Is it possible to lay a plastic film between the roof slab and concrete for waterproofing purposes?
The roof is waterproof, or it is recommended to use professional waterproof material to do, in the prefabricated board paving finished, first with ordinary cement mortar leveling the ground, and then start waterproof.Roof waterproof, it is recommended to use rigid waterproof + flexible combination of waterproof construction. Thus, the utility model not only has the advantages of firm adhesion of the base surface, strong puncture resistance, high strength, but also can resist the stretching deformation of a certain extent of the base surface, and can meet the waterproof requirement of the roof for long time to be exposed to sunlight, rain and erosion.The specific construction method is to brush K11 waterproof slurry, flexible type, and then do a mortar waterproof agent protection layer, so that it can achieve good waterproof effect!Special reminder, the standard construction is a guarantee of good results, so must be in accordance with the requirements of standard construction, brushing thickness, height, interval time, etc., need attention.
Sure。 In the construction, the film can not be worn out, the effect is good, and the waterproof life is very long. I've done this before, and the film was good until the concrete was removed from the house. "It's been used for ten years.".
It is recommended that the precast slab be first poured with a diameter of 4mm or more, 200 spacing, two-way C20 fine stone concrete, 40mm thick, and then do waterproof two road, a little bit better insulation layer, and then make surface layer protection.
The seam of the prefabricated plate is very easy to crack. The plastic film is not good enough and is easy to pierce. Once it rains, it basically can't get waterproof effect;
