Determination of filtration stability
Acc to EN 14497
The most significant limitation of the penetrability of a cementitious injection product in a fine crack
is the tendency of cement grains to agglomerate into an impermeable filter cake.
Clogging of the crack can occur by a combination of several factors such as; large cement grains
too large for the crack, poor initial dispersion of the cement grains, agglomeration when the grout
is exposed to filtration situations such as entrances to fins cracks or porous material.
The Suction filtration device can be used both in the laboratory and in field.

Suction device made of a non-corroding metal.
Filter for the suction device made of woven metal wire cloth with mesh apertures; 125 – 100 – 75 – 45 -32 µm
