Penetrations are the most common leak points in any membrane. A boot is a molded rubber or membrane sleeve, or a stack of detail plies, that wraps the pipe and laps onto the field membrane, finished with a clamp or sealant at the top. Grouped pipes too close together for individual boots are a classic problem detail.
Six conduits through the deck in a cluster, no way to boot them individually, get a pitch pocket.
