When the hot melt adhesive on the surface of the linoleum melts into bright black, roll the coiled material with a pressing roller to discharge the air under the coiled material and make it stick firmly.
Special attention shall be paid to the door and window openings, scaffold holes, reserved openings, cornices, awnings, balconies, window sleeves, downspouts and other details on the external wall.
These parts are weak points for anti leakage.
The leakage reason of the basement of the waterproof company is the root of the outer wall; At the wall parts on both sides of the deformation joint of the basement; Sewer pipe passing through the outer wall of basement; The heating pipe of the waterproof and leakage stoppage company passing through the outer wall of the basement; The junction of apron and external wall; Individual walls with loose masonry.
Many people have some misunderstandings about it.
If there is water seepage in the basement, first of all, find out the causes of water seepage in the basement and where it mainly occurs.
It is easier to seep water at the windowsill pressing plate, so pay more attention there.
Pipe orifice, internal corner and other parts shall be plastered into circular arc chamfer.
Roof waterproof and plugging price roof waterproof and plugging roof water seepage maintenance cost free brick smashing without wall dismantling one-stop service local company floor waterproof and plugging method roof waterproof kitchen balcony waterproof and plugging toilet water leakage free brick waterproof coating toilet waterproof and plugging without brick knocking; Telephone: 13724473304 free door-to-door survey, minimally invasive repair of bathroom kitchen without brick smashing, two-hour flash repair, professional bathroom kitchen without brick smashing, minimally invasive waterproof plugging, balcony floating window exterior wall, basement garage, settlement joint, bridge culvert, floor, workshop color steel tile, elevator shaft construction, etc., telephone: 13724473304 waterproof company waterproof plugging precautions: spray water to wet the surface before painting waterproof paint, and the base has strong water absorption, The painting is not smooth; The cured waterproof layer is prone to powder, no strength, pinhole and other defects.
It will cost a lot of money to set up a frame.
Before construction, the line shall be snapped and trial paving shall be carried out to make the coiled material paving position accurate.
If the outer wall is pasted with small-size ceramic tiles, there are too many gaps, which is more likely to lead to leakage because the waterproof is not handled in place.
The waterproof and plugging method of the basement of the waterproof company must find out the water leakage point and line through chiseling, and carry out targeted plugging; The principle of rigid flexible combination, expansion reinforcement combination and external rigid and internal flexible shall be adopted for the plugging of water leakage points and water leakage lines, that is, flexible grouting plugging materials that can be grouted, expanded and permeable in water must be selected internally, and rigid high-strength plugging agent shall be used for external plugging; The plugging of settlement joint must be carried out in the joint.
Water and other substances cannot be added to the waterproof slurry.
The professional waterproof and leakage stoppage company suggests that once there is water seepage on the external wall of the house, we must calm down and first see whether the external wall is still in the maintenance period.
The treatment measures for building exterior wall waterproofing of the waterproof company strictly control the construction quality of the exterior wall.
The waterproof layer shall be painted evenly.
Now the walls are almost made of concrete hollow bricks.
At the junction of concrete beam column and masonry, anti crack mesh shall be laid according to the regulations before plastering, and then plastering shall be carried out according to the requirements to prevent cracks in the joint of plastering layer.
The lap width of the coiled material of the waterproof and plugging company shall not be less than 100mm.
The combination of rigid and flexible, expansion and reinforcement and the combination of four plugging defense lines have a good effect, that is, from the inside to the outside, there are four defense lines: flexible, rigid, flexible and rigid; The leakage water inside the line pipe must be plugged when plugging; Only when the leakage stoppage of basement works is carried out from the inside of the project, the scheme is reasonable and the operation is correct, can good results be obtained..
People have higher and higher requirements for living environment, the continuous improvement of building technology and the combination with green buildings, many light wall materials have become the new normal of application.
The reason for the water seepage of the external wall of the waterproof company is that the gap in the window frame is not filled with mortar during the window construction, resulting in the infiltration of water from the window frame.
During the pouring construction, the vibration shall be carried out according to the sequence and direction, and the phenomenon of missing vibration shall not occur.
When laying the coiled material, it is required to heat the base course and the bottom surface of the material evenly at the same time during baking.
Next, the company will introduce the causes and treatment methods of exterior wall waterproof and leakage repair for everyone to understand.
Key points of waterproof and leak repair operation of the waterproof company the basement exterior wall waterproof adopts the “external prevention and external pasting (coating) method”, that is, the facade coiled material shall be paved or the coating shall be painted on the waterproof structure.
The construction site must have fire prevention facilities and shall not be constructed at the same time with the solvent coating.
When there is water leakage on the roof, exterior wall, basement, etc., we should first find out the cause of the water leakage, and then the professional construction team should adopt the corresponding waterproof and leakage repair method to deal with it.
The construction shall be carried out in strict accordance with the design and construction specifications.
The general solution is to brush waterproof paint on the exterior wall, but it is very troublesome.
Try to use glass glue to make a circle around the windowsill.
In order to ensure the construction quality of the exterior wall, the concrete mix proportion and water cement ratio shall be strictly controlled during the construction.
With the passage of time, the uneven rise and fall of buildings, weather changes, thermal expansion and cold contraction and other effects, there will be all kinds of micro cracks on the outer wall of the building.
There can be no open water at the grass-roots level.
The basement is a room located underground.
The waterproof coating shall not be painted too thick.
The strength of bonding and extrusion at the lap seam shall be subject to the extrusion of hot melt adhesive, and the spilled hot melt adhesive shall be scraped flat with a scraper while it is hot, and the edge shall be sealed tightly.
Rainwater can enter the wall along these cracks and affect the indoor wall, which requires timely water prevention and leakage repair of the outer wall.
To be clear, waterproof and leak repair is to repair the leakage with waterproof materials and waterproof plates.
Next, let’s learn about the relevant operation points and precautions of waterproof and leak repair of waterproof company for everyone to understand.
There are many water seepage cases in the damp and dark underground.
Next, we will give you a detailed answer about the water leakage in the basement, find out the reasons for the water leakage in the basement, and select the appropriate waterproof and leakage repair construction methods according to them.
You can also use an external wall waterproof transparent coating to brush waterproof around the windowsill.
