What material is laid on top after the roof waterproofing material is laid 5

After the roof waterproof material is laid, a protective layer of concrete can be laid on top of it, which can ensure the waterproof quality and age. However, the protective layer must be made after the acceptance of the waterproof layer.

The roof is the highest and most rooftop layer of the house, if the roof is not waterproof, there will be water leakage indoors, affecting our home life experience. Therefore, the waterproof project on the roof is very important, we must find a professional waterproof construction company, and it is recommended to choose Keshun Waterproof Technology Co., Ltd.

More than 100 well-known real estate companies have signed strategic cooperation agreements, and the comprehensive strength of the industry ranks among the top three.

Generally speaking, a layer of concrete protective layer is played, and there are many roofs that directly expose the waterproof layer to the surface, but the disadvantage of this is that the waterproof layer is easy to age after a long time, reducing the service life of the waterproof layer!

If you want to bond the mortar with the waterproofing membrane, there are two series of waterproofing materials; 1. Double-sided self-adhesive series waterproofing membrane; 2. The coil with a covering on the surface (that is, the coil with sand on the surface of the coil). Other waterproofing materials, no matter how you do it, have an isolation layer; There are many kinds of waterproof materials for coatings, but they must have a double waterproof layer for roofing.

Hello dear, happy to answer your <>

Answer, after the roof waterproofing material is paved, a layer of asphalt is laid on top of it, and the most basic preparations are made first. Then the base layer is cleaned up, and then the base treatment agent is painted, and the additional layer can be completed with modified asphalt membrane hot melt and pasted with the membrane. Hot-melt edge banding, do waterproof water storage experiments.

Check the record of the rent letter and the maintenance of the waterproof layer. Protect the finished product. The best way to waterproofing the roof is as follows:

1. Make the most basic preparations first. 2. Clean up the base layer to ensure that there is no dust and construction debris on the base layer before construction. 3. Then brush the base treatment agent, if the polymer modified asphalt membrane is used for construction, we must use it in accordance with the regulations, after the base treatment agent is mixed evenly, it is applied to the surface of the base with a long roller brush, and the coil can be paved after 4 hours under normal circumstances.

4. The additional layer can be completed with modified asphalt membrane hot melting, and the additional layer is applied to the parapet wall, water drop, pipe root, yin and yang angles, etc., and the area of the additional layer should be in line with the provisions of the vertical meter. 5. Paste the coil. 6. Hot melt edge sealing, and heat the overlapping places of the coils with a hot melt gun.

7. Do waterproof water storage experiments. 8. Check the records, this work is usually accepted by professional quality inspectors and recorded. 9. Maintenance of waterproof layer.

10. Protect the finished product. If the roof leaks, you can also pour a layer of concrete directly on the top of the roof wheel, or you can pour a layer of concrete directly on top of the waterproof membrane after making the waterproofing membrane.

Can you lay cement mortar on the roof waterproof membrane? Hello, I am glad to answer your <> pro The roof waterproofing membrane can be laid with cement mortar on the waterproof membrane, but it must be ensured that the waterproof membrane has been completely dry, and white cement can not be selected when laying cement, because white cement has no waterproof function, and there will be cracking after a long time, which will cause damage to the waterproof layer. If Li Yu wants to lay cement on the waterproof membrane, he must choose cement with a relatively high density, which can prevent the cement from cracking, because the higher the density of the cement, its frost resistance and high temperature resistance can be very good, and it can withstand the wind, sun and rain.

If necessary, the cement mortar protection on the waterproofing membrane is to prevent the waterproofing membrane from being damaged by external forces and affecting the waterproof effect. There is also a cement mortar protective layer to cover the waterproofing membrane, which will have the effect of slowing down the aging of the waterproofing membrane, improve the service life of the waterproofing membrane, thereby prolonging the renovation of the waterproof floor socks and the cost of renovation, I hope I can help you <>

Do you have any other questions?

