What causes hollow walls? What materials are used for grouting repair?

What causes cracks in the wall? What kind of raw materials are used for grout repair?

First, the technical nature of the batch putty is not standard. The bottom layer of the wall is not cleaned before the batch of putty, and it is not solved as required. For walls of different raw materials, the reinforcement mesh is not set in accordance with the standard when connecting, the wall irrigation is not sufficient, and the wall is not divided or divided too large.

Second, the raw materials are not sufficient. Not soaked or not soaked enough before paving. Floor tiles (especially glazed tiles) should be soaked for more than 2 hours before paving, so that the floor tiles are sufficiently moisturized, and then removed to dry or wipe clean and flat.

If the water of the brick is not saturated, it will digest and absorb the moisture in the cement mortar too early, causing the mortar to collapse and cause the wall to hollow, and it will continue to endanger the compressive strength of the adhesive.

Third, the filler is not rounded. When the floor tiles are parquet, the cement mortar is not rounded or the wall tiles are not gently knocked to press the compactness. This is also a situation in order to better shoddy, save mixed mortar, that is, in order to better save time and sloppy.

There is also another situation that occurs when the project is outsourced, in order to better seek cheapness, the quality of the selected floor tiles is very poor, and the floor tiles are afraid of being smashed when compacted.

The "wall hollowing" in the quality of construction engineering generally refers to the hollowing of the wall due to the infirm adhesion and integration between the pavement, wall, ceiling interior decoration layer (batch putty or adhesive wall tiles) and the solid layer (concrete or wall) of the house, also known as "two-layer skin". Use a hollow drum hammer or a hard object to tap the putty layer and plastering layer to make a knocking sound for the wall to hollow.

The wall hollow drum microhole plate grouting solution process is a kind of concrete wall hollow drum, stone, wall bricks, thick steel plate wall hollow drum of the latest technology, the use of high pressure introduction of the basic principle, the high viscosity, high compressive strength, slightly large wall hollow drum repair raw materials——— wall hollow drum grouting epoxy resin into the internal structure of the wall hollow drum, fully automatic realization of the wall hollow drum range of grouting to improve the reinforced concrete, stone, wall bricks, thick steel plate and the bottom layer of the adhesion, comprehensiveness and durability, Achieve normal operating regulations. This process is a good way to repair all kinds of wall hollows, and the processing technology is cost-effective.

Causes of wall hollowing and cracking: Gypsum technology is not standardized. There is not enough material.

Lack of filling. When laying tiles, the mortar is not full or the tiles are not compacted. The proportion of mortar is unreasonable.

It is recommended to use hollow drum grouting resin grout treatment. The hollow drum position is fully filled to ensure the integrity and durability of the building and meet the requirements of normal use.

It may be that the wall is not well treated when pasting tiles, and the cement is not evenly smeared, the skills of the decoration master are not particularly in place, and the tiles are affected by the environment and temperature, so it will cause the wall to be hollow. Cement will be used for filling.

If there is a problem in the decoration process and it is caused by improper decoration, grouting resin will be used, and it is better to use this material for decoration.

If you want to use the grouting repair method to repair the wall hollow drum position, you should first punch holes in the wall hollow drum position, and then the grouting nozzle should be inserted into the hole, which mold is divided into five or six times to inject the grouting material into the grouting nozzle. 2. After the grouting is completed, it should also be observed in detail whether the grouting material is full, if it is not full, it will affect the repair effect of the hollow drum position of the wall. The grouting repair method can not only quickly repair the hollow position of the wall, but also the construction is simple and fast, and will not affect the user's positive and virtual skin often used.

Summary. Hello, the method of wall hollow drum grouting repair is as follows: You prepare tools and materials:

Wall scrapers, wire brushes, grouting devices, grouting pumps, cement, sand, permeable agents, etc. You check the wall first: use a wire brush and scraper to clean out the hollow drum on the wall, and record the checked hollow drum on a drawing, which is conducive to subsequent repair work.

Preparation of slurry materials: Cement and sand are mixed in proportion, and permeable agent is added and stirred evenly to prepare grouting materials. Grouting repair:

Use a grouting pump to inject the grouting material into the hollow drum of the wall until it is completely filled. Wait for curing: Wait for the grouting material to cure sufficiently, which usually takes 2-3 days.

