Portsmouth High School Retaining Wall Case Studies
Situation: Portsmouth High School was building a new facility and the new footer was
being installed within 2 feet of an existing retaining wall that supported
an elevated parking lot. The wall was compromised by water intrusion and
poor soils. The first week on the project the temperature was 3 below
zero with a wind chill factor of 15 below. As the temperatures rose, so
did the swamp-like working conditions.
Solution: A local engineering firm working with the general contractor, Solid Rock
Construction, specified helicals as a method of repair. We installed 76
2-7/8” helicals at an average of 70 feet per pier. Then whalers
where installed to support the steel post of the retaining wall.
Conclusion: Ram Jack’s durable powder coated piers are perfect for installation
in swamp-like conditions. Working together we were able to secure the
wall and provide a safe working area for the builders.
