Unlocking the Potential of Geofoam Insulation in Modern Construction

As demand for innovative construction solutions grows, EPS Geofoam insulation is gaining prominence. Construction professionals, including architects, engineers, site managers and contractors, are choosing Geofoam as their preferred fill material, moving away from traditional options like soil, sand, rocks, and styrofoam. 

Geofoam is a replacement for dirt and concrete, and is known for its stability, durability, efficiency, and cost-effectiveness in below grade and fill applications. During construction you'll often see white Geofoam blocks used under roadways, plaza decks, slope stabilization, bridge abatements, on and off-ramps, extensive landscaping uses and much more.

Understanding Geofoam Insulation

Geofoam insulation, also known as expanded polystyrene (EPS) insulation, is a game-changer in the construction materials industry. EPS Geofoam is remarkably light, approximately 100 times lighter than soil, and 20 to 30 times lighter than conventional lightweight fill materials. This lightweight quality makes transportation and on-site installation a breeze.

The manufacturing process is extremely eco-friendly as it involves expanding and molding polystyrene beads with steam, resulting in a strong, lightweight, and sustainable material. 

Unlike traditional fill materials that can be unpredictable, inconsistent, and sensitive to weather, Geofoam insulation offers a dependable solution without the need for complex construction installation. Compared to alternatives like foamed concrete, waste tires, soil, woodchips, and wood fiber, Geofoam stands out for its lower density, consistent composition, and long-term stability in the field.

An added benefit is that Geofoam insulation is also eco-friendly, completely recyclable, does not off-gas and is free of hydrofluorocarbons or formaldehyde. Unlike other lightweight fill, its thermal insulation properties further reduce energy consumption, resulting in a smaller carbon footprint when used below grade under buildings.

Advantages of Geofoam Insulation

Incorporating Geofoam into construction projects offers a multitude of advantages.

Perhaps the key benefits of Geofoam is its impressive weight-to-strength ratio. Unlike traditional fill materials that can exert excessive loads on the underlying soils and structures, leading to shifting and settling, Geofoam's lightweight composition significantly reduces stress. This reduction in stress lowers the risk of settlement and structural damage, ultimately enhancing the stability of foundations and extending the lifespan of the entire structure.

Other key benefits of Geofoam insulation include:

1. Versatility: Geofoam installations can be customized to meet project requirements, delivered in precut blocs and sections per job specifications, it can be installed much faster than other fill materials that require countless layers and leveling. The factory customization makes Geofoam ideal for challenging terrain, irregular slopes, and unique construction needs, to streamline projects without extensive site preparation.
   
   
2. Load-Bearing Capacity: Despite its lightweight nature, Geofoam can support heavy loads, ensuring stable support for construction projects.
   
   
3. Simple Installation: Precisely pre-manufactured Geofoam blocks ensure consistent material quality and simplified installation, reducing labor expenses and construction timelines.
   
   
4. Transportation Ease: Geofoam insulation’s lightweight composition simplifies transportation and installation, eliminating the need for complex logistics and heavy machinery costs.
   
   
5. Reduced Earthwork: Geofoam's lightweight properties also eliminate the need for extensive earthmoving equipment, streamlining the construction process.
   
   
6. Environmental Sustainability: Geofoam insulation is environmentally friendly, recyclable, and reduces the carbon footprint associated with transportation and installation.
   
   
7. Thermal Insulation: When used below grade to support structures, Geofoam insulation provides impressive thermal insulation properties to minimize temperature-related stresses and improve energy efficiency. This is especially optimal in projects requiring precise temperature control or frost protection. 
   
   
8. Warranted: R-Shield Geofoam carries a 10-year warranty, something designers and contractors will not find with other fill options such as soil and other recycled materials. This warranty enables project managers to guarantee their work. 

Applications of Geofoam Insulation

Geofoam insulation is versatile, finding applications in roadways, embankments, retaining walls, slope stabilization, and landscaping. When supporting concrete/paved applications, Geofoam reduces stress on underlying soils, mitigating the potential for subsidence and pavement deformation. This ensures roads and other similar applications last much longer than with other supporting fill material options. 

Four notable teal life examples of this are:  

1. The New Orleans Airport's use of Geofoam to help eliminate differential settlements in existing pavements during its East/West Runway Rehabilitation project.
   
2. Downtown Boston's largest highway system employed R-Shield Geofoam to alleviate stress on the underlying soil, preventing settlement under a high volume of vehicular traffic.
   
   
3. Geofoam's uniform support minimized differential settling for a large golf course and plaza deck, as seen in the installation of R-Shield Geofoam for an Atlanta Country Club plaza fill project in Georgia, which ensured a stable terrace foundation.
   
   
4. Versatility extends to landscape design, allowing intricate landscape contours and features. Landscape designers for Chicago's Massive Millennium Park used acres of Geofoam to provide a stable base for a huge park, as well to manage water drainage and reduce weight on parking structures and facilities built beneath the enormous park.
