The invention provides a waterproof damp-proof and mould-
proof construction technology for a villa 
basement. According to the waterproof damp-proof and mould-
proof construction technology for the villa 
basement, firstly, the leakage condition is detected, and whether leakage stoppage is needed or not is determined according to the leakage condition; secondly, a waterproof crack-proof microcrystal layer is smeared for resisting seepage, and the waterproof crack-proof microcrystal layer has the advantages of being free of 
cracking, free of an empty drum, good in seepage resistance and cohesiveness, durable and 
environmentally friendly; and finally, mould resisting and damp resisting are conducted, the wall is painted with waterproof damp-proof and mould-proof microcrystal 
mortar three times, paste sweeping is conducted on the ground with waterproof damp-proof and mould-proof microcrystal pure 
cement paste, a waterproof damp-proof and mould-proof microcrystal fine aggregate concrete leveling layer is then manufactured on the ground, the waterproof damp-proof and mould-proof microcrystal 
mortar, the waterproof damp-proof and mould-proof microcrystal pure 
cement paste and the waterproof damp-proof and mould-proof microcrystal fine aggregate concrete all contain a waterproof damp-proof and mould-proof microcrystal additive, and the waterproof damp-proof and mould-proof microcrystal additive has good waterproof, damp-proof and mould-proof functions and is 
environmentally friendly and durable. In this way, the waterproof damp-proof and mould-
proof construction technology for the villa 
basement can permanently solve the problems of leakage, dampness and mould of the villa basement.
