"York Building Products provided a big block MagnumStone gravity retaining wall for the Rollins Property project (Amazon Data Center) in South Riding, VA. The wall was built in 2021 by Roche Brothers (wall builder) for their client The Anderson Company (site contractor) who worked for Hitt Contracting (general contractor). 8,372 SF of wall area was installed and the wall is 676' long with a maximum total wall height of 19'. MagnumStone concrete extenders were used to increase the base depth up to a maximum of 10' on the tallest section (2' block + 4' extender + 4' extender). Earth Retention of Leesburg, VA did the wall design and a portion of the wall required geogrid reinforcing behind it to accommodate the load of a crane which was used to construct the building afterwards. MagnumStone's ability to increase the wall depth by 2' increments with the use of 2' long and 4' long concrete extenders was key in making this wall cost effective and easy to construct."
