Increasing Gravity Wall Heights
At times a gravity wall may need to be slightly taller than the maximum allowed for the given site conditions. One way to increase the maximum allowed height of a gravity wall is to increase the wall batter, thereby reducing the stresses placed on the wall. ReCon has developed a one-inch fiberglass spacer bar that increases the effective batter of a Series 50 wall to 7.2°. These spacers are placed behind the tongue of a Series 50 unit while the wall is being built. When the next course is laid the spacer bar limits (by one inch) how far forward the unit can be slid forward to make positive contact. The following gravity wall height charts demonstrate the effect of building a wall, or section of wall, using the spacer bars.
