Chemical damp-proofing systems to protect masonry
For damp-proofing masonry, professional users would require a caulking gun equipped with an injector nozzle as well as a water-repellent cream or a microemulsion concentrate.
Rising damp that penetrates masonry from below can quickly take a heavy toll on buildings: it rises through capillary action, damages building materials, increases energy consumption, and can cause mold.
Chemical damp-proofing with SILRES® BS products serves as a preventive measure as well as an effective solution for treating existing moisture damage. When injected into the masonry through drilled holes, they form a highly effective horizontal barrier that reliably keeps rising damp at bay.
Chemical damp-proofing – challenges and solutions
Typical challenges:
Our solution:
Chemical damp-proofing is an effective method to treat damp whereby holes are drilled into the masonry and injected with SILRES® BS microemulsion concentrates and silane/siloxane-based SILRES® BS Creme products. When injected into the masonry, they form permanent bonds to create a highly effective horizontal barrier against rising damp.
How a horizontal barrier with SILRES® BS works
Above the horizontal barrier created by chemical damp-proofing (yellow), the masonry remains dry, even if moisture pushes up from below. Through chemical damp-proofing, the active ingredient reacts with the silicate matrix of the building material and reduces surface tension. As a result, water ingress through capillary action is stopped, the wall dries out, and the masonry gains long-lasting protection against moisture.
FAQs
What is damp-proofing and when is it necessary?
Damp-proofing refers to measures that stop rising damp in the masonry and allow the walls to dry out. It is necessary when damage caused by damp – for example, spalling, mold, efflorescence – is conspicuous, or in the event of increased heating costs resulting from a loss in energy efficiency.
How does damp-proofing by means of masonry injection work?
In this process, boreholes are drilled into the masonry and SILRES® BS agents are injected. This forms a chemical barrier that blocks rising damp through capillary action. The masonry dries out.
What are the advantages of chemical damp-proofing with SILRES® BS?
This tried-and-tested method is efficient, versatile, and has long-lasting results – even in walls that are heavily saturated with moisture. It ensures dry, energy-efficient walls, is WTA-certified, and can be implemented without elaborate preparation of the existing structure.
