Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for repairing existing external walls of buildings and structures, such as mortar walls, roof decks, wooden slope walls, steel plate walls, slate walls, and the like.

In conventional buildings, when an exterior wall, for example a cement mortar wall, is cracked or peeled over a wide area, it is necessary to remove the exterior wall and then form a new exterior wall. This work required an enormous number of days and man-hours, and had the disadvantage of damaging the pillars and the foundation.

Additionally, during the construction period, it was necessary to set up tents and other temporary structures to prevent wind and rain from entering the building, and if the weather got too bad, residents had to be stopped. Furthermore, in order to save energy, conventional exterior walls lacked a heat-insulating structure, making them less comfortable to live in, and they also had the disadvantage of increasing heating and cooling costs. For this reason, when applying this type of heat insulation structure to a conventional outer wall, a method is known in which the space between the inner wall and the outer wall is filled with a heat insulating material. However, the disadvantage was that the entire wall had to be demolished, which required considerable cost and man-hours.

The present invention eliminates these drawbacks and inconveniences, and provides an exterior wall repair method that significantly improves livability, heat insulation, design, cost, and construction period.
