Stoneway Concrete, founded in 1928 and subsequently acquired by the Gary Merlino Construction Company in 1985, has established itself as a venerable entity in the realm of private ready-mix concrete providers within the greater Seattle area. Boasting a rich history spanning over 85 years, Stoneway has cemented its reputation as a trusted name in the industry. Operating multiple concrete batch plants throughout the local area, the company takes pride in its role as a premier concrete supplier in King County. Additionally, Stoneway cherishes the enduring relationships it has cultivated with its diverse clientele, comprising both local patrons and international partners.

In 1985, Stoneway expanded its operations with the inauguration of Stoneway Construction Supply, further diversifying its portfolio and solidifying its presence in the construction domain. This strategic move allowed Stoneway to offer a comprehensive suite of construction-related products and services, complementing its core expertise in concrete production. Through its commitment to quality, innovation, and customer satisfaction, Stoneway continues to be a cornerstone of the construction landscape in the Pacific Northwest.
