Construction key points and process of non curing rubber asphalt waterproof coating

It can solve the problems of waterproof layer fracture, flexural fatigue or early aging under high stress caused by base cracking.

It creates excellent favorable conditions for shortening the waterproof construction period of basement; (5) Diversity and convenience of construction.

Due to the excellent extensibility and adhesion of the material itself, it can well adapt to structural deformation and will not cause damage to the waterproof layer due to structural change.

It can be applied not only to new waterproof projects, but also to repair damaged waterproof layer (injection waterproof layer regeneration system).

Safety and technical disclosure shall be made to the operators before implementation.

The coiled material shall be paved on the surface of the constructed waterproof coating, which shall be straight, flat and free of wrinkles..

Different from the traditional negative maintenance method, the coating can actively find the place with cracks, repair the damaged waterproof layer, rebuild the integrity of the structure, and restore the function of the original damaged waterproof layer.

Due to thermal expansion, cold contraction, vibration, displacement and settlement of buildings, it often leads to separation, delamination, aging and rupture of waterproof layer, resulting in waterproof layer failure and water channeling, which is easy to form potential leakage hazards at building deformation joints and structural defects.

Additional layer construction shall be carried out for the water outlet of the roof, pipe root, pipe orifice, internal and external corners, gutter and other parts out of the roof according to the design or specification requirements.

It can also be constructed on the wet foundation surface, which can reach the required thickness at one time, and the next process can be carried out without maintenance.

Before waterproof construction, the drawings shall be jointly reviewed, the detailed structure and key technical requirements shall be mastered, and the waterproof construction scheme shall be prepared and implemented after approval.

It can also solve the compatibility problem when the existing waterproof coiled material and waterproof coating are combined.

The base course of the waterproof layer shall be fully cured, and the surface shall be firm, flat and clean without peeling, sanding and other phenomena.

The product can not only be used as a waterproof layer alone, but also form a composite waterproof layer together with waterproof coiled materials.

Especially for the irregular structure and its edge seam, it can be formed at one time, there is no seam as a whole, and it is well bonded with the substrate to realize the overall perfect coating.

Use special tools to clean the laitance and building debris of the base course.

3) Detailed additional layer construction.

Product construction (taking the waterproof construction of flat roof as an example) 1.

Even if the base course (concrete) is cracked, it can maintain the re bonding with the base course.

4) Large surface coating construction.

After the construction of the coating layer, the coiled material waterproof layer shall be paved immediately.

Its products always maintain a viscous state without forming a film.

When it forms a composite waterproof layer together with the coiled material, the coiled material layer will not be subjected to stress, which ensures the integrity of the whole composite waterproof layer for a long time.

Construction process flow (figure below) 3.

Even if the base course is deformed, the waterproof coating has almost no stress transfer, and has always maintained adhesion with the base course.

For coating construction, the width of each operation shall be greater than 100mm of the coil width according to the conditions and requirements of the construction site.

It is especially suitable for waterproof parts with large deformation and projects with high waterproof grade requirements.

The base course shall be dry without open water or saturated moisture content.

2.

Level or compact the uneven and loose waterproof layer base with cement mortar or cement mortar mixed with polymer.

Key points of operation 1) base course cleaning.

Scope of application due to the excellent and unique performance of non curing waterproof coating, the product is suitable for non exposed waterproof works of buildings or structures such as subway, tunnel, culvert, dam, pool, road and bridge, toilet and bathroom, underground works, as well as waterproof and lining of subway, tunnel and basement, as well as non exposed roof waterproof maintenance works.

It is an active waterproof method.

During construction, mechanical spraying and scraping can be carried out after hot melting, and the construction can be carried out as usual in winter or rainy season; (6) It can also be constructed at low temperature: spraying construction does not limit the minimum construction temperature, which is an excellent low-temperature construction waterproof material; (7) Adaptability to structural deformation.

The non curing waterproof coating maintains viscous paste and has creep performance under the application state, closes the cracks and pores of the base course, and is suitable for complex construction surfaces; It does not solidify after long-term contact with air, and always maintains the characteristics of viscous colloid.

It has strong self-healing ability, sticky when touching, difficult to peel, and still has good bonding performance at – 20 ℃.

2) Base course repair.

Non curing waterproof coating can effectively solve the problems of waterproof and leakage repair of special parts like concrete (such as deformation joints) in building structure.

Technical preparation before construction.

At the same time, the viscosity of creep material can well seal the pores and cracks of the base course, solve the problem of water channeling in the waterproof layer, and greatly improve the waterproof reliability.

Wire Ring Clutch

Product construction characteristics at present, non curing waterproof coating has been widely used in various projects, and the construction characteristics of its products have been recognized by the waterproof industry, In terms of construction, the products mainly have the following characteristics: (1) non curing waterproof coating has excellent bonding effect with various waterproof coiled materials (including self-adhesive modified asphalt waterproof coiled materials, polymer modified asphalt waterproof coiled materials, synthetic polymer waterproof coiled materials, polyethylene polypropylene waterproof coiled materials, etc.); (2) The non curing waterproof coating can not only be used as a layer of coating waterproof, but also as a binder to paste waterproof coiled materials, but also form a composite structure waterproof layer with various waterproof coiled materials (including self-adhesive modified asphalt coiled materials, high polymer modified asphalt waterproof coiled materials, synthetic polymer coiled materials, polyethylene polypropylene coiled materials, etc.); (3) The non curing waterproof coating is bonded with various base courses to form a skin waterproof layer, which completely eliminates the occurrence of water channeling; (4) The non curing waterproof coating has low moisture requirements for the base course, and can be constructed without open water.

5) Lay coiled material waterproof layer.

General waterproof materials can meet the conventional waterproof requirements, but special parts prone to deformation have higher requirements for the use of waterproof materials.
