Kenmore Retaining Wall

Here we had a dry stack block retaining wall that was improperly constructed at the bottom of a 150’ tall & very steep hillside.  We stabilized the existing retaining wall with 2” pin piles and helical tieback anchors so we could safely build a new shotcrete wall in front.  Once the new structural wall was in place, masons came in and faced the wall with an architectural stone. Helical Anchors provided by Helical Supply LLC.
