Fabric Molding Frame

MODEM

New Technology Information System (NETIS) Registration Number:KK-150054-A

Outline

A fiber mat of good followability to the ground unevenness
Lightweight and easy to install.

MODEM forms a plate-like concrete structure by filling with fluid mortar or concrete in its double-layered chemical fiber cloth frame.

Characteristics

  • It can cover a wide area at once.
  • Since MODEM mats are permeable and dehydrate excess water quickly, the construction period can be shortened due to its short curing time.
  • A flexible fiber mat that follows well the unevenness of the ground.
  • It can be installed safely since the lightweight Fabric Molding Frame can be carried easily.
  • Underwater construction is also possible where filling can be done by pumping.

Types of MODEM

Standard type (type: R)

By injecting material between the double structure fabric to form a plate-like concrete layer, it is easy to build an impermeable layer on site.
* Subject to the watertightness of cast-in-site concrete.

Drainage type (type: D)

The single-layer drainage hole section arranged at regular intervals discharges the pressurized water from the back side, which has the effect of preventing the outflow of soil and sand and stabilizing the ground.
