Excavation, grading and drainage

Every yard we build starts with the ground. We clear, dig and haul, shape the grade so water moves away from the house, and compact the base before concrete or pavers go down. It is the least photographed part of the job, and the part that decides how long everything else lasts.

How it goes

How site work goes

  1. Locate utilities

    Underground utilities are located and marked before any digging starts.

  2. Clear and dig

    Sod, roots, old concrete and soil come out and get hauled away.

  3. Set the grade

    We shape the ground so water runs away from the house and off the finished surfaces.

  4. Compact the base

    Base rock goes down in layers and is compacted, ready for what gets built on top.

Questions about excavation & drainage

My yard holds water. Can you fix it?

Usually. Most wet yards come down to grade: the ground slopes toward the house, or there is a low spot with nowhere to drain. We regrade so water moves away, and add drain lines where grading alone is not enough.

Do you haul away the dirt?

Yes. Soil, sod, old concrete and debris leave with us.

Do you have utilities located before you dig?

Yes, every time. Underground lines are located and marked before any digging starts.
