Proto II's retaining wall system is a winning blend of efficiency and strength that results in tremendous benefits for the builder:

• Eliminates rebar, solid grout, and grout inspections.
• Eliminates jurisdictional inspections.
• Efficient footings - option of continuous trence, post and beam, or spread.
• Continuous trench footing accomodates property line conditions.
• Minimal backcuts required for trench footing.
• Eliminates cure time for grout, allows backfilling immediately after full tensioning of rods.
• Mortarless head joint, tongue and groove units may be used, increasing productivity.
• Proto II™ post tension retainer uses 8-inch cmu (standard C 90 specification), many times in lieu of 12-inch conventional.
• Utilizes same hardware as used in the Proto II™ Fence Wall.
