weber.tec 946
Silane-based injection cream for subsequent horizontal waterproofing of masonry against rising damp
Colours:
white
Storage:
The product can be stored at least 15 months in its original unopened packaging if kept dry and frost-free.
Fields of application
weber.tec 946 is used for the subsequent cross-sectional waterproofing of masonry against rising damp.
It is applied in boreholes in the low-pressure injection method.
Suited for masonries with a moisture content up to 95%.
Suitable for all common masonries.
Main features
- ready-to-use
- particularly suitable for hollow masonry, no uncontrolled run-off
- also suitable for lattice bricks and cellular concrete
- simple & safe use
- processing with manual gun, pressure sprayer (for ex. Gloria sprayer) or electrical pump
- convenient for masonries with a moisture content up to 95%
- water-based cream penetrates into the finest capillary pores
- no formation of harmful salts for the masonry
- belongs to the system “Simple & safe masonry repair system”
General notes
- Drying of the walls above the injection zone up to their balance moisture, if there are no dense wall coverings (remove renders and paint) and if adequate drying conditions are present in the treated rooms.
- Depending on the extent of damages, it may be necessary to implement additional measures, like either a functional vertical waterproofing on the exterior side of basement walls (for ex. the 2- comp. lightweight bitumen waterproofing thick coating weber.tec Superflex 10) or on the interior side of the walls (for ex. the 2-comp. reactive waterproofing slurry weber.tec Superflex D 2) and/or a damp-proof render (for ex. weber.san 953, san 954 or san 958).
- Take care that at least one horizontal joint is injected via a butt (vertical) joint.
- For wall corners drill holes on both sides of the walls.
- For application comply with the national standards and/or guidelines (for ex. above-mentioned WTA leaflet 4-10); if not issued and if necessary, request technical advice.
Special notes
- Do not mix with other building materials.
- Observe the Weber application tip ”Basement waterproofing - Old buildings - Easy and safe renovation of damp masonries”.
- In the case of fair-faced masonry, the risk of discolouration cannot be excluded; therefore, carry out a trial test in advance.
- When used with a pressure sprayer, note that the filled material is discharged via a connection at the bottom of the sprayer unit.
- When used with a curved spray lance, the bow including the nozzle thread must be removed.
- In the case of masonries with a large number of cavities, the resin should be processed using the patented ”wet-in-wet” injection method. For such masonries the first operation is to inject the borehole suspension weber.tec 942 (highly sulphate-resistant and low shrinkage cementbased mortar) through suitable packers prior to subsequent injection of weber.tec 946. This method creates a stabilized and solid injection area for the injection works and increases the alcalinity of this area which allows the resin to react.
