After pouring footings, the next step is........

Yesterday we showed you a picture with concrete footings that had been built for a upcoming home here in The Champlain Valley of Chittenden County.

Today’s photograph shows you the next step in the process where the wooden “Forms” have been set in place and how the concrete is being poured into the forms.

After the footings are built the job goes this way:

  • Wooden forms are set in place, creating an 8” void that will hold the concrete.
  • The inside of the forms needs to be coated with oil so that the forms can easily be removed from the wall.
  • The two separate wooden walls are held in place using “Wall Ties.”  These wall ties are strong and prevent the forms from spreading when the void is filled with cement.  There are many types and styles of Ties.
    • In today’s photograph in the lower right corner you can see the Plywood Forms and if you look carefully you can see metal bars that are part of the Tie system.
    • After the cement is set and the forms are removed the Ties need to also be removed
  • Reinforcing steel is placed inside the forms to become a structural part of the concrete wall.  This reinforcing steel is critical, it must always be installed
  • After the concrete is poured into the forms it is important to remove all the “air-bubbles” that might be in the concrete.  These bubbles would create a void in the wall or in other words it would create a weak point.  There are several methods of getting the trapped air out of the concrete.
  • Typically, concrete is poured one day, and the forms are removed the very next day.
  • After the forms have been removed it is a good idea to get rid of that portion of the “Wall Ties” that protrude.

When all this is done the “Raw Concrete” should be allowed to air dry for about a week and then the last step is to have the wall water proofed.

All basement walls need to have footings below the frost level whether your home is in Calais or Chester.  The job needs to be done right.
