For example, Xiao Ou received several inquiries about roof leakage of concrete factory buildings before, all because of the deficiency of traditional technology. After the waterproof layer on the roof of the factory building was destroyed, water flowed everywhere, but there was no leakage point. After a long time, the waterproof layer of the whole roof failed and had to be demolished and rebuilt.
Comparatively speaking, it is a better choice to use self-adhesive wet-laid polymer waterproofing membrane (pre-laid anti-adhesive method) on the roof of concrete factory buildings, which is also a topic that Xiao Ou will discuss with you today.
Technically speaking, the concrete is poured directly on the bonding surface of the coiled material, and the special bonding layer on the surface of the coiled material forms a permanent combination with the poured concrete slurry, which better solves the hidden danger of water channeling between the coiled material and the concrete structure.
Even if the membrane is damaged locally, it can be blocked by the concrete structure, and the water is limited to a small range. From this point, it can be seen that the new polymer self-adhesive waterproofing membrane can play a barrier role with the concrete structure layer to form a joint waterproofing system, which greatly improves the reliability of the waterproof layer and is convenient for later maintenance and protection.
From the material point of view, the cement slurry when pouring concrete can be bonded with the special polymer of the coil adhesive layer by wet curing reaction.
However, the bond strength will increase with the increase of concrete compressive strength. When the concrete reaches the initial setting stage, the adhesive layer of the coil has been completely wet cured with the concrete surface, forming a new waterproof layer.
This is also an important point that we attach importance to wet bonding technology, and the waterproof effect on the roof of concrete factory buildings is considerable.
Moreover, as far as the characteristics of the coiled material itself are concerned, reinforced concrete can be directly poured without a protective layer, which has outstanding advantages for rainy season construction or timely waterproofing.
But for concrete factory buildings, the ultimate consideration is waterproof effect and durability of coiled materials.
It is worth mentioning that the self-adhesive polymer coiled material has good alkali water resistance of concrete, is not infringed by domestic garbage and organisms, and is mildewproof and anticorrosive. Of course, it is best to cooperate with the professional construction team for waterproof treatment, "three materials and seven construction".
