Bomanite Textured Risers Guideline Specification
BOMANITE CORPORATION has developed five new creations in Textured Risers to help architects achieve a dramatic, yet natural, touch to their architectural concrete paving projects.
The newest addition to the BOMANITE family of products adds a deep texture to step faces. The heavy relief in the BOMANITE textures available are similar to the appearance of textures found in natural stones: BOMANITE’s Cliff Rock Face, resembling a shelf formation of jagged rocks with almost 2″ of relief in the texture; BOMANITE’s River Rock Face, containing oval-shaped rocks on edge averaging about 6″ in diameter with up to 1″ of relief; BOMANITE’s Chipped Granite Face, having a sculpted granite texture comparable to quarried granite stone; BOMANITE’s Slate Face resembling the texture of natural slate; and BOMANITE’s Cantilevered Slate, with the cantilever adjustable from 0″ – 4″.
Whether a project calls for a single step or a cascade of steps, BOMANITE’s new system provides architects with the vertical texturing option needed. Exterior applications include steps, patio edging and decorative planter areas. Interior applications include planter faces, fireplace hearths and indoor steps where a rustic, natural-rock look is desired. BOMANITE Textured Stepliners can also be used in conjunction with BOMANITE — cast-in-place, colored, textured and imprinted architectural concrete paving — on commercial, residential and municipal projects to create innovative spaces that complement and blend with the surrounding area.
