There is water seepage at the casing through the floor and through the wall.
11 Water seepage hidden danger caused by wrong construction method the gas control conduit passes between the pipe and the casing 12.
The holes are not blocked in layers as required.
6.
The joint position of the waterproof coiled material is improper.
The exposed binding wire of the main construction, the pull screw of the external wall is not cut in place, the protruding concrete surface reinforcement is not cut flat, the hole is not treated, the concrete appearance quality defect is not treated, and the reserved reinforcement is not cut 3 Improper treatment of base course leads to water seepage hidden danger, internal corners are not plastered into arc shape, external corners are not ground into chamfer shape.
Subsequent construction will damage the waterproof layer by planting reinforcement.
There is no protective layer outside the deformation joint coil.
There is no protective isolation layer on the surface of the deformation joint coil.
7 Improper construction of waterproof nodes leads to potential water seepage.
A large number of engineering managers, directors and chief engineers have joined wechat.
The waterproof coiled material is not edge sealed as required.
5 Improper treatment of the details of the deformation joint forms the hidden danger of water seepage.
About the construction project management center (ID: shdc201505) construction project management center, It is the most professional communication and sharing platform for project managers, interpreting industry problems from the most professional perspective, capturing industry trends with the most keen sense of smell, and serving you with the most enthusiastic attitude.
The abandoned reserved holes are not blocked in layers as required.
This paper summarizes 13 reasons for the formation of water seepage hidden dangers in construction projects, so that we can compare them one by one and focus on prevention in construction.

13 reasons for the formation of water seepage hidden danger 1.
10.
The plane waterproof protective layer of potential water seepage caused by improper process insertion time is not constructed.
The end of the waterproof coiled material is not edge sealed as required.
The improper cleaning of the base course forms a water seepage hidden danger.
The slab surface crack water seepage structure construction joint water seepage 2.
After the waterproof layer construction is completed, holes are opened in the waterproof layer.
4.
The drainage slope of water seepage hidden danger caused by poor drainage is not correct, and the drainage is not smooth without drainage measures 13 Subsequent construction will damage the waterproof layer, forming a potential water seepage hazard.
Pipeline earthwork excavation will damage the coiled material waterproof layer.
The quality defect of the structure itself forms a water seepage hidden danger.
After installation, the surrounding of the pipe opening is improperly blocked to form a potential water seepage hazard.
The facade waterproof protective layer is constructed.
There is a hidden danger of water seepage caused by the blocking of the details of the embedded reserved casing.
Improper waterproof construction process leads to water seepage hidden danger, waterproof coiled materials are not firmly welded and fixed with steel nails, nail caps are not treated, adhesive fullness is not enough, lap length is not enough, bonding is not strong, internal corners are not attached with layers.
Water seepage is a common problem in construction engineering and it is difficult to cure it later.
What are you waiting for! At present, 100000 + people have paid attention to us.
It must be prevented in construction to avoid future problems.
Fixed stone keel will damage the waterproof layer by drilling holes in the waterproof protective layer.
Earthwork backfilling will damage the coiled material layer.
The concrete strength of the plane waterproof protective layer is not enough.
