After the footer is poured...

...the workers use this rotating laser level to make sure all the parts of it are even with each other.

Masons begin laying cement block on top of the concrete footer around the steel reinforcement rods.

Here, two workers are using laser guides to make sure the wall will be straight.

The hollow spaces within the blocks are filled with concrete.

The four short orange-capped bolts at the corner will hold down the steel corner post.

Gravel is used to fill the empty space on both sides of the foundation wall.

This black paint will seal the wall and keep water from leak into the mortar and block.
