Building a Cinder Block Foundation for a Molble Home:

When building a cinder block foundation for your mobile home weather it is already set up or you are building it before you set your mobile home. Here are a few steps to help accomplish the job.

Laying out the foundation:

  1. You will need to measure the area where you plan to build the cinder block foundation and mark the corners with stakes. This will help you determine the size of the foundation you need to build, as well as ensure that it is properly aligned with the mobile home. You’ll need a tape measure and some wooden stakes for this step.

Excavating for the foudation:

2. Excavate the area for the cinder blocks to a depth of about 6 inches and remove any vegetation or debris. Use a shovel or a mini excavator to dig a shallow trench around the perimeter of the foundation area. Make sure to remove any roots, rocks, or other debris that you encounter as you dig.

Leveling and Compacting:

3. Level the ground and compact it with a plate compactor. Use a long level or a laser level to ensure that the ground is even, and then use a plate compactor to tamp down the soil. This will help to create a solid base for the foundation.

Adding Gravel:

4. Install a layer of compacted gravel to act as a base for the foundation. Spread a layer of gravel over the compacted soil, and then use the plate compactor to tamp it down until it is flat and even.

Placing the Cinder Block:

5. Place the first course of cinder blocks on top of the gravel, using a level to ensure that they are level and aligned. Arrange the blocks in a straight line, making sure to leave enough space between them for the concrete that will be used to fill the gaps. Use a level to ensure that the blocks are level and aligned with one another.

Continue building the foundation with additional courses of cinder blocks, using a level to ensure that each course is level and aligned with the previous one. As you work, make sure to leave enough space between the blocks for the concrete.


Use concrete to fill in the gaps between the cinder blocks, making sure to smooth it out so that it is level with the tops of the blocks. Use a trowel to smooth the concrete and create a sloping slope from the top of the blocks to the ground, which will help to direct water away from the foundation.

Allow the concrete to cure for a few days before proceeding with the next steps of your mobile home installation. This will give the concrete time to harden and reach its full strength.
