About PU foaming light weight banking method Foam Light M

This construction method is to foam hard urethane resin, "Foam Light M" with a necessary quantity, depending on land forms or civil engineering structures in contraction sites.


  • Light weight

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

  • Cost-saving

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

  • Stability

    It is safety because the foamed body is integrated and has no connection part or seam; it is also flexible to match with any bank or foundation.

  • Easy construction

    Easy construction: No need of large‐scale construction equipment, allowing human-powered construction.

  • Cost effective

    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.

  • Adherence property

    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 the hardening process.


  • Prevention of ground subsidence for banking construction.

  • Load alleviation against structures.

  • Cushioning materials against falling rocks.

  • The decrease of the earth pressure for retaining structures.

  • The banking construction for steep slopes.
