Update on NRV Passenger Rail Project
In Christiansburg, contractors have substantially completed the sub-structure of the parking lot. The T-Wall, or Gravix Wall, is a heavy-duty concrete wall used to hold back the earth. Cellular concrete, lightweight concrete filled with tiny air bubbles, will be poured into the empty spaces between the “T-Stems” which make up the structure of the T-Wall. The T-Wall will create a strong, level base for the parking lot at the correct grade elevation.
