We meet or exceed standards set by NCMA.

NCMA is very similar to ICPI, but we partner with them in regards to Segmental Retaining Wall  (SRW) system education.  SRW systems are the most common type of retaining wall system in the Pittsburgh area due to their ability to withstand our harsh freeze/thaw climate, with a minimally invasive installation process.  We are certified by NCMA, and continue our education yearly.
