At present, it is still widely used as a waterproof plan for public works.
The waterstop is waterproof.
When the concrete shrinks, cracks will appear, resulting in water leakage.
Due to the improper mix proportion of concrete, the impermeability grade is too low, or the concrete is not vibrated enough in a large area, resulting in concrete looseness and surface water seepage.
There are many reasons for water leakage in buildings, for example, water leakage phenomenon often occurs in the process of water supply and drainage buildings.
The main reason is that the waterproof scheme is not suitable and can not meet the waterproof requirements.
This phenomenon is also caused by the return of moisture on the wall, which is a mild symptom compared with water leakage.
Take Xiaobian’s home for example.
With the development of urban basements, rich experience and a set of relatively mature construction technology have been accumulated in the leakage stoppage of basement engineering, that is, gouging → drilling → pipe burial → grouting → recovery.
In the specific construction process, the supervising engineer should also pay attention to the following 10 points: the plugging work should be carried out after the construction precipitation stops and the groundwater level recovers.
At present, the common waterstop materials include rubber waterstop, plastic waterstop, neoprene plate waterstop and steel waterstop.
In order to avoid water leakage at the construction joint and post-cast strip, in addition to considering the ability of waterproof in the structural design, the waterstop is usually used for waterproof.
How much does it cost to repair the roof leakage of the toilet waterproof and waterproof balcony color steel room? The maintenance cost of roof leakage of the waterproof company, where to find the experience of professional waterproof and waterproof for 30 years? 10 years of warranty of the Yunnan Waterproof Company, professional waterproof and waterproof, and leakage and waterproof near the roof; Tel: 13724473304 Free door-to-door survey, bathroom kitchen minimally invasive repair without breaking bricks for two hours flash repair, professional bathroom kitchen without breaking bricks, minimally invasive waterproof plugging, balcony window exterior wall, basement garage, settlement joint, bridge culvert, floor, factory colored steel tile, elevator shaft construction, etc.
During the use of the house, the oil and gas layer on the wall fell off, especially at the bottom of the wall.
Among them, rubber and plastic waterstops are flexible materials with strong impermeability and deformation compliance, which are commonly used waterstop materials; Neoprene rubber waterstop is a new type of waterstop material, which has the characteristics of cumbersome construction, good waterproof effect, low cost and easy repair; Steel waterstop is generally only used in high temperature environment, but rubber waterstop or plastic waterstop cannot be used.
There is a layer of paint that bulges around, and it only needs to be gently touched to fall off.
On the other hand, the concrete around the waterstop is not compacted, and the groundwater bypasses the waterstop and seeps into the basement.
In large-scale structures, concrete cracks due to shrinkage deformation lead to water leakage.
For example, the new and old concrete surfaces are not well combined, or the performance of the waterstop material at the construction joints is not suitable for the construction conditions or the embedding process is improper.
One of the main reasons for deformation joint leakage is that the waterstop is improperly buried, cracked, displaced or aged.
Construction joints are formed during the construction of concrete structures.
Point leakage is caused by local vibration leakage of concrete or improper water stop measures of formwork through bolts.
Tel: 13724473304 Building leakage is not uncommon in our sight, it also belongs to a common phenomenon of building waterproof layer damage.
It has not been more than a year since the house was taken.
The waterproof material loses its waterproof function due to its low quality.

The coiled material waterproof layer is a flexible waterproof layer, which has good toughness and extensibility, can adapt to certain structural vibration and small deformation, and has good waterproof effect.
