Description

Technical Field

[0001] The invention relates to the field of waterproof materials, and in particular to a novel multifunctional modified asphalt waterproof coating and a production method and application thereof. Background Art

[0002] Waterproofing building cracks is a difficult problem in current projects. Crack grouting waterproofing is a waterproofing method that injects waterproof materials into the cracks to prevent water from penetrating through the gaps. This technology is usually used to repair cracks in concrete structures, basements, tunnels, subways and other buildings.

[0003] However, current waterproof materials do not take into account the repair of building strength.

[0004] Therefore, if there is a material that can repair the building's waterproofing while also assisting in considering the building's strength, it will make the building safer.
