Geofoam Insulation

Engineered EPS to Lighten the Load

GEOFOAM - The Poor Soil Substitute

Best Geotechnical Solution

Expanded Polystyrene (EPS) rigid insulation is the most cost effective and by far the best value for most Geofoam applications. Engineered Geofoam EPS is lightweight, durable and very versatile. In fact, Plymouth Foam’s DuraFill EPS Geofoam Insulation can be formulated to provide a wide range of engineering properties for most projects needs. Geofoam can be used for a variety of application.

Geofoam Advantage

Lighten the Load

Geofoam can be up to 100 times lighter than soil and 50 times lighter than traditional fills with similar compressive strength. Geofoam has the ability to reduce mass and connected gravitation physical forces. This super lightweight fill material can help reduce soft soil loads. Its weight-to-strength load bearing characteristics are uniquely effective in reducing the weight burden on underlying soil without sacrificing compressive strength. Plymouth Foam DuraFill EPS Geofoam weight is between .75 lbs/cubic foot - 3.o bs/cubic foot.

See how weight was reduced using Durafill Geofoam on a resort project on a Lake Michigan peninsula.

Reduce Construction Timeline and Labor

Site conditions such as weather, poor access, and/or harsh terrain can add cost to a project by creating longer build timelines as well as job delays. Geofoam may not be as materially as cheap as dirt or some other fills, but it is most often quicker to install and easier to move. This speed and ease of Geofoam can reduce labor cost and reduce equipment moving cost which makes a project less expensive overall.

There are numerous ways that Geofoam can reduce cost:

Geofoam does not have to be compacted
Compared to other fills Geofoam can be placed quickly without the use of large equipment
Delivery costs are reduced as 1 truck of Geofoam equates to 12 truck of other fills
Not expensive or time consuming form needed as Geofoam can have materials used direct on or next to it
Many case less material to be removed in using Geofoam
Possibly reduce the amount or thickness of concrete used
Less expensive structural utility products could be used with less loading
Less settlement can decrease call backs or maintenance costs

See how the Chicago Museum of Science and Industry used DuraFill Geofoam for their submarine exhibit and reduced construction costs.

Enviromentally Friendly

EPS is environmentally friendly in so many ways. EPS consist of 98% air and the 2% that remains is derived from a by-product of oil refining. By-products that could become waste, but have found there way into a productive product that saves energy. In fact, EPS insulation can return up to 200 times the amount of energy required to produce it, and reduce emissions by up to 100 times the volume produced during the manufacturing process. EPS is one of those product that can be used and recycled over and over again. Learn More

Additional Geofoam Advantages

Predictable Uniform Material BehaviorGeofoam can be designed and manufactured to attain and maintain a more specific design criteria which is quite different from alternative fill products that can fluctuate and become unreliable.
Lateral Pressure ReductionGeofoam is light weight and can reduce the lateral force on a retaining wall or abutment.
Thermal Insulation PropertiesGeofoam l is 98-99% air by volume, making it a highly efficient thermal insulator. It can be used to thermally protect utilities or other frost prevention application.
Non-BiodegradableOur Geofoam will not lose it physical properties or degrade while covered, thus assuring a long life and long-term performance.
Inert - no leachingOur Geofoam has no leaches and will not contaminate the surrounding environment.
Low interface friction
In direct shear tests the interface friction between sand and our Geofoam is comparable to the internal friction of sand alone.

Tapered EPS insulation comes in a large variety of profile thickness, pitches and densities. Each project can be custom manufactured to fit your customized tapered roof layout. Plymouth Foam’s customization provides many advantage to make the job better and provide better value.

Geofoam Application and Uses

Plymouth Foam manufactures Geofoam insulation for the United Sates including the states of Wisconsin, Illinois, Indiana, Iowa, Minnesota, Michigan and Ohio. Plymouth Foam provides Geofoam insulation using Expanded Polystyrene (EPS) in the form of flat insulation, tapered insulation and block insulation. Durafill EPS Geofoam is a lightweight closed cell rigid foam insulation used in a wide variety of geotechnical applications. Geofoam can be used for road embankments, retaining walls, abutment backfill, slope stabilization, pavement insulation, roadway sound barriers, foundation fill plaza decks, levees, dikes, landscaping berms, utility protection, frost protection, stadium seating, foundations, green roofs, cold storage, construction fills, tunnels, pool infils and decks, garden decks, and even recreation forms such as mini-golf, obstacle courses, racing and ice rinks. Geofoam is an engineered light weight fill designed to reduce loading. Plymouth Foam’s EPS, the safe insulation, is manufactured in Wisconsin, Minnesota and Ohio.
