Grouting waterproofing is high-pressure grouting waterproofing, due to factors such as uneven settlement of the building, resulting in deformation and cracking of the building structure, water leakage, for the repair of this situation, grouting waterproofing can be used.
The principle of high-pressure grouting construction: it is a special high-pressure grouting waterproof material injected into the concrete crack structure through high-pressure perfusion equipment at high pressure until all the gaps (including those that are imperceptible to the naked eye) are filled, and after encountering water (water injection) accompanied by cross-linking reaction, a large amount of carbon dioxide gas is released to produce secondary permeability, and high-pressure thrust and secondary permeation pressure will press the elastomer into and fill all the gaps to achieve the purpose of stopping leakage.
The characteristics of high-pressure grouting construction are: highly finished product, simple operation, reduced construction time, construction is not affected by weather, non-toxic and pollution-free, and cost saving.
Scope of application of high-pressure grouting waterproofing:
1. Plugging of deformation joints, construction joints and structural cracks in underground projects such as buildings, subways and tunnels.
2. Crack plugging of bridge piers, dams and hydropower stations, and reinforcement of external walls of concrete structures.
3. All kinds of water towers, pools, basements, family toilets, kitchen leakage and other seepage and plugging leakage.
4. Plugging leaks in tunnel excavation and mine construction, and plugging leaks in railways, tunnels and culverts.
5. Reinforcement of rupture zones and soft foundations. The waterproof plugging project adopts the advanced construction of "plugging, injection, sealing and prevention" measures and the combination of "grouting and waterproof coating".

The grouting waterproofing is very good, but the ** high point, the construction is a little troublesome. Need grouting process: 1. Find cracks first, find the leakage part, if you find that the base layer is wet, you must first clean up the stagnant water, and if the wall is dry, use an air pump to remove the surface dust.
2. Then there is drilling, first of all, the thickness of the concrete structure should be considered, and the hole spacing should be determined according to the actual situation of leakage.
3. Finally, the water-stopping needle is buried, and the water-stopping needle is the connecting part of the slurry injected into the crack.
4. When starting grouting, the pump pressure must be low, and then slowly increase the pressure and wait for the grout to flow out.
5. When the grout reaches the adjacent grouting hole, the grouting should be stopped and moved to the adjacent grouting nozzle to continue grouting .
6. In this way, the grouting is sequentially grouted, and then the first grouting nozzle is returned, and the grouting nozzle is removed after the end, and the hole left is closed with water without leakage.

Hello dear! We'll be happy to answer for you. Is it useful to use bathroom grouting waterproofing?
Kiss is useful, but not very useful. Waterproof glue injection in the bathroom can play a role in waterproof and plugging leakage in a short time, but it cannot completely solve the problem of water seepage in the bathroom. If the bathroom leaks, only glue injection will not be able to completely solve the problem, and there will be leakage problems after a long time.
Although the glue can be filled along the cracks and plugged in the gaps when the temporary object is left, when the water flows down, it will squeeze both sides, causing the water to spread outward and leak in the other direction. It is recommended to use waterproof paint or membrane to do waterproofing. If the bathroom upstairs is leaking, it doesn't make much sense to do glue injection work downstairs.
The upstairs residents should be allowed to rectify and re-waterproof the bathroom. Thank you for your patience. The above is all my reply, if you are satisfied with my service, please give a thumbs up, and I wish you all the best!
Peace and joy!

Grouting waterproofing is better than waterproofing. Grouting waterproofing is also commonly used in construction, grouting waterproofing is also known as high-pressure grouting waterproofing, mainly to take the power of mechanical high pressure, the polyurethane material.
When injected into a crack, it quickly disperses, consolidates, etc., and then the water flows completely into the concrete structure.
Plugging it will also achieve a role of stopping water and plugging leakage.
Introduction of grouting waterproofing
High-pressure grouting waterproofing, due to factors such as uneven settlement of the building, resulting in the building structure.
Deformation cracking, water leakage, for the repair of this situation, a new foreign plugging construction technology can be adopted. In terms of construction technology, the equipment is lightweight, the grouting process is simple and easy to operate, and it has strong adaptability to complex environments. In terms of waterproofing, because the grouting technology is to inject liquid into the cracks of the concrete, so that the filling is dense and bonded.
For aging, honeycomb and altering concrete, the grouting method can improve the compactness and strength of the concrete and achieve the effect of bonding and reinforcement. In terms of performance, the grouting reinforcing materials applied to concrete should generally have good comprehensive mechanical properties.
Good adhesion performance, material aging resistance, no pollution.

