The "bending" or "warping" of concrete is a technique that we've found can be done successfully with glass fiber reinforced concrete (GFRC) and rubber molds. GFRC is cast into a flat rubber mold and then the mold is re-positioned during a point in the concrete's cure cycle where the concrete can be manipulated without sagging.
The resulting concrete décor can be used for a variety of purposes, including tables, planters, light housing, garden décor or garden trellis, artwork, decorative panels (when cast flat), and much more.
Take a look at two tutorials below featuring these techniques:
Tutorial: Casting “Warped” Concrete Tables in Rubber Molds
This video tutorial details the process of casting side-by-side “warped” concrete tables in a Polytek® Poly 74-45 polyurethane rubber mold. The original model was constructed from MDF and coated in a primer paint and the mold is made with Poly 74-45 liquid rubber, a mid-range hardness, two-part polyurethane rubber.
Tutorial: How to Bend or Warp Decorative Concrete in Rubber Molds
This video tutorial details the process of casting warped decorative concrete elements in rubber molds made from our liquid mold rubber. The original model was constructed through a series of steps involving wood, silicone rubber, and polyurethane casting resin.
