The EDO-EPS method is a lightweight embankment method that uses large Styrofoam blocks (product name: Tough Block) as the fill material.
This construction method utilizes the excellent features of Tough Block, such as its ultra-light weight, compression resistance, self-support, and earthquake resistance.

Styrofoam is 1/100th the density of soil, sand, or concrete, and is 1/10 to 1/50th the weight of other lightweight materials, making it easy to transport by hand. It can also solve problems such as settlement and lack of support in soft ground.
The compressive strength of EDO-EPS blocks was tested in accordance with JIS K 7220 and confirmed to have an allowable compressive stress of 35-350 kN/m2 or higher, which is sufficient to meet the required strength as an embankment material.
Since Styrofoam blocks are self-supporting, the stacked structure can be used as a freestanding wall.
Since it is lighter than earth and sand, it is highly safe even in large earthquakes.
In addition to shortening the construction period, ground treatment and temporary construction can be simplified, and the land required for construction can be minimized, contributing greatly to the reduction of construction costs.
No need for large construction equipment, and easy to install by human labor. It enables rapid construction even on soft ground or steep slopes where it is difficult to use large construction equipment. In addition, blocks can be easily cut on site, allowing for easy processing according to the terrain.
Shape and Dimensions
1.0m(W)×2.0m(L)×0.5m(t)
Tightening fittings connect stacked mutual tough blocks to prevent lateral misalignment and are important components to satisfy the effect of seismic resistance.
Tightening fittings are available in double-claw and single-claw types.
Double-jawed: Connecting points for tuff blocks in the vertical and horizontal directions (installed between each layer of tuff blocks)
Single jaw type: Where Tough Blocks are connected in the left and right directions only (concrete slab, structure, or other installation surface)
The imprint of “EDO-EPS” is stamped on the surface.
