Its primary role is to <strong data-start=\"202\" data-end=\"277\">protect foundation walls from the harmful effects of water and moisture<\/strong>. Proper horizontal waterproofing is essential for ensuring <strong data-start=\"337\" data-end=\"361\">long-term protection<\/strong> against the negative impact of moisture, including <strong data-start=\"413\" data-end=\"473\">corrosion, mold, and the weakening of building materials<\/strong>. Ensuring adequate protection against moisture at the groundwater level <strong data-start=\"546\" data-end=\"625\">extends the lifespan of the building and preserves its structural integrity<\/strong>.<\/p>\n<h3 data-start=\"630\" data-end=\"713\"><strong data-start=\"634\" data-end=\"711\">Which Materials Should Be Used for Horizontal and Vertical Waterproofing?<\/strong><\/h3>\n<p data-start=\"715\" data-end=\"1004\">Since <strong data-start=\"721\" data-end=\"762\">horizontal and vertical waterproofing<\/strong> serve different purposes, they often require different materials. It is always advisable to consult <strong data-start=\"863\" data-end=\"905\">construction waterproofing specialists<\/strong> to choose the most suitable materials for specific <strong data-start=\"957\" data-end=\"1001\">site conditions and project requirements<\/strong>.<\/p>\n<p data-start=\"1006\" data-end=\"1049\">The most commonly used materials include:<\/p>\n<h3 data-start=\"1051\" data-end=\"1085\"><a href=\"https:\/\/www.sanier.pl\/en\/kategoria-produktu\/hydroizolacje-i-renowacje-en\/hydroizolacja-fundamentu-en\/hydroizolacje-bitumiczne-en\/\"><strong data-start=\"1055\" data-end=\"1083\">Bituminous Waterproofing<\/strong><\/a><\/h3>\n<p data-start=\"1087\" data-end=\"1440\">Bituminous waterproofing materials are <strong data-start=\"1126\" data-end=\"1175\">a mixture of aggregates, asphalt, and fillers<\/strong>, commonly available in <strong data-start=\"1199\" data-end=\"1244\">water-dilutable or solvent-based versions<\/strong>. These materials <strong data-start=\"1262\" data-end=\"1298\">have a high diffusion resistance<\/strong>, making it essential that the substrate <strong data-start=\"1339\" data-end=\"1382\">(such as