Flattening the surface layer: Use a trowel to level the surface of the wall and deal with the joints with the surrounding wall. Polishing:

After the surface repair is completed, use sandpaper or a sander to polish the surface so that it is not significantly different from the surrounding wall.

Use a trowel to level the surface of the wall and take care of the joints with the surrounding wall. Polishing: After the surface repair is completed, use sandpaper or a sander to polish the surface so that it is not significantly different from the surrounding wall.

It should be noted that when entering the grouting repair of the wall, it is necessary to pay attention to safety to avoid the material slippery into the eyes, mouth and other sensitive parts. At the same time, tools and equipment are subject to a virtual balance safety check to ensure smooth operation.

The construction of walls is a relatively important process in the process of house remodeling, and there are many aesthetic procedures. After a while, the walls will bulge, which will greatly affect the decoration and aesthetics of the house. It also makes a lot of people feel very anxious.

If there is an empty wall in the house, it must be dealt with in time. The cause of wall hollowingAnd what are the ways to deal with it?

First of all,The cause of wall hollowingThere are many factors. Usually, when the undercoat is applied or the undercoat is not cleaned as needed to treat unusual walls. Therefore, it is essential to check the plaster substrate before placing the tiles.

If the pavement is applied when the pavement is applied, and if the back of the brick is used, and the hammer or soft hammer hits the cement mixture, then the back of the slab should be covered and firmly attached to the base layer of the wall.

Second,The cause of wall hollowingWhat, before laying, the bricks are not saturated or lack of enough water can cause this problem. BridgingNormally, the tiles must be submerged for more than 2 hours before paving to allow the tiles to be absorbed, dried or completely cleaned. If the bricks are not saturated, then the mortar that absorbs water molecules will be too fast, which will make the mortar shrink and appear hollow, which will also affect the strength of the joints.

First, for some ordinary vacuum drums, it is advisable to remove the sand and then compensate with quick ash. After drying, the dust putty is picked up again, but due to the location and other reasons, some hollow drums are difficult to excavate, and the stones with economic losses are large.

Secondly, for some wall bulges that are difficult to repair, it is recommended to use the perfusion repair method. It has a fast operating time and does not damage the base, especially in underground garages, factories and other places.

Generally speaking, the area of the empty wall can cause cracks in the coating, just like the scars on the face are very obvious, which can also affect the aesthetic effect, and it is not particularly safe, thereforeThe cause of wall hollowingIt is to be noted.

Wall hollowing refers to the phenomenon of blistering, warping, and bulging of the indoor wall due to improper construction technology or moisture. The wall bending and hollowing not only affects the appearance, but also causes great safety hazards, at least it causes a large area of cracking on the wall, and then there is water seepage and mildew, which affects the living experience and the repair cost is also high; In the worst case, it will cause the exterior wall to fall off, increase the risk of falling from height, and cause safety accidents. Shuchang.

Infrared thermal imaging equipment can be used to intuitively display the thermal defects of materials, structures and their tubing and chopping surfaces, and find the hollow drum leakage area in time. The detectors and movement components independently developed by Highchip Technology can quickly and non-contact, large-area non-destructive inspection of building finishing defects and leaks to ensure the safety of buildings.

1. Mortar wall hollowing: the hollow drum area should be cleaned first, and after the wall is soaked with water, the wall should be repaired with cement mortar;

2. Concrete wall hollowing: directly use a shovel blade to remove the hollow drum, and then apply a layer of concrete interface agent to the wall;

3. Painting the wall hollow: clean up all the dust. clean, then repair the wall with putty powder.

<> hollowing is due to the wall, ground base and ceiling layer are not cleaned, or due to improper treatment of the base layer, resulting in the stucco layer or the ground surface layer and the base layer or two different surface layers are not firmly bonded. In the long run, the ground will bulge, and the powder layer of the wall and ceiling will fall off, which will affect the use of users. Solution:

1. Use a cutting machine to cut out the hollow drum range along the hollow drum, the depth of the knife edge should be mastered, and slightly larger than the actual hollow drum range, and the chisel can not be chiseled, which may cause the hollow drum range to become larger and larger. 2. The base must be cleaned and moistened with water, repaired twice with 1:3 cement mortar, plastered, and then putty and wall painted.
