Abstract

The present invention relates to a waterproofing method using functional mortar. A term of reconstruction is gradually shortened due to the rapidly changing climatic environments and the flaw and poor construction of various buildings. Since buildings should carry out waterproof construction, several waterproof methods, such as a urethane membrane, asphalt, liquid, or a sheet, are used at present. The buildings have a flaw in a waterproof layer before long after the waterproof construction is performed, and thus water is leaked from a rooftop, a basement garage, a porch, a water tank, or a water reservoir of the buildings, which causes discomfort of living. The waterproofing method is important in the future according to the change in various dwelling patterns. A material and a construction method should be specialized to extend the number of years, and anyone can easily carry out the waterproofing construction at a site. The functional mortar used as a primary waterproof layer and a base reinforcing material in the present invention is mixed with water at a site of a new building or repairing the building, and then is poured on an existing concrete or mortar floor, so that its surface becomes smooth by itself. The functional mortar is not peeled even by the placing thickness of 4 to 5 mm, thereby preventing the flaw in the waterproof layer of the building. The waterproofing method using the same protects a urethane membrane waterproof material which is widely used as a secondary waterproof layer, and can be used by a consumer without having a flaw for a long time.

The present invention relates to a waterproofing method using a functional special mortar

If the building is newly constructed and repaired, it is used as a waterproofing construction method on the roof of an apartment, an underground parking lot, an underground parking lot, and a liquid waterproofing urethane coating waterproofing method for asphalt application method is mainly used

Many buildings are exposed to chemical and physical phenomena due to climate change and external environmental factors, and the existing concrete and mortar floors are cracked due to the lack of surface strength of the structure floor

Currently, the waterproofing method currently used is the mortar which is used in the floor reinforcement work for the waterproofing work after removing and cleaning the foreign body on the existing floor.

This general mortar product has no fluidity and weak adhesive force, and has a defect that it spreads when it is applied thinly, and has a problem that the compressive strength and surface strength are weak and it can not penetrate the existing floor crack part

Currently, urethane coating waterproofing method, which is widely used for waterproofing construction, is important in the first floor pre-treatment and cleaning. However, most of the buildings in the present construction are flooded with concrete and mortar bottom surface. Especially, After 2-3 years after construction, the urethane waterproofing layer has been lifted from the poor bottom part. When the snow is coming from the roof slab of apartment buildings and various buildings, the bottom surface is cracked and cracked, rain water penetrates, Thereby shortening the life of the building structure due to leakage

We improved the construction method of foundation floor construction and converted the used materials into functional products, so that it is possible to use it quickly and easily at various sites and reduce the cost of construction.

.

In order to solve this problem, in order to solve this problem, before applying the urethane coating waterproofing material which is currently in use in the new construction and repair work, the functional special mortar is first applied to the entire floor surface to strengthen the surface of the existing floor, to form the

Functional special mortar is characterized by high strength and high adhesive strength. Prevention of cracking Debris prevention It is possible to adjust the construction according to each site. Waterproofing using functional special mortar composition so that the urethane coating waterproofing material, which is the second waterproofing layer, There is a purpose in providing the method.

As described above, according to the present invention,

1) When waterproofing the apartment buildings and various buildings by using the special functional mortar, it is possible to mix them with the mixer after pouring only the water to the products in the field. The durability is strengthened to give the product functionality. And the first waterproof layer is formed with 4-5mm for the installation. The second waterproof layer urethane coating waterproofing material is 3mm thick, but the functional special mortar is laid 4-5mm on the bottom, so that the urethane coating layer There was nothing wrong with applying 2 mm of ash, and it saved the cost of labor by reducing labor and material cost.

2) Urethane film This special functional mortar under the waterproofing layer of the product is filled with the original floor according to the conditions of the field floor, so that the irregularities and irregularities on the bottom surface of the construction floor are irregular. It has the effect of improving waterproofing quality

3) The effect of the process improvement is that when the water is poured into the functional special mortar only after the completion of the floor cleaning and cleaning work, the foundation reinforcement work of the floor and the formation of the first waterproof layer are completed.

4) The functional special mortar according to the present invention is first laid on the floor of the construction to solve the weakness of the existing floor, which is the weakest point of the secondary coating urethane coating waterproofing material, and weak surface strength. Waterproof layer has a long lifetime and it has the effect of giving convenience to consumers by reducing the material cost and management cost.

Cement which is widely used for the above materials is made of ordinary portland cement which can be easily obtained in the market in the country.

Also, it is possible to cause defects due to the presence of soil in the general sand that does not use the ordinary sand, and the silica sand is washed with clean water to remove the soil from the soil, and then the water is completely removed from the dryer

Existing concrete and mortar It has no floating phenomenon even if the special mortar is cast by 4-5mm in order to repair the floor surface and reinforce the surface strength. It increases the compressive strength and uses the floating fire so that it can flow into the gap between the existing cracks. (60-80mesh 0.6-0.25mm) fine particles were used for the silica sand specimens used to penetrate into the smoothness and cracks of the surface after casting.

Powder adhesive was used to improve adhesion and crude steel cement was mixed to make the hardening time faster than general cement

This product is poured only in water at various sites, mixed with mixer, spread on floor of existing concrete and mortar itself, and after curing, surface is smooth and high strength is maintained

In order to accelerate the initial strength and hardening time, it has good watertightness due to high chemical resistance and high degree of powdering by using crude steel cement. It has no problem even when mixed with good general cement and good compatibility with each other. Was used
