A natural builder has constructed a hempcrete wall on his Boulder, CO property hoping the project will be a destination for the hemp-curious who want to see hemp building materials in action.<\/p>\n

Architect Scott Rodwin <\/a>constructed the 5-foot hempcrete privacy wall on his corner property at 15th and Quince Streets in the Nomad Cohousing neighborhood he helped found 25 years ago on Boulder\u2019s north side.\u00a0<\/p>\n

\u201cWe wanted something specifically, that was really beautiful on this very prominent street corner, something other than just a plain stucco wall or another wood fence,\u201d Rodwin told HempBuildMag.\u00a0<\/p>\n

Eamonn McNaughton of Rocky Mountain Hemp Build<\/a> teamed up with fellow Front Range hempcrete builder Phelan Dalton of Hemp Building Company<\/a> to supervise the project over several weeks with teams of volunteers to help cast the hempcrete wall in-situ<\/em> around the corner lot.<\/p>\n

Rodwin, who has built several straw bale homes, said he was very interested in observing hempcrete firsthand, but the fact that most hemp homes are not open to the public was a problem.<\/p>\n

The wall is a \u201cdemonstration piece,\u201d Rodwin said. \u201cThe biggest benefit and the main reason we’re doing this, this is a giant billboard for the beauty of hempcrete wall building, because now everybody can see it any time,\u201d he added.<\/p>\n

Colorado-grown hemp hurd was used in the project provided in super-sacks from the San Luis Valley, processed by Global Hemp Processing. Builders used 10 lb. bags of Type S hydraulic lime in a one-to-one mix with hemp hurd. Because the wall is not being used for insulation, builders also used a small portion of Portland cement in the mix.<\/p>\n

The wall will eventually be capped with flagstone to keep rainwater off.\u00a0<\/p>\n

A stratified look of different earth tone colors was achieved with orange, yellow and maroon pigments mixed in with the hempcrete.<\/p>\n

The stratification was a natural echo of the geological layers in the \u201chogback\u201d foothills of the Rocky Mountains, Rodwin said.\u00a0<\/p>\n

The camaraderie in the hemp building world was observable as other hemp builders traveled to help with the build.\u00a0<\/p>\n

Angel Romero, Jr., founder of in Dodge City, KS-based SucGoCrete was participating that weekend in a Lucha Libre wrestling event in the suburbs of Denver.\u00a0<\/p>\n

\u201cI needed to pick up some supplies from Phelan [Dalton], so I knew I couldn\u2019t miss this,\u201d Romero said.\u00a0<\/p>\n
