What is InsulFoam®

GF?

• A closed-cell expanded

polystyrene (EPS)

• A lightweight, engineered, soil-

replacement fill

• Commonly referred to as

Geofoam

• An economical and

environmental alternative to

other fill materials such as soil,

shredded tires, waste, cellular

concrete, wood chips, pumice,

basalt and porcelain chips Crescent, CA – Slope Stabilization

5 MAJOR APPLICATIONS

TO CONSIDER GEOFOAM

RETAINING STRUCTURES

Eliminate or Reduce Lateral Loads for

• InsulFoam GF replaces thesliding soil wedge

• Native soils are self supportingwhen excavated back to the angle of repose

• InsulFoam GF is self supporting

• End result: ZERO lateral loadon the retaining structure

InsulFoam®

GF Benefits

• Significantly reduces

structural steel, concrete and

forming costs/time

• Decreases or Eliminates the

need for geo-grids or

mechanical tie-backs

• Allows walls to be designed

taller and in more narrow

rights-of-way

• Eliminates the need for

secondary compaction which

speeds construction

SOFT SOIL REMEDIATION

Net Zero Load Designs for

• Soft soils only settle whenmore weight is added on top

• Calculate the weight of theGeofoam and all other loads

• Excavate an equivalent weightof native soil

• End Result: Net ZERO loadingI-680 Interchange – Martinez, CA

SLOPE STABILIZATION

Lighten the driving block for

• Heavy Soils + Gravity + H2O

= High Landslide Potential

• Geofoam is up to 100 times

lighter than soil

• Using Geofoam reduces

the weight and the risk

STRUCTURAL VOID FILL

CONCRETE APPLICATIONS

Keep it Simple and Fast with

• Eliminates separate concrete

pours for vertical wall sections

• Reduces overall amount of

concrete or other heavy fills

•Reduces dead loads on

underlying structures

•Any shape or slope can be

easily fabricated on site

GF Benefits

as a Structural Lightweight Void Fill

• Eliminates the need to

pour the walls separately

from the topping slab

• Decreases labor costs

versus heavy soil backfill

• Decreases forming time

and material costs

• Easily supports the

weight of concrete slabsCommunity College, Scottsdale, AZ

BURIED UTILITY PROTECTION

Protect and lighten the load on top of

• Reduces dead and lateral

loads on underground pipes,

culverts and tunnels

• Protects utility during seismic

activity by reducing axial strain

•Provides high thermal

insulation values that protect

against severe temperature

fluctuations

Seismic Protection

• Protects utility

during earthquakes

– Allows for utility

movement

without inducing

large bending

stresses

• Allows construction directly

on top of buried utilities

• Eliminates right-of-way or

eminent domain claims to

move the utility

• Allows designers to specify

less expensive structural

utilities such as box culverts

and pipes

• Reduced dead loads

prolongs the life of structure
