Damp walls are poor insulators causing
increased heating costs and health hazards. They can be a
nightmare for any building owner.
We want to help you protect the value of
your building. To do this, we have developed a one-step
system providing long-lasting protection against upward
moisture migration.
This system had to fulfill
the following requirements:
-
High
permeation rate through capillary passages
- Excellent
chemical resistance to acids and alkalines,
nitrates, sulphates, chlorides, etc. Excellent
resistance to oxidation, biological attack, UV
radiation and below-freezing temperatures
- High
resiliency under vibrations, earth tremors and
settling occurring during the drying out phase
The CavaStop 300 capillary barrier system
– a specially formulated, chemically balanced blend
of impregnating agents, synthetic resins, natural resins
and oils – fulfills the above requirements. It
provides a fast acting, water-impermeable barrier which
is practically inert to environmental attack.
Note: unlike silicification systems,
CavaStop 300 does not become brittle when solidified.
The CavaStop 300 system
provides numerous advantages over silicification,
including:
-
Even in walls
with high moisture content, e.g. over 60%,
CavaStop 300 permeates the finest capillary
passages.
-
Guaranteed full
impregnation in one step when the recommended
amount for the wall thickness is used.
Impregnation is complete within a few hours or
days, depending on site conditions. No topping up
is necessary.
-
Does not become
brittle on solidification.
- Smaller injection
boreholes.
-
Unaffected by
below-freezing temperatures and dissolved salts.

capillary barrier
system can be used with all mineral construction
materials including brick, sandstone,
sand lime
brick, concrete, quarrystone, etc. |
|
has excellent
permeation properties and can be used with
ventilated brick, hollow block brick, etc.
without need for prior filling with cement

is introduced
into the masonry by a pressureless gravity-feed
process. The supply cartridges are inserted into
injection boreholes angled at approx. 40°,
allowing the compound to permeate downwards
through the structure. |
 |
The superior
quality of CavaStop 300 is documented by official
materials test certification. |
|
WTA certified.
|
|
is highly
economical. Its application process is both easy
to use and safe. |
 |
Like all water
repellent compounds, CavaStop 300 is suitable for
waterproofing pores and capillary passages, but
cannot be used for sealing against pressing
water. |
|
The CavaStop 300
system allows renovation of walls without
structural modifications and static risks such as
those involved in chiseling or sawing procedures.
The building can be used throughout the injection process and afterwards.

is a simple, easy to process
and long-lasting horizontal moisture barrier and carries
a 10 year performance guarantee. Injection can be carried
out by the owner after receiving training and
instructions from the supplier
