In 1866, Samuel Nicholson of Boston, MA patented his end grain wood block pavers for street paving, and we've brought em back! End Grain wooden blocks were used for street paving in Europe, Australia, and in the USA, and there remain many streets here in the USA still paved with end grain blocks.


The basic theory of Wood Block Flooring is centuries old. The ancients used the end grain of logs as “chopping blocks” because the tough end grain surface could withstand the pounding of hammers without splintering. End Grain blocks were once used out of doors as street pavers. For generations, wood blocks served the needs of city streets in Europe and in the United States, many of which still exist today. 

There remain two wood block paved streets in Chicago. Constructed in 1909, the original and famous “Wood Paver Alley” between State and Astor Streets is one. It is listed on the National Register of Historic Places. In 2012, after 103 years of service the city engineers determined it was time to replace the original blocks. They chose Kaswell Black Locust Blocks for this historic and special landmark. The new Wood Paver Alley is now a beautiful architectural tribute to the integral role wooden paver blocks played in the development of the street system in Chicago and around the country, facilitating the transportation of people and goods essential to the entire nation’s growth and connectivity.

David O. Whitten, historian at Auburn University wrote an article titled “Wood Blocks as Paving Material in the United States and Abroad 1840-1940”. In his article he states that wood blocks for street paving were not intended as an all-purpose paving material, but as a special substance for selected streets. City engineers considered wood blocks appealing for streets near hospitals, schools, churches, and other public buildings where street noise was especially bothersome, and in congested streets with heavy traffic. We believe end grain wood blocks remain a special substance, combining comfort and durability with natural beauty. In addition to our black locust we also offer redwood, mesquite, and pine for exterior patios, walkways, courtyards, and streets applications. “End grain imaged brick” pavers are available as well.

“It is generally admitted, we believe, that as long as they last, the wood block pavements have an advantage over all others. They occasion little noise, they save a great deal of horsepower, pleasant to the hoof, and thus save the health of the horse-as well as some twenty or thirty percent in the wear and tear of vehicles-and as much more, in time, to all travelers through the increased rapidity of passage to and fro.”

-Edgar Allen Poe
