Erection Guidelines

• • • • 0,9m to 3m Lintels: Minimum bearing of 200mm on each side and four courses of bricks
      • 3m to 4,2m Lintels: Minimum bearing of 250mm on each side and five courses of bricks. Temporarily support in centre for approximately seven days.
      • 4,5m to 6m Lintels – Standard method: Minimum bearing of 300mm on either side and six courses of bricks. Temporarily support for approximately ten days.
      • 4,5m to 6m Lintels – Cavcon recommended method: Lay Lintels upright, that is on their narrow side, to greatly increase their moment of resistance. Use 3 lintels side by side if necessary. Minimum bearing of 200mm on each side and five courses of bricks. Highly recommended to install temporarily support for approximately ten days.
