Another day, another installation of a Methane Barrier in Los Angeles, CA…

April 6, 2011

Terra-Petra’s Deputy Methane Barrier Inspector Richard McClanahan was on site last week to inspect the methane barrier installation at the Wembley Park condos in Playa Del Rey, CA.

The project is in the City of Los Angeles Methane Zone and therefore requires such inspections. Terra-Petra designed and plan checked the methane gas mitigation system for this project.
