The Fabriform process is a construction
technique in which fluid mortar or concrete is pressure-injected
into a fabric form made of high tenacity synthetic fiber.
(Japanese Patent: 636074, 133167,706813)
The fabric form is water permeable,
permitting the release of excess mixing water through
the fabric under injection pressure.
Accordingly the resulting reduction
of the water/cement ratio results in early stiffening
of the concrete or mortar, increases in density and compressive
strength,improvement in abrasion resistance and reduction
The Fabriform process is applicable to construction of revetments for protecting the shorelines of canals, rivers,and reservoirs and also for preventing the scour of canal and stream beds.
Fabric casting is used in the construction of groins,breakwaters,pipeline saddles and similar oceanfront and deep water structure. Pile jacketing is for structural restoration and protection of steel,wood and concrete piles.
The Fabriform process is described
in U.S. and foreign patents assigned to Construction Techniques,Inc.
(Contech) and is offered in Japan under exclusive license
by Asahi Chemical's Industry Co.,Ltd. which provides marketing
and technical services.
The fabric is woven of Asahi Chemicals high tenacity synthetic fiber which is particularly suitable for use in the Fabriform process. Experience record to date has been excellent.
The Fabriform revetment or mat is
a double layer fabric form woven of high tenacity synthetic
fiber yarn necessary to sustain injection pressure. Textured
yarn improves filtering characteristics of the fabric
and prevents loss of cement. Fabriform structures can
be installed in-the-dry and underwater with equal facility.
