Before any foundation is poured, a home’s entire drainage system must be installed, aligned, and inspected. Our team completed the full underground rough-in for this new construction project, ensuring every drain, waste, and vent line is perfectly placed for the layout above.

What We Did

  • Installed all underground drain, waste, and vent lines

  • Set proper slope for optimal flow and long-term reliability

  • Pressure-tested and inspection-ready configuration

  • Coordinated layout with architectural and structural plans

This stage is crucial — once the slab goes in, everything below becomes permanent. Proper underground rough-in ensures the entire plumbing system performs flawlessly for decades.
