SAND AND GRAVEL MATERIALS IN TROUTDALE, OREGON
Troutdale Sand & Gravel is one of the oldest sand, gravel, and ready-mix concrete companies in the greater Portland area. Richard Knarr started the company in the early 1920s on the banks of the Sandy River near downtown Troutdale. Sand and gravel materials were dredged from the Sandy River and sold at the plant. Concrete was delivered to various job sites with sack cement and a portable mixer.
