SIENASTONE SMOOTH – UNILOCK​

Bold and dramatic, this large scale wall block (smallest unit weighs 380lbs each) strikes an impressive profile when used for a heavy-duty retaining wall or as treads in large outdoor staircases. The long lines and split face of SienaStone makes it an attractive alternative to more utilitarian-looking wall blocks. Build gravity walls up to 10ft (3m) or grid reinforced walls up to 40ft (12m) high with proper engineering under typical conditions. Coping units are also available.
