Basalt Rock Installation

What This Service Involves

Basalt is the region's signature volcanic stone, ranging from near-black to deep charcoal-gray and available as columns, boulders, and crushed aggregate. Sourced right here in the Pacific Northwest, it lends an authentic, native character to water features, borders, and modern hardscapes. Its dense, hard structure stands up to freeze-thaw and heavy rain without flaking or fading over the years. Designers around Tacoma and Seattle favor basalt columns and boulders as sculptural focal points in contemporary gardens.

Benefits

Authentic, locally sourced Northwest stone; Extremely durable and resistant to weathering; Deep color that anchors modern and naturalistic designs; Available as columns, boulders, or crushed rock for flexibility; Low maintenance and long service life

Our Process

1) Grade the area and confirm bearing for boulders or columns; 2) Lay landscape fabric to separate stone from soil and suppress weeds; 3) Set a compacted base to support and level the basalt; 4) Place boulders, columns, or crushed basalt over the fabric-lined bed and set securely

What Affects the Cost

Form chosen, whether crushed, boulders, or columns; Size and weight of individual feature stones; Equipment and labor needed to place heavy pieces; Site access for delivery and machine placement; Integration with water features or hardscape elements

Best Time of Year

Basalt can be set any time of year, though summer's firmer ground makes placing heavy boulders and columns safer and easier.
