| SYNTHETIC
RESIN, HORIZONTAL DAMP BARRIER
AGAINST RISING DAMP AND
SALT POLLUTION IN WALLS |

DESCRIPTION
The Koster CRISIN
76 is a very thin synthetic
resin. It penetrates deep
even into the tiniest
capillaries and pores
of the subtrate. The CRISIN
76 distinguishes itself
by a very low specific
gravity and a surface
tension that is much lower
than that of water. The
result is that CRISIN
76 displaces the water
in the capillaries. It
coats the capillaries
and makes them water repellant.
The curing of the injection
material is independent
of the curing process
in the masonry. The CRISIN
76 remains flexible even
after its full cure and
does not deteriorate.
One of the unique properties
of this resin system is
that it is neutral and
causes no efflorescence
on the substrate surface.
The CRISIN 76 resists
all conventional aggressive
masonry compounds, as
well as acids, alkalines
and salts. It resists
them already during application
and after completion of
curing process. CRISIN
76 does not attack the
reinforcing steel. Contrary
to other pressureless
injections, the CRISIN
76 method requires small
borehole diameters.

FIELD OF APPLICATION
This borehole injection
method is used to install
a subsequent horizontal
barrier in any mineral
construction material
where the original rising
damp barrier has failed.
It seals off rising damp
especially in very damp
and salty substrates.
APPLICATION
1. Drill holes according
to table on following page.
Holes should be drilled
horizontally into the lowest
visible mortar joint (between
the brick layers or at least
5 cm from the ground). Holes
should be drilled so that
5 cm of the wall thickness
remains (e.g. 30cm wall
= 25 cm drilling hole).
2. Use vacuum or compressed
air to clean holes
3. Measure, cut and insert
capillary rods, when inserted
completely, they must be
visible at least 8 cm outside
the wall.
4. Attach the capillary
angles, some might have
to be cut to fit properly.
5. Saturate the KÖSTER
Capillary rods with water.
6. Attach the Koster CRISIN
76 cartridges.
7. After leaving cartridges
until empty (3-48 hours),
remove cartridges, cut capillary
rods, remove capillary rods
and angles.
8. Fill holes using a suitable
mortar .
