Conducting waterproofing work during frosty conditions with conventional materials can be risky and ineffective. Read this article to learn how to perform waterproofing during the winter months. The key lies in selecting materials and technologies specifically designed for low-temperature applications.<\/p>\n
Waterproofing the underground sections of a building in winter presents a significant challenge. Many tasks are conducted outdoors, and a considerable number of waterproofing processes, commonly referred to as \"wet works,\" become more complicated at temperatures below +5\u00b0C. The situation becomes even more problematic as temperatures approach or drop below 0\u00b0C.<\/p>\n
There are only a few waterproofing products available that can be reliably used under such cold conditions.<\/p>\n
There are several methods to deal with low temperatures on a construction site. One effective approach involves using mesh covers, curtains (tarps) on scaffolding, or specialized tents. The designated work area should then be heated with heaters. The heaters should be turned on approximately 24 hours before applying waterproofing layers to the prepared substrate.<\/p>\n

<\/p>\n
Carefully considering weather conditions and selecting products suitable for the prevailing temperatures are key factors in effective winter waterproofing. Most waterproofing products are designed for use at temperatures above +5\u00b0C. This is because bituminous masses are typically water-based dispersions, and cementitious slurries require mixing with water or use liquid water-based components (as in flexible slurries).<\/p>\n
Two-component bituminous products utilize both emulsions and hardeners, enabling the sealing layer to form through water evaporation and chemical reactions.<\/li>\n
Products such as BOSTIK C514 Terra 1K (formerly K11 Schl\u00e4mme Grau)<\/strong>, which also require quick setting, should be used with an understanding that their specified curing time applies to approximately 20\u00b0C. Lower temperatures and higher humidity slow down the curing process and strength development.<\/p>\n Thin-layer plasters such as acrylic, silicone, or siloxane plasters can be applied at a minimum temperature of +5\u00b0C. Modifiers are available to allow application even at temperatures approaching 0\u00b0C.[\/vc_column_text][vc_empty_space][\/vc_column][\/vc_row][vc_row][vc_column width=\"1\/4\"][vc_hoverbox image=\"261671\" primary_title=\"\" hover_title=\"BOSTIK BLOCK B525 TERRA 2K (Dickbeschichtung 2K A+B)\" hover_btn_title=\"Buy\" hover_btn_color=\"sky\" hover_add_button=\"true\" hover_btn_link=\"url:https%3A%2F%2Fwww.sanier.pl%2Fprodukt%2Fblock-b525-terra-2k%2F|title:Hydroizolacja%20BOSTIK%20BLOCK%20B525%20TERRA%202K%20(Dickbeschichtung%202K)\"][\/vc_hoverbox][\/vc_column][vc_column width=\"1\/4\"][vc_hoverbox image=\"257899\" primary_title=\"\" hover_title=\"PCI Pecimor 2k\" hover_btn_title=\"Buy\" hover_btn_color=\"sky\" hover_add_button=\"true\" hover_btn_link=\"url:https%3A%2F%2Fwww.sanier.pl%2Fprodukt%2Fpci-pecimor-2k%2F|title:Pecimor%202k\"]<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n [\/vc_hoverbox][\/vc_column][vc_column width=\"1\/4\"][vc_hoverbox image=\"244614\" primary_title=\"\" hover_title=\"Koester Deuxan 2K\" hover_btn_title=\"Buy\" hover_btn_color=\"sky\" hover_add_button=\"true\" hover_btn_link=\"url:https%3A%2F%2Fwww.sanier.pl%2Fprodukt%2Fdeuxan-2k-koester%2F|title:Deuxan%202k\"]<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n [\/vc_hoverbox][\/vc_column][vc_column width=\"1\/4\"][vc_hoverbox image=\"258422\" primary_title=\"\" hover_title=\"Koester Bikuthan 2K\" hover_btn_title=\"Buy\" hover_btn_color=\"sky\" hover_add_button=\"true\" hover_btn_link=\"url:https%3A%2F%2Fwww.sanier.pl%2Fprodukt%2Fbikuthan-2k-koester%2F|title:Bikuthan%202k\"]<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n [\/vc_hoverbox][\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space][vc_column_text]<\/p>\n Even in challenging weather conditions (temperatures below +5\u00b0C), essential waterproofing work can be carried out using suitable products. However, it is crucial to follow the recommendations outlined by the Building Research Institute Guidelines. These guidelines advise halting construction work in specific situations, such as low temperatures combined with strong winds, precipitation, fog, frost, or hoarfrost. This is not only a matter of ensuring proper material application and forming a waterproof layer but also of maintaining safe and hygienic working conditions.