How to make the roof waterproof

1. Technical preparations before construction

Before the construction of the roofing project, the construction unit should organize the technical management personnel to review the roofing project drawings. Panjin waterproofing membrane shall master the detailed structure and related technical requirements in the construction drawings and prepare the construction plan or technical measures of the roofing project according to the actual situation of the project. This avoids leaving defects after construction and causing rework. At the same time, the project is carried out in a planned way according to the construction organization to prevent work omissions, confusion, and inversions from affecting the quality of the project.

2. Requirements for construction personnel and construction procedures

The waterproofing of roofing works must be carried out by waterproofing professional teams or waterproofers. Units without qualification certificates and non-waterproofing professional teams or non-waterproofing workers are strictly prohibited from waterproofing roofing works. The construction unit or supervision company should carefully check the construction personnel’s employment certificate. During construction, the construction unit shall conduct quality self-inspection, self-inspection, and self-correction according to the construction process and level, and make construction records. The supervision unit shall do the acceptance work of each process, and the next process and level operation can be carried out after the acceptance is passed. .

3. Quality requirements for waterproof materials

The waterproof material used in the roofing project should have material quality certification documents and be certified by the designated quality inspection department to ensure that its quality meets the requirements of the relevant national standards. After the waterproof material enters the construction site, the factory inspection report and the factory qualification certificate should be attached, and the production date, batch number, specification, and name should be indicated. The construction unit shall take samples for re-inspection in accordance with the regulations, and the sampling re-inspection shall strictly follow the witness sampling and sample delivery system. The construction personnel shall take samples on site and send them to the laboratory for testing under the witness of the representatives of the construction unit or the personnel of the supervision unit. After passing the re-inspection and submitting the re-inspection test report, it can be used in waterproof engineering. It is strictly forbidden to use unqualified waterproof materials in the project. Once unqualified materials are found, they should be evacuated from the construction site immediately.

What material is good for roof waterproofing

1, CPC waterproofing agent

This kind of material is a polymer nano material, its price is relatively good, ordinary people can also afford it, and the key is that the construction is not complicated, it will not cause damage to the building itself, and it can be directly applied. The time is relatively short, it will be completed in about 2 days. The effect is also relatively good, after coating, it can achieve a good waterproof effect.

2, JS composite waterproof coating

is also known as polymer cement-based waterproof coating, a new type of green environmentally friendly waterproof material strongly advocated by six ministries and commissions including the Ministry of Construction and the Ministry of Science and Technology. JS composite waterproof coating can be applied to new and old buildings and structure waterproofing projects, the construction is simple, the operation is not complicated, and the color coating can be carried out according to the needs. It has the high elasticity of polymer materials and the good durability of inorganic materials. After painting, it can form a highly elastic and high-strength waterproof coating film, which is non-toxic, odorless, and will not cause environmental pollution; it can also be constructed on a wet base surface, and it can be firmly bonded to various materials such as base surface and cement mortar. Together; construction on the facade, slope and top surface will not flow; the high temperature resistance can reach 100 ℃.

3, CH-108ZYY polymer cement

is also known as the base material of elastic cement. It is a two-component waterproof coating material composed of acrylic polymer emulsion, and added with special cement, inorganic curing agent and various additives. Its advantage is that it has good film-forming properties, water resistance and alkali resistance, etc., especially it can be directly applied on the wet base surface and cured to form a film.