Summary. The grouting waterproofing effect is generally good. Construction features:
Highly finished product; Simple and quick to operate; Reduction of construction time; Construction is not affected by the weather; Non-toxic and non-polluting; Save construction costs. Using the high-pressure power of the machine (high-pressure pouring machine), the water-soluble polyurethane chemical grouting material is injected into the concrete cracks, and when the grout encounters the water in the concrete cracks, it will be quickly dispersed, emulsified, expanded and consolidated, so that the consolidated elastomer fills all the cracks in the concrete, and the water flow is completely blocked outside the concrete structure, so as to achieve the purpose of stopping water and plugging leakage.

The pipes in the basement are circling and flooding in. What to do?
Is it okay to use grouting?
The first is the surface layer method, first drain the water leakage, then apply polymer cement waterproof mortar at the watertight place, and if there are holes and cracks in the leakage, apply polymer cement on the back; The second is the grouting method, where huge cracks have appeared in the place of water seepage. Place a water pipe around the leaking crack for grouting. After the grouting is completed, wipe the surface with cement waterproof mortar.
That's generally okay, and it's used a lot in my hometown.

Is water-curing grouting waterproof reliable? Hello, I am glad to answer for you<> hydrophilic curing grouting waterproof unreliable grouting plugging, used for emergency water stopping, long-term leakage, according to the actual situation to choose whether grouting is needed. If there are cracks, then the grouting has a certain effect, but the time of the general pipe is not very long, if there are no cracks, it belongs to the slow seepage caused by the non-compacting of the concrete, the basic effect of grouting is not obvious, you can use the special backwater surface material UD001 high-strength special impermeable slurry and epoxy material together, this is a professional practice, the specific implementation depends on the cause of leakage and the structure to do a specific plan, not grouting is plugging, for professionals, there are many plugging methods, Treat each case on a case-by-case basis.
The bad thing is that the life of waterproof plugging is not very long, the durability is not high, and the cracks will continue to expand. Especially when there is a poor water-curing grouting of the eggplant, it will also cause the grout to be dry and not bonded to the original wall and produce gaps. Hope mine can help you <>

High-pressure grouting is useful for waterproofing and plugging. High-pressure grouting waterproof plugging is definitely useful, and many people will use this method to solve the problem of water leakage in the house. The effect is very good, first of all, before using high-pressure grouting waterproofing work, we must conduct a survey on the site, and if you meet the conditions.
In addition, it is necessary to determine the location of some leakage places, and then punch holes to clean the surface, and then grouting operations, which must be carried out by professional personnel.
Precautions for waterproof plugging with high-pressure groutingWhen it is necessary to pay attention to the grouting, the personnel operating the pump should always pay attention to the amount of grout filled, and at the same time observe the pressure change. In general, a sudden increase in pressure may be due to grout solidification, pipeline blockage, or due to the gradual filling of the grout into the settling joint, at which point the grouting should be stopped immediately.
It is normal for the pressure to rise steadily, but still within a certain pressure. Sometimes there is a drop in pressure, which may be due to the pores being washed open and a large amount of slurry entering the deep part of the settling joint, at which point the grout can be continued.

The grouting can not plug the leakage, and the expansion agent can be done well for a short period of time, so only the waterproof membrane can be used for waterproofing for a longer time.
Waterproof adhesive is originally there for this purpose. The effect is definitely there, but in my experience, it doesn't take long.
: Flexible waterproofing material refers to a waterproof material with flexibility. In addition to its excellent waterproof and impermeable properties with other waterproof materials, the flexible waterproof material has high tensile strength, high elongation, bending resistance and other properties, which can adapt to the natural deformation of the building, and the waterproof layer is not easy to crack. >>>More
