Standard Installations
The latest in proper bedding and backfill of reinforced concrete pipe. The new four types of installations replace the old Marston Spangler Class B,C &D beddings that have been used since the 1920's. The Standard Installations have national approval by ASCE and AASHTO. Emphasis is placed on the versatility of the different bedding types, to allow deep burials of concrete pipe, as well as specifying different types to suit jobsite soil conditions.
Knowledge of the Standard Installations is necessary to run the 3EB software.
