Concrete Porch Floors

Mystery Solved - We Show You How They Do It

Mary and I had the opportunity to document how a concrete porch floor, concrete steps, and walkway are constructed. It is easy to take for granted the materials, processes, and labor that go into these structures and we want to show you how it's done.

You may be surprised how much effort goes into constructing these essential elements of a home.


We start with a bricked porch facade and porch roof on a two story home which has already been constructed. The concrete floor covering for the front porch will be approximately 8 feet above the ground. Because this is new construction, a walkway from the driveway to the porch steps will also be framed and poured.

Aggregate Concrete Porch Floor Construction Process

This is a particularly high bricked front porch. The brick facade actually covers a concrete block foundation which is easily seen in the photo below.

Because of its height, a subfloor needs to be constructed to hold the concrete porch floor. Filling the porch cavity with stone or concrete block might be an option but it would take consider fill to raise the porch floor to the appropriate level.



The first step is to chip out the brick above the foundation blocks to create holes into which steel channels will be inserted. As you might imagine it took considerable time to create the holes for the steel channels.

Steel channels will support the corrugated metal sheathing onto which the concrete flooring will be poured.

The steel channels are inserted into the slots and spaced approximately 12 to 16 inches apart.

Once they are in position on top of the concrete block foundation, the steel sheathing is placed on top of the channels.

Approximately four to six inches of concrete is then poured over the sheathing. A concrete pumping truck was used to help pour the concrete due to both the height of the porch and the distance from the street. The pumping truck operator uses a remote control to guide the concrete hose which has a reach of over 100 feet.

Once the concrete is poured it is sprayed with a surface retarder (see box below) and then is covered in plastic to help the curing process. Since this is going to be an aggregate porch floor the plastic will be removed in a short time and pressure washed to expose the aggregate stone.

How Do They Create the Concrete Aggregate Look?

rugasol surface retarder In order to create an aggregate appearance the top layer of concrete is washed away to expose the stones within the concrete.

A concrete surface retarder is used to stop the setting of the top concrete layer without interfering with the hardening of the concrete below the surface.

Rugasol, like that shown here, is a common concrete retarder used on many concrete porches and driveways to produce the aggregate appearance.





When the concrete has cured, you have a beautiful aggregate concrete floor covering.
