Excavation Contractors in Five Corners, WA

Terrace ground

Five Corners sits on the flood-built terraces east of Vancouver, where gravelly soils are common. Drywells often work, and trench walls need protection in loose gravel.

Neighbors

Five Corners borders Orchards to the east and Brush Prairie to the north.

Older lines in 1990s homes

Homes from the 1990s are now around 30 years old. Irrigation, downspout lines and sometimes water services are reaching replacement age, and yards that were graded flat at construction often need regrading.

Busy corridors

Major roads near the I-205 interchanges carry heavy traffic. We plan hauling around peak hours.

Drywell checks

Even on gravel, drywells need the right size and location, away from foundations, wells and septic. We test infiltration before sizing one.

Settled grades

Yards graded flat 25 to 30 years ago have often settled toward foundations. Restoring a gentle fall away from the house, combined with tightlined downspouts, is usually the first fix we recommend before considering deeper drains.
