Abstract
Description
Technical Field
[0001] The invention belongs to the field of brick wall moisture treatment, and in particular relates to a method for treating moisture and mildew of brickwork. Background Art
[0002] In the past, the walls of old house buildings were not treated with moisture-proofing when they were first built, and the surface was very damp and prone to mildew. This was mainly because the capillary water in the soil seeped upward through the gaps in the bricks. This characteristic of the bricks and the existence of pores provided a channel for the infiltration of underground capillary water, alkali, salt and other substances, causing water vapor to seep upward along the walls, resulting in dampness and mildew on the walls.
[0003] When renovating old houses, in order to prevent the walls from getting damp and mildewed, it is necessary to demolish the existing brick walls and rebuild new walls. The disadvantages of this are: not only the workload is large and the cost is high, but it is also easy to damage the house structure. There is an urgent need for a method to control the moisture and mildew of brick masonry. Summary of the invention
[0004] The purpose of the present invention is to provide a method for controlling moisture and mildew of brickwork, which can solve the problem that the existing brick wall has no waterproof moisture layer or concrete ring beam, resulting in mildew on the indoor floor and wall. There is no need to demolish the existing brick wall or damage the exterior wall. The waterproof and moisture-proof functions of the moisture-proof layer of the existing wall are restored by combining grouting and filling in the indoor brick joints.
