The ring-block, known in the U.S. as the lintel-block was first introduced in 2002. Before ATCO could market this product, however, we had to acquire permission at the Aruban Public Works due to the fact that a bond beam is a calculated structural part of a construction. As it has been custom for many years to place forms and pour concrete to form a bend beam. It was not the easiest task to convince the locals to do otherwise. However, persistence and confidence in the product demonstrated its value. By using ring-blocks as a replacement of forms you could save approximately 40% of the cost of a completed bond beam as well as saving a few days time.
