Dura-Hold is a great alternative to poured in place retaining walls. Its large scale (standard size weighs 1,680lbs) is disguised by false joints which cast bold shadows to give the appearance of several individual blocks in each unit. Build gravity walls up to 6ft (1.8m) or grid reinforced walls up to 40ft (12m) high with proper engineering under typical conditions. Concrete tie-backs or Geogrid give this wall various engineering options. Coping units are also available.
