For The Record: Plymouth Foam's EPS - Compressive Strength

FOR THE RECORD

Frequently asked questions. As an industry leader, we feel it is important to share our expertise as well as continue to educate and inform others of Plymouth Foam’s materials and capabilities.

Compressive strength is a crucial component for insulation and building materials. One of the most important mechanical property of Plymouth Foam's EPS is the resistance to compressive stresses, which increase as the density becomes higher. The compressive resistance is between 10 – 60 psi for most construction applications. Our Plymouth Foam product can be produced to meet your specific strength requirements per project needs.

PF Geofoam Spec

Standard Specification Test Methods for Plymouth Foam DuraSpec EPS are as follows:

  • ASTM C578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation: types, physical properties, and dimensions of cellular polystyrene used as thermal insulation for temperatures from -65 to 165°F. ASTM C578 covers types of EPS thermal insulation currently available and the minimum requirements for the properties considered most important.
  • ASTM C203, Test Method for Breaking Load and Flexural Properties of block-type thermal Insulation; flexural strength and compressive resistance values are included.
  • C165, Test Method for Measuring Compressive Properties of Thermal Insulations and/or
  • D1621 for Test Method for Compressive Properties of Rigid Cellular Plastics.
To meet the compressive resistance requirements specified in ASTM C578, polystyrene thermal insulation boards must provide the following compressive strengths at 10% deformation when tested in accordance with ASTM D 1621.

The EPS Industry Alliance shares Plymouth Foam DuraSpec EPS high resiliency and strength characteristics, expanded polystyrene insulation offers:
  • Absorption of substrate and facing movement caused by temperature changes and structural deflections
  • Absorption of substrate irregularities
  • Thickness recovery following excessive construction load exposures
  • Suitable subgrade reaction for effective load distribution
In conclusion, the structural strength of Plymouth Foam DuraSpec EPS is crucial for every project. We take pride in our work and customer satisfaction from start to finish and after.

GeoFoam Green Roofs: Growing Growing Growing


Green Roofs continue to grow in popularity, especially in large urban areas. These areas can suffer from the “Heat Island Effect” which is caused by black roofs, black asphalt parking lots, concrete and lack of green space. Green roofs, also known as “living roofs” or “vegetated roofs” use plants to lower roof temperatures and create a biodiversity ecosystem encouraging additional habitats of plants and animals.

Geofoam - Green Roofs

Plymouth Foam has been involved in numerous green roof projects and have noticed that Engineered DuraFill EPS (GeoFoam) has turned out to be the best solution. Here are the reasons we discovered:

Green Roof

Plymouth Foam’s DuraFill Green Roof Products can help reduce cost by combining several products into one combination product reducing labor installation costs. Where most systems have insulation above the waterproofing membrane exposed to moisture, DuraFill can be engineered to move water more efficiently to the drains. DuraFill EPS can be designed to have predictable compression for walkways, loads and foot traffic.

Using your roof to create garden or outdoor living space can greatly reduce your heating and cooling costs. It can also help to reduce the Heat Island Effect.

A properly designed Geofoam Green Roof can increase the life span of the roofing system by
improving water flow, reducing ultraviolet exposure to the roof membrane and reducing insulation below the waterproofing membrane which lowers thermal roof stress.

Swimming Pool Geofoam Project -not too deep to revitalize

Pool 1

The Ashwaubenon Community and School District faced a dilemma - what do you do with an indoor pool that is over 48 years old and has outlived its expected life? Think “outside of the pool” and fill it in with Plymouth Foam’s Durafill GeoFoam and give new life to the building!

Restoring this aged pool was not a viable option as there were too few of lanes and replacement parts were no longer available. The community decided to build a new pool, but what do you do with the old one?

The building that housed the pool was still in good condition. Filling it in with Engineered EPS Foam and pouring 5” of concrete on top “gives this building a new purpose.” This new area will be used as a commons area with tables and chairs for students to eat lunch.

Like all schools districts, needs change. Filling the pool in with foam has a number of possibilities for the district. Foam can be removed and the area can be repurposed for maybe stadium seating or a performance stage. The possibilities are endless.

Pool 2

Filling in a pool sound easy, but reducing in-fill weights and loading pressures of traditional fills such as gravel or stone can be impractical or unachievable. Geofoam to the resue, however filling in a pool with different depths and various slopes is not an easy task.

Boldt Construction’s design team working together with Plymouth Foam Geofoam Consultant, John Calkins, and was able to offer DuraFill Geofoam blocks that were manufactured in various sizes to fit to the contour of the pool. The pieces were labeled and shop drawings were used to install the pieces. Boldt Construction was the general contractor and they “did an excellant job of making the pieces work and come together.”

Using a local contractor and a local manufacturer has many benefits for the local ecomony. Tax money collected for the school district is being spent locally and benefits from the “local multiplier effect.” This multiplier means the money is recirculated 3-5 times in the local economy and is a key tool for creating more local jobs. The school district saved money on transportation cost since the manufacturing facility is less than 75 miles away - now that is “thinking outside the pool.”

Local College ramps up savings and cuts build time

Wisconsin Lutheran College located, at 88th and Bluemound, in Milwaukee, WI is one of the fastest growing and most affordable college in Wisconsin. With the student body increasing, the need for additional parking was greatly desired.

Wisconsin Lutheran College is nestled between a beautiful Wauwatosa neighborhood and a busy Freodtert Hospital Campus. Designing and building a structure for parking needed to fit into the community and yet be functional. The end result was mentioned by a local official, “this may be one of the most beautiful parking structures in the county.”

Designed by HGA Architure and Engineering, this state of the art, 4 level Parking Center has the ability to hold 350 vehicles. Security and safety was built into the project for the users with an abundance of lighting and a security station. Another great feature to this parking center is the access in is very spacious and it has a two lane exit point for left or right turn functionality. The feedback from students on the additional needed parking has been extremely positive.

One of the real construction challenges in building this Parking Center was the problematic soil conditions that place extremely high lateral loads to the foundation walls. Designing and specifying regular fill material to help these lateral load conditions would take settling and compression time. This extends the project build time and increases cost.

Another challenge to the project was the confined area that was sloping toward the project. Moving heavy equipment and material into the site took careful planning. Weather and construction conditions were managed by a great team of construction professionals from Catalyst Construction.

Plymouth Foam’s DuraFill Geofoam was able to meet the challenge of this project by reducing the construction time line by providing a “ready to build site.” Reducing the build time reduces labor costs and carrying loan cost for the college. Staying on time and on budget for a large construction isparamount in the construction world and DuraFill delivered.

Other fill materials are seldom controlled and can produce varying effects and outcomes. Plymouth Foam’s DuraFill Geofoam is controlled during the manufacturing process and is designed and engineered to accomplish those specific construction outcomes. DuraFill meets the challenge of being an ultra-lightweight material that can reduce load settlement and improve stability against bearing and slope failures.
