Wagman Heavy Civil, Inc. and Wagman’s Geotechnical Construction group provided all necessary equipment, tools and personnel for the construction of a retaining wall in Chapel Hill, NC to protect a neighborhood from a slope failure.
Utilizing the Bayshore Systems LD 60, Wagman drilled 110 shafts at 30” diameter. Wagman then placed and aligned the soldier piles. In coordination with Wagman’s heavy highway crews, the shafts were poured and the wall panels were placed. The new retaining wall ensured the safety of the residents.