Hello, dear, I'm glad to answer for you, yes. If you want to lay cement mortar on the waterproofing membrane, you need to pay attention to the following points:1

Before the cement mortar is applied to the waterproofing membrane, the rotunda needs to be coated with a special interface agent on the surface of the membrane to enhance the adhesion and flexibility between the membrane and the cement mortar. 2.After applying the interface agent, the mortar should be spread within 24 hours to avoid the reduction of adhesion after the interface agent dries.

3.When laying mortar, it should be ensured that the mortar is uniform and dense, and there should be no hollowing, cracks and other phenomena. In short, it is recommended that when entering the waterproofing project on the roof of Orange Zhaoyinxing, the appropriate waterproofing membrane and upper laying material should be selected according to the specific situation, and the construction should be carried out in strict accordance with the requirements of the manufacturer to ensure the effect of the waterproof layer.

Hello, dear, the roof can be waterproofed first to do waterproof asphalt coating and then paved with waterproofing membrane. It is generally not recommended to do this, the effect is not great, the general practice is to do the waterproofing membrane first in the asphalt waterproof coating! It can ensure a good and lasting anti-pickpocketing effect, and the construction is seven-pointed.

And good materials plus good construction. I hope it will help you, not only to protect the waterproof coating layer, but also to strengthen the waterproof effect. One point to pay more attention to here is the quality cavity and construction of the membrane.

It is more reasonable and insured: first deal with the base surface of the roof, brush the waterproof coating, completely finalize the coating with the coating, make a cement mortar protective layer, and then make the membrane waterproof layer.

Can the roof be covered with cement after waterproofing?

Hello dear, yes, the roof can be waterproofed and can be paved with cement. It is regarded as a protective layer of the waterproof layer, which can extend the life of the waterproof layer, but pay attention not to damage the waterproof layer during construction. Waterproof materials refer to materials that prevent rainwater, groundwater, industrial and civil water supply and drainage, corrosive liquids, and moisture and vapor in the air from invading buildings.

The parts of the building that need to be waterproofed are mainly the roof, wall, ground and basement.

Kiss! Hello, happy to answer your <>

Pro-roof waterproofing, you can first do waterproof asphalt coating, and then pave waterproof membrane, which can play a better waterproof effect. However, if it is an unknown material, it is best to do an experiment first to see if the two materials will react and lose the waterproof effect. The method of waterproofing the roof with asphalt:

1. Deal with the grassroots first. Remove the original decorative materials, clean up the floating soil and cement, and require a smooth and dry surface. 2. Pave waterproof coating.

Brush a layer of modified asphalt on the base layer of waterproof treatment, lay a layer of glass silk cloth, and then repeat the brushing, and finally paint the second layer of glass silk cloth again, and the water treatment of the anti-wheel is completed. The waterproof coating should be evenly painted, the glass cloth and the waterproof layer should be tightly closed, and there should be no leakage, bulging and falling off, otherwise the waterproof effect will be affected. If polyurethane is used as a waterproof coating, there is generally no need to add glass cloth, as long as it is repeatedly brushed 2-3 times.

Because the polyurethane coating itself can form an elastic protective film, it has a certain tensile resistance. In order to improve the waterproofing effect, a layer of glass wire cloth can be laid, but the cost will increase. It should be noted that when doing ground waterproofing, the waterproof paint and glass cloth should be brushed to the wall 20-30cm from the ground to prevent leakage at the junction between the wall and the ground, so as to form a closed and firm overall waterproof layer.

For the walls of the shower room, soft lightweight walls and indoor walls that are afraid of leakage, it is necessary to paint the waterproof paint to the meter of the wall or paint the whole wall to prevent the wall from leaking. 3. Do the "water masking" test, which is an important inspection means to check the indoor waterproof quality. After the waterproof project is completed, seal the door and the drain, fill the room with water to reach a certain liquid level height, and if the liquid level does not drop significantly within 24 hours, it is qualified.

After the completion of the "water shielding" test, make another layer of cement mortar protective layer on the waterproof coating layer, taking care not to damage the waterproof coating layer that has been made. After the protective layer of cement mortar is dry, you can pave the wall and floor tiles or spray paint on it for normal decoration, so as to avoid unnecessary trouble in the decoration process. Hope mine can help you <>
