How much is the price of exterior wall waterproofing and leakage, and how much is the exterior wall

When we carry out building construction, there is often a link that is quite important, it is the exterior wall waterproof leakage, generally speaking, it can be divided into rigid waterproofing and flexible waterproofing. Although there may be differences in the specific external wall situation, such as construction difficulty, construction situation, and construction materials, how much is the waterproof leakage of the external wall? Also, in the specific construction process, what are the methods and steps of waterproofing and repairing the leakage of the exterior wall?

1. How much is the waterproof leakage repair of the exterior wall?

If the exterior wall is waterproof, if there are not many leaks, it can be recommended to use a leak filler, which saves costs. If the leakage is severe or there are many leaks, it is recommended to re-do the waterproofing, which is more cost-saving. Generally, it costs more than 30 yuan to make a square meter of exterior wall waterproofing and leakage.

According to different building structures and wall materials, as well as the selected repair materials, the difficulty of construction, the area of the building, etc., these factors will affect the local area. (**** on the Internet, for reference only).

2. What is the method of waterproofing and repairing the leakage of the exterior wall?

1. Continuous irrigation part and cold connection: The continuous irrigation part of each layer and the cold connection, because the binding effect between the concrete cannot be expected, if it is contracted by the small ** and the concrete, the joint part will be cut off, forming a situation that is easy to produce rain leakage. According to this situation, we need to configure the corresponding proportion of concrete and wall paint, and use brushes to paint the exterior walls.

2. Cracks in concrete: The concrete poured on site has continuous filling joints or cold joints in each layer, which is easy to produce honeycomb or poorly filled parts, forming congenital shrinkage cracks. This is especially the case with long-span walls or continuous waist walls that protrude outwards from the wall structure.

According to this specific situation, we need to dilute the wall paint and use the wall brush to fill the cracks completely.

3. Around the opening: not only limited to the concrete structure, but also around the opening is the part that is easy to form weaknesses in waterproof construction. In the case of pouring concrete or using the tile formwork pre-pasting method, as long as you pay attention to the window sill, but in the case of stucco decoration or tile post-pasting, there will be cement floats or debris around the window, voids, and the top of the concrete is horizontal or reverse slope, etc., which will form a part full of shortcomings.

For the operation of exterior wall waterproofing leakage, due to the construction company, as well as the method used and the specific situation will have certain differences, the corresponding charges are often different, if you need to, you can consult some special teams or companies. For the method of waterproofing and repairing the leakage of the exterior wall, it is generally divided into three steps, first the continuous irrigation part and the cold connection, and then the crack construction of the concrete, preferably the construction around the opening, the specific method is detailed in detail, you can learn and learn.

What should I do if the exterior wall is waterproofed and leaked?

The first thing to do when discovering the leakage of the exterior wall of the house is to find the cause of the leakage, which can be analyzed from the materials selected in the construction of the house, so many modern residences are made of ordinary concrete perforated brick materials, and after the investigation and use of recent years, it is found that the exterior walls with ordinary concrete perforated brick materials almost all have external wall cracking and water leakage.

After finding the cause of the external wall leakage, you can take certain measures against it, for this type of external wall water leakage, the main thing is to repair the mortar layer, the surface cracks, the hollow drum layer and the water leakage micropores, so as to restore the waterproof protection function of the cement mortar layer. The specific method is to chisel the hollow drum part of the cement mortar layer, and then repair and level with polymer cement mortar, wherein polymer, cement mortar should be layered plastering, and the thickness is to repair and smooth the wall as the standard.

In the external wall leakage, if the gap on the surface of the wall is wider, it should be sprinkled with water to wet the gap, and then the inorganic waterproof plugging material is used to fill the gap, if the gap is narrow, you can choose to use polyurethane waterproof coating to paint the gap, the thickness of the painting process should be controlled between 1 mm, and for the width of the gap, it is based on whether the inorganic waterproof plugging material can be filled as the standard, if it can be filled, then it belongs to the wider gap, if not, it belongs to the narrower gap.

Precautions for waterproofing and leakage repair of external walls:

1. Exterior wall waterproofing is a branch waterproofing project to ensure that the structure of the building (structure) is not invaded by water and the internal space is not harmed by water. Exterior wall waterproofing works occupy an important position in the whole construction project.

Second, the exterior wall waterproof project is a large system of waterproof engineering, it involves materials, design, construction, management and other aspects, the task of the exterior wall waterproof project is to integrate the above factors, carry out a full range of evaluation, select waterproof materials that meet the quality standards, carry out scientific, reasonable and economical design, carefully organize technical forces to carry out construction and improve the repair and maintenance management system, so as to meet the waterproof durability and use function of the building (structure).

Dear, hello, the external wall leakage is 500 yuan per square meter. The cost of remediating external wall leaks varies depending on factors such as the cause, severity, location, size of the house, repair method, and local market**. The cost of repairing water leaks in external walls can be divided into the following aspects:

1.Testing cost: It is usually necessary to carry out water leakage detection first to determine the location and degree of water leakage, and the testing cost is generally between 100 yuan and 300 yuan square meters.

2.Material cover cost: according to the specific situation, different materials need to be used for repair, such as coatings, sealants, cement, etc., and the material cost is generally between 50 yuan and 200 yuan square meters.

3.Labor costs: including cleaning exterior walls, punching holes, painting, sealing, etc., labor costs are generally between 100 yuan and 300 yuan square meters.

4.Other expenses: such as the cost of erecting scaffolding, transportation tools, etc., need to be calculated according to the specific situation.

At the same time, it is recommended to choose a construction company with qualification certification and good reputation to ensure the quality and after-sales service of Shi Xiaoxian.

The cost of repairing water leakage in external walls has a lot to do with the cause, scope and degree of water leakage, so it is impossible to give an accurate **. Here are some of the factors that affect the cost of repairing water leaks in exterior walls:1

Causes of water leakage: The causes of water leakage in exterior walls can be varied, such as rainwater infiltration, wall cracking, clogged drainage systems, etc. Different reasons require different measures to fill the gaps, and the cost will be different.

2.The scope of the leakage: The larger the leakage, the more material and effort is required to repair the leak, and the cost will increase accordingly.

3.Degree of leakage: The more severe the leakage, the more complicated the measures that need to be taken to complete the leakage, and the cost will increase accordingly.

4.Region: Workers and workers in different regions have different wages and materials, so the cost of repairing water leakage on the exterior wall will also be different.

Generally speaking, the cost of filling gaps includes labor costs and material costs. If it is only a small area of water leakage, such as small cracks or local leakage, it may only need to use some simple materials, such as sealants, waterproof coatings, etc., and the cost is lower; However, if the leak is large or requires large-scale repairs and reinforcements, the cost can be high. Generally speaking, the cost of repairing water leakage on external walls is between thousands of yuan and tens of thousands of yuan, and the specific needs to be combined with the actual situation.

It is recommended that when you choose a leak repair service, you should first seek the best from multiple companies, and then compare and choose the most cost-effective service provider.
