Pre–Construction System

Typically installed by a builder during construction, this system easily clogs.

Advantages

• System is installed by builder during construction

Disadvantages

• System sits beside the footer in the dirt and can easily clog
• Usually clogs over time
• Pipe is sometimes crushed and discharge is covered during construction

Pipe and Rock Method

This option uses gravel as a filter. But pipe may collapse. Water capacity and clogging are flaws in the system.

Advantages

• Added gravel serves as filter
• Materials used are inexpensive and readily available

Disadvantages

• System sits beside the footer and can easily clog
• Slits in the pipe may not be large enough to accommodate excessive amounts of water
• Pipe can crush or collapse
• Excessive amounts of concrete may be removed for installation, 12” – 24”

Glue Down Method

Advantages

• Concrete removal is not required, quick to install

Disadvantages

• The cost of the system is not relative to the product or its performance
• Water must enter the home before the system activates
• The system cannot handle large volume water flow
• The bond to the floor can loosen over time
• Water continues to wick up the wall
• The open system allows water to stagnate and contributes to higher humidity

Segmented Pipe Method

Advantages

• It sits on top of the footer away from dirt
• Requires less concrete breakout

Disadvantages

• Gravel used may eventually clog the system
• Large amounts of water may overtake the system
• ¾ of the pipe is closed to water entry
• Some segmented pipe can cause clogging or may leak
• Most are all one–chamber systems; no redundancy
