A hollow block measuring 2′ x 4′ x 3′, Verti-Block™ is perfectly proportioned for the most popular types of landscaping projects, including gravity walls up to 14′ high – even higher when reinforced. It’s hollow design makes it affordable and easier to handle than solid blocks. Plus, Verti-Block™ is less labor intensive than small, hand laid blocks and offers a more practical solution than a cast-in-place wall.
