Once the Stem wall is built, rebar installed, and Integra bolts layed out, it is time for it to be inspected, and grouted.
On larger jobs, a concrete truck and a grout pump is used to fill up the block wall. Most stem walls are grouted completely solid. You can see in the photo below , a concrete truck, the grout pump, and the hose leading to Jason and Aaron while they place the “grout”. (Grout is concrete that has smaller rocks in it so it will pass through the hose and flow properly inside the wall)
Once the grout is placed, the grout is scraped level to the block, and the integra bolts are placed into the grout according to a plan outlined by the Integra Engineers.
Once the stem wall is complete, it is time for the plumbers and electricians to place their “underslab” piping in its position. Then the stem wall is back filled with dirt, and compacted, a layer of ABC (rock and sand) is placed on top of that leaving about 4″ remaining for the concrete floor to be poured to the top of the stem wall.
Here is an example of what can happen when you burn wood in a fireplace that was designed for gas. The Homeowner burned wood in his fireplace for a while, and then decided to switch back to gas. He neglected to clean out the ashes that had piled up over the burner. When he turned on the gas, it built up under the ashes and exploded when he tried to light it. This fireplace was not built properly and could not withstand the explosion. The insurance company called us to rebuild and repair it because they knew it would be done right!
This outdoor fireplace was constructed without rebar (reinforcing rods) and grout (concrete) in any of the open cells in the walls. The result was a destroyed fireplace,and a seriously injured homeowner. There would have been considerably less damage to the fireplace had it been constructed properly. As it was, the homeowner was lucky to be alive after being knocked unconscious and blown into the swimming pool with 100 lb. chunks of the fireplace found up to 50 feet away. Luckily for him, his wife was inside the house, heard the explosion, and decided to investigate.
