Soft Backer Rod: Applications and Uses

A backer rod is an important component of many construction projects. It is used in a number of applications, like flooring, stoneware, tiling, and window paneling. There are different types of backer rods but one of the most commonly used types is the soft backer rod.

What Is A Soft Backer Rod?

A soft backer rod is created from a bi-cellular, non-gassing, pliable foam material. This gives it more flexibility and a wider range of uses. A soft backer rod is often used in places that need sealing. It is a popular choice in construction applications because of how it helps sealants perform at their highest capacity, preventing sealant adhesion, and not requiring any bond breakers.

What Are Its Applications And Uses?

Due to its unique properties, a soft backer rod is used in a variety of applications, including:


  • Bridges: A soft backer rod helps with the stability and rigidity at the junction where a bridge's steel frame meets the pavement or road. This additional support assists in the development of a firm foundation.
  • Highway Pavement: Soft backer rods are also utilized during the maintenance of highway pavements. They are placed between the concrete slabs where there are some gaps and help them withstand the different loads and vibrations of passing vehicles.
  • Parking Decks: As these decks can withstand different weights, they need additional insulation or sealants to be incorporated during construction. A soft backer rod helps with the insulation and also assists with providing a strong and stable frame.
  • Wall Partitions: Soft backer rods are used to provide a cushion between wall partitions. They are used to absorb certain materials and stress, thus adding to the structural integrity of the wall.

There are more situations where a soft backer rod comes in handy. Indeed, many contractors see this humble material as an essential part of their kit. Contact Alcot Plastics today to learn more about our soft backer rods and how they can benefit your projects!
