How to Make a Concrete Tabletop and Base

This two-part table is made using CHENG D-FRC. The top is easy to form up using CHENG Curved Wall Sections, while the base is cast in a more advanced foam with epoxy coating form.

One: Table Base Forming

The base form was initially modeled in a vector format before processing in CAD to CAM software and ultimately shaped from EPS foam by a CNC router.

Two: Table Base Spraying

Each half of the form is initially cast separately to allow efficient placement of the fiber reinforced concrete mix before the forms  are seamed together.

Three: Table Base Casting

Glass fiber scrim and fiber reinforced concrete backer mix is used to “stitch” the two halves of the table base form while the concrete is still pliable.

Four: Tabletop Forming

3/4″ melamine and EPS foam are used to shape this 48″ diameter table top. The table also has a hole in the middle to accommodate a large table umbrella.

Five: Tabletop Casting

A flowable fiber reinforced concrete mix is initially sprayed into the form before a stiffer backing mix is placed as structural reinforcement.
