Sealing to prevent rising damp

Over the past few decades, injection procedures for the subsequent production of horizontal impervious layers in the brickwork have established and proven themselves. These are effective, clean and, in particular, inexpensive procedures. The latest development in this field is the revolutionary cream technology.

During the development phase, it became clear that a concentrated cream formulation could overcome many problems of traditional horizontal seals.

The application benefits are evident. Compression makes little sense when using a cream-like material, because the consistency has no advantage here and/or could even collapse in an application of this kind. Therefore, cream-like material is predestined for a pressure-free application. With respect to processing, the consistency has the advantage that the material does not run out of a horizontal borehole. Complex slanted drilling, that always involves drilling through the masonry brick, is not necessary; instead, it is also possible to drill a horizontal, i.e very short borehole comfortably in the joint especially when there are continuous horizontal joints.

When comparing the properties of today's injection methods for the production of a horizontal seal and/or the available product systems, Kiesol C has extensive advantages over liquid product systems compared to other cream-like products on the market.

• Kiesol C is WTA tested and certified for pressure-free injection up to a degree of moisture saturation of 95%. The test report is available online.
• The previously required preliminary examinations required to select the liquid injection substances are no longer necessary because Kiesol C can be used at any degree of moisture saturation.
• The drilling effort and the material input, and required time are minimised thanks to the horizontal, streamlined boreholes.
• Due to the streamlined boreholes, subsequent backfilling with borehole suspension is no longer necessary.

Important parameters for the structural analysis need to be determined for the pressure-free brickwork injection, e.g. the degree of moisture saturation (DFG) and the free pore volume. The determined parameters define the selection of the optimum procedure technology and the correct positioning of the borehole series.

Kiesol is a long-standing specialist for pressure-free injection. Simple capillary saturation of the wall with Kiesol can be used up to a degree of moisture saturation of up to 80%, if the accessible residual pore volume is sufficient. Countless reference objects and numerous test certificates and examination reports verify this impressively. The active ingredient of the product is deposited in the capillary pores of the wall making them narrower. In addition, the walls of the pores are hydrophobized, i.e. made water repelling.
