Construction considerations Recent cost estimates of geofoam vary from $55 to $100 per cubic yard, depending on a project's required physical properties.Apr 14, 2014
Is Styrofoam the same as polystyrene?
The foam that you formerly knew as styrofoam is actually expanded polystyrene foam or EPS. This material is made from polystyrene, a plastic that's often used to make clear products like food packaging or lab equipment.
Is Geofoam sustainable?
The reason geofoam is considered a robust part of sustainability initiatives in the construction sector is due to its durable yet lightweight nature, which allows it to act as a more dependable thermal barrier that prevents the passage of inside air to the outside and vice versa.Oct 22, 2020
What is Geofoam fill?
Geofoam is expanded polystyrene (EPS) or extruded polystyrene (XPS) manufactured into large lightweight blocks. ... The primary function of geofoam is to provide a lightweight void fill below a highway, bridge approach, embankment or parking lot. EPS Geofoam minimizes settlement on underground utilities.
What is geofoam insulation?
Geofoam – Structural Insulation InsulFoam® GF (EPS Geofoam) is a lightweight, geo-synthetic fill material used as an alternative to various fill-materials, as a soil stabilizer, and in various engineered applications.
How strong is geofoam?
Despite its light weight, geofoam is remarkably strong. It can be produced with strengths up to 2,678 pounds per square foot, and as long as the combined dead/live load does not exceed one percent strain, EPS geofoam will never creep or experience plastic yield.
What is geofoam made of?
What is it made from? EPS Geofoam is made from a material called polystyrene polymer. This polystyrene resin “bead” is delivered in large containers and fed into a hopper for manufacturing. It is essentially a thermoplastic that can be shaped and reshaped repeatedly.
What is polystyrene fill?
DEFINITIONS. • Expanded Polystyrene Fill (EPS): also commonly called “geofoam”. This generic term is. used to describe expanded polystyrene formed into low-density cellular plastic blocks to be used as lightweight, stable, inert, environmentally safe fill.
What is the difference between Styrofoam and EPS?
The major difference between Styrofoam and EPS foam blocks is that Styrofoam is made from extruded polystyrene (XPS) while EPS foam blocks are made of expanded polystyrene. ... Both are polystyrene foam products made from polystyrene resins but they are manufactured into sheets and blocks very differently.Oct 21, 2019
Which is better XPS or EPS?
XPS, at about R-5 per 25 mm, has only a slightly better thermal performance than EPS. The thermal insulation performance of EPS and XPS in identical densities is quite close. However, EPS with the same level of density is less expensive.Sep 3, 2016
Can EPS foam get wet?
Foam board insulation products are generally considered water and mold resistant but expanded polystyrene foam boards (EPS) have air bubbles that can collect moisture and become wet.Jul 26, 2020
