Precast

Graphite Polystyrene (GPS) is an advanced foam material ideal for precast and cast-in-place concrete applications where high thermal resistance and compressive strength are required. Lighter than traditional materials and offering a higher R-value per inch, GPS helps simplify concrete forming, improve thermal performance, and reduce structural loads.

Our GPS foam is custom-cut to your project’s specs, making it easy to create complex shapes and repeatable forms. It’s commonly used as void fill, blockouts, and cores in everything from structural panels to detailed architectural designs.

Details & Uses

Common GPS Precast Uses

  • Bridge barricades and barriers

  • Architectural reveals and decorative features

  • Panel voids and wall insets

  • Manholes and vault forms

  • Cast-in-place wall sections and blockouts

Why Use GPS for Precast?

  • Lightweight and easy to install

  • Enhanced compressive strength for demanding environments

  • Provides insulation for sandwich panels or embedded features

  • Precision-cut for repeatable, complex shapes

  • Moisture-resistant and dimensionally stable

  • Higher thermal efficiency than standard EPS

Our Foam Products

Foam questions?

We've got answers.

Learn more about the applications for our foam products.

Our specialties are expanded polystyrene (EPS), expanded polypropylene (EPP), and graphite polystyrene (GPS), These products have many applications, and can be used in roofing, insulation, landscaping, stabilization, exterior siding, and more.

We do have the capability to customize our products to your specific needs. In addition, we offer custom packaging, either to ensure your product arrives damage-free, or for your own shipping and packaging needs. 

Most of our applications can be made with multiple foam types, and we’ll guide you to choose the best one for your requirements. Here’s a list of what we manufacture: 

  • Custom packaging: EPS or EPP
  • Insulated shipping containers: EPS or GPS
  • Precast: EPS or GPS
  • Garage doors and door cores: EPP, EPS, or GPS
  • Sheathing: EPS or GPS
  • EIFS: EPS or GPS
  • Geofoam: EPS
  • Roofing: EPS
  • OEM: EPP, EPS, or GPS

If multiple foam types are able to be used in your project, we’ll discuss the benefits of each product and decide together what will be the best choice for your project. 

Many of our products can contribute to LEED points, depending on application and use.
