A Masonry Wall and Slide Repair Using Soil Nails and Rock Dowels

In August 2003 Vermont experienced several days of very heavy rains which precipitated a slide failure on Vermont Route 73 in Forest Dale. A blocked culvert on the south side of VT 73 caused an overflow of water across the road surface and over an asphalt and wood curb down an embankment. This resulted in a significant amount of erosion, undermining of the road surface and a washout of a timber cribbing retaining structure located on the top of a mortared masonry wall. Site visits determined that the laid up masonry wall immediately west of the slide area was also in desperate need of repair. This article discusses the design and construction of the needed repairs.
