When pulling (hanging) the coiled material, pay attention to the alignment with the datum line at any time, and the pulling speed should not be too fast, so as to avoid that the deviation is difficult to correct.
To formulate a reasonable construction scheme, the waterproof engineering design generally only specifies the overall requirements of materials and engineering design.
In order to ensure that the waterproof project achieves the desired effect, special attention must be paid to the finished product protection.
When brushing the base course treatment agent.
Evenly brush the surface of the base course.
Roof waterproof and leakage repair is one of the most important links in the whole waterproof project.
It can be said that the quality of roof waterproof will directly affect our quality of life in the future.
protruding from the surface.
Jinshuai Waterproof Supermarket can meet the waterproof needs of different regions, different forms and different structural parts, and use high-quality products to serve high-quality projects.
The cleaning must be carried out at any time during the construction.
(Part of the articles are from the Internet) Thank you for your patience in reading this article 11-.
Generally, it shall be concealed 24 hours after the waterproof layer is completed.
Suitable waterproof materials shall be selected according to the grade, nature, function, structure and other characteristics of the building and the local environmental conditions.
Construction process.
Jinshuai Waterproof Supermarket covers SBS, self-adhesive, HDPE non asphalt based self-adhesive membrane waterproof coiled materials, high molecular polyethylene polypropylene (polyester) fiber waterproof coiled materials, waterproof coatings, waterproof accessories and other series of products, basically realizing full satisfaction of products and full coverage of functions.
Brush base course treatment agent: special base course treatment agent shall be used.
Paving self-adhesive coiled material: pop up the coiled material paving control line on the base course, and horizontally use the pull paving method (the side wall uses the hanging paving method) to pave large-area self-adhesive coiled material: lay the coiled material bonding face downward on the base surface, slowly tear the isolation film from the back from one end (the side wall is the upper end), and paste the part of the torn isolation film on the base course.
The air shall be exhausted to ensure that the coiled material is firmly pasted on the base course.
02 Precautions for roof leakage construction: optimize waterproof materials to improve the application rate of new waterproof materials.
The lap width of the coiled material shall not be less than 60mm for both long and short edges.
Of course, the material selection must be combined with the construction scheme, design and construction conditions.
When the material elongation is low, the point bonding method, strip bonding method or empty paving method shall be used to make up for it.
It shall be carried out in one direction, with uniform thickness, no bottom leakage and no accumulation.
The base surface is required to be clean: remove the sundries, oil stains, sand on the surface, and remove the stones, mortar bumps, etc.
Strength: In order to ensure that the waterproof layer is firmly bonded to the surface of the base course, the leveling layer is required to have sufficient strength, smooth surface, no sand and no peeling.
Generally, 3-4 people are selected as the team for waterproof construction, which is more suitable for the construction environment: the temperature during construction should be above 5 ℃, and it is not suitable for construction in a particularly humid and unventilated environment.
Before construction, a specific construction plan shall be formulated and implemented carefully according to the specific conditions of the site, such as environmental conditions, seasonal conditions, construction sequence, and operation requirements of specific parts.
The lap edges shall be rolled and bonded tightly.
The waterproof materials with high strength and high elongation shall be selected preferentially.
After pasting, roll forward and outward with force.
Sealing treatment of coiled materials: after the coiled materials are paved, the exposed lap joints and relatively weak parts (when there are many coiled materials cut in pipe wrapping and profiled parts) on the upstream of the coiled materials shall be sealed.
Finished product protection measures: finished product protection is the key to the success of the waterproof project.
The waterproof layer can only be made after the concrete or cement of the waterproof base surface reaches a certain strength, and there is no loose block.
If there are national standards or industrial standards, they must be implemented.
There are many kinds of new waterproof materials, forming different grades of high, medium and low, with different characteristics and respective application scope.
When the project may have deformation cracks.
Acceptance: After the waterproof layer is constructed and accepted, the next process shall be carried out as soon as possible to prevent the coiled material from bulging due to long-term exposure.
What are the key points and construction methods to pay attention to in the construction process of roof waterproof and leakage repair? 01 Manual preparation for roof waterproof and leakage repair construction process To ensure the quality, the waterproof work must be carried out by a professional waterproof team.
Strictly control the quality of waterproof materials, adhere to the use certification and testing system for the quality of waterproof materials, and confirm a batch of waterproof materials with reliable quality.
