SYSTEM CAPABILITY

What the system can do and what one completed object did are different quantities, so they stay in separate columns.

Maximum wall batter (vertical to horizontal) is site specific and subject to design conditions including loads, geometry, soil characteristics, reinforcement selection, and governing codes. Engineering evaluation required.

Wall height, reinforcement length and spacing, drainage detailing and foundation requirements are determined by project-specific design.
