Geofoam is used as backfill behind retaining walls to greatly reduce lateral pressures. Placement of geofoam behind retaining structures and below-grade walls can offer advantages of reduced lateral pressure lower settlements improved water proofing and better insulationThe central concept in using geofoam as a retaining structure backfill is to substitute as much of the soil in the active or at rest wedge with geofoam to the extent desired.

Geofoam For Swimming Pool Construction Geofoam Styrofoam Eps Polystyrene Universal Foam Products

Solutions for lateral earth pressures on.

. Traditional retaining wall design has always focused on reinforcement of the structure to resist the powerful lateral load factors that are exerted by extrem. Its durability and exceptional. Im not sure Id want to use shotcrete on the foam per the article you linked to DAVIDGF.

The interaction between the geofoam blocks and the backfills is essential for the determination of the earth pressure and thus the design of the geofoam blocks. Retaining Walls using EPS Geofoam Sayed M. Unibloc Geofoam is a high performing fill material made from EPS Expanded Polystyrene designed and engineered specifically for civil and commercial building construction around Melbourne.

When used properly behind a retaining wall is reduces or completely eliminates lateral pressure on the wall. Investigations on the properties of EPS geofoam and the related design problems have also been carried out 1-24. However research to determine the lateral earth pressure on retaining walls with geofoam inclusions is limited.

I feel like I need to design to some nominal level of load from the foam if it is set directly adjacent to a covering precast panel set foam set panel infill with pea gravel between for instance. EPS geofoam design loads are recommended to not exceed the compressive resistance at 1 capacity. The lower weight of geofoam allows construction workers to easily construct segmental retaining.

EPS geofoam has been used in road and airfield pavements and railway track systems beneath refrigerated storage buildings sports. Adequate soil cover or a load distribution slab may be needed to distribute heavy concentrated loads. Belal Abstract Due to backfilling and surcharge pressures from the foundations of adjacent buildings retaining walls are built to withstand the ground pressure and lateral thrust.

According to Wikipedia a retaining wall is defined as structures designed to restrain soil to a slope that it would not naturally keep to typically a steep near-vertical or vertical slope. EPS on the reduction of lateral earth pressures was discussed aiming to form a comprehensive reference for calibrating design methods of the nonyielding retaining walls with EPS geofoam. Geofoam is used to replace heavy fill materials to reduce settlement.

Expanded low stiffness polystyrene EPS geofoam panels mounted vertically against. EPS has a density that is less than 1 of typical soil fills. It offers special advantages for construction on soft ground slope stabilization and retaining walls.

In this study two-dimensional model tests of aluminum rod. 96 Fourth Avenue Haskell NJ 07420 800229-7161. The EPS15 geofoam was delivered in 10 precut blocks ranging form 8 x 12 x 48 to 8 x 30.

Unlike other materials used for retaining walls geofoam does not rot decompose or leak down into the ground as time progresses. GeoFoam - lateral pressure on walls GeofoamSpecialist Geotechnical 9 Apr. It is used in highway bridge and retaining wall projects because of its light weight stability strength and ease of installation.

This limit controls the amount of long-term deflection or creep resulting from permanent ustained loads. Horvath 5 describes the concept of EPS geofoam compressible inclusions to attenuate earthquake induced forces against rigid earth retaining wall structures. Advantages of using EPS geofoams are well discussed by Horvath 1456 and Stark et al.

EPS geofoam is inherently multi-functional which makes it effective to use in a wide variety of applications. BRIDGE ABUTMENTS Geofoam is used to safely support highway loading without over-stressing the underlying soils and to reduce differential movement. Advanced Geofoam ground stabilisation giving you maximum control of your projects design timeline and costs.

Geofoam blocks are typically used as buffer layers behind non-yielding retaining walls to reduce the lateral earth pressure. Rely on geofoam for your retaining wall backfill and you will be more than pleased with its performance across posterity.
