≫ Trenching for Utilities
Underground utility installation — including sewer lines, gas lines, and electrical conduits — requires precise trenching to avoid future problems. At Dirterra Excavation, we use the best materials and methods to accurately excavate for utilities with minimal impact to existing landscapes and vegetation.
≫ Stormwater Management
Western Washington’s heavy rainfall can lead to erosion, pooling water, and even foundation damage if stormwater isn’t properly managed. At Dirterra Excavation, we offer site-specific drainage solutions to keep your property protected and functioning year-round. Whether you're struggling with soggy lawns, pooling driveways, or meeting city permitting requirements, we recommend the most practical and cost-effective options to move water safely and efficiently.
Our stormwater services include:
French Drains & Infiltration Trenches – Subsurface piping systems that collect and either re-direct or allow for infiltration to help.
Storm Drains & Catch Basins – Ideal for driveways, parking lots, and large paved areas to control runoff.
Sump Pit & Drywell Installation – Sump pits and drywells are useful tools for both high groundwater and stubborn wet areas. They allow for water to be collected and either pumped or infiltrated to a more optimal location.
Infiltration Trenches – Rock-filled systems that allow water to percolate slowly into the soil, reducing surface runoff.
