Stem Wall MEP Rough-In
Plumber and electrician completed under-slab preparations: waste line penetrations through stem wall, hose bib supply runs, and electrical conduit sleeves. These must be installed before the stem wall cavities are filled.
Pro tip: Coordinate your plumber and electrician to be on site the same day for MEP rough-in — every penetration through the stem wall must be done before the cores are filled. Missing one means core drilling through solid concrete later.
