​

Basalt Site Services is an excavation and civil sitework contractor based in Ellensburg, Washington. We serve Central Washington municipalities, public agencies, general contractors, private developers, builders, businesses, and property owners.

​

Our work is performed with excavators equipped with Steelwrist tiltrotators and task-specific attachments. This allows us to complete work efficiently while reducing labor and equipment costs and limiting ground disturbance.

​

We plan and execute each scope with attention to sequencing, site conditions, access, safety, and coordination with owners, inspectors, contractors, and other trades. Our objective is to provide clean, accurate work that conforms to the plans and specifications, reduces rework, and is completed within scheduling requirements.
