Geoquest’s post-and-panel sound wall system takes an innovative approach to a common solution. The wall consists of drilled caissons with prefabricated concrete posts and panels. The posts are structurally secured to the top of the caissons via a unique connection utilizing corrugated metal cannisters filled with structural grout. The precast posts are temporarily supported by means of post-tensioning, which eliminates the need for external bracing, and allows for alignment adjustments. The segmental stacked panels are set between the posts in a fashion common for post-and-panel construction.
