Description

The waterproofing and renewal method using a high elasticitic waterproofing film and a nano-ceramic paint}

The present invention relates to a waterproof repair method using a high elastic waterproof film and nanoceramic paint, in more detail, when the existing waterproof layer is broken due to acid rain, salt, cracks caused by temperature differences, etc. The present invention relates to a waterproof repair method using a highly elastic waterproof film and nanoceramic paint, which has been developed to easily repair and minimize durability at a minimum cost.

In general, in case of concrete building, water penetrates the structure due to expansion and contraction due to temperature difference and the effect of freezing in winter, so that the structure is cracked or its durability decreases rapidly. I need work.

The waterproofing method is divided into sheet waterproofing, waterproofing film, and composite waterproofing according to the construction method.The waterproofing film is applied to the concrete surface by repeating the liquid type waterproofing agent, or the flatness of the building surface due to the spreadability of the liquid itself. If it is not good, it becomes difficult to form a coating film of uniform thickness, swelling easily occurs due to moisture of the base, and there is a disadvantage in that responsiveness to cracks of the base is significantly reduced.

And, the sheet waterproof can solve the problems of securing the thickness of the waterproof layer and the correspondence to cracks among the disadvantages of waterproofing the coating, while it is difficult to secure the waterproof layer for the corners or protrusions of the complex structure.

On the other hand, composite waterproofing is a method of supplementing the disadvantages of the waterproofing and sheet waterproofing and maximizing the advantages, laid on the base surface of the waterproof sheet made of rubber asphalt, synthetic polymers or metal sheet or EVA and PVC It is a method of apply | coating a liquid coating film waterproofing agent.

Despite such a series of methods, the waterproofing layer is gradually exposed to the external environment which has a decisive effect on the lifespan of the waterproofing layer such as acid rain, salt, temperature difference, etc., and the degradation of the waterproofing layer is gradually progressing over time.

In particular, waterproof joints (heat joints or joints using reinforcing mesh and coating material), which are relatively weak parts of the waterproofing layer, are affected by external influence and undergo physical degradation, such as repeated shrinkage expansion due to temperature change, along with deterioration of the entire waterproofing layer. It will not be able to endure fatigue and will lead to breakage of the waterproofing layer, which will cause leakage to the structure.

The present invention has been developed to solve the above problems, the object is a high elastic waterproof film and nano-ceramic paint that can be easily and easily made at a minimum cost to repair or reinforce the waterproof layer of the existing structure is formed waterproof layer It is to develop waterproof repair method using.

In addition, in the construction of the waterproof repair method is to develop a waterproof repair method using a high-elastic waterproof film and nano-ceramic paint that can give additional functions such as resistance to shrinkage and expansion, and prevention of slipping and expansion as well as waterproofing.

In order to achieve the above object, the present invention provides a method for reinforcing and repairing an existing waterproof layer in which a sheet waterproof layer is formed on the bottom and outer walls of a structure made of concrete, and a film waterproof layer is formed thereon; In the case of overlapping waterproof layers, the sheet waterproofing layer and the coating waterproofing layer are removed and the concrete is exposed in the spaced-apart waterproof layer and in the horizontally spaced side, in the case of horizontal joint. A perforation process of perforating the perforation holes at regular intervals so as to; A debris removal process for removing debris including dust present in the perforated hole; A primer layer forming process of coating a urethane primer using an injector in the perforated hole; A first elastic urethane coating process including an upper surface of the urethane primer and applying the elastic urethane with a predetermined width about the perforated hole; A primer coating process of applying a primer on a base surface after the elastic urethane is sufficiently cured; It is characterized in that a series of processes of nanoceramic paint coating process for applying the nanoceramic paint on the entire surface is made continuously.

In addition, the urethane film attachment process for attaching a high elastic urethane film having the same elongation and tensile strength as the elastic urethane with the same width after performing the first elastic urethane coating process; The second urethane coating process for applying the urethane film to the upper surface of the urethane film again to the urethane film and the elastic urethane is further characterized in that it is further performed.

In addition, the perforated holes are overlapped with the waterproof layer on the basis of the center of the overlapping portion, in the case of the spaced apart waterproof layer and in the case of horizontal joints are spaced 3 ~ 4 cm from the center, 1 ~ 2 cm in diameter Perforated but characterized by being formed at intervals of 10 ~ 100 cm along the centerline.

In addition, in the first elastic urethane coating process, the elastic urethane is injected into the upper surface of the urethane primer,

It is characterized in that to be coated with an elastic urethane about 10 to 20 cm in width around the perforated hole.

As described above, the present invention has an effect of facilitating a work for repairing or reinforcing a waterproof layer of a structure in which an existing waterproof layer is formed at a low cost.

In addition, with the waterproof function, resistance to shrinkage and expansion, anti-slip, and various additional functions of blocking ultraviolet rays and infrared rays can be given to improve durability and prevent safety accidents due to sliding and to save energy.
