Earthquake Drains

what they are:

Corrugated pipe wrapped in a filter fabric installed with a vibrating mandrel in a grid pattern.

how they work:

Their flow capacity allows a path for excess pore pressure to rapidly dissipate during an earthquake, providing sufficient discharge capacity to mitigate liquefaction and reduce post-earthquake settlement.

why use them:

To help eliminate excess pore water pressure generated by earthquake loading quickly and prevent liquefaction.
