Project Support

Our team offers a wide range of project support.

Erosion Control

Our Erosion Control team helps monitor potential environmental risks on all of our projects and for our subsidiaries. Our Erosion Control team handles weekly site inspections, reporting to the Department of Ecology (DOE) and the Department of Environmental Quality (DEQ), and maintenance of the onsite Stormwater Pollution Prevention Plans (SWPPP).


Our hydroseeding team assists our erosion control efforts. When a site needs to be stabilized for an extended period of time, hydroseeding is a great option. We are able to support both Tapani and other contractors with hydroseeding.

Our traffic control team works to help support the field with their flagging needs and occasionally assists the project teams or erosion control team. Having an in-house traffic control department allows us to create our own traffic control plans for engineer review and self perform our project flagging needs. We are able to support both Tapani and other contractors with flagging.

Our material management team works to maximize value for our clients by moving excess materials from one project or dumpsite to another project that needs the material. We crush and screen aggregates to make use of on-site rock as well as screening strippings to create screened topsoil. 

Tapani Materials, Inc. (TM) is one of our subsidiary companies involved in our material management strategy. TM includes the following locations:

    The Rockery is a Landscape Supply company with three locations across Clark County open to contractors and the public. For more information, visit

Our dispatch team works to help coordinate any snow removal needs on our projects as well as for local schools and businesses or contractors. This allows our crews and community to get back to work and school quickly and safely.

Metal Fabrication

With an on-site shop at our Battle Ground office, our fabrication team is able to custom build metal structures to help meet our project needs.

Having sweeping trucks in-house has allowed us to meet all of our project sweeping needs. Our sweepers not only help with our projects but also our subsidiary companies like The Rockery, Section 30 and TEBO. At this time we support Tapani’s internal projects and subsidiaries with this service.

Our vacuum truck service helps the field by cleaning sewer systems, jetting lines and potholing to locate utilities. At this time we support Tapani’s internal projects with this service.


Our trucking subsidiary, Tapani Trucking (TT) manages the trucking and logistics for all of our projects. TT provides dump truck services including transportation of aggregates, asphalt, fill dirt and topsoil as well as moving heavy equipment.  TT is available for hire to contractors, rock quarries and homeowners.
