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.
