Outline of On-Site PU Foaming Lightweight Banking Method
On-site PU foaming lightweight banking method is a civil engineering method
in which hard urethane resin “Foam Light W" is foamed in the required amountat the site and into a shape that matches the geography and structure.
Due to ultra-light density of 36 kg/m³, it enables to reduce the earth pressure
and load on embankment and earthen structure. It enhances a workability,enabling reasonable and speedy installation since it is foamed at the site.

2. Cost-Saving

5. Cost Effective

3. Stability

6. Adherence Property

The density with 36 kg/m³ is 1/50 lightercompared with that of sand and this ultra
light weight can realize a drastic load
alleviation of the earth pressure.

Cost-saving is possible due to foaming only
a necessary amount at construction sites.

It is safe because the foamed body is i
ntegrated and has no connection part orseam; it is also flexible to match with any
bank or foundation.

Easy construction: No need of large-scaleconstruction equipment, allowing humanpowered construction.

More economical construction of structure
can be realized because of its light weight;
No need of foundation work or improvement
work that used to be required.

One of the benefits of the product is self
adhesiveness and thus able to make a foam
which is strongly adhered to an object in thehardening process.

Material Characteristics①Compressive Resistance

Foam Light W has excellent compression
resistance and sufficient strength as bankingmaterial.

②Water Resistance

It has strong resistance to water intrusion andalmost no change in physical properties due toclosed cell structure of Foam Light W.

③Chemical Resistance

Foam Light W has excellent chemical resistance.
It does not dissolve in oils such as gasoline.

Condition※Animal oil is solid at room temperature and thus it is tested by heating it to 50℃.

Because Foam Light W is a thermosetting resin, it does not have a clear softening or melting point like otherplastic foams.
Each of the foamed bubbles is constructed independently and has excellent heat insulation effects.
