I am a homeowner and I just built my first wall in the front of my house. It is built out of Mesa Blocks which are basically concrete block with decorative front. The wall is 24 ft long and 3 foot deep. Each block weighs approx. 75-80 lbs. The wall is 3 blocks high or 36" with 4" caps. The wall sits out about 3 feet from the front of my house and the property is mostly level with the bottom bricks totally buried for about 15 foot of the wall. About 5 of the bottom bricks are totally exposed due to the grade of the land. I did not use item 4 or sand or any sort of crushed stone for a footing. I just dug down in the dirt and to set the bottom stone. I went crazy making sure everything was level. I am worried that as the ground settles the blocks will start to move. I live in the Northeast and the ground is pretty much compacted soil. I have not backfilled the wall yet. It has been up for approx. 1 month and I have not noticed any settling. Should I tear down the wall now and rebuild it using a real footing? Since it is up for approx. 1 month has it already settled? We got a lot of rain in the last month so I would think if anything were to happened it would have happened already. I plan to backfill the entire wall with topsoil and plant trees/shrubs and some other plants.
