Architects & landscape designers
Evaluate material character, accessibility considerations, drainage, and published specification requirements while the pathway is still being designed.
About PolyFirm
For 20 years, PolyFirm has focused on aggregate stabilization in the Pacific Northwest, working with architects, landscape designers, and contractors who want natural-looking pathways without overlooking the demands of everyday use.
Specialists in the surfaces between buildings.
Paths, gardens, parks, and public spaces often rely on materials that are as much a part of the design as the architecture around them. Gravel and decomposed granite offer a particular character, but they also require careful detailing, installation, and maintenance.
PolyFirm has spent 20 years working in that narrow but important part of landscape construction, helping project teams choose and apply TrailBinder where a cohesive aggregate surface is the right fit.
Our work is rooted in the Pacific Northwest, where wet seasons, varied terrain, and heavily used public landscapes make the performance of a finished pathway particularly visible.
The point is not to change what makes natural aggregate worth specifying. It is to help designers and contractors work with that material more deliberately, from the initial detail to its eventual renewal.
How we work with project teams
A product decision affects more than the first installation. We approach the work as a continuing relationship between design intent, site conditions, contractor execution, and ownership.
Landscape contractors
Translate the details into a workable installation sequence, with attention to aggregate selection, base preparation, application, and weather.
Owners & maintenance teams
Discuss how surface wear will be inspected and addressed over time, including periodic renewal rather than promises of permanent performance.
Where TrailBinder has been used
PolyFirm references include parks, gardens, civic landscapes, educational institutions, and cultural destinations across the region. Examples from the current site include:
Parks & public landscapes
Washington Park Arboretum, Bellevue Parks & Recreation, Seattle Parks & Recreation, and Kubota Garden.
Civic & cultural projects
King Street Station Plaza, Olympic Sculpture Park, and the Bothell Civic Center.
Education
Seattle public schools and Evergreen State College.
Landscape & destination venues
Chateau Ste. Michelle in Woodinville, among other regional destinations.
What we value in a successful project
The best outcome is a pathway whose appearance feels right for the landscape, whose performance has been considered, and whose long-term care is understood by the people responsible for it.
Clear information, from specification through installation
We make current product information and installation documents available for specification and construction review. When a project raises questions about grade, aggregate, curing, or future maintenance, those deserve direct answers rather than broad promises.
