Waterproof items are:
The basement is waterproof.
Waterproofing of roofs. Bathrooms are waterproof.
1. Material preparation and technical quality requirements.
All the waterproof materials in the basement must be waterproof materials that have been approved by the civil air defense quality supervision department and issued with a license.
The waterproof materials used in the underground waterproofing and toilet waterproofing projects must have passed the national quality inspection of the product qualification certificate and performance inspection report, and the variety, specification and performance of the material should meet the current national product standards and design requirements. Unqualified materials must not be used in the project.
The waterproof, thermal insulation materials used in roofing projects should have product qualification certificates and performance test reports, and the variety, specifications and performance of the materials should meet the current national product standards and design requirements.
2. Retest and quality control of waterproof materials.
All materials used for waterproofing projects, including special adhesives for bonding, must be sent to the material laboratory for material re-examination and inspection, and can only be used for this project after passing the inspection.
3. The impermeable concrete used in the basement, bottom plate and basement exterior wall must be sent to the material laboratory in advance, and the experimental report of the mix ratio must be submitted to the supervision for approval.
4. Technical disclosure and requirements for operation and skilled workers.
Before waterproof construction, the technical, quality and management personnel should first be familiar with the design requirements, and fully study and understand the construction specifications, construction plans and technical requirements. Be aware of the technical and quality acceptance standards.
The waterproof project is a special control process project, and the operation technical workers must have a certificate for the special type of waterproof work, and unlicensed personnel are resolutely not allowed to work.
Before the waterproof construction, the technical person in charge of the construction of the project, the project engineer, should personally carry out the construction plan to the technical management personnel and the foreman, and the technical disclosure, and the disclosure should have a disclosure record and signature.
5. The characteristics, difficulty, and construction difficulties of the waterproof project of the project.
The waterproofing project requires that the base layer must be dry, and it cannot be constructed when it is rainy. The characteristics are greatly affected by the seasonal construction. Therefore, it is necessary to grasp the weather forecast in advance, seize the sunny day, fight the cloudy day, and seize the time for waterproof construction.
On the outer wall of the basement, the water supply and drainage pipes pass through the wall openings, the wall screws of the formwork are many, and the warm passes through the wall openings, etc., which should be put with waterstops and water-stopping rings at different elevations and parts. Holes, yin and yang corners and other parts must be given additional layers or spring shouts for special treatment. These parts are difficult to construct, and it is not very convenient to operate, these are difficult constructions, and special attention should be paid to strengthening technology, quality, supervision, and inspection.
To put it mildly, it's actually useless at all. The certificates issued by the China National Talent Network and the China Professional Talent Network only prove that you have been trained and studied and have met certain ability requirements, but the certificate has no gold content.

Characteristics of waterproof and breathable membranes:
1. Air tightness: In 2005, the National Institute of Standards and Technology (NIST) released a report entitled "Investigation on the Impact of Air Tightness of Commercial Building Envelope on HVAC (Heating, Ventilation and Air Conditioning) Energy Utilization", which showed that the use of waterproof and breathable membranes can save up to 40% of the energy cost of heating and cooling in buildings without waterproof and breathable membranes. >>>More
