Level Three - Master Wall Builder

The third and final step in the program is Level Three, the Master Wall Builder. Contractors that reach this level have both the knowledge and the skills to build top quality Allan Block walls.

  • Detailed project proposals were submitted and pre-  construction meetings were held for each wall
  • All walls built have a minimum height of 3 ft (0.9 m)    and a minimum of 300 units (full size or equivalent).

  • Material lien waivers were supplied to the property owner and/or general contractor at completion of construction for each wall

Notify your local Allan Block sales representative of any AB walls you would like submitted toward your Level 3 Master Wall Builder certification so that your local sales representative can submit the appropriate paperwork to Allan Block Corp
