California brick

Remillard Brick Company, Pleasanton Yard


In 1861, three brothers from Saint-Valentin, near Montreal, Canada, came to Oakland, Alameda County, California, to establish a brickyard. They were Pierre (Peter) Nicolas, Hilaire, and Edouard (Edward) Remillard. Their firm was named Remillard and Brothers, and they opened an office at Clay and 2nd streets, Oakland, and a brick plant in nearby Brooklyn. In 1879, the firm incorporated to become the Remillard Brick Company. Peter N. Remillard was president, Philip Hilaire Remillard was vice-president, and P.H. Lamoureux was secretary.

After establishing brick plants at Greenbrae, San Pablo, and Hayward, the Remillard Brick Company purchased the
Black and Cory brick works, Pleasanton, in March 1882. This property was located south of Stanley Blvd. at California Avenue, 1.5 miles east of Pleasanton, and extended eastward near the present water slide inside the Shadow Cliffs Regional Park. The original property contained 30 acres of clay deposit and field kilns. The clay was sand loam, 25 feet thick, located a quarter mile from the plant on the north bank of Arroyo del Valle. Dragline scraper was used in the clay pit. Common brick made here was shipped to Oakland by the Southern Pacific Railroad, which built a spur line to the brick plant at Remillard. Three new kilns were built in 1882, and 65 men were employed.

In 1890, the company purchased additional acres of land from landowner Bernal adjacent to their works, and added two 16-compartment Hoffman kilns, each with a large smokestack, 130 feet tall, similar to the preserved structures seen today at their Greenbrae yard. These Hoffman kilns were housed inside a large wooden building, 380 feet in length, that served as driers. The kilns were 150 feet in length, about 60 feet wide, and 20 feet high, containing 20 compartments, and fueled by coal. Each kiln had a capacity of firing 8 million bricks per year. Each Hoffman kiln was supplied by bricks molded initially in two clay mixing mills behind the kilns.

The mill contained a receiving hopper, elevator, screens, disintegrator, pugmill, and brick molding room. These mills were situated along a raised narrow-gauge railroad that transported clay from the pit to the mills on train powered by electricity. A powerhouse containing a 120-horsepower engine fueled by oil provided the power to run all of the machinery. The bricks were made using six-brick molds. The bricks were dried either in the drier racks in the field or inside the drying sheds. Near the creek was situated a mess house, office, and 25 cabins to board the workers. They increased the employees to 130 for six months per year. This plant became Remillard's largest manufacturer of bricks, producing 17 million per year by 1898.

In 1926, in modernizing the operations, the four clay mills were replaced by a single mill built next to the powerhouse. This mill doubled the daily output from 23,000 to 46,000 bricks. The clay pit doubled in size as it expanded eastward towards the kiln property.

Most of the red common brick used in buildings in Alameda County from 1881 to 1935 came from the Pleasanton plant. Local examples of this brick can be seen in downtown Pleasanton at the Johnston and Arendt buildings on Main Street and the Pleasanton Firehouse No. 1 on Railroad Avenue in Pleasanton. In June 1935, a fire destroyed the brick plant and it was permanently closed. Remillard transfered the Pleasanton operation to San Jose, where they had another brick yard. The plant, kilns, and smokestacks were razed in 1938. The Pleasanton property was leased to G and M Gravel Company and perhaps others to excavate the gravel, which has completely altered the surface of the brickyard today. Pacific Gas and Electric placed a substation on part of the clay pit.

Remillard Brick

Common brick is dark red to red-brown, with visible white and gray clasts on the surface, which can get up to an inch or more, and abundant holes and pits. White clasts are angular rhyolite fragments and feldspar, gray clasts are quartz and metamorphic rock fragments. Yellow-brown flashing is visible on some surfaces. Some overburns are present. Rough, gritty surface texture, coated with fine sand grains of subangular white quartz, some stained orange, black iron oxide, and magnetite. edges are irregular and rounded. Corners are dull or broken. Lip is present on the top edges of some bricks. Occasional transverse grooves on sides. Bottom face has a flat surface which looks similar in texture to the sides. Top face shows flat surface with holes and pit. The interior is composed of 2 percent subrounded, iron-stained, and white massive quartz, greenish-gray sandstone, cream feldspathoid, subangular white rhyolite, subrounded, often flattened yellow clay, and subangular metamorphic rocks, all less than 3/4 inch in diameter, in a porous, orange-red sandy clay body. This brick was made using the hand-molded, sand-struck, soft-mud process. Length 8 1/4 - 8 1/2, width 4 1/8, height 2 1/2 inches.