<\/p>\n If weather conditions allow, with temperatures ranging between +5\u00b0C and \u20135\u00b0C (and without precipitation, fog, frost, or hoarfrost), it is possible to use winter versions of KMB (polymer-modified bituminous) masses. These materials consist of two components: a bituminous emulsion with a lowered freezing point and a reactive powder. This composition enables construction work to continue during freezing conditions.<\/p>\n One drawback is the extended drying time. For example:<\/p>\n After conducting construction work in harsh weather conditions (temperatures between +5\u00b0C and \u20135\u00b0C, without precipitation, fog, frost, or hoarfrost), it is recommended to reassess the waterproofing work at the end of the winter season to ensure its durability and effectiveness.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n <\/p>\n <\/p>\n During slight frosts, frost can often appear on the surface. Such a substrate, as well as surfaces covered with a thin layer of ice or dampened as the temperature crosses the freezing point, are unsuitable for applying insulation materials. To correctly carry out waterproofing with products designed for winter conditions, it is necessary to increase the substrate temperature while simultaneously ensuring it is dried properly.<\/p>\n Proper care of waterproofing products is essential:<\/p>\n <\/p>\n The selection of waterproofing materials depends on the specific case. Therefore, it is best to schedule a consultation with our technologist, who will assist you in selecting products tailored to your unique situation.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=\"1\/2\"][vc_hoverbox image=\"260549\" primary_title=\"\" hover_title=\"Selection of Technology and Materials: Online or On-Site Consultation at SANIER (Recommended) During this consultation, you will learn more about:\" hover_btn_title=\"Find Out More\" hover_btn_color=\"sky\" hover_add_button=\"true\" hover_btn_link=\"url:https%3A%2F%2Fwww.sanier.pl%2Fprodukt%2Fdoradztwo-techniczne-pro%2F|title:Dob%C3%B3r%20technologii%20i%20materia%C5%82%C3%B3w%20izolacyjnych\"]<\/p>\n [\/vc_hoverbox][\/vc_column][vc_column width=\"1\/2\"][vc_hoverbox image=\"260001\" primary_title=\"\" hover_title=\"A consultation on technology and materials, conducted either online or in-person at the SANIER headquarters (recommended), will provide you with:\" hover_btn_title=\"Find Out More\" hover_btn_color=\"sky\" hover_add_button=\"true\" hover_btn_link=\"url:https%3A%2F%2Fwww.sanier.pl%2Fprodukt%2Fdoradztwo-techniczne-eco%2F|title:Dob%C3%B3r%20technologii%20i%20materia%C5%82%C3%B3w%20izolacyjnych\"]<\/p>\n <\/p>\n [\/vc_hoverbox][\/vc_column][\/vc_row][vc_column][\/vc_column]<\/p>\n","protected":false},"excerpt":{"rendered":" [vc_row][vc_column][vc_column_text] Winter Waterproofing How to Choose the Right Products and Execute Properly Conducting waterproofing work during frosty conditions with conventional materials can be risky and ineffective.

\nQuick-setting sealing slurries are often single-component products that must be mixed with water before application. Use water at a temperature of around 25\u00b0C for mixing. However, avoid using excessively warm water, as it can drastically shorten working times and negatively affect the shrinkage properties of the slurry.<\/li>\n<\/ul>\nThin-Layer Plasters<\/strong><\/h4>\n
