How to Build a Column Mail Box

A column mail box can add curb appeal to any home or business. It's a project that you can do on your own, but requires some concentration and time, according to Pyzique Wall Systems. A column mail box is made of concrete, and for this reason, is sturdier than a stand alone plastic or metal mail box. If you decide to build your own column mail box, take into consideration that it is a permanent fixture.

Things You'll Need

• 3-12 x 16 x 14 cap blocks
• Square concrete blocks
• 12" x 16" x 14" concrete blocks
• Measuring tape
• Shovel
• Concrete
• 6 rebars
• Mortar
• Wall ties
• Standard plastic or metal mail box
• Level
• Framing squares
• Pencil

Instructions

1. Measure a hole that's 42 inches-by-42-inches where you want your mailbox. Dig a hole that's 12-inches deep.

2. Mix cement by following the manufacturers directions. Fill hole with one-third of your cement mixture.

3. Place six rebars criss-cross of one another, leaving a three inch space between each bar. Pour one-third of cement on top and allow it to dry.

4. Place a level on top of the dried cement facing up. If cement is uneven, add more concrete until level.

5. Place one cement block on top of the cement. It's recommended you place the long side of the block towards the street, according Keystone Retaining Wall Systems, Inc..

6. Cover cement block with a thin layer of mortar.

7. Put wall ties in mortar at each corner of the cement block. This will help support the column mail box, according to Keystone Retaining Wall Systems, Inc.

8. Lay blocks on top of one another, adding a layer of mortar in between each block. Continue adding concrete blocks until the wall is about four inches tall.

9. Set a 12 x 16 x 14 cap block on top of your column. According to Keystone Retaining Wall Systems, Inc, you will place your metal or plastic mail box on top of this.

10. Let mortar dry for 12 hours.

11. Put mail box in middle of cap block.

12. Arrange concrete bricks around mailbox. Fill in any holes with mortar.

13. Put two 12 x 16 x 14 cap blocks on top of mail box. Allow mortar to dry for another 12 hours.
