Construction method for waterproofing of energy-saving self-protection roof

Abstract

The invention discloses a construction method for waterproofing of an energy-saving self-protection roof and belongs to the technical field of waterproofing of building. The construction method constructs by combining rigid and flexible waterproof materials and comprises the following steps of paving a hydrophobic sloped and heat-insulating layer, prepared from a waterproof agent, cement and heat-insulating light aggregates, on a structural layer of the roof; paving a leveling layer, prepared from the waterproof agent and cement slurry, on the sloped and heat-insulating layer; paving a flexible waterproof layer, prepared from a flexible self-adhesion waterproof roll, on the leveling layer; paving a protection layer, prepared from the waterproof agent and the cement slurry, on the flexible self-adhesion waterproof roll; paving a layer of metal roof acrylic acid high-elasticity waterproof paint on the protection layer, or leveling the protection layer by the waterproof agent and the cement slurry. According to the construction method for the waterproofing of the energy-saving self-protection roof, which is disclosed by the invention, the construction begins treatment of the leveling layer of a base layer, so that each layer is waterproof and is not subjected to water penetration, the waterproofing is permanent through once construction without hidden danger, the problem that leakage points are hard to be found out by the traditional waterproof construction is solved, and meanwhile, the functions of sloping, protection, heat insulation and heat preservation are achieved; the functions that the waterproof effect is permanent if the structure of the base layer is changeless and the likeare also achieved.

Description

technical field [0001] The invention belongs to the technical field of building waterproofing, and in particular relates to an energy-saving self-protective roof waterproofing construction method. Background technique [0002] Building waterproofing is the measures taken from the building materials and structure to prevent water from penetrating certain parts of the building. Waterproofing is mostly used in roofs, underground buildings, underground parts of buildings, inner chambers and water storage structures that need to be waterproofed. According to the different measures and means adopted, it can be divided into two categories: material waterproof and structural waterproof. Material waterproofing is to rely on building materials to block the passage of water to achieve the purpose of waterproofing or increase the ability to resist leakage, such as waterproofing of coiled materials, waterproofing of coatings, rigid waterproofing of concrete and cement mortar, and waterp...

AI Technical Summary

Problems solved by technology

Inorganic aluminum salt mortar waterproofing agent has good permeability, but it is acidic, corrosive to metals and will reduce the strength of the mortar, easily causing cracks, the waterproof layer is easy to fail, and the service life is not long, so it gradually withdraws from the waterproof market

Silicone-based mortar waterproofing agent is generally used for water-repellent exterior walls, but if cement sand is mixed and used in toilets and other places where unsaturated water appears, the effect will be very poor
