Method for repairing water seepage of thermal insulationouter wall

Abstract

The invention discloses a method for repairing water seepage of a thermal insulation outer wall. The location of a water seepage crack is determined by using a thermal imager; thermal insulation materials which seep into the periphery of the crack are removed, the crack is treated by high-pressure perfusion by using a waterproof adhesive, and the crack position is repeatedly brushed by using the waterproof adhesive to form an adhesive waterproof layer; before the adhesive waterproof layer is not completely solidified, a layer of alkali resistant mesh cloth is arranged on the solidified waterproof layer; and after the adhesive waterproof layer is completely solidified, thermal insulation mortar is applied on the surfaces of the alkali resistant mesh cloth and the adhesive waterproof layer,a sunken part is filled in, and after the thermal insulation mortar is solidified, the surface is repaired. The crack can be blocked by using the waterproof adhesive, and water in an inner wall is prevented from seeping into a thermal insulation layer; in addition, the thermal insulation layer is further rearranged, the original structure of a wall body is restored, and the thermal insulation effect is not affected; and a protrusion in the repaired wall is avoided, and the attractiveness is not affected.

Problems solved by technology

[0002] In high-rise buildings, due to the uneven professional skills of workers during the construction process, the construction process and technical details are not in place, the external wall leakage has become a common problem in many high-rise buildings, and the external wall skin has cracked to varying degrees. , falling off and other phenomena, rainwater enters the interlayer of the outer wall insulation layer through the small cracks and cracks on the outer layer of the wall, causing the insulation layer material to absorb water until saturated, and then repeatedly infiltrated for a long time, resulting in dripping and mold in the wall

[0003] In the existing repair process, the treatment of cracks is generally sealed with glue, that is, the cracks are covered with a glue layer. At this time, the glue layer will protrude from the surface of the wall and affect the appearance of the wall.

In addition, after long-term exposure to the sun, the glue layer will peel off from the wall surface, requiring repeated repairs
