To provide a material so called "filled type fabric" or "spacer type knitted fabric" of civil engineering and architectural material and for use as a structural element for site work.

A spacer type knitted fabric comprises a lower layer 10 tightly knitted, an upper layer 12 loosely knitted, and a fiber 14 connected between the lower layer 10 and the upper layer 12. A cement powder is preferably introduced into a space 16 between an upper surface portion and a lower surface portion. The fabric is a fabric which can be solidified by the addition of liquid such as water. While the knitted fabric is flexible and can be shaped until the fabric is solidified, the knitted fabric is solidified after the material within the space 16 is solidified. An extended portion 24 of the lower layer 10 is extended over the upper surface portion 12 and is connected with the upper surface portion by a connecting fiber 26 having elasticity in which the extended portion is introduced into a direction of the other surface portion. Thereby, the space in the fabric is partially closed at a border portion of the fabric to prevent leakage of a solidifiable power material.
