exterior Drainage
Installing exterior drainpipes is no mean feat. The contractor has to remove your sidewalk, decks, and parts of your landscaping. Once installed, these fixtures will require regular maintenance to function at the highest level. Ignore them a bit and sediments and debris will easily clog them and impede water flow, leading to pipe failure.
Drainage Pipe Considerations
When installing exterior drainpipes around the home, contractors always keep the following things in mind:
Drain materials: Exterior drainage pipes should be made from a perforated pipe or rigid drain tile. A flexible corrugated plastic pipe is also an option, but extra care has to be taken to prevent it from being crushed during backfilling.
Drainage boards: They are installed on concrete foundation walls to quickly drain off water to the perimeter drain. Drainage boards are common in areas prone to heavy rains and help prevent the buildup of hydrostatic pressure against the foundation wall.
Placement of drains: The best spot to place a drainpipe is at the base of the foundation footing where silt is less likely to accumulate and cause problems.
Codes and regulations: Authorities in Colorado expect homeowners to adhere to certain rules when they’re building their foundations. These rules specify what type of foundation drainage you can install and where.
Exterior drainpipes can help prevent water from pooling around your home’s perimeter, particularly the foundation. In addition, they might help slow down water flow and stop surface soils from being washed away.
The major drawback with exterior drainpipes is that they tend to get clogged with dirt and fail with time. It’s also easy for the pipes to get crushed by the weight of the backfill. If you neglect your pipes and they start leaking, there’s the possibility that they could contaminate water bodies nearby with nitrate salts.
Exterior drainpipe installation is mostly done during home construction. Afterward, it becomes difficult and arduous as the contractor has to excavate the ground to install or repair them.
What Are the Better Alternatives?
Foundation waterproofing systems like the BasementGutter™ interior drainage system and a sump pump are efficient and durable alternatives to exterior drainpipes. They’re also much safer and convenient. Both systems don’t require deep excavations. The BasementGutter™ goes in the basement’s subfloor and is covered with gravel while the sump pump is placed in a sump basin in the floor.
Whenever it rains and water enters the basement, the BasementGutter™ will collect this water and direct it to the sump pump, which then ejects it. This prevents water ponding and the buildup of hydrostatic pressure.
