Description

Technical Field

[0001] The utility model relates to the technical field of waterproof boards, in particular to a waterproof board used for underground waterproof projects. Background Art

[0002] The waterproof board used in underground waterproofing projects is a building material designed specifically to prevent groundwater infiltration. Its main function is to build a reliable waterproof barrier to ensure that underground spaces such as basements, tunnels, underground pipelines and other structures remain dry, and prevent various problems caused by moisture intrusion, such as structural damage, mildew, equipment failure, etc.

[0003] The widely used waterproofing boards in current underground waterproofing projects generally have a relatively single performance problem, which to a certain extent limits the comprehensiveness and durability of their waterproofing effects. These waterproofing boards often focus only on basic waterproof barrier functions, while neglecting environmental adaptability, durability, and the ability to work in conjunction with other waterproofing measures. Therefore, when faced with the complex and changing underground environment, these waterproofing boards often appear to be inadequate and unable to effectively protect underground structures from the threat of water erosion in the long term. Therefore, we propose a waterproofing board for underground waterproofing projects. Utility Model Content
