In the current construction and renovation, it can be said that the waterproof materials used are also various, such as waterproof membranes can be said to use very common, but to know that at present the type of waterproof membrane is also numerous, the following Xiaobian Let us introduce to you what kinds of membranes can be divided into, and what precautions should be taken when constructing waterproof membranes .
What kind of membrane can be divided into
1, asphalt waterproof membrane. Such waterproofing membranes are mainly made of natural material asphalt, kerosene asphalt, and petroleum asphalt, and are also of many types. They include asphalt oil stations, water emulsion asphalt, and rubber asphalt coatings. It is a relatively strong waterproof and corrosion resistant, durable use.
2, rubber plastic waterproofing membrane, this material it uses butyl rubber and polyurethane as raw materials, made of waterproof membrane, waterproof film, there are some water stop, itself has a better pull Extensive strength, it can be said that its elasticity is also good, the elongation is relatively good. And resistance to sleep habits and weather resistance is also worthy of respect.
3, cement waterproof membrane, when used, for cement has a relatively good waterproof, moisture, seepage effect, it can also be used in underground engineering, use these waterproof membranes for plugging, so say it The effect is exceptionally perfect.
4. Metallic waterproofing membranes, thin steel sheets, pressed steel sheets, and galvanized steel sheets can all be used as roofing sheets. The effect is waterproof, and thin steel sheets can also be used in large underground buildings such as basements. It can be said that its waterproof effect is also very good, there will be no moisture, leakage. A decorative pattern that is more common when used on a building.
What should pay attention to when waterproofing construction of coiled material
1. Scraping the grass-roots treatment agent on the grass-roots level requires a thin and uniform coating. It must wait until it is dry before it can be applied to the roll when it is not sticky;
2. The waterproofing of coiled materials should generally be constructed by paralleling the ridges upwards from the lowest level of the coils, so that the coils will overlap in the direction of water flow. When the slope of the roof is greater than 10%, the coils shall be laid perpendicular to the direction of the roof.
3. Paving method: peel off the release paper on the surface of the coiled material, and stick the coil on the surface of the base layer. The long side of the coiled waterproof material is overlapped and maintained at 50mm, and the short edge is overlapped and maintained at 70mm. The coil material is required to maintain the natural state of relaxation. Do not over-tighten. After the coils have been laid up, they should be fully compacted with a plane vibrator and the vertical part should be compacted with a rubber boring head.
4. Coil Bonding: After the web is compacted, lift the overlapping area and use a paint brush to evenly brush the lap adhesive. After opening the two adhesive surfaces of the web joint, apply Drying moment feels sticky, can be bonded, and then compacted with a rubber hammer tapping, so as to avoid leaks caused by slits;
5, waterproof layer construction temperature is more than 5 °C is appropriate.
Summary: Regarding what kinds of membranes can be divided into and what kind of precautions should be taken when constructing a membrane waterproofing. To know this, it is necessary to know the type of membrane is still relatively large. You have to choose according to the location, but during construction Some things that need attention should not be less, so that the effect of laying out will be more perfect.
Undermount Hand Made Sink, because the beautiful sex that hides in the water is a few stronger, the stainless steel thickness that handwork cistern place USES at the same time is met relatively thicker a few, this guaranteed the case that cistern does not appear easily leak.At the same time compare with traditional cistern,Undermount Hand Made Sink is stronger, more easy clean, more beautiful, and do the work more fine, not easy bad.
