Reinforced with glass fibre and featuring an aluminium insert, it guarantees exceptional durability and resistance. It is coated on both sides with PE film, providing additional protection against external factors. The membrane is easy to install \u2013 it is laid \u201ecold\u201d, making the installation process quick and safe. Using this system eliminates the need for the tedious priming of the substrate with bituminous preparations. This modern waterproofing membrane allows work to proceed immediately to the next stages once the joints have been sealed, which eliminates production downtime and significantly speeds up the completion of the project.<\/p>\n<h2>Dimensions of the Katja Sprint membrane:<\/h2>\n<ul>\n<li><strong>thickness: <\/strong>0.9 mm,<\/li>\n<li><strong>roller surface area:<\/strong> 40 m\u00b2,<\/li>\n<li><strong>length:<\/strong> 32 metres,<\/li>\n<li><strong>width: <\/strong>1.25 m.<\/li>\n<\/ul>\n<h2>Why is it a good choice?<\/h2>\n<p>Thanks to its high sd value (\u2265 1,500 m), it effectively blocks the flow of water vapour, whilst its self-adhesive and self-sealing formula makes installation quick and easy. The Katja Sprint membrane is characterised by high resistance to mechanical stress, whilst its high performance makes it a cost-effective choice. Furthermore, the fact that no open flame is required during installation, combined with its radon-blocking properties, makes Katja Sprint a safe and durable option for protecting terraces, cellars and other surfaces vulnerable to damp. This waterproofing membrane guarantees a fully watertight system, partly due to its ability to adapt easily to complex substrate details, which confirms its versatility in the waterproofing of floor slabs and foundations.<\/p>\n<h2>Katja Sprint sealing membrane \u2013 applications<\/h2>\n<p>The Knauf Katja Sprint membrane is a high-quality damp-proof solution that effectively insulates internal floors and ceilings in buildings. It provides excellent protection against rising damp from the ground and eliminates the risk of radon penetration. Thanks to its versatility, it is also ideal for insulating ceilings above rooms with high humidity levels, such as bathrooms or cellars. Furthermore, it acts as an effective barrier against residual moisture, particularly in concrete ceilings, ensuring long-lasting protection for the building structure. A properly installed waterproofing membrane on a terrace (under the screed) effectively blocks the transfer of moisture and water vapour, preventing the degradation of finishing layers. This material does not require the use of open flames, which allows work to be carried out safely around structural elements and installations.<\/p>\n<p><!-- pkc-yt-embed:Wqr0tBITmBY --><\/p>\n<div class=\"pkc-yt-embed wp-block-embed is-type-video is-provider-youtube\">\n<div class=\"wp-block-embed__wrapper\"><iframe loading=\"lazy\" title=\"YouTube video\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/Wqr0tBITmBY\" frameborder=\"0\" allowfullscreen allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\"><\/iframe><\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>A polymer-bitumen waterproofing membrane with an aluminium insert, reinforced with glass fibre.
